    Technical field of the invention
    The present invention relates to a pharmaceutical composition which can be used as a medicament, in particular for the therapeutic treatment of dyslipidemias concomitant or consecutive to a diabetic pathology, cancers and in particular those associated with adipose tissues, neurodegenerative diseases, and for the treatment of diseases infectious, in this case HIV infection.
    Prior Art
    The pandemics of obesity, metabolic syndrome and diabetes are directly associated with an incidence of early atherosclerosis and cardiovascular (cardiac, vascular) or arterial (arteries of the neck, legs, heart, etc.) diseases.
    Even if the pathogenesis of atherosclerosis is obviously multifactorial, dyslipidemia is an important predictor of cardiovascular risk in diabetics. In type 2 diabetes, dyslipidemia results in both quantitative and qualitative abnormalities of lipoproteins (with small, dense LDL particles, enriched in cholesterol, having particularly atherogenic properties, an increase in their susceptibility to oxidation and their retention in the arterial wall), a moderate increase in triglycerides (TG), a lowering of HDL-cholesterol (HDL-c). In dyslipidemia in type 1 diabetics, quantitative abnormalities of lipoproteins are rare (except in the case of type 1 diabetes with renal involvement). However, qualitative alterations in lipoproteins are frequent and lead overall to an increase in the atherogenicity of the LDL particles and to a decrease in the anti-atherogenic power of the HDL particles.
    Most of the data on treatments acting on dyslipidemia come from type 2 diabetic patients for whom dyslipidemia is closely correlated with insulin resistance and hyperinsulinemia. On the other hand, in type 1 diabetic patients, the increased risk of cardiovascular diseases should not be overlooked and treatments for dyslipidemia should also be offered for these patients.
    On the other hand, in seropositive patients treated with combinations of antiretrovirals, one observes among the many harmful side effects, diabetes, lipodystrophy, dyslipidemia characterized by an abnormal rise in triglycerides and / or cholesterol. These infected patients also have an increased risk of developing atherosclerosis, due to the negative effect of the viral protein Nef on the transporter ABC Al (ATP-binding cassette 1), the transporter involved in the efflux of cellular cholesterol. The cells of these patients acquire phenotypic changes. These cells (progenitor stem cells, adipocytes, glial cells, monocytes, macrophages, CD4 + and CD8 + T lymphocytes, etc.) become more active, storing more lipid droplets, having a greater fusion potential. with viral particles, and would act as a reservoir for the virus, inaccessible to antiretrovirals. Enrichment of these cells with lipids, particularly at the cell membrane, could facilitate infection and viral replication.
    The membrane lipid rafts of these cells are said to play a major role. These are membrane micro-domains, also called rafts, made up of a compact assembly of lipids (glycosphingolipids and / or sphingomyelin and cholesterol) and proteins (proteins anchored to glycosylphosphatidylinositol, proteins linked to cholesterol, transmembrane proteins , doubly acetylated tyrosine kinases of the Src family, alpha subunits of heterotrimeric G proteins). Lipids acting as a solvent for membrane proteins. HIV (Human Immunodeficiency Virus) would interact with these lipid rafts both during its entry and during the budding of its virions, leading to the selective incorporation of certain lipids into the viral envelope and to the rigidity of this this. Some glycosphingolipids even have the function of an alternative entry co-factor or co-receptor for HIV. Many others, such as galactosylceramide, play an alternative receptor role in certain HIV target cells.
    This entry mechanism using lipid rafts is also observed with enveloped viruses such as measles virus, influenza virus, etc. Escherichia Coli bacteria enter mast cells by this route. Some pathogens (the prion protein, Plasmodium falciparum) use the caveolae. Caveolae represent a sub-category of these micro-domains. They contain a protein, caveolin linked to cholesterol and sphingomyelin.
    In addition, GALT (Lymphoid tissue associated with the digestive tract), the main reservoir for HIV, is made up of 80% to 90% of the body's lymphocytes, the largest contingent of memory and activated CD4 + / CCR5 T lymphocytes, cells preferred HIV-1 targets. It is the source of many immunological and architectural abnormalities during infection with this virus. The alteration of this mucosa following an early and massive depletion of CD4 + T lymphocytes, particularly Th 17 lymphocytes involved in mucosal immunity and its permeability, results in: bacterial, viral or fungal translocation from the intestinal lumen to the blood circulation, metabolic disorders, systemic immune hyperactivation, chronic inflammation and amplification of viral replication. The latter is at the origin of the progression of the disease and also of the rapid development of non-infectious comorbidities such as, cardiovascular diseases, osteoporosis, cancers linked or not to AIDS (acquired immunodeficiency syndrome), dysfunctions neurocognitive, etc.
