[3] α-β-unsaturated sulfonamides
[4] Cancer is a leading cause of death in the United States and around the world. In order to be usefully used, the new chemotherapeutic agent must be one that has a broad spectrum of activity and a marked therapeutic index. Styrene-ω-sulfonanilides have been prepared by reacting styrylsulfonyl chloride with aniline (Bordwell et al. , J. Amer, Chem. Soc. 68: 139, 1946). This and certain other styrene-ω-sulfonanilides are common housefly musca domestica el. Chemosterilansts to Muscadomestica L. Possible, have been prepared by the synthesis of kneubenagel-type (Oliver et al., Synthesis 321-322, 1975).

No bar In particular, no anti-cell proliferation or anticancer use has been suggested for this type of compound.
[9] In particular, there is a need for new cell antiproliferative and anticancer agents useful for inhibiting the proliferation of cancer cells and / or killing cancer cells. In particular, there is a need for a therapeutic agent that selectively kills proliferative cells, such as tumor cells, but not normal cells. There is a need for effective antitumor agents for a wide range of tumor types.
[10] Health risks of ionizing radiation
[11] Ionizing radiation is mainly adversely affected by cytotoxic action on cells and tissues. The human body is primarily exposed to ionizing radiation, either during treatment (chemotherapy) or by accident or by exposure to the environment.
[12] The main source of exposure to ionizing radiation is therapeutic radiation for cancer or other proliferative diseases. Depending on the therapist's prescribed treatment procedure, the subject may receive multiple radiation doses over weeks to months.
[13] Therapeutic radiation is generally applied to a limited area of the body to be treated containing abnormally proliferating tissue to maximize the amount of radiation absorbed by the abnormal tissue and to minimize the amount of absorption into the surrounding normal tissue. However, it is difficult (but not impossible) to selectively administer therapeutic ionizing radiation to abnormal tissues. Thus, normal tissue adjacent to abnormal tissue is also exposed to potentially damaging ionizing radiation during treatment. In addition, some treatments expose the whole body of a subject to radiation in a procedure called “total body irradiation” or “TBI”. Thus, the efficiency of radiotherapy techniques for destroying abnormal proliferative cells should be balanced with the associated cytotoxicity of surrounding normal cells. Because of this, radiotherapy techniques have an inherently narrow therapeutic index that results in insufficient results for most tumor treatments. Even the best radiotherapy techniques can result in incomplete tumor reduction, tumor recurrence, increased tumor abundance and radiation-induced tumors.
[14] While applying an effective therapeutic amount of ionizing radiation, various methods have been developed to reduce damage to normal tissues. These techniques include brachytherapy, fractionated and hyperfractionated dosing, complex dose scheduling and high voltage therapy with delivery systems and linear accelerators. However, this technique is merely an attempt to attack the balance between the therapeutic and undesirable effects of radiation, and full efficacy has not been achieved.
[15] For example, treatment of treated subjects with metastatic tumors includes collecting their hematopoietic stem cells and then treating the treated subject with an excess of ionizing radiation. Such treatments are designed to destroy tumor cells of treatment, but also have the side effect of destroying their normal hematopoietic cells. Therefore, some of the bone marrow (containing hematopoietic stem cells) to be treated is removed before radiation treatment. After treatment of the subject, autologous hematopoietic stem cells are reintroduced into the body of the subject.
[16] However, if tumor cells metastasize away from the primary site of the tumor, some tumor cells may contaminate the collected hematopoietic cell population. In addition, if the subject to be treated has bone marrow cancer such as acute myeloid leukemia (AML), chronic myeloid leukemia (CML) or various FAB (French-American-British) subtypes of acute lymphocytic leukemia (ALL), the collected hematopoietic cell populations may also be And neoplastic cells. Therefore, metastatic tumor cells or endogenous tumor cells must be removed or killed before reintroducing stem cells to the subject. If any, tumor-derived cells or neoplastic cells are reintroduced to the subject, they can induce relapse.
[17] Conventional methods for removing tumor-derived or tumor-derived cells from harvested bone marrow are known as isolation of tumor cells from a total population or It is based on a killing strategy, which generally does not kill or eliminate all contaminated malignant cells. Such methods include leukopenia of fluent peripheral blood cells, immunoaffinity-based selection or death of tumor cells, or the use of cytotoxic or photosensitizing agents to selectively destroy tumor cells. In the best case, the malignant cell load may be between 1 and 10 tumor cells per 100,000 cells present at initial collection (Lazarus et al., J. Hematotherapy, 2 (4): 457-66, 1993). .
[18] Accordingly, there is a need for a purging method designed to selectively destroy malignant cells present in the bone marrow and to preserve normal hematopoietic stem cells necessary for hematopoietic regeneration in the transplantation subject.
[19] Exposure to ionizing radiation can also occur in occupational settings. Occupational doses of ionizing radiation may be received by persons whose occupation is, for example, a person who is exposed (or potential exposure) to radiation in the nuclear or nuclear weapons industry. Military personnel residing on ships powered by nuclear reactors or soldiers requiring work in areas contaminated with radioactive fallout are at similar risk to exposure to ionizing radiation. Occupational exposure may also occur in rescue and emergency personnel associated with major accidents involving nuclear reactors or radioactive material. Other causes of occupational exposure may be solvent, smoke alarms, emergency signs and other consumer products remaining in the manufacture of mechanical parts, plastics and radioactive medical products. Occupational exposures can also occur in people working on nuclear ships, especially those working in areas contaminated by nuclear radiation fallout, who deal with nuclear reactors, and rescue workers handling nuclear accidents.
[20] Environmental exposure to ionizing radiation may also be caused by nuclear explosions (experimental or at war), nuclear waste storage and treatment, release of actinide from nuclear fuel reprocessing, and naturally occurring radioactive materials such as radon gas or uranium. May be caused. The use of munitions containing depleted uranium also contaminates war zones with low-level radioactive contaminants.
[21] Radiation exposure from any cause can be classified as either acute (one mass exposure) or chronic (a small amount of low-level continuous or continuous low-level exposure spreading over time). . Radiation diseases generally result from acute exposure to significant doses of radiation and exhibit symptomatic manifestations in a series of forms including hair loss, weakness, vomiting, diarrhea, burns and bleeding in the gastrointestinal and mucous membranes. Genetic defects, infertility and cancer (especially bone marrow cancer) often appear over time. Frequent exposure is associated with delayed care issues such as cancer and premature aging. Acute systemic exposure of 125,000 millimetres can cause radiation sickness. Local radiation doses, as used for radiation therapy, do not cause radiation disease, but the exposed normal cells can be damaged or necrotic.
