Definitions
- the present invention relates to novel 6-aryl / heteroalkyloxy benzothiazole and benzimidazole derivatives, process for their preparation, novel intermediates obtained, their use as medicaments, the pharmaceutical compositions containing them and the novel use of such derivatives.
- aryl / heteroalkyloxy benzothiazole and benzimidazole are novel 6-aryl / heteroalkyloxy benzothiazole and benzimidazole.
- the present invention relates more particularly to novel 6-aryl / heteroalkyloxy benzothiazole and benzimidazole derivatives having anticancer activity, via the modulation of the activity of proteins, in particular kinases.
- Protein kinase is a family of enzymes that catalyze the
- protein kinases play an important role in the regulation of a wide variety of cellular processes, including metabolism, proliferation
- 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 kinases.
- kinases for which modulation of activity is desired MET and RON as well as mutants of MET and RON proteins are preferred.
- the present invention also relates to the use of said derivatives for the preparation of a medicament for the treatment of humans.
- compositions having anticancer activity in particular by acting against to kinases.
- kinases for which modulation of activity is desired MET and RON are preferred.
- 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.
- 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.
- RON receptor of France origin
- c-MET and RON are the only members of the existing MET family in humans and the only tyrosine kinase receptors to possess a SEMA domain in their extracellular part.
- RON protein is ubiquitously expressed in different cell types but mainly in cells of epithelial origin.
- the RON ligand is the hepatocyte growth factor-like protein (HGFL) also known as the macrophage-stimulating protein (MSP).
- MSP is mainly produced inactive form by hepatocytes.
- MSP activates RON by autophosphorylation of two tyrosines of the catalytic domain Y1238 and Y1239 and two tyrosines in the C-terminal portion (Y1353 and Y1360).
- Activation of RON induces a panel of pleiotropic effects including proliferation, tubular morphogenesis, angiogenesis, cell motility, invasion and resistance to apoptosis and anoikis.
- RON Overexpression of RON and its mutations appear to play a potential role in tumorigenesis and metastasis formation. Overexpression of the receptor and alternative transcripts have both been identified in breast, colon, and ovarian cancers. RON, as well as MSP are overexpressed in non-small cell lung cancers and pancreatic cancers.