    In addition, adipose tissue is frequently found in the vicinity of invasive and aggressive cancers, in particular breast and prostate cancer. The mature adipocytes associated with cancer will then play a predominant role in tumor progression, the acquisition of metastatic potential and in resistance to chemotoxic treatments via the secretion of pro-inflammatory cytokines, proteins of the extracellular matrix and its remodeling, SDF-1 factor, etc. Certain tumor cells overexpress glycosphingolipids, notably globotriaosylceramide (Gb3), proteins such as the CXCR4 receptor, which is also an X4 tropism co-receptor for HIV. The establishment of the CXCR4 / SDF-1 axis will then play a fundamental role in the constitution of an immunosuppressive microenvironment and the formation of a new blood supply. This dynamic interaction which is established between adipocytes, cells loaded with lipid droplets and tumor cells could be amplified under obesity conditions and explain the poor prognosis observed in cancer patients.
    On the other hand, dyslipidemias are also factors promoting neurodegenerative diseases, such as Alzheimer's disease, vascular dementia, etc. Indeed, in Alzheimer's disease, senile plaques are observed in the brains of patients, consisting of the accumulation of amyloid peptide and neurofibrillary degenerations characterized by the entanglement of a particular protein called, the tau protein. These senile plaques cause multiple cognitive deficits which would be partly corrected by acting on the metabolism of cerebral cholesterol. The beta-amyloid peptide is said to be involved in the reduction of the membrane expression of the LDL-cholesterol receptor. This mechanism, probably linked to oxidative stress, would be similar to that observed in the reduction of membrane expression of insulin receptors and would explain the links observed between Alzheimer's disease and insulin resistance. In addition, inflammatory defense reactions caused by immune cells (macrophages, microglial cells, etc.) around these senile plaques are believed to contribute to the progression of Alzheimer's disease.
    Thus, in the management of dyslipidemias and chronic inflammation which characterize a large number of diseases such as, neurodegenerative diseases, diabetes, glomerular nephropathies, cancer, AIDS, etc., the conventional hygienodietic measures remain essential, but alone, they are often insufficient and must therefore be supplemented with drug treatment.
    Lipid-lowering treatments have emerged as potential weapons for reducing the risk of cardiovascular events in diabetic patients, in those infected with HIV and with dyslipidemia. The therapeutic strategy consists of combining oral and / or injectable anti-diabetics and / or lipid-lowering drugs. The combinations are variable depending on the patient's response to therapy.
    Among the oral anti-diabetics:
    - Biguanides, they improve insulin sensitivity in the liver, muscles or fats. Their action however requires the presence of endogenous or exogenous insulin,
    - Hypoglycaemic sulfonamides and glinides, they stimulate the secretion of insulin by beta cells in the pancreas. Their effectiveness depends on the residual capacity of the pancreas to secrete insulin,
    - Alpha-glucosidase inhibitors, they slow the passage of sugar from ingested food from the intestine to the blood. He doesn't give hypoglycemia,
    - Incretins including GLP-1 (Glucagon-like peptide-1) are substances released by the body at the start of meals to stimulate insulin secretion. They are used in pharmacology either by injecting GLP-1, or by reducing its degradation by the body thanks to inhibitors of the enzyme DPP4 (Dipeptidyl peptidase-4) or gliptins,
    - SGLT2 inhibitors (Sodium / glucose co-transporter type 2) increase the elimination of glucose in the urine.
    In injectable forms, there are analogues of GLP-1, insulin (fast insulins, basal insulins and fixed mixtures of insulins).
    Among the lipid-lowering drugs, we find:
    - Statins, the most used, they are effective in lowering the cholesterol level in the blood, in particular the LDL-cholesterol level. They reduce the risk of occurrence or recurrence of diseases resulting from the narrowing or occlusion of arteries: myocardial infarction, angina pectoris, obliterating arterial disease of the lower membranes, stroke,
    - Fibrates, act through the Receptor Activated by Peroxisome Prolifers type a: PPARa. They decrease the level of blood triglycerides and increase that of HDL-cholesterol "good cholesterol". Their effectiveness in reducing the risk of occurrence of cardiovascular disease appears to be moderate,
    - Ezetimibe, selectively inhibits the intestinal absorption of cholesterol and related phytosterols,
    - Nicotinic acid, inhibits the release of free fatty acid from adipose tissue, which could contribute to the decrease in plasma LDL-c, total cholesterol (CT), VLDL-c, apo B, triglycerides (TG), Lp (a) as well as an increase in HDL-c and Apo Al, all associated with a decrease in cardiovascular risk.
