Protein Lysine Methyltransferase Inhibitor, UNC0321

Описание:

A cell-permeable quinazoline analog that potently and selectively inhibits PKMT G9a with IC50s equal to 6 µM and 9 µM in two biochemical assays (CLOT and ECSD respectively), and a Morrison Ki of 63 pM, which is about 250-fold more potent compared with a close analog BIX01294 (Cat. No. 382190). Also inhibited GLP with reduced potency (15 µM in an ECSD enzymatic assay). It was found to be inactive (IC50>40 µM) toward other protein lysine and arginine methyltransferases, such as SET7/9 (aH3K4 PKMT), SET8/PreSET7 (aH4K20 PKMT), and PRMT3 in the ECSD assays as well as JMJD2E with >1000-fold selectivity. A cell-permeable, quinazoline analog that potently and selectively inhibits PKMT G9a (IC50 = 6 nM and 9 nM in two biochemical assays for CLOT and ECSD, respectively, and Ki = 63 pM, which is approximately 250-fold more potent than a closely-related analog, BIX01294 (Cat. No. 382190)). It inhibits GLP with reduced potency (15 nM) and is found to be inactive (IC50 >40 µM) toward other protein lysine and arginine methyltransferases, such as SET7/9 (aH3K4 PKMT), SET8/PreSET7 (aH4K20 PKMT), and PRMT3, as well as JMJD2E (>1000-fold selectivity) in ECSD enzymatic assays. It also inhibits H3K9me2 accumulation (IC50 = 11,000 nM) in MDA-MB-231 cells, in comparison to BIX01294 (IC50 = 500 nM).Please note that the molecular weight for this compound is batch-specific due to variable water content.
