GSK3368715, a potent inhibitor of type I protein arginine methyltransferases (PRMT), could inhibit PRMT1, 3, 4, 6 and 8 with Kiapp vaules ranging from 1.5 to 81 nM.
GSK3368715 is an orally active, reversible, and S-adenosyl-L-methionine (SAM) uncompetitive type I protein arginine methyltransferases (PRMTs) inhibitor (IC50s: 3.1 nM (PRMT1), 48 nM (PRMT3), 1148 nM (PRMT4), 5.7 nM (PRMT6), 1.7 nM (PRMT8)). It has strong anti-cancer activity.
Selective protein arginine methyltransferase 1 (PRMT1) inhibitor (IC50 = 1.8 μM). Exhibits five-fold selectivity for PRMT1 over PRMT6 and >250-fold selectivity over PRMT3 and CARM1.
