Definitions
- the present invention relates to novel benzimidazole and benzothiazole derivatives, process for their preparation, novel intermediates obtained, their use as medicaments, the pharmaceutical compositions containing them and the novel use of such benzimidazole and benzothiazole derivatives.
- the present invention relates more particularly to novel sulfonic ester derivatives of benzimidazoles and benzothiazoles.
- the present invention relates to novel derivatives with inhibitory effects vis-à-vis protein kinases.
- the products according to the present invention can thus notably be used for the prevention or the treatment of diseases that can be modulated by the inhibition of protein kinases.
- the products according to the present invention exhibit in particular an anticancer activity, via the modulation of the activity of proteins, in particular kinases.
- the present invention thus relates to the use of these derivatives as kinase inhibiting agents and more particularly as anticancer agents.
- the present invention also relates to the use of said derivatives for the preparation of a medicament for the treatment of humans.
- most of the commercial compounds used in chemotherapy are cytotoxic drugs that pose significant problems of side effects and tolerance by patients. These effects could be limited insofar as the drugs used act selectively on cancer cells, excluding healthy cells.
- One of the solutions to limit the undesirable effects of chemotherapy may therefore consist of the use of drugs acting on metabolic pathways or constitutive elements of these pathways, mainly expressed in cancer cells, and which would be little or no expression in healthy cells.
- Such protein kinases belong in particular to the following group: AuroraA, AuroraB, members of the family of CDKs (CDK1, 2,4,5,7,9), RON, Tie2, members of the family of VEGFRs (VEGFR1 or flt -1, VEGFR2 or KDR or flk-1, VEGFR3), FGFRs (FGFR1, FGFR2, FGFR3, FGFR4, FGFR5), MET as well as mutants of the MET protein, EGFR, Fak, IGF-1 R. PDGFR. More particularly, the protein kinase MET is mentioned.
- Protein kinases are a family of enzymes that catalyze the phosphorylation of hydroxy groups of protein-specific residues such as tyrosine, serine or threonine residues. Such phosphorylations can greatly alter the function of proteins: thus, protein kinases play an important role in the regulation of a wide variety of cellular processes, including metabolism, cell proliferation, cell adhesion and motility, Cell differentiation or cell survival, with some protein kinases playing a central role in the initiation, development, and completion of cell cycle events.
- angiogenesis is the process in which new vessels are formed from already existing vessels. If necessary, the vascular system has the potential to generate a network of new vessels to maintain the proper functioning of tissues and organs.
- Angiogenesis is a complex multi-step process that includes activation, migration, proliferation and survival of endothelial cells.
- angiogenesis In adults, angiogenesis is quite limited, appearing mainly only in repair processes after wounding or vascularization of the endometrium (Merenmies et al., CeII Growth & Differentiation, 8, 3-10, 1997). Non-controlled angiogenesis is found, however, in certain pathologies such as retinopathy, psoriasis, rheumatoid arthritis, diabetes, muscle degeneration, or cancers (solid tumors) (Folkman, Nature Med., 1, 27-31, 1995).
- VEGF-R2 vascular endothelial growth factor receptor 2
- FLK-1 kinase insert domain receptor
- FGF-R fibroblast growth factor receptor
- Tie-2 vascular endothelial growth factor receptor 2
- VEGFRs vascular endothelial growth factor receptors
- the VEGFR family includes VEGFR-1 (Flt-1), VEGFR-2 (KDR) and VEGFR3 (Flt4).
- the VEGF-R2 receptor which is expressed only in endothelial cells, binds to the VEGF angiogenic growth factor, and thereby mediates a transduction signal via the activation of its intracellular kinase domain.
- the direct inhibition of the kinase activity of VEGF-R2 makes it possible to reduce the angiogenesis phenomenon in the presence of exogenous VEGF (Strawn et al., Cancer Research, 56, 3540-3545, 1996), a process demonstrated in particular by using mutants of VEGF-R2 (Millauer et al., Cancer Research, 56, 1615-1620, 1996).
- VEGF-R2 receptor appears to have no other function in the adult than that related to the angiogenic activity of VEGF.
- a selective inhibitor of the kinase activity of VEGF-R2 should demonstrate little toxicity.
- VEGF expression contributes to the survival of tumor cells after chemo- and radiotherapeutics highlighting the potential synergy of KDR inhibitors with other agents (Lee CG., Heijn M. et al., (2000), Cancer Research, 60 (19), 5565-70).
- Inhibitors of angiogenesis could thus be used in the first line against the emergence or re-growth of malignant tumors.
- VEGFR-2 VEGFR-2
- cyclin dependent kinases as well as Aurora-2 (or Aurora-A).
- CDKs cyclin-dependent kinases
- endogenous inhibitors of CDKs that are activated family of INK4 and KIP / CIP
- INK4 and KIP / CIP endogenous inhibitors of CDKs
- Cyclin E activates the CDK2 kinase which then acts to phosphorylate the pRb protein (retinoblastoma protein) resulting in commitment to irreversible cell division and transition to the S phase (PL Toogood, Medicinal Research Reviews (2001), 21 (6)).
- the CDK2 and CDK3 kinase are required for progression in G1 phase and S phase entry.
- When complexing with cyclin E they maintain the hyperphosphorylation of pRb to help the progression of the G1 phase in S.
- Cyclin A CDK2 plays a role in the inactivation of E2F and is necessary for the realization of the S phase (TD Davies et al (2001) Structure 9 , 389-3).
- the CDK1 / cyclin B complex regulates cell cycle progression between the G2 phase and the M phase.
- the downregulation of the CDK1 / Cyclin B complex prevents normal cells from entering S phase before the G2 phase has been correctly and completely performed.
- CAKs cyclin-dependent kinases
- This kinase named aurora2, STK15 or BTAK belongs to the family of serine / threonine kinases. Bischoff et al. have shown that Aurora2 is oncogenic, and is amplified in human colorectal cancers (EMBO J, 1998, 17, 3052-3065). This has also been exemplified in cancers involving epithelial tumors such as breast cancer.
- the present invention also relates to molecules that inhibit the tyrosine kinase activity of different kinases and most particularly inhibit the activity of MET.
- MET or Hepatocyte Growth Factor Receptor
- HGF Hepatocyte Growth Factor
- MET is a receptor with tyrosine kinase activity expressed in particular by epithelial and endothelial cells.
- HGF Hepatocyte Growth Factor
- HGF is described as the specific ligand of MET.
- HGF is secreted by the mesenchymal cells and activates the MET receptor that moderates. As a consequence, the receptor autophosphorylates on tyrosines of catalytic domain Y1230, Y1234 and Y1235.
- MET stimulation by HGF induces proliferation, scattering (or dispersion), cell motility, resistance to apoptosis, invasion and angiogenesis.
- MET like HGF, are found to be overexpressed in many human tumors and a wide variety of cancers. MET is also found amplified in gastric tumors and glioblastomas. Numerous point mutations of the MET gene have also been described in tumors, in particular in the kinase domain, but also in the juxtamembrane domain and the SEMA domain. Overexpression, amplification or mutations cause constitutive activation of the receptor and deregulation of its functions.
- the present invention thus relates to novel inhibitors of protein kinases as defined above, in particular having an anti-proliferative activity.
- the present invention thus relates in particular to new inhibitors of protein kinases as defined above, which can be used for an anti-proliferative and anti-metastatic treatment, in particular in oncology.
- the present invention also relates to novel protein kinase inhibitors as defined above, which can be used for antiangiogenic treatment, in particular in oncology.
