What is GSK-3326595?

Description

GSK3326595 (1616395-22-3) is a potent (IC50?= 6.2nM), selective (>4000-fold over 20 other methyltransferases), SAM uncompetitive, peptide competitive inhibitor of PRMT5.1?PRMT5 inhibition activated the p53 pathway?via?induction of alternative splicing of MDM4 leading to a potent anti-proliferative response both?in vitro?and?in vivo. Combination therapy with palbociclib (CDK4/6 inhibitor, Focus Cat.# 10-4760) and GSK3326595 lead to increased efficacy of palbociclib in treating native and resistant models of melanoma via regulation of the PRMT5-MDM4 axis.2?Currently in clinical trials.3

The Uses of GSK-3326595

GSK-3326595 is a protein arginine methyltransferase 5(PRMT5) inhibitor under clinical trial.
