Inhibitor of euchromatic histone lysine methyltransferase 1;Inhibitor of euchromatic histone lysine methyltransferase 2
Product Description
Description UNC0638 is a potent, selective and cell-penetrant chemical probe for G9a and GLP histone methyltransferase with IC50 of <15 nM and 19 nM, respectively, shows selectivity over a wide range of epigenetic and non-epigenetic targets. UNC0638 has anti-viral activities. Application In MDA-MB-231 cells, in a concentration-dependent manner, exposure to UNC0638 for 48 h reduced H3K9me2 levels with an IC50 value of 81 ± 9 nM. Cellular levels of H3K9me2 were progressively reduced from 1 d to 4 d exposure to UNC0638 at the concentrations of 80 nM (IC50), 250 nM (IC90) and 500 nM (2 × IC90). The reductions of H3K9me2 levels with 250 nM and 500 nM treatments after 4 d were equal or very close to that of G9a and GLP knockdown cells. The effects of UNC0638 were long-lasting. In cells with 2 d exposure to UNC0638, levels of H3K9me2 remained low after washout of compound followed by 2 d incubation without the inhibitor.
