CBP/p300-IN-19 hydrochloride (compound 29) shows antiproliferative activity with EC50s of 5.3, 8.5, 6.2, 4.4, 1.2, 4.3, 3.6, 8.7, 6.4 µM for MCF-7, MDA-MB231, LNCaP, PC-3, PANC-1, MDA-PANC-28, Molm-13, MV4;11, RPMI-8226 cells, respectively[1]. CBP/p300-IN-19 hydrochloride (0, 5, 10 µM; 12 h) dose-dependenly inhibits the acetylation of H3K18, H3K9 and K27[1]. Western Blot Analysis[1] Cell Line: Kasumi-1 leukemia cells Concentration: 0, 5, 10 µM Incubation Time: 12 h Result: Dose-dependently inhibited the acetylation of H3K18, H3K9 and K27.
