Definitions

  • the subject of the present invention is new inhibitors of cdc25 phosphatases, and in particular of cdc25-C phosphatase.
  • kinases The transition between the different phases of the cell cycle during mitosis or meiosis is controlled by a set of proteins whose enzymatic activities are associated with different states of phosphorylation. These states are controlled by two main classes of enzymes: kinases and phosphatases.
  • cyclin-dependent kinases play a major role in this control of the cell cycle. Their activities are regulated by their molecular associations with other proteins called cyclins. In addition, endogenous inhibitors are able to prevent these activities.
  • endogenous inhibitors are able to prevent these activities.
  • inhibitors of this family of kinases have already been identified and studied in several therapeutic fields such as oncology to prevent the division of tumor cells (McDonald and el-Deiry, Int. J.
  • CDKs are controlled by two other families of enzymes which work in opposition (Jessus and Ozon, Prog. Cell Cycle Res. (1995), 1, 215-228).
  • the first groups kinases such as Weel and Mikl which deactivate CDKs by phosphorylating certain amino acids (Den Haese et al., Mol. Biol Cell (1995), 6, 371-385).
  • the second groups together phosphatases such as Cdc25 which activate CDKs by dephosphorylating the tyrosine and threonine residues of CDKs (Gould et al., Science (1990), 250, 1573-1576).
  • cyclin B is itself phosphorylated by the Cdc2 kinase (cdkl) with which it is associated (Borgne et al., J. Biol Chem. (1999), 274, 11977-11986).
  • cdc25-A a family of 3 genes, cdc25-A, cdc25-B and cdc25-C, code for the human cdc25 proteins.
  • variants from alternative splicing of the cdc25B gene have been identified: these are cdc25Bl, cdc25B2 and cdc25B3 (Baldin et al., Oncogene (1997), 14, 2485-2495).
  • the proteins encoded by these variants would be localized differently in the cell (Davezac et al., Oncogene (2000), 19, 2179-2185).
  • the activity of cdc25 is regulated by the kinases Cdc2 and Cdk2. But in the absence of the cdc2 kinase, the activity of cdc25 can be activated by other kinases (Izumi and Maller, Mol. Biol. Cell (1995), 6, 215-226). Among these, the protein chkl phosphorylates cdc25-C on a serine at position 216, which increases its affinity for a chaperone protein 14-3-3. This bond neutralizes cdc25-C and consequently maintains the cdkl enzyme in a phosphorylated and therefore inactive state, not allowing entry into mitosis.
  • the chaperone protein allows the complex to pass into the cytoplasm thanks to a protein motif for exporting the nucleus (Lopez-Girona et al., Nature (1999), 397, 172-175).
  • a chemical inhibitor of chkl allows a cell to continue its cell cycle despite the induction of DNA breakage. This aspect makes it possible to increase the effectiveness of certain cytotoxic compounds such as campthotecin (Jackson et al., Cancer Res. (2000), 60, 566-572).
  • - Lymphomas in circulating lymphocytes, the expressions of the cdc25-B1 and -B3 RNAs are detected by RT-PCR while the expressions of cdc25-A, -B2 and -C are very weak or not detectable.
  • the analysis of these genes in non-Hodgkin's lymphomas shows a strong expression of cdc25-A and -B2 in approximately 35% of the tumors.
  • the cdc25-B1 and -B3 variants are detected in all of the tumors analyzed.
  • the expression of cdc25-C remains very weak in all of the samples (Hernandez et al., Int. J.
  • Vitamin K3 also known as menadione, was the first selective cdc25 phosphatase inhibitor described (Ham et al., Bioorg. Med. Chem. Lett. (1998) 8, 2507-2510). Since then, other cdc25 inhibitors have been identified and have a micromolar inhibitory activity on recombinant enzymes. Among these products, we can note:
  • Some of the compounds from a Ugi library containing groups mimicking phosphates are non-competitive inhibitors of cdc25-A which do not act on the active site.
  • the most active compound has an IC 50 of 0.5 ⁇ M and the interaction site is being identified (Bergnes et al., Bioorg. Med.
  • A represents a free radical scavenger radical, for example a substituted phenyl radical
  • X and Y are linking chains, for example alkylene, alkylene carbon, carbonylalkylene radicals;
  • R represents H or alkyl
  • B represents a carbocyclic or heterocyclic aryl radical, and preferably the 2-thienyl radical.
  • the invention provides new inhibitors of cdc25, and in particular of cdc25-C, which correspond to the general formula (I) defined below. These compounds are capable of being used as medicaments, in particular in the treatment of the following diseases / disorders: • inhibition of tumor proliferation alone or in combination with other treatments;
  • the compounds of the present invention are also, because of their inhibitory properties for cdc25 phosphatases, capable of being used to inhibit the proliferation of microorganisms, in particular yeasts.
  • One of the advantages of these compounds is their low toxicity on healthy cells. The Applicant has therefore now surprisingly discovered that the compounds corresponding to the general formula (!
  • A represents a radical (Al)