[22] For example, acute systemic radiation doses of 100,000-125,000 millimetres (equivalent to 1 Gy) received within one week result in significant physical effects such as burns or rashes, mucus and GI bleeding, nausea, diarrhea and / or fatigue. Long-term cytotoxicity such as hematopoietic and immune power cell destruction, hair loss (toxicosis), gastrointestinal and oral mucus escape, liver vein occlusion disease, and chronic vascular hyperplasia of cerebrovascular vessels, cataracts, pneumonia, skin changes and increased cancer and Genetic action may also appear over time. It can usually be caused by prolonged cytotoxicity or genetic action, but acute radiation doses below 10,000 millimetres (equivalent to 0.1 Gy) will not immediately produce significant physiological or physical consequences.
[23] A significant amount of acute radiation dose of ionizing radiation, for example, 500,000-1 million millimetres (equivalent to 5-10Gy) can kill a subject immediately. Millions of millimeters of radiation can die within 7 to 21 days in what is called "acute radiation poisoning." Reportedly, some Chernobyl firefighters died of acute radiation poisoning due to significant radiation in the range of 200,000 to 600,000 millimetres (equivalent to 2-6 Gy). Acute radiation doses below about 200,000 millimetres do not die, but exposed subjects suffer from prolonged cytotoxicity or genetic effects as described above.
[24] Occupational acute exposures usually occur to nuclear site workers and nuclear reactors exposed to radiation spills or fires, or to rescue workers for large accidents involving nuclear reactors or other sources of radioactive material. Limits presented by occupational acute exposure in emergencies are described by Brookhaven National Laboratories and are shown in Table 1.
[25] [Table 1] Occupational Acute Exposure Limits for Emergency Tasks
[26] Telegraphic conditions for radiation dose limits Required activity Exposure conditions 10,000 millimeters Need protection Voluntary, not substantial, low radiation dose 25,000 millimeters Life Saving: General Public Protection Voluntary, not substantial, low radiation dose > 25,000 millimetres Lifesaving work: many residents protection The risk is evident with any, not substantial, low radiation dose.
[27] 100,000 millimeters is equivalent to 1 Sv (sievert). For penetrating radiation such as gamma radiation, 1Sv corresponds to about 1Gy (Gray). Therefore, the radiation dose expressed in Gy can be estimated to be 1Gy per 100,000 millimetres.
[28] Chronic radiation dose is an incremental or continuous dose at low levels (ie 100-5000 millimeters) over time. Examples of chronic radiation doses include systemic radiation doses of ~ 5000 millimetres per year, which are typically given to adults working at nuclear sites. In contrast, the Atomic Energy Commission recommends that ordinary citizens not receive more than 100 millimeters per year. Chronic radiation doses can cause long-term cytotoxicity and gene action, for example, increasing the risk of radiation-induced cancers occurring in old age. Recommended limits for chronic exposure to ionizing radiation are given in Table 2.

[32] In comparison, Table 3 shows the radiation dose from common sources.

[35] Chronic doses above 5000 millimetres per year (0.05 Gy per year) may cause long-term cytotoxicity or gene action similar to that of humans exposed to acute radiation doses. In addition, some cytotoxic or genetic adverse effects may occur upon significant doses of chronic radiation of less than 5000 millimeters per year. For radiation protection purposes, any dose above zero can increase the risk of radiation-induced cancer (ie, there is no limit). Epidemiological studies have found that the lifetime risk of dying from cancer is about 0.04% or more per 1 rem of systemic radiation.
[36] Although anti-radiation is suitable or other protective devices may be effective in reducing radiation exposure, these tools are very expensive, not universal, and not available to the public. In addition, the radiation protection tool cannot protect normal tissue adjacent to the tumor from missed radiation exposure during radiation treatment. Thus, there is a need for a practical method of protecting an object that is planned to be exposed to, or facing exposure to, ionizing radiation. With regard to therapeutic radiation, it is desirable to enhance the protection of normal cells while the tumor cells remain vulnerable to the harmful effects of radiation. Thus, it is desirable to provide systemic protection from anticipated or accidental systemic radiation that may occur with occupational or environmental exposure or with respect to particular treatment techniques.
[37] Pharmaceutical radioprotectants are cost-effective and effective and readily available as compared to radiation protection tools. However, radiation protection of normal cells using conventionally tried pharmaceutical compositions has not been completely successful. For example, cytokines, which directly fluidize peripheral blood reproductive cells, act as bone marrow protective agents when given before irradiation (Neta et al., Semin. Radiat. Oncol. 6: 306-320, 1996). No protection is provided. Other chemoprotectants, administered alone or in combination with physiological response modifiers, show very little protective effect in rats, but the application of these compounds to large mammals has not been successful, and chemoradioprotection has some value. It was questioned whether or not it had (Maisin, JR, Bacq and Alexander Award Lecture. "Chemical radioprotection: past, present, and future prospects", Int J. Radiat Biol. 73: 443-50 , 1998). Pharmaceutical radiation sensitizers known to preferentially enhance the effect of radiation in cancerous tissues are not suitable for general tissue protection of normal tissues exposed to ionizing radiation.
[38] There is a need for a therapeutic agent for the treatment of exposure to or at risk of ionizing radiation. In therapeutic radiation environments, it is desirable to enhance the protection of normal cells and to maintain tumor cells vulnerable to the deleterious effects of radiation. Furthermore, systematic protection from anticipated or accidental systemic radiation that may occur in connection with occupational or environmental exposure or specific treatment techniques is required.
[2] The present invention is not limited thereto, but relates to compositions and methods for treating proliferative diseases, including cancer. The present invention is directed to protecting normal cells and tissues from expected, planned or accidental exposure to ionizing radiation.

Arylethene sulfonyl chloride is highly reactive with N-aryl compound C and HCl is a reaction byproduct. The base is present in the solvent and acts as a scavenger of the resulting HCl. Such compounds may serve as both aprotic solvents and bases. Such dual-function solvents include, for example, pyridine, substituted pyridine, trimethylamine and triethylamine.

