Small-molecule High-throughput Screening Identifies an MEK Inhibitor PD198306 that Enhances Sorafenib Efficacy via MCL-1 and BIM in Hepatocellular Carcinoma Cells.

ABSTRACT:

Background

Sorafenib is the most widely used systematic therapy drug for treating unresectable Hepatocellular Carcinoma (HCC) but showed dissatisfactory efficacy in clinical applications.

Objective

We conducted a combinational quantitative small-molecule high-throughput screening (qHTS) to identify potential candidates to enhance the treatment effectiveness of sorafenib.

Methods

First, using a Hep3B human HCC cell line, 7051 approved drugs and bioactive compounds were screened, then the primary hits were tested with/without 0.5 μM sorafenib respectively, the compound has the half maximal Inhibitory Concentration (IC50) shift value greater than 1.5 was thought to have the synergistic effect with sorafenib. Furthermore, the MEK inhibitor PD198306 was selected for the fu
