CPTH2 是一种特异性组蛋白乙酰转移酶抑制剂，可在体外和体内调节 Gcn5 网络。

CPTH2 is a specific histone acetyltransferase inhibitor modulating Gcn5 network in vitro and in vivo, inhibits H3 acetylation and induces cell-cycle perturbation and apoptosis in U-937 cells; increases E1A CR3 transactivation of human adenovirus through inhibition of HAT GCN5, also reduces virus yield during infection; induces apoptosis and decreases the invasiveness of a ccRCC cell line through the inhibition of KAT3B.

CPTH2 (100 μM; 12, 24, 48 hours) causes a decrease in cell proliferation after as early as 12 h with a further significant reduction after 48 h stimulation. CPTH2 (100 μM; 12 or 48 hours) causes a comparable drop of the activity in both cell lines. CPTH2 (100 μM; 48 hours) produces a drastic increase in apoptotic/dead cell population after 48 h. CPTH2 (100 μM; 12, 24, 48 hours) shows a reduced acetylation of both global AcH3 histone and H3AcK18. CPTH2 (100 μM; 24, 48 hours) is capable to counteract invasion and migration of ccRCC-786-O cells in culture. CPTH2 (0.2, 0.5, 1 mM) inhibits the growth of a GCN5 deleted strain and a single catalytic mutant E173H. CPTH2 (0.6, 0.8 mM; for 24 hours) inhibits histone H3 acetylation in yeast cell cultures. CPTH2 inhibits the Gcn5p dependent functional network.