[165] Synthesis 1: Synthesis of Olefin Sulfonyl Chloride and Reaction with Arylamine to Form Compound of Formula (I)
[166] According to Synthesis 2, a condensation of the Knoevenagel-type according to Synthesis 321-322 (1975, 5) by Oliver et al., According to the condensation of arylaminosulfonylacetic acid intermediate G with a suitable aryl aldehyde H, is used. The disclosure of Oliver et al. Is incorporated herein by reference.
[167] Synthesis 2: Synthesis of Compound of Formula (I)
[168]
[169] Methyl (or ethyl) β-chlorosulfonyl acetate intermediate E is prepared from methyl (or ethyl) bromoacetate (R '= methyl or ethyl). Thus, methyl (or ethyl) bromoacetate reacts with sodium sulfate to form sodium sulfoacetate intermediate Na ₂ OSO ₂ CH ₂ CO ₂ R '. Potassium sulfate can be used as an alternative to sodium sulfate. The sodium sulfoacetate intermediate is then reacted with a chlorinating agent, preferably PCl ₅ to form methyl (or ethyl) β-chlorosulfonylacetate intermediate E. The reaction of intermediate E with aromatic amine C yields arylaminosulfonyl acetate intermediate F. The latter reaction is carried out in an aprotic solvent in which the base is present. The same compound can serve as both a nonprotic solvent and a base. Such dual-function solvents include, for example, pyridine, substituted pyridine, trimethylamine and triethylamine. The arylaminosulfonylacetate F is then converted to the corresponding arylaminosulfonylacetic acid compound G by any base capable of hydrolyzing the ester action of F to an acid. Such bases include, for example, KOH and NaOH. In the final step, the arylaminosulfonylacetic acid compound is condensed with arylaldehyde H by Knoevenagel reaction and decarboxylation of the intermediate in the presence of a basic catalyst. Basic catalysts include, for example, pyridine and benzylamine. This reaction gives the desired N- (aryl) -2-arylethenesulfonamide of formula (I).
[170] Hereinafter, the method for preparing the compound of formula (I) according to Synthesis 1 (General Method 1) or Synthesis 2 (General Method 2) will be described in more detail.
[171] Common way 1
[172] A. (E) -Q ₂-CH = CH-SO ₂Synthesis of Cl
[173] To a stirred solution of arylethene A (0.1 mol) in dimethyl formamide (30 mL) was added dropwise sulfuryl chloride (0.2 mol) over 30 minutes under nitrogen atmosphere. After the addition is complete, the solution is further stirred under nitrogen atmosphere for 5 hours. The reaction mixture is then poured slowly into cold water (250 mL) and the precipitate is extracted with diethyl ether. Evaporation of the dried ether layer gives the corresponding sulfonyl chloride (E) -Q ₂ -CH = CH-SO ₂ Cl (B).
[174] B. Using Arylamines(E) -Q ₂-CH = CH-SO ₂Condensation of Cl
[175] N-aryl compound C (10 mmol) and sulfonyl chloride B (10 mmol) are dissolved in 15 ml of pyridine under nitrogen. The mixture is stirred at room temperature for 6 hours and the solvent is removed at inhaler pressure. Water (100 mL) is added to the residue and the product is filtered off. Recrystallization of the product affords pure N- (aryl) -2-arylethenesulfonamide of formula (I).
[176] Common method 2
[177] A. Synthesis of Sodium Ethyl or Methyl Sulfoacetate
[178] A solution of ethyl or methyl bromoacetate (0.1 mol) dissolved in ethanol (50 mL) is added dropwise to a stirred cold solution of sodium sulfite (0.1 mol) dissolved in water (100 mL). After complete addition, the mixture is briefly heated to 50 ° C. and then concentrated to dryness. The solid residue is extracted with boiling 2: 1 acetic acid / ethyl acetate (200 mL) and the hot solution is filtered and cooled overnight. Sodium methyl or ethyl sulfoacetate obtained as a white solid is collected by filtration.
[179] B. Synthesis of Ethyl or Methyl Arylaminosulfonyl Acetate
[180] Sodium methyl or ethyl sulfoacetate (0.1 mol) and phosphorus (V) (0.11 mol) are ground, respectively, and then combined in a flask equipped with a condenser and a drying tube. After a few minutes of mixing, an exothermic reaction occurs. After the reaction has subsided, the flask is warmed in a steam bath for 1 hour and then phosphoryl chloride is removed in vacuo. The benzene fraction is added and the resulting solution is filtered and evaporated to give an ethyl or methyl chlorosulfonyl acetate (E) solution. Benzene (50 mL) is added to the clear oil and the solution is stirred and cooled. To the solution was added dropwise triethylamine (10 mL) dissolved in N-aryl compound C and benzene (50 mL). After complete addition, the mixture is warmed for 5 minutes, then cooled and filtered. The filtrate is washed with water, dilute hydrochloric acid, aqueous sodium hydrogen carbonate and aqueous sodium chloride. After drying, the solvent is removed to give crude ethyl or methyl arylaminosulfonyl acetate F. Recrystallization from benzene gives pure compounds.
[181] C. Synthesis of Arylaminosulfonyl Acetic Acid
[182] Ethyl or methyl arylaminosulfonyl acetate F (0.1 mol) was refluxed for 2.5 hours in a solution of potassium hydroxide (15 g) dissolved in water (100 mL) and ethanol (40 mL). Charcoal is added and the solution is heated to boiling for 5 minutes, filtered, acidified with hydrochloric acid and extracted with ether. The ether extract is washed with water, dried and evaporated to give crude arylaminosulfonylacetic acid G, which is purified by recrystallization with benzene.
[183] D. Condensation of Arylaminosulfonyl Acetic Acid with Arylaldehyde
[184] A solution of arylaminosulfonylacetic acid G (10 mmol), arylaldehyde H (10 mmol), pyridine (1 mL) and ammonium acetate (250 mg) was refluxed in toluene for 22 hours with azeotropic removal of water. The solution is cooled and washed with water, dilute hydrochloric acid and aqueous sodium hydrogen carbonate and then extracted with 10% potassium hydroxide. The two-phase aqueous extract is washed with ether and acidified with hydrochloric acid. The ether extract is evaporated to afford crude N- (aryl) -2-arylethenesulfonamide of formula (I). Recrystallization with a suitable solvent gives an analytical sample.