    - Omega 3 fatty acids are essential fatty acids necessary for the development and proper functioning of the human body, but which the body cannot manufacture.
    However, data from recent literature has raised questions about the effect of statins on the risk of cardiovascular complications and the risk of disturbing glycemic balance. In fact, in the TNT study, diabetic patients receiving atorvastatin 80 mg had more cardiovascular events at the end of the study than non-diabetics receiving only atorvastatin 10 mg. This residual risk was also highlighted in the ACCORD-lipids study, in particular in secondary prevention and for patients with atherogenic dyslipidemia (characterized by an increase in TG and low HDL-c). On the other hand, studies (PROVE-IT or JUPITER) have shown that apart from all signs of glucose intolerance, some people develop diabetes under treatment with statins. A meta-analysis of this work confirmed a 9% increase in the risk of diabetes. Even more serious, it would seem that in postmenopausal women, this increase in risk can reach almost 50%.
    Despite this observation, it is currently not possible to do without statins because their cardiovascular benefits are such that there is no reason to question the benefit / risk ratio. Paradoxically, the trend is to intensify treatment due to a residual cardiovascular risk with statins.
    Regarding ezetimibe, fenofifbrates and niacin, beyond their respective association with statins which has proven lipid-lowering biological effects, there is only a limited amount of data on glucose homeostasis .
    In addition, in diabetic and obese patients, white blood cells, circulating monocytes, macrophages, mature adipocytes have inflammatory characteristics. They have an impact on adipose tissue and other organs since they contribute to the development of disturbances in the liver, pancreas, muscles, brain or cardiovascular system. This inflammation is demonstrated by the overexpression of biological biomarkers such as: TNFα, IL-6, adipokines, ACSL1, leukotrienes.
    The tumor necrosis factor alpha (TNFa) plays a role in the development of insulin resistance associated with obesity. It also reduces the oxidation of fatty acids in hepatocytes and skeletal muscle. It inhibits adipocyte differentiation by acting on C / EBP and PPAR. It also increases lipolysis.
    Interleukin-6 (IL-6) plays an important role in initiating and accelerating chronic inflammation. It is also involved in insulin resistance associated with obesity. The increase in these plasma levels is associated with variables (fasting plasma glucose level, LDL-c, total cholesterol, body mass index) that could contribute to the development of microvascular complications in diabetic patients.
    On the other hand, the PPAR / (gamma receptor activated by the proliferation of peroxisomes) attenuates the effect of TNFa and IL-6 in adipose tissue and thus improves insulin sensitivity. More generally, nuclear receptors, in particular PPARs, LXRs and RXRs are involved in the regulation of cholesterol effluent from different cell types by activating the transcription of the cholesterol transporters ABCA1 and ABCG1. They also increase the expression of the Niemann-Pick Cl (NPC1) and C2 (NPC2) proteins involved in the cholesterol trafficking of lysosomes. They are also involved in the downregulation of certain inflammatory genes (NF-KappaB, STAT, AP-1) by a transrepression mechanism.
    Almost all adipokines are involved in the inflammation linked to the increase in body fat and play a role in the development of insulin resistance. Their high concentrations in the blood indicate that they also play an essential role in the installation and in the development of a certain number of complications linked to obesity (diabetes and cardiovascular diseases in particular).
    It should also be noted that, the inflammation linked to diabetic atherosclerosis is correlated with the overproduction of ACSL1.
    The leukotrienes produced by the fat cells of obese people promote inflammation and insulin resistance, the first step towards diabetes.
    Furthermore, it is known that d-limonene has anti-diabetic and lipid-lowering properties, and can for this purpose be considered as a potential agent for preventing and treating metabolic disorders. Its antioxidant, anti-inflammatory and anticancer properties are known. In humans, d-limonene has demonstrated low toxicity after a single, repeated dose for one year. It can also dissolve gallstones containing cholesterol. It has a neutralizing effect on stomach acid and on the support of normal peristalsis, consequently relieves heartburn and gastroesophageal reflux (GERD).
