Synthesis of small molecule inhibitors of the orphan nuclear receptor steroidogenic factor-1 (NR5A1) based on isoquinolinone scaffolds.

摘要

Three synthetic routes were developed for structure-activity relationship (SAR) studies of HTS-derived isoquinolinone inhibitor probes for the orphan nuclear receptor steroidogenic factor-1 (NR5A1). Among the new analogs reported herein, 31 and 32 have improved potency, lower cellular toxicity, and improved selectivity compared to the initial HTS-derived leads 1 and 2.