[185] Aryl center of Q ₁ is a group (Wherein X is sulfur or oxygen, and R ⁵ and R ⁶ are as defined above). N- (aryl) -2-arylethenesulfonamides of the general formula (I) are prepared as a variant of the process. Thus, aryl intermediates substituted with at least one amino and at least one nitro group, preferably with a phenyl intermediate of formula III

[196]
[197] The reaction can be carried out, for example, by dissolving a compound of formula VI in deionized water and adding approximately the same molar amount to intermediates V or Va dissolved in a suitable solvent, such as glacial acetic acid. The reaction mixture is stirred for 3 hours at room temperature. The reaction mixture is then poured into deionized water and extracted three times with ethyl acetate. The resulting combined organic layer is washed with saturated NaHCO ₃ and brine. The solvent is dried over MgSO ₄ , filtered and concentrated under reduced pressure. The resulting solid is, for example, recrystallized from hot ethyl acetate / hexanes to give sulfonamide VII.
[198] The compounds of the present invention can be used in this form or as pharmaceutically acceptable salts. The term "pharmaceutical acceptable salt" includes salts commonly used to prepare alkali metal salts and addition salts of free acids or free bases. The nature of such salts is not critical to the pharmaceutically acceptable. Suitable pharmaceutically acceptable acid addition salts can be prepared from inorganic or organic acids. Examples of such inorganic acids are hydrochloric acid, hydrobromic acid, hydroiodic acid, nitric acid, carbonic acid, sulfuric acid and phosphoric acid. Suitable organic acids can be selected from sulfonics of aliphatic, cycloaliphatic, aromatic, arylphatic, heterocyclic, carboxylic and organic acids, examples of which are formic acid, acetic acid, propionic acid, succinic acid, glycolic acid, glyconic acid , Lactic acid, malic acid, tartaric acid, citric acid, ascorbic acid, glucuronic acid, maleic acid, fumaric acid, pyruvic acid, aspartic acid, glutamic acid, benzoic acid, anthranilic acid, mesylic acid, salicylic acid, 4-hydroxybenzoic acid, phenylacetic acid, mandelic acid , Embonic (pamoic) acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, pantothenic acid, 2-hydroxyethanesulfonic acid, toluenesulfonic acid, sulfanilic acid, cyclohexylaminosulfonic acid, stearic acid, alzenic acid, beta -Hydroxybutyric acid, salicylic acid, galactaric acid and galacturonic acid. Suitable pharmaceutically acceptable base addition salts of compounds of formula (I) include metal salts of calcium, magnesium, potassium, sodium and zinc, or N, N'-dibenzylethylenediamine, chloroprocaine, chlorine, diethanolamine, ethylenediamine Organic salts of meglumine (N-methylglucamine) and procaine. All such salts can be prepared by conventional means from, for example, the corresponding compounds of formula (I) by reacting a suitable acid or base with formula (I).
[199] The compounds of the present invention can be administered to individuals suffering from cancer (mammals, including animals and humans).
[200] The compounds are also useful for the treatment of non-cancer proliferative diseases, i.e. proliferative diseases that are shown to be positive. This disease is also known as "cytoproliferative" or hyperproliferative, because cells show abnormal growth rates in the body, such as but not limited to neonatal angiomatosis. , Secondary progressive multiple sclerosis, chronic progressive myelodegenerative disease, neurofibromatosis, ganglioneuromatosis, keloid formation, Pagets Disease of the bone , Fibrocystic disease of the breast, Peronies and Duputren's fibrosis, restenosis, and cirrhosis.
[201] Of course, in the treatment of proliferative diseases, the specific dosage of a compound according to the invention for obtaining a therapeutic effect may be determined by each patient including the size, weight, age and sex of the patient, the nature and stage of the disease, the aggressiveness of the disease and the route of administration. It will depend on your particular situation. For example, a daily dose may be used at about 0.05-50 mg / kg / day. More or less dosages may also be intended.
[202] Of course, the specific dosages and schedules of N- (aryl) -2-arylethenesulfonamide to achieve the radioprotective effect depend on the size, weight, age and sex of the patient, the nature and stage of the disease to be treated, the aggressiveness of the disease, It will be determined according to the particular route of each patient including the route of administration and the toxicity of the particular radiation. For example, the daily dose may be used at about 0.01-150 mg / kg / day, more preferably at about 0.05-50 mg / kg / day. Particularly preferred is a dose of about 1.0-10.0 mg / kg / day, for example 7.0 mg / kg / day. The dosage may be administered multiple times, for example, twice as much as 3.5 mg / kg / day. Higher or lower doses are also contemplated.
[203] In radioprotective administration, the N- (aryl) -2-arylethenesulfonamide is applied before the radiation is applied so that the compound can reach a sufficient concentration in the normal cells of the treatment to have a radioprotective effect on the normal cells. Should be administered well ahead of time. The compound may be administered about 24 hours before the radiation, preferably not more than about 18 hours. In one embodiment, the N- (aryl) -2-arylethenesulfonamide is administered at least about 6-12 hours prior to administering the therapeutic radiation. Most preferably, the compound is administered again about 18 hours and about 6 hours before exposure to radiation. One or more N- (aryl) -2-arylethenesulfonamides may be administered simultaneously or other N- (aryl) -2-arylethenesulfonamides may be administered at different times during treatment.
[204] When the therapeutic radiation is administered continuously, it is desirable to include the administration of one or more N- (aryl) -2-arylethenesulfonamides in the schedule of radiation therapy. As noted above, different N- (aryl) -2-arylethenesulfonamides may be administered simultaneously or at different times during treatment. Preferably, the period of about 24 hours separates administration of the radioprotective compound and the therapeutic radiation. More preferably, the radioprotective N- (aryl) -2-arylethenesulfonamide and therapeutic radiation are separated by about 6-18 hours. This strategy will significantly reduce side effects due to radiation without affecting the anticancer activity of the therapeutic radiation.
[205] For example, the treatment radiation can be irradiated for five consecutive days at a dose of 0.1 Gy daily, taking two days off for a total of six to eight weeks. One or more N- (aryl) -2-arylethenesulfonamides may be administered to the subject 18 hours before each repetition of radiation. However, due to the normal cell protection provided by N- (aryl) -2-arylethenesulfonamide, more aggressive treatment schedules, ie higher radiation doses, are contemplated in accordance with the present invention. Accordingly, the radioprotective effect of the compound increases the therapeutic index of the therapeutic radiation and allows the therapist to safely increase the radiation dose of the therapeutic radiation above the currently recommended level without the risk of increasing damage to surrounding normal cells and tissues. .