    Jing L et al., (2013) Eur J Pharmacol 2013 September 5; 715 (1-3): 46-55. Doi: 10.1016 / j.ejphar.2013.06.022.Epub 2013 Jul 6, determined the preventive and therapeutic effects of d-limonene on metabolic disorders in mice with high fat content induced by obesity. As a preventive treatment, d-limonene reduced the size of white and brown adipocytes, it lowered serum triglycerides (TG) and fasting blood sugar levels, it also prevented the accumulation of hepatic lipids in C57BL / 6 mice fed high fat foods. In therapeutic treatment, d-limonene reduced serum TG, low density lipoprotein (LDL-c) cholesterol, fasting blood sugar levels, glucose tolerance, and increased high density lipoprotein cholesterol ( HDL-c) in obese mice.
    In addition, it is also known that lupeol (also known as Fagarsterol or Clerodol), is a pharmacologically active compound with anti-inflammatory properties. Its anti-diabetic and antioxidant properties are known. It is also known to offer substantial protection against abnormalities that manifest themselves at the early stage of hypercholesterolemic atherogenesis. Its anticancer properties are known. It should be noted that, the effective therapeutic dose of lupeol does not show any toxicity on normal cells and tissues.
    The anti-diabetic and antioxidant potential of lupeol has been studied by Gupta R et al., [Nat Prod Res. 2012; 26 (12): 1125-9. Doi: 10.1080 / 14786419.2011.560845.Epub 2011 Nov 1], In their study, lupeol suppressed the progression of diabetes after 21 days, it led to a decrease in glycated hemoglobin, glucose in serum and oxide nitric, with a concomitant increase in serum insulin levels. In addition, lupeol also increased levels of antioxidants, with a decrease in the content of reagents for thiobarbituric acid.
    Its cholesterol-lowering effect was highlighted in a study by Keishi Hata et al., (2008) [Article in Phytochemistry Letters 1 (4): 191-194.December 2008 DOI: 10.1016 / j.phytol.2008.09.007. In this study, lupeol strongly blocked the synthesis of TG and the accumulation of lipid droplets in 3T3-L1 cells stimulated by differentiation inducers.
    It is also known that beta-sitosterol inhibits the intestinal absorption of cholesterol and lowers cholesterol levels in the blood. Beta-sitosterol is also known to decrease systemic inflammation and increase immunity. Its anticancer properties are known. Its anti-diabetic and antioxidant potential are also known and referenced. Ivorra MD et al., [Pharmazie. 1990 April; 45 (4): 271-3] suggested in their study that beta-sitosterol-3-beta-D-glucoside exerts its action on intact pancreatic beta cells by stimulating the secretion of insulin.
    Furthermore, Methyl Hydroxy Chalcone Polymer (MHCP) is known as an insulin mimic. It seems to work in synergy with insulin. It is also known to reduce the resistance of fat cells to insulin, and thereby improves glucose metabolism.
    Cinnamaldehyde is known for its hypoglycemic properties, and for this purpose contributes to inhibiting oxidative stress. Cinnamaldehyde, like epicatechin, is known to prevent the aggregates of tau and beta-amyloid proteins, which are characteristic in the brains of Alzheimer's patients. It is also known for its lipid-lowering and anti-cancer properties.

    By way of example, it may comprise as a percentage by mass of the total mass of the active ingredients, a mass percentage of d-limonene substantially equal to or greater than 10% and substantially equal to or less than 55, and in particular substantially equal to or greater than 20 % and substantially equal to or less than 40%, a percentage of lupeol substantially equal to or greater than 15% and substantially equal to or less than 55%, and in particular substantially equal to or greater than 30% and substantially equal to or less than 40%, a percentage of cinnamaldehyde substantially equal to or greater than 15% and substantially equal to or less than 45%, and in particular substantially equal to or greater than 20% and substantially equal to or less than 40%, a percentage of MHCP substantially equal to or greater than 15% and substantially equal or less than 40%, and in particular substantially equal to or greater than 25% and substantially equal to or less than 35%, a percentage of beta-sitosterol when the said composition contains this ingredient, substantially equal to or greater than 10% and substantially equal to or less than 45%, and in particular substantially equal to or greater than 15% and substantially equal to or less than 30%.
    When the composition comprises MHCP or epicatechin and cinnamaldehyde their respective mass percentage relative to the total mass of the active ingredients is in particular equal and in particular substantially equal to 15%.
