Synthesis, biological evaluation and 3D-QSAR study of novel 4,5-dihydro-1H-pyrazole thiazole derivatives as BRAF(V⁶⁰⁰E) inhibitors.

Many reports implied that the BRAF serine/threonine kinase was mutated in various types of human tumors, which were related with cell growth, survival and differentiation. To provide new therapeutic opportunities, a series of novel 4,5-dihydro-1H-pyrazole derivatives (6a-10d) containing thiazole moiety as potential V600E mutant BRAF kinase (BRAF(V600E)) inhibitors were designed and synthesized. All compounds were evaluated in vitro for anticancer activities against WM266.
