UNC 0631 is a potent inhibitor of Protein lysine methyltransferase G9a (also known as KMT1C or EHMT2) with the IC50 value of 4nM [1].
UNC 0631 has been revealed to inhibit the G9a in SAHH-coupled with the IC50 of 4nM. Besides, UNC 0631 has been found to be highly potent in reducing H3K9me2 levels in MDA-MB-231 cells with the ICW IC50 of 25nM. In addition, UNC 0631 has been shown the high in vitro potency against G9a and improved lipophilicity. Besides, UNC 0631 has also been reported to have low cell toxicity in MDA-MB-231 cells with the IC50 value of 2.8μM in MTT assay. In different cell lines, UNC 0631 has been demonstrated to potently reduce H3K9me2 levels with the ICW IC50 of 25nM, 18nM, 26nM, 24nM, 51nM, 72nM and 46nM in MDA-MB-231, MCF7, PC3, 22RV1, HCT116 wt, HCT 116 p53 and IMR90 cell lines, respectively [1].