[206] Furthermore, the N- (aryl) -2-arylethenesulfonamide of the present invention protects normal bone marrow cells from radiation therapy designed to destroy hematologic neoplastic cells or tumor cells that have spread to the bone marrow. useful. Such cells include, for example, myeloid leukemia cells. The appearance of these cells in the bone marrow and other parts of the body is associated with various disease conditions, such as the FAB (French-American-British) subtype of acute myeloid leukemia (AML), chronic myelogenous leukemia (CML) or acute lymphocytic leukemia (ALL) do. In particular, CML is responsible for the abnormal proliferation of immature granular leukocytes (eg, neutrophils, eosinophils and basophils) in blood vessels, bone marrow, spleen, liver, and other tissues Accumulation of granular leukocyte precursors in tissues. Treatments exhibiting these symptoms typically have at least 20,000 leukocytes per microliter of blood, and this number may exceed 400,000. Indeed, all CML patients will have a "blast crisis", and by the end of the disease, immature blast cells will rapidly proliferate and lead to death.
[207] Other subjects suffer from metastatic tumors and require systemic radiation (TBI) treatment. In addition, TBI will necrotic the hematopoietic cells to be treated, so that a portion of the bone marrow to be treated is removed before irradiation for subsequent replanting. However, metastatic tumor cells are present in the bone marrow, and replanting often leads to cancer recurrence in a short time.
[208] Subjects with myeloid neoplastic disease or metastatic neoplasia remove part of the bone marrow (also called "collection"). The harvested bone marrow of malignant stem cells can be purged and the purged bone marrow can be transplanted and treated. Preferably, the subject may receive radiation or some other chemotherapy before replanting the self-purged bone marrow.
[209] Accordingly, the present invention provides a method of removing bone marrow from a subject, administering an effective amount of at least one N- (aryl) -2-arylethenesulfonamide, and treating the bone marrow with necrotic cells in the bone marrow. Provided are methods for reducing the number of malignant cells in bone marrow comprising irradiating a sufficient dose of ionizing radiation. As used herein, the term "malignant cell" refers to any cell that proliferates uncontrolled, such as a tumor cell or a neoplastic cell. The N- (aryl) -2-arylethenesulfonamide protects normal hematopoietic cells present in the bone marrow from the deleterious effects of ionizing radiation. In addition, the N- (aryl) -2-arylethenesulfonamide exhibits direct necrosis on malignant cells. The number of malignant cells in the bone marrow is significantly reduced before replanting, thereby minimizing relapse.
[210] Preferably, each N- (aryl) -2-arylethenesulfonamide is about 0.25-100 micromolar; More preferably about 1.0 to 50 micromoles; In particular, it is administered at a concentration of about 2.0-25 micromolar. Particularly preferred concentrations are 0.5, 1.0 and 2.5 micromolar and 5, 10 and 20 micromolar. Higher or lower concentrations may also be used.
[211] The N- (aryl) -2-arylethenesulfonamide can be added directly to the collected bone marrow but is preferably dissolved in an organic solvent such as dimethyl sulfoxide (DMSO). Pharmaceutical combinations of N- (aryl) -2-arylethenesulfonamides as described in more detail below may also be used.
[212] Preferably, said N- (aryl) -2-arylethenesulfonamide is added to the collected bone marrow about 20 hours before exposure to radiation, preferably not more than about 24 hours. In one embodiment, the N- (aryl) -2-arylethenesulfonamide is administered to the bone marrow collected at least about 6 hours prior to exposure to radiation. One or more N- (aryl) -2-arylethenesulfonamides may be administered simultaneously or other N- (aryl) -2-arylethenesulfonamides may be administered at different times. Other dosage regimens are also intended.
[213] If the subject is treated with ionizing radiation prior to the transplantation of purged bone marrow, the subject may be treated with one or more N- (aryl) -2-arylethenesulfonamides prior to irradiation with ionizing radiation as described above. have.
[214] In addition, as described in the background, the subject may be exposed to ionizing radiation for occupational or environmental reasons. For the purposes of the present invention, the radiation source is not as important as the type (ie acute or chronic) and the level of radiation absorbed by the subject being treated. It is understood that the following descriptions include cases of exposure to ionizing radiation due to both occupational and environmental causes.
[215] Therapies that suffer from the effects of acute or chronic exposure to ionizing radiation, not just fatal, are said to have undergone curable radiation damage. Such treatable radiation damage can be reduced or eliminated with the compounds and methods of the present invention.
[216] Acute radiation doses of ionizing radiation that can cause curable radiation damage are, for example, about 10,000 millimeters (0.1 Gy) to 1,000,000 millimeters (10 Gy) within 24 hours, preferably about 25,000 within 24 hours. Millimeters (0.25 Gy) to 200,000 millimeters (2 Gy) and more preferably, local or systemic radiation doses of about 100,000 millimeters (1 Gy) to 150,000 millimeters (1.5 Gy) within 24 hours.
[217] Chronic radiation doses of ionizing radiation that can cause therapeutic radiation damage range from about 100 millimeters (0.001 Gy) to 10,000 millimeters (0.1 Gy), preferably about 1000 millimeters, over a period of 24 hours or more. 0.01 Gy) to 5000 milliliters (0.05 Gy) of total radiation dose or from 15,000 millimeters (0.15 Gy) to 50,000 millimeters (0.5 Gy) over a 24 hour period.
[218] Accordingly, the present invention is directed to ionizing radiation comprising administering an effective amount of at least one radiation protective N- (aryl) -2-arylethenesulfonamide to reduce or eliminate the cytotoxic effects of radiation exposure on normal cells and tissues. Provided are methods for treating a subject with curable radiation damage caused by acute or chronic exposure to the subject. The compound is preferably administered within the shortest possible time after exposure to radiation, for example within 0-6 hours after exposure.
[219] Treatable radiation damage can be in the form of cytotoxic and genotoxic (ie, genetically adversely affecting) treatments. In another embodiment, therefore, cytotoxicity of radiation exposure to normal cells and tissues by administering an effective amount of at least one radioprotective N- (aryl) -2-arylethenesulfonamide compound prior to exposure to acute or chronic radiation. Or to reduce or eliminate the effects of genotoxicity. The N- (aryl) -2-arylethenesulfonamide can be administered, for example, about 24 hours prior to exposure to radiation, preferably not more than about 18 hours prior to exposure to radiation. In one embodiment, the N- (aryl) -2-arylethenesulfonamide is administered at least about 6 hours prior to exposure to radiation. Most preferably, the N- (aryl) -2-arylethenesulfonamide is administered again about 18 hours and about 6 hours before exposure to radiation. One or more N- (aryl) -2-arylethenesulfonamides may be administered simultaneously, or other N- (aryl) -2-arylethenesulfonamides may be administered at different times.
