The present invention relates to compounds of formula (I) inhibiting Discoidin Domain Receptors (DDR inhibitors), methods of preparing such compounds, intermediate compounds useful in such preparations, pharmaceutical compositions containing them and therapeutic use thereof. The compounds of the invention may be useful for instance in the treatment of many disorders associated with DDR mechanisms.
Design, synthesis, and biological evaluation of novel Bcr-AblT315I inhibitors incorporating amino acids as flexible linker
toward T315I mutant based on previously reported dibenzoylpiperazin derivatives. We proposed that incorporation of flexiblelinker could achieve potent inhibition of Bcr-AblT315I by avoiding steric clash with bulky sidechain of Ile315. A library of 28 compounds with amino acids as linker has been developed and evaluated. Among them, compound AA2 displayed the most potent activity against Bcr-AblWT and
CML. Broadening the chemical diversity of Bcr-Abl kinaseinhibitors to overcome drug resistance is a current medical demand for CML treatment. As a continuation to our research, a series of compounds with heteroaromatics-trizole scaffold as hinge binding moiety (HBM) were developed as Bcr-Abl inhibitors based on in silico modeling analysis. Biological results indicated that these compounds exhibited
