Discovery of potent and selective c-Met inhibitors for MET-amplified hepatocellular carcinoma treatment

Eur J Med Chem. 2024 Jan 15:264:116025. doi: 10.1016/j.ejmech.2023.116025. Epub 2023 Dec 5.

Abstract

Hepatocellular carcinoma (HCC) is a prevalent and lethal malignancy worldwide. The MET gene, which encodes receptor tyrosine kinase c-Met, is aberrantly activated in various solid tumors, including non-small cell lung cancer and HCC. In this study, we identified a novel c-Met inhibitor 54 by virtual screening and structural optimization. Compound 54 showed potent c-Met inhibition with an IC50 value of 0.45 ± 0.06 nM. It also exhibited high selectivity among 370 kinases and potent anti-proliferative activity against MET-amplified HCC cells. Moreover, compound 54 displayed significant anti-tumor efficacy in vivo, making it a potential candidate for HCC treatment in future studies.

Keywords: Hepatocellular carcinoma; Selectivity; Structural optimization; c-Met inhibitor.
