Design, synthesis and biological evaluation of pyrazole derivatives as potential multi-kinase inhibitors in hepatocellular carcinoma.

摘要

We described the optimization, by molecular modelling, of small pyrazole derivatives, as kinase inhibitors, obtained through a 1,3-dipolar cycloaddition between nitrile imines and functionalized acetylenes. The two compounds, selected as potential agents active against hepatocellular carcinoma (HCC) were then evaluated in爒itro for their biological activity on HCC-derived cell lines. The compounds show a promising inhibitory growth efficacy (IC(50) 50-100牸M) in SNU449 cell line, as well as block of cell cycle progression and induction of apoptosis, and can be considered as lead compounds for further SAR developments.
