体外研究 (In Vitro) | BET bromodomain inhibitor 1 (compound 38; 31.25-125 nM; 24 hours) leads to more pronounced G1-phase cell cycle arrest[1]. BET bromodomain inhibitor 1 (31.25-500 nM; 6 or 24 hours) is highly effective in inducing dose-dependent inhibition on c-Myc expression and upregulation of p21 levels[1]. BET bromodomain inhibitor 1 (31.25-125 nM; 6 hours) robustly reduces the expressions of c-Myc, BCL-2, and CDK6[1]. BET bromodomain inhibitor 1 does not inhibit five cytochrome P450 enzymes (IC50>20 μM)[1]. BET bromodomain inhibitor 1 demonstrates an excellent selectivity for the BET bromodomain family over other bromodomains, with an ~1500-fold selectivity for BRD4(1) over EP300 (IC50=3857 nM)[1]. BET bromodomain inhibitor 1 strongly inhibited the growth of acute myeloid leukemia cell line MV4-11, acute leukemia cell lines Kasumi-1 and RS-4-11, and multiple myeloma cancer cell line MM1.S cells with IC50values of 2.4, 4.8, 17.6 and 15.1 nM, respectively[1].
