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.
PRMT5-IN-19 (Compound 41) is a potent orally active PRMT5 inhibitor, exhibiting selectivity towards the SAM-binding pocket of PRMT5 with IC50 values of 23.9 nM (radioactive biochemical assay) and 47 nM (AlphaLISA assay). It effectively blocks methyltransferase activity and demonstrates high specificity against other PRMTs and PKMTs. PRMT5-IN-19 exerts anti-proliferative effects through the induction of apoptosis and holds potential in cancer-related research [1].
DC_C66 DC_C66 has good selectivity for CARM1, PRMT1 (IC50 = 21μM), PRMT6 (IC50 = 47μM) and PRMT5. It is a cell-permeable, selective co-activator related arginine methyltransferase 1 (CARM1) inhibitor with IC50 of 1.8 μM.
Bisubstrate inhibitor 78 is an inhibitor of nicotinamide N-methyltransferase (NNMT; IC50= 1.41 μM).1It binds the NNMT active site in the binding pockets for the NNMT substrates S-adenosyl-L-methionine (SAM) and nicotinamide . Bisubstrate inhibitor 78 is selective for NNMT over histone-lysine N-methytransferase NSD2 and protein arginine methyltransferase 1 (PRMT1; IC50s = >50 μM for both). It reduces levels of 1-methylnicotinamide in, and inhibits proliferation of, HSC-2 oral cancer cells when used at a concentration of 100 μM.This compound is unstable in powder form and other related salt forms are recommended.
