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. (c) 2008 Elsevier Ltd.
