Bromodomain-containing protein 4 (BRD4) is a key epigenetic regulator in cancer; and inhibitors targeting BRD4 exhibit great anticancer activity. By replacing the methyltriazole ring of the BRD4 inhibitor I-BET-762 with an N-methylthiazolidone heterocyclic ring, fifteen novel BRD4 inhibitors I (R = OEt, OH, tert-butylamino, cyclopropylamino, piperidin-1-yl, morpholin-4-yl, etc.) and II were designed and synthesized. Compound I [R = cyclopentylamino] (III) had a hydrophobic acetylcyclopentanyl side chain, showing the most potent BRD4 inhibitory activity in the BRD4-BD1 inhibition assay (IC₅₀ value of 110 nM), and it also significantly suppressed the proliferation of MV-4-11 cells with high BRD4 level (IC₅₀ value of 0.42μM). Furthermore, the potent apoptosis-promoting and G0/G1 cycle-arresting activities of compound III were indicated by flow cytometry. As the downstream-protein of BRD4, c-Myc was in significantly low expression by compound III treatment in a dose-dependent manner. All the findings supported that the novel compound III provided a perspective for developing effective BRD4 inhibitors.