    The composition according to the invention also comprises at least one pharmaceutically acceptable excipient. This excipient can be solid or liquid. It can be chosen, for example, from purified water, ethyl alcohol, propylene glycol, glycerin, vegetable oils, animal oils, hydrocarbons, silicones, sugars such as glucose, levulose, wheat starch, corn starch, potato starch, xanthan gum, gum arabic, tragacanth, gum Sterculia, Guar gum or Guaranates, pectins, alginates, carrageenans, agar or Agar-Agar, gelatin, cellulose and its derivatives.
    The composition of the invention can be administered by any suitable route, for example by the oral, rectal, local (topical, for example), intraperitoneal, systemic, intravenous, intramuscular, subcutaneous or mucosal, in particular sublingual, route. , or using a patch, or alternatively in a form encapsulated in, or immobilized on, liposomes, microparticles, microcapsules, associated with nanoparticles and the like. Mention may in particular be made, by way of nonlimiting examples of excipients suitable for oral administration, talc, lactose, starch and its derivatives, cellulose and its derivatives, polyethylene glycols, polymers of acrylic acid, gelatin, magnesium stearate, animal, vegetable or synthetic fats, paraffin derivatives, glycols, stabilizers, preservatives, antioxidants, wetting agents, anti-caking agents, dispersants, emulsifiers , taste modifiers, penetrants, solubilizers. The techniques for formulating and administering drugs and pharmaceutical compositions are well known in the art considered here, those skilled in the art can in particular refer to the work Remington's Pharmaceutical Sciences, latest edition.
    According to the invention, the composition can be advantageously administered orally, by intravenous injection.
    Advantageously, the composition according to the invention is suitable for being administered orally or intravenously at a dose equal to or greater than 40 mg / kg / 24h and equal to or less than 200 mg / kg / 24h in one or more doses to a mammal. presenting such a need.
    By way of examples, the composition of the invention can be used in the preventive and / or curative treatment of dyslipidemias, insulin resistance, iatrogenic hyperlipidemias, in particular in patients infected with HIV and treated with combinations of antiretrovirals. , in the preventive and / or curative treatment of atherosclerosis, coronary artery disease chosen from angina or myocardial infarction, carotid artery disease, in particular stroke and aneurysm cerebral, peripheral arterial disease, pulmonary embolism.
    The composition according to the invention can advantageously be used in patients suffering from a chronic inflammatory disease and / or resulting from an infection caused by at least one pathogenic agent and / or from systemic immune hyperactivation and / or from a lipid imbalance and / or dysfunction of the cholesterol cell transporter, in particular in chronic inflammatory tissue disease relating to diabetes, obesity, AIDS, Crohn's disease, hepatocellular insufficiency, fatty liver disease , cholecystitis, gallbladder stones, in autoimmune diseases, including type 1 diabetes, autoimmune thyroiditis, autoimmune liver disease, autoimmune uveitis and autoimmune retinitis, Gougerot-Sjôgren syndrome , systemic lupus erythematosus, multiple sclerosis, rheumatoid arthritis, scleroderma, polymyositis and mixed connectivity, in neurodegic diseases enerative, in this case, Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis or charcot disease, vascular dementias, in glomerular nephropathies, in cancers, in particular those associated with tissue adipose.
    In the case of AIDS treatment, the Applicant has demonstrated that the composition according to the invention gives good results at least in vitro and has shown very low toxicity for healthy liver cells.
    The mode of action of the composition of the invention is not fully understood. It is more than likely that it acts simultaneously on different mechanisms responsible for the diseases cited in the prior art. It would exert its action by a synergistic regulatory effect on nuclear receptors, in particular PPARs, LXRs and RXRs, thus allowing the efflux of cellular cholesterol, the inhibition of the production of pro-inflammatory cytokines, the inhibition of formation, overexpression and / or dysfunction of certain sphingolipids, in particular glycosphingolipids (such as globotriaosylceramide, monosialogangloside), membrane proteins, in particular LRP1, the T cell receptor (TCR), CXCR4. It would also inhibit the chemokine protein SDF-1, a related ligand of CXCR4, and consequently the formation of the CXCR4 / SDF-1 axis which plays a fundamental role in the establishment of an immunosuppressive microenvironment, the formation of a new blood supply, tumor growth and metastasis.
    Thus, the composition according to the invention allows the destructuring, the restructuring of the lipid composition of cells, and in particular of membrane lipid rafts, targets of bacteria, parasitic protozoa and viruses, and thereby prevents the stabilization of these micro- areas, the establishment of a fusion complex, synapse formation, endocytosis, and therefore ultimately the penetration of these pathogens into cells.
