MS351 is an antagonist of chromobox 7 (CBX7) that acts by binding the CBX7 chromodomain. It enhances the binding of long noncoding RNA to the CBX7 chromodomain when used at 25 μM. MS351 induces transcriptional derepression of CBX7 target genes, including p16 (INK4a), in mouse embryonic stem cells and human prostate cancer PC3 cells.
BMS-351 is a potent and selective, nonsteroidal CYP17A1 lyase inhibitor with robust selectivity over steroidogenic CYPs 21A2 and 11B1. BMS-351 emerges as an outstanding preclinical candidate to treat CRPC and is likely to minimize the side effects of current therapies due to its exceptional selectivity. BMS-351 is potentially useful for the Treatment of Prostate Cancer.
