UNC0638 is a potent and selective inhibitor of G9a and GLP with IC50 values of < 15 nM and 19 ± 1 nM, respectively [1].

GLP forms a heterodimer with G9a. Both G9a and GLP can mono- and dimethylate histone H3 Lys9 (H3K9), and dimethylate Lys373 of p53 and hence inactivate the transcriptional activity of p53 [1].

UNC0638 showed balanced physico and potency aiding cell penetration in vitro, had high potency in cellular assays. It was much less toxic than BIX01294 to cells. 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 (n= 3), which showed considerably higher potency than BIX01294 (IC50= 500 ± 43 nM (n= 3)). In reducing H3K9me2 levels, UNC0638 was of greater maximum effect than BIX01294. This effect is close, but not equal, to the effect on the double knockdown of G9a and GLP via shRNA [1].