[220] If multiple acute exposures are expected, the radioprotectant may be administered multiple times. For example, if fire or rescue personnel have to enter the contaminated area several times, N- (aryl) -2-arylethenesulfonamide may be administered prior to each exposure. Preferably, administration of the compound and radiation exposure are separated for about 24 hours. More preferably, administration of N- (aryl) -2-arylethenesulfonamide and radiation exposure are separated for about 6-18 hours. In addition, workers of nuclear power plants are intended to administer an effective amount of N- (aryl) -2-arylethenesulfonamide prior to each shift to reduce or eliminate the effects of exposure to ionizing radiation.
[221] If exposure to the ionizing radiation of the subject is expected, N- (aryl) -2-arylethenesulfonamide may be administered periodically during the intended exposure period. For example, a nuclear worker or a soldier working in an area contaminated with radioactive fallout may be given a radioprotective compound every 24 hours, preferably every 6-18 hours, to mitigate the effects of radiation damage. . Likewise, N- (aryl) -2-arylethenesulfonamide compounds may be administered to civilians periodically until decontaminated civilian settlements contaminated with radiation fallout or until civilians are moved to safer locations. .
[222] As used herein, "administered" refers to the act of allowing a subject to utilize an N- (aryl) -2-arylethenesulfonamide compound so that a pharmacological effect can be obtained. The pharmacological effect on the administration of radioprotective drugs is evident from the absence of the physiological or clinical symptoms expected at specific levels of radiation exposure. Those skilled in the art can readily determine the presence or absence of radiation-induced effects through well-known experimental and clinical methods. Thus, the N- (aryl) -2-arylethenesulfonamide compound can be administered by any route sufficient to impart the desired radiation protective action to the patient.
[223] The N- (aryl) -2-arylethenesulfonamide compound may be effectively administered to the treatment by any route, such as, for example, the digestive tract (eg, oral, rectal, nasal, etc.) and parenteral administration. Parenteral administration includes, for example, intravenous, intramuscular, intraarterial, intraperitoneal, vaginal, intra bladder (eg, into the bladder), intradermal, topical or subcutaneous administration. . It is also intended to within the scope of the present invention to inject a medicament in a controlled formulation into the patient's body such that systemic or local release of the medicament occurs later. For example, an N- (aryl) -2-arylethenesulfonamide depot may be administered to a patient at least 24 hours prior to irradiation. Preferably, at least some of the compound is retained at the accumulation site and is not released until about 6-18 hours prior to exposure to radiation. For anticancer purposes, the medicament may likewise be located locally at the accumulation site so as to be controlled release from the area where the tumor grows during circulation.
[224] The compound of the present invention may be administered in the form of a pharmaceutical composition combined with a pharmaceutically acceptable carrier. The active ingredient in such a combination may comprise 0.1 to 99.99% by weight. "Pharmaceutically acceptable carrier" means any carrier, diluent or excipient that is miscible with the other ingredients of the formulation and that is not harmful to the recipient.

[275] Example 68: Effect of N- (aryl) -2-arylethenesulfonamide on tumor cell lines
[276] The effect of N- (aryl) -2-arylethenesulfonamide on normal fibroblasts and tumor cells was measured by the assay described in Oncogene 12: 827-837 (1996) by Latham et al. Normal diploid pulmonary human fibroblasts (HFL-1) or tumor cells (prostate, rectal colon, breast, glial, follicular, ovary or leukemia) are 6-well dishes with a cell density of 1.0x10 ⁵ cells per 35 mm2 well. incubated in (dish). Cultured cells were treated with various concentrations of N- (aryl) -2-arylethenesulfonamide dissolved in dimethyl sulfoxide (DMSO) after 24 hours. After 96 hours, the wells were trypsinized and the number of viable cells was counted to determine the total number of viable cells by trypan blue exclusion using a hemocytometer. Each compound tested (Examples 1-7) inhibited cell proliferation when tested at 30 micromolar concentrations. Some compounds inhibited proliferation at lower concentrations. Certain compounds necrosis cells at 1-10 micromolar concentrations. Normal HFL cells were treated with the same compound at the same concentration and time conditions. Normal cells showed growth inhibition, but no necrosis of the cells was detected.
[277] Example 69 GI ₅₀ Measurement
[278] A dose response curve for the tumor growth inhibitory effect of (E) -4-methoxystyryl-N-4-fluorophenyl sulfonamide on estrogen-unreacted breast cells was obtained (FIG. 1). GI ₅₀ (drug concentration showing a net growth inhibition of 50%) was measured at 10 μM. In contrast, normal fibroblast line HFL-1 exhibited a GI ₅₀ of ₅₀ μM. (E) -4-methoxystyryl-N-4-fluorophenyl sulfonamide GI ₅₀ for the same compound against the cell line shown in Table 7 was measured in the same manner.

[281] GI ₅₀ of (E) -4-methoxystyryl-N-3-fluoro-4-methoxyphenyl sulfonamide was measured for the following cell lines: BT20, DU145, H157 and DLD-1. The GI ₅₀ for each cell line was substantially in agreement with the GI ₅₀ measured for (E) -4-methoxystyryl-N-4-fluorophenyl sulfonamide in the same cell line.
[282] Example 70 Induction of Apoptosis in Tumor Cells
[283] The next assay is to demonstrate the apoptotic activity of the compounds according to the invention on tumor cells.
