| Hazard Information | Back Directory | [Description]
Gcn5 is a chromatin modifying factor whose HAT activity is required to acetylate histone H3 lysine 9 (K9) and K14, which facilitates transcription elongation by relaxing nucleosomes. CPTH2 inhibits the HAT activity of Gcn5 both in vitro and in vivo, reducing histone H3K14 acetylation at a concentration of 0.8 mM. It is a useful tool to study the impact of Gcn5-dependent acetylation in various biological systems and recently has been used to control the replication of human adenovirus. | [Uses]
CPTH2 hydrochloride is a potent histone acetyltransferase (HAT) inhibitor. CPTH2 hydrochloride selectively inhibits the acetylation of histone H3 by Gcn5. CPTH2 hydrochloride induces apoptosis and decreases the invasiveness of a clear cell renal carcinoma (ccRCC) cell line through the inhibition of acetyltransferase p300 (KAT3B)[1][2]. | [IC 50]
