Definitions
- the subject of the invention is a new use in therapy of indirubin derivatives.
- indirubin belongs to the indigoids family.
- the term indigoide is used as the generic name for the dyes in the indigo group. These are bis-indoles, derived from various natural sources by fermentation, oxidation and dimerization in the presence of light.
- CDK inhibitory properties which cause a cell cycle arrest, give these derivatives of 1 indigoids an interest in the treatment of pathologies linked to the loss of proliferation control such as cancers, psoriasis, cardiovascular diseases, infectious diseases, nephrology, neurodegenerative diseases and viral infections.
- This kinase is an essential part of the WNT signal pathway. It is involved in multiple physiological processes: regulation of the cell cycle by controlling the levels of cyclin Dl and ⁇ -catenin, dorsoventral formation during development, action of insulin on glycogen synthesis, axonal outgrowth, neurotoxicity of HIV-1 mediated by Tat, et al.
- GSK-3 ⁇ and CDK5 are responsible for a good part of the abnormal hyperphosphorylation of the tau protein binding microtubules as observed in the helically paired filaments in Alzheimer's disease.
- the invention provides a solution to these problems with the use of high-efficiency indirubins with IC 50 of less than 10 ⁇ M, and more generally of the order of 5 to 50 nM, for the manufacture of GSK inhibitor drugs. -3 ⁇ .
- R and R identical or different, represent a hydrogen atom, a halogen atom; a hydroxy group; a methylenehydroxy group; an alkyl or alkyloxy or methylenealkoxy radical, with straight or branched chain, from C1 to C18; a cycloalkyl radical having 3 to 7 carbon atoms, optionally comprising one or more heteroatornes; a substituted or unsubstituted aryl, aralkyl or aryloxy radical, optionally comprising one or more heteroatoms; a mono-, di- or trialkylsilyl group having 1 to 6 carbon atoms, independently of each other, in each case, in the straight or branched chain alkyl group; a mono-, di- or triarylsilyl group, with substituted or unsubstituted aryl groups, independently of each other, in each case; a trifluoromethyl group; a -COM group; -COOM; or -CH 2 COOM, with
- one or more atoms of one or more benzene rings are replaced by nitrogen atoms.
- one or more aromatic or non-aromatic ring systems which may include one or more heteroatoms independently of one another, are condensed to the indirubin system.
- the indirubin derivatives of formula (I) are linked to a polyethylene glycol ester or to a polyethylene glycol ether by bonds, respectively, ester or ether.
- the invention relates more specifically to the indirubin derivatives having an IC 50 with respect to GSK-3 ⁇ of less than 10 ⁇ M and preferably of 1 ⁇ M, and in particular those with an IC 50 of less than 50 nM.
- R a hydrogen atom, halogen, alkyl, -S0 3 H, -S0 2 NH 2, -S0 2 -N (CH 3) 2, -S0 2 -NC 2 H 5 - OH, - S0 2 -N- (C 2 H 5 -OH) 2 , -S0 2 -NH-CH 3 ,
- R 4 and R 8 independently of one another: a hydrogen or halogen atom
- R an alkyl or aryl radical, the other substituents given in formula (I) representing a hydrogen atom.
- Derivatives of this family constituting high-efficiency GSK-3 ⁇ inhibitors with IC 50 of less than 5 ⁇ M, most generally of 1 ⁇ M, or even 50 nM, advantageously include substituents R 1 , R 3 , R 4 and R 8 with the following meanings:
- R 1 alkyl, in particular methyl, and phenyl,
- - R hydrogen, halogen (F, Cl, Br, I), N0 2, - S0 3 H, -S0 2 NH 2, -S0 2 -N (CH 3) 2, -S0 2 -NC 2 H 5 - 0H, -S0 2 -N- (C 2 H 5 -0H) 2 , -S0 2 -NHCH 3 ,
- halogen in particular I or Br, the other substituents given in formula (I) representing a hydrogen atom.
- Particularly preferred derivatives are chosen from indirubin, 5-iodo-indirubin, 5-bromo-indirubin, 5-chloro-indirubin, 5-fluoro-indirubin, 5-methyl-indirubin, 5-nitro -indirubin, 5-SO 3 H-indirubin, 5'-bromo-indirubin, 5-5 '-dibromo-indirubin or 5'-bromo-indirubin 5-sulfonic acid.
- R 3 represents a halogen atom, in particular I, or a group -SO 3 Na.
- the corresponding derivatives advantageously have an IC 50 with respect to GSK-3 ⁇ of less than 100 nM, and even for many of them less than 50 nM.
- Preferred derivatives of this group are chosen from indirubin-3 '-monoxime, 5-iodo-indirubin-3' -monoxime and 5-SO 3 Na-indirubin-3 '-monoxime.
- the derivatives defined above have already been described as inhibitors of CDKs, as well as other indigoids derived, for example, from indigo or isoindigo.

- the drugs produced in accordance with the invention using the indirubin derivatives defined above can be used for the treatment of pathologies in which GSK-3 ⁇ is involved.
- GSK-3 ⁇ inhibitors can be used as insulin mimetics. It is recalled that insulin acts by a cascade of biochemical events leading to an inhibition of GSK-3 ⁇ and that this inhibition is responsible for the response of cells to 1 insulin.
- these drugs are of great interest for the treatment of neurodegenerative diseases.
- the hyperphosphorylation of the tau protein caused by CDK5 and GSK-3 ⁇ can indeed be inhibited by the indirubin derivatives.
- These drugs are also effective for the treatment of diseases caused by single-celled parasites such as malaria, trypanosomes, leishmanias, toxoplasmas, pneumocystis and others, or multi-cellular parasites, such as fungi and worms.
- the active ingredients used in therapeutically effective amounts, are mixed with the pharmaceutically acceptable vehicles for the chosen mode of administration.