[284] Caspases and ICE-based proteases are cysteine proteases that are activated during apoptosis (Patel et al., FASEB 10: 587-597, 1996). Cleavage of poly (ADP-ribose) polymerase (PARP), which is the target of caspase 3, apopane and several other activated proteases, is widely used and recognized as a marker for apoptosis (Nicholson et al. Nature 376 (6533): 37-43, 1995; Lippke et al., J. Biol. Chemistry 271: 1825, 1996). In this assay, BT20 cells, estrogen receptor negative breast carcinoma, and HFL-1 cells, normal lung fibroblasts were (E) -4-methoxystyryl-N-4-fluorophenyl sulfone at 20 μM final concentration for 96 hours. Treated with amide or dimethyl sulfoxide (DMSO). The cells were then lysed in RIPA buffer and 100 μg of total cellular protein in each sample was lysed on 10% SDS-polyacrylamide gels. The protein was then allowed to Western blot on PROTRAN filter paper (S / S), after which the filter was probed with a specific antibody to PARP (Boehringer Manheim). The antibody recognizes both 116 kDa full length PARP and 83 kDa crack products. The results shown in FIG. 2 indicate that 96 hours of treatment with the test compound activates caspase, especially in treated breast carcinoma cell lines, but not in normal cell lines. The Westerm blot clearly indicated that 83 kDa PARP crack product was present only in BT20 cells treated with the test compound. HFL-1 cells treated in the same manner did not show full length PARP cracks. BT20 cells treated with DMSO for the same time did not have activity of the apoptosis pathway. These results indicate that the compounds of the present invention exhibit cysteine protease activity, a molecular marker for apoptosis, thereby selectively killing cancer cells by activation of the apoptosis pathway. Cells that are not tumorigenic are not apoptotic but growth is inhibited at concentrations significantly higher than those required for tumor cell death.
[285] Example 71: Radioprotective Action of N-aryl-2-arylethenesulfonamide on Cultured Normal Cells
[286] (A) styryl-N-phenylsulfonamide for cultured normal cells, (b) 4-methoxystyryl-N-fluorophenylsulfonamide; The radiation protection of (c) styryl-N-methyl-N-phenyl-sulfonamide and (d) 4-methoxystyryl-N-2,4,6-trimethoxyphenylsulfonamide was evaluated as follows. It was.
[287] Normal diploid lung fibroblasts, HFL-1, were cultured in 24-well dishes at a cell density of 3000 cells per 10 mm 2 in DMEM filled with 10% fetal bovine serum and antibiotics. The test compounds were added to the cells using DMSO as solvent after 24 hours at specific concentrations from 2.5 μM to 10.0 μM (including these). Standard cells were treated with DMSO only. Cells were exposed to test compound or DMSO for 24 hours.
[288] The cells were then irradiated with 10 Gy (gray) ionizing radiation (IR) using a JL Shepherd Mark I, Model 30-1 irradiator equipped with ¹³⁷ cesium as a source. After irradiation, test and normative cell media were removed and replaced with new growth media without test compound or DMSO. The irradiated cells were incubated for 96 hours, after which the pair of wells were trypsinized and replanted onto 100 mm 2 tissue culture dishes. The replanted cells were exchanged only once with fresh medium and grown for two weeks at standard conditions. In each 100 mm 2 culture dish, the number of colonies representing the number of viable cells was measured by staining the dishes as described below.
[289] To visualize and count colonies derived from clonal growth of individual protected cells, the medium was removed and the plates were washed once with phosphate buffer silane at room temperature. The cells were stained with Modified Geimsa staining solution (Sigma) diluted 1:10 for 20 minutes. The colorant was removed and the plate was washed with tap water. Plates were air dried, colonies counted on each plate and averaged over a pair of plates. At the concentrations tested, each compound was given 4- to 6-fold radioprotective activity. Fold protection was determined by dividing the average number of colonies on the test plate by the average number of colonies counted on the norm plate.
[290] Example 72: Protection of Rats from Radiation Toxicity Pretreated with N-aryl-2-arylethenesulfonamide
[291] 10-12 week old C57 black rats (Taconic) were divided into 10 rats each and treated with 200mg of N-aryl-2-arylethenesulfonamide dissolved in DMSO (10mg / Kg based on 20g mice). Peritoneal injection). Injections were made 18 and 6 hours prior to irradiation with 8 Gy gamma radiation. Ten normative groups treated only 8Gy gamma radiation. Mortality of the norm and test group was assessed for 40 days after irradiation.
[292] Example 73: Radiation Protective Effect of N-aryl-2-arylethenesulfonamide on Mice when Treated After Radiation Exposure
[293] C57 black rats (Taconic) 10-12 weeks old were divided into treatment groups and norm groups, respectively. After 15 minutes of 8 Gy gamma irradiation to each treatment group, 200 μg (10 mg / Kg dose based on 20 g of rat) dissolved in DMSO was injected intraperitoneally. . The norm group treated only 8 Gy gamma radiation. Mortality of the norm and test group was assessed for 40 days after irradiation.
[294] Example 74: Exposure Effect of Ionizing Radiation to Normal and Malignant Hematopoietic Progenitor Cell Growth After Pretreatment with N-aryl-2-arylethenesulfonamide
[295] The effect of ionizing radiation on normal and malignant hematopoietic progenitor cells pretreated with N-aryl-2-arylethenesulfonamide was measured by assessing the cloning efficiency and incidence of pretreated cells after irradiation.
[296] To obtain hematopoietic progenitor cells, human bone marrow cells (BMCs) or peripheral blood cells (PBs) were obtained from normal healthy volunteers or from acute myelogenous leukemia or chronic myeloid leukemia (AML, CML) volunteers by Ficoll-Hypaque descent centrifugation. Hematopoietic progenitor cells were partially enriched by positively selecting CD34 ⁺ cells with immunomagnetic beads (Dynal AS, Oslo, Norway). CD34 ⁺ cells were suspended in supplemental alpha medium and gently inverted the tube and incubated with murine anti-HPCA-I antibody diluted 1:20 at 4 ° C. for 45 min. The cells were washed three times with supplemental alpha medium and then incubated with beads coated with Fc segments of goat anti-mouse IgG ₁ (75 μl of immunobead / 10 ⁷ CD34 ⁺ cells). After 45 minutes of incubation (4 ° C.), the attachment of cells to the beads is positively selected using a magnetic particle concentrator according to the manufacturer's instructions.
[297] 2 × 10 ⁴ CD34 ⁺ cells were cultured in 0.4 ml of Iscove's modified Dulbecco's medium (IMDM) in total volume containing 2% human AB serum and 10 mM Hepes buffer in 5 ml polypropylene tubes (Fisher Scientific, Pittsburgh, Pa.). For example, three different concentrations (2.5 μM, 5.0 μM and 10.0 μM) of N-aryl-2-arylethenesulfonamide dissolved in DMSO, such as styryl-N-phenylsulfonamide; 4-methoxystyryl-N-fluorophenylsulfonamide; Styryl-N-methyl-N-phenylsulfonamide; Or 4-methoxystyryl-N-2,4,6-trimethoxyphenylsulfonamide was added to the cells, respectively. Only DMSO was added to the cells. The cells were incubated for 20-24 hours and irradiated with 5Gy or 10Gy of ionizing radiation. Immediately after irradiation, the medium was removed and replaced with fresh medium without test compound or DMSO. Twenty four hours after irradiation, the treated and normative cells were prepared for plating on plasma clots or methylcellulose cultures. Cells (1 × 10 ⁴ CD34 ⁺ cells per dish) were not washed before plating.
