The novel 2-ac1 shaminomethyl-5-heteroaryl-1H-2,3-dihydro-1,4-benzodiazepine compounds and their pharmacologists) 0 acceptable salts differ from the known 1,4-benzodiazepine derivatives with a pharmacologically specific profile of action and have , in particular, clearly expressed detrimental properties with low toxicity.
Owing to their clearly pronounced analgesic properties, the compounds proposed are useful analics.
The analgesic properties of the compounds are demonstrated in a pharmacological test on small rodents and monkeys. It has been proven that the compounds of formula I can increase the pain threshold of mammals in animals. of This, in particular, has been proven in two pharmacologically standard test methods for testing the effect of light radiation on mice and the test for arthritis pain in rats. Determination of the minimum toxic dose.
Male individuals with a weight of 20-25 g
orally, the maximum dose of the test substance is 300 mg / kg. For 3 hours, symptoms of toxicity in animals are carefully observed. 24 hours after taking the medicine, all symptoms and deaths are additionally recorded. Adverse symptoms are also observed and recorded. If death or a toxic symptom is observed, then the next j moles are continuously diminished. with a dose until no more toxic symptoms occur. The smallest dose that causes a toxic symptom is referred to as the minimum toxic dose.
Arthritis pain test in rats.
Male rats of the OFA breed weighing 160-180 g were anesthetized by administering 20 mg / kg i.p. live weight. pentabarbital sodium. 0.1 ml suspension of Mycobacterium Smegmae (S1043)
in paraffin oil (0.6 mg Musobaster, O, 1 ml oil) were administered internally in the left hind paw. After 14 days, when a pronounced secondary arthritis developed, especially in the right hind paw, the action of the test substances was examined. 30 minutes before the test substance was injected, a control measurement was made in such a way that the ankle joint of the right hind paw was bent three times and the number of sounds made was counted.
Rats that do not react are separated. Three hours after the administration of the orally tested substances, the folding procedure is repeated. Animals that make a sound only once or do not make any sound at all are rated as protected from pain. Per dose is applied from 9 to 20 rats and the ED is calculated (95% confidence area) according to the method of Litehfield and Wilcoxon (1949). UNIT denotes a dose that protects 50% of the animals that have been treated.
Light emission test for mish.
The method is based on the principle of operation described by D Amour and Smith (1941). However, instead of rats, fed male and female individuals of lower weight are applied. 30 minutes before the test substance is administered, each mouse is individually placed in a cylindrical container so that it cannot rotate and move forward there. Her tail sticks out of the cylinder, being laid in a narrow recess. The determined tail point of each animal (at a distance of about 35 mm from the root of the tail) is exposed to the heat of the lamp with a known intensity and temperature of the radiation that is directly under the tail. The time in seconds that the mouse takes to drag the tail out of the light flux is determined twice, once every 30 minutes and a second time 15 minutes before the subcutaneous administration of the test substance (10 mg / kg). Those whose response time deviates by more than 25% are excluded. The reaction times are again measured 15 and 30 minutes after ingestion of the test substance and
extending the response time to more than 75% of the average value obtained by determining the same substance before taking the test substance is estimated as an anesthetic effect. As the ED (95% confidence area) of each test substance, 30 minutes after taking it, take that dose, which increases the reaction time compared to the time before taking the test substance by more than 75% for 50% of animals. The calculation is made according to the method of Litehfield and Wilcoxon (1949).
The use of formula I in the described pharmacological tests at doses ranging from 0.1-100 mg / kg has an analgesic effect.
Table 2 shows the results obtained with the test methods given (the numbers of the examples given for the compounds of formula I refer to the numbers of the examples given in Table 1).
The compounds of the formula D can be used in pharmaceutical administration forms which contain about 0.1-100 mg of active substance per unit dose.
The dosage used is adjusted according to the type of treatment to be treated and individual requirements. However, in general, in animal tests, the analgesic effect was obtained at doses of 0.1-100 mg / kg.
For the treatment of pain in humans and large nutritional supplements, for example, preparations with a content of 0.25-50 mg, in particular 1-50 mg of the active substance in a single dose, are suitable. Parenteral preparations contain, as a rule, less active substance than preparations for; oral administration.
The compounds of the formula T are used alone or in combination with pharmaceuticals & amphibiously used carriers and / or auxiliary substances in the form of solid or liquid forms. As examples of solid preparations, oral preparations may be mentioned, such as tablets, capsules, powder granules or dragees, or suppositories. Solid preparations may contain inorganic talc-type and / or organic carriers customary in pharmaceuticals.
23.
carriers of the type of milk sugar or starch, as well as pharmaceutically common auxiliary substances such as lubricants, such as magnesium stearate. Liquid preparations such as solutions, suspensions or emulsions may contain the usual dilute 1245259
whether such as water, oils or petroleum jelly and / or suspending agents such as polyoxyethylene glycol and the like. Other additives, such as preservative agents, stabilizers and wetting agents, may also be added additionally.
