Summary
CPTH2 is a potent histone acetyltransferase (HAT) inhibitor. CPTH2 selectively inhibits the acetylation of histone H3 by Gcn5 . CPTH2 induces apoptosis and decreases the invasiveness of a clear cell renal carcinoma (ccRCC) cell line through the inhibition of acetyltransferase p300 (KAT3B) [1] [2] .

In Vitro
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
[1]
.
CPTH2 (100 μM; 12 or 48 hours) causes a comparable drop of the activity in both cell lines
[1]
.
CPTH2 (100 μM; 48 hours) produces a drastic increase in apoptotic/dead cell population after 48 h
[1]
.
CPTH2 (100 μM; 12, 24, 48 hours) shows a reduced acetylation of both global AcH3 histone and H3AcK18
[1]
.
CPTH2 (100 μM; 24, 48 hours) is capable to counteract invasion and migration of ccRCC-786-O cells in culture
[1]
.
CPTH2 (0.2, 0.5, 1 mM) inhibits the growth of a GCN5 deleted strain and a single catalytic mutant E173H
[2]
.
CPTH2 (0.6, 0.8 mM; for 24 hours) inhibits histone H3 acetylation in yeast cell cultures
[2]
.
CPTH2 inhibits the Gcn5p dependent functional network
[2]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