[298] Cloning efficiency and development of treated hematopoietic progenitor cells were assessed as described in Gewirtz et al., Science 242, 1303-1306 (1988), incorporated herein by reference.
[299] Example 75 Bone Marrow Purge Using Ionizing Radiation After Pretreatment with N-aryl-2-arylethenesulfonamide
[300] The standard technique is to collect bone marrow from the long bone of the subject under general anesthesia in the operating room. Inhale several times with a heparin-added syringe. The therapeutic target is to collect the bone marrow to make enough to receive a bone marrow cell processing of approximately 4x10 ⁸ ~8x10 ⁸ weight per 1kg. Thus, about 750-1000 ml of bone marrow is collected. Inhaled bone marrow is immediately transferred to transfer media (TC-199, Gibco, Grand Island, New York) containing 10,000 units of heparin free of preservatives per 100 ml of medium. Inhaled bone marrow is filtered through three progressively finer meshes to obtain cellular suspension free of cellular aggregates, debris and bone particles. The filtered bone marrow is then further processed with an automated cell separator (eg, Cobe 2991 Cell Processor) to produce a "buffy coat" product (ie, red blood cells and platelet free leukocytes). The leukocyte soft layer preparation is then placed in a shipping pack for subsequent processing and storage. Can be stored until purged with liquid nitrogen by standard methods. Purging can also be done immediately, after which the purged bone marrow can be frozen in liquefied nitrogen until transplanted.
[301] The purge procedure is performed as follows. In leukocyte softener preparations, cells are adjusted to a cell concentration of about 2 × 10 ⁷ / ml in TC-199 containing about 20% autologous plasma. N-aryl-2-arylethenesulfonamide; For example, 2.5-10 micromolar styryl-N-phenylsulfonamide dissolved in DMSO; 4-methoxystyryl-N-fluorophenylsulfonamide; Styryl-N-methyl-N-phenylsulfonamide; Alternatively, 4-methoxystyryl-N-2,4,6-trimethoxyphenylsulfonamide is placed in a transport pack containing cell suspension and incubated in a 37 ° C. bath for 20-24 hours with gentle shaking. The shipping pack is then exposed to 5-10 Gy ionizing radiation. Recombinant human hematopoietic growth factors, such as rH IL-3 or GM-CSF, may be added to the suspension to stimulate hematopoietic neoplastic growth and thus increase their sensitivity to ionizing radiation.
[302] The cells can then be frozen in liquid nitrogen or washed once at 4 ° C. with TC-199 containing about 20% autologous plasma. The washed cells are then injected into the treatment. Care should be taken at all times to work under possible sterilization conditions and to maintain sterile technique.

[131] The term "treatment (or subject)" or "individual" includes humans and non-human animals. In the above methods of radioprotection, furthermore, these terms refer to organisms in the situation or exposed to which exposure to ionizing radiation is intended.
[132] As used herein, the term “ionizing radiation” when absorbed by cells and tissues is radiation of sufficient energy to induce the formation of reactive oxygen species and DNA damage. This type of radiation includes X-rays, gamma rays, and particle bombardment (eg, neutron beams, electron beams, protons, mesons, etc.), and include medical test and treatment, scientific purposes, industrial testing, manufacturing and disinfection, It is used for weapons and weapons development and various other uses. In general, radiation is measured in units of absorbed radiation dose such as rad or gray or Gy, or in units of the same dose such as rem or sievert (Sv). The relationship between the units is as follows:
[133] Lard and Gray
[134] 1 rad = 0.01 Gy
[135] RAM and Sievert (Sv)
[136] 1 rem = 0.01 Sv
[137] The Sv is the Gy radiation dose multiplied by the coefficient containing the damaged tissue. For example, penetrating ionizing radiation (eg gamma and beta radiation) has a coefficient of about 1 and therefore 1Sv = -1Gy. The alpha line has a coefficient of 20, thus the alpha line 1Gy = 20Sv.
[138] By "effective amount of ionizing radiation" is meant an amount of effective ionizing radiation that kills or reduces abnormal proliferating cell propagation of a subject. As used in connection with bone marrow purging, "effective amount of ionizing radiation" refers to the amount of ionizing radiation that is effective in reducing necrosis or proliferation of malignant cells in bone marrow samples removed from a subject.
[139] "Acute exposure to ionizing radiation" or "acute radiation dose of ionizing radiation" means the radiation dose of ionizing radiation absorbed by a subject within 24 hours. In radiation therapy techniques, the acute radiation dose can be local or absorbed into the subject's whole body. Acute radiation typically exceeds 10,000 millimeters (0.1 Gy), but may be less than or equal to.
[140] By "chronic exposure to ionizing radiation" or "chronic radiation dose of ionizing radiation" is meant the radiation dose of ionizing radiation absorbed into a subject over a period of 24 hours or more. The radiation dose may be intermittent or continuous, local or may be absorbed throughout the subject's entire body. Typically, chronic radiation is less than 10,000 millimeters (0.1 Gy), but may be higher.
[141] An "effective amount of radiation-protected N- (aryl) -2-arylethenesulfonamide compound" is intended to reduce or eliminate radiation-related toxicity in normal cells of a subject and to directly direct cytotoxicity to abnormally proliferating cells of a subject. Means the amount of the effective compound. As used in connection with a bone marrow purge, an “effective amount of radiation-protected N- (aryl) -2-arylethenesulfonamide compound” is used to reduce or eliminate radiation-related toxicity in bone marrow removed from a subject and to remove it from the subject. The amount of an effective compound that has a direct cytotoxic effect on the malignant cells of the bone marrow.
[142] By "expected to be exposed to ionizing radiation" it is meant that the subject may be exposed to ionizing radiation intentionally (such as a planned radiation treatment period) or accidentally. Accidental exposures include accidental or unplanned environmental or occupational exposures.
