Biological Activity

IRBM6 (Class I HDAC-IN-6) is a potent, class I selective HDAC inhibitor with EC50 of 50 nM (HeLa cellular), HDAC1/2/3 IC50 of 1.7/2.8/1.1 nM.
IRBM6 weakly inhibits HDAC6 (IC50=177 nM) and is inactive at 5 uM against HDACs 4-7.
IRBM6 showed a potent inhibitory effect on the growth TC-797s and two additional NUT carcinoma (NC) cell lines, PER-403, and 10-15.
IRBM6 induces a transcriptional program of differentiation in NC cells, demonstrated large-scale changes in gene expression that were significantly enriched with differentiation gene sets and depleted of pro-growth gene sets, including those of MYC and E2F targets.
IRBM6 repressed growth and induced differentiation of NUT carcinoma (NC) cells in proportion to inhibition of NUT transcriptional activity.
