DCH36_06 is a potent and selective p300/CBP inhibitor with IC₅₀s of 0.6 μM and 3.2 μM for p300 and CBP, respectively. DCH36_06 mediated p300/CBP inhibition leading to hypoacetylation on H3K18 in leukemic cells. Anti-tumor activity^[1].

DCH36_06 (6.7-20 μM; 24-48 hours) treatment arrests cell cycle at G1 phase and induces apotosis in a dose-dependent manner in leukemic cells^[1].
DCH36_06 (5-10 μM; 24 hours) treatment significantly activates the cleavage of pro-caspase 3, pro-caspase 9 and PARP1 at dose-dependent manner^[1].
DCH36_06 shows potent antiproliferative activity against tested leukemia cell lines (CEM, MOLT3, MOLT4, Jurkat, MV4-11, THP-1, RS4; 11, KOPN8, Kasumi-1 and K562 cells) in a dose-dependent manner with IC50 values at single-digit micromolar range^[1].