    In addition, the modification of the lipid composition of these membrane micro-domains causes a change in conformation, an alteration in the functional or dysfunctional activity of the proteins found there, in particular the receptors coupled to the G proteins, and ultimately a alteration of cell signaling pathways involved in many pathophysiological processes, including infections caused by pathogens, in acquired immunodeficiency syndrome, cancer, obesity, metabolic diseases, autoimmune diseases and diseases neurodegenerative.
    This lipid disorganization could also take place in the envelope of infectious agents, and would then modify the conformation of the information proteins involved in the infection process, their binding to their target cells. This mechanism would apply to viruses, bacteria with biophysical and biochemical properties similar to their target cells, particularly at the level of the lipid bilayer envelope.
    The composition according to the invention can advantageously be used to decrease or inhibit the resistance of infectious agents to treatments, the inflammatory phenotype of the cells, oxidative stress, the senescence of the immune cells, and to increase an innate and adaptive immune response.
    In addition, the composition according to the invention can be used in the treatment of infections caused by pathogens and their various variants, in particular retroviruses (lentiviruses including HIV-1 and HIV-2, oncoviruses, and spumaviruses) , measles virus, influenza virus, smallpox virus, yellow fever virus, West Nile virus, vesicular stomatitis virus (VSV), hepatitis B virus ( HBV), hepatitis C virus (HCV), cytomegalovirus (CMV), Ebola virus, certain rotaviruses, in the treatment of infection with Escherichia Coli, Mycobacterium tuberculosis, plasmodium falciparum, and cancer treatment.

    [Experimental results]
    Different cells have been studied: 3T3-L1 cells, monocytes, macrophages, white blood cells, hepatocytes, adipocytes. They were selected on the basis of their ability to accumulate lipid droplets. These cells, especially white blood cells, have inflammatory characteristics in diabetics.
    The cells were kept in DMEM, supplemented with 10% fetal bovine serum (FBS) and a 1% antibiotic-antimycotic solution (PSM), containing, penicillin, streptomycin and amphotericin B under standard growth conditions. (5% CO2, 37 ° C, a humidified atmosphere). The above compositions were dissolved and diluted in DMSO. The abovementioned cells were treated with the solutions (10-80 μM) for 48 h in complete cell media. All treatment and control protocols were prepared as described above.
    The above-mentioned solutions have resulted in a selective inhibition of the differentiation of 3T3-L1 cells into adipocytes even in the presence of an additional prodifferential agent such as rosiglitazone. The effect of this differentiation was quantified by OR Red O staining: Changes in the expression of genes and proteins associated with differentiation and adipogenesis were observed.
    The above solutions resulted in a significant inhibition of the accumulation of lipid droplets in monocytes, macrophages, white blood cells, hepatocytes, regulated the expression of the gamma receptor activated by peroxisome proliferation (PPARy) resulting in a decrease in pro-inflammatory cytokines, inhibited the formation, overexpression and / or dysfunction of certain membrane lipids (sphingolipids, in particular glycosphingolipids), of certain membrane proteins depending on the concentration. They also reduced the affinity of pathogens for their target cells.
    These results taken as a whole suggest that this pharmaceutical composition inhibits the production of adipose tissue and thereby reduces insulin resistance. Extrapolation can be made to visceral adipose tissue (TAV) or to subcutaneous adipose tissue (TA sc) which plays a central role in the pathophysiology of the Metabolic Syndrome. Furthermore, this pharmaceutical composition could inhibit tumor progression and resistance to anticancer treatments via the inhibition of secretions from adipocytes associated with cancers (CAA), in particular pro-inflammatory cytokines (such as TNFa, ILtp, IL6, IL8), pro-angiogenic molecules (such as VEGF for Vascular Endothelial Growth Factor), chemokines (such as MCP-1 for monocyte chemoattracting protein-1, SIP for sphingosine-1-phosphate), growth factors (such as HGF , for Hepatocyte Growth Factor), the proteins of the extracellular matrix and its remodeling as well as the release of free fatty acids. It decreases or even inhibits the infectivity of pathogens as well as their different variants.
    Therefore, this pharmaceutical composition can be rightly used in the preventive and curative treatment of obesity, diabetes, dyslipidemia and their consequences, neurodegenerative diseases, infections caused by pathogens, cancers, especially those associated to fatty tissue, such as breast cancer, prostate cancer.
