CPTH2 hydrochloride 是有效的组蛋白乙酰基转移酶 (HAT) 抑制剂。CPTH2 hydrochloride 选择性地抑制Gcn5对组蛋白 H3 的乙酰化。CPTH2 hydrochloride 通过抑制乙酰转移酶p300 (KAT3B)诱导凋亡 (apoptosis) 并降低透明细胞肾癌 (ccRCC) 细胞系的侵袭性。
生物活性 | CPTH2 hydrochloride is a potenthistone acetyltransferase(HAT)inhibitor. CPTH2 hydrochloride selectively inhibits the acetylation of histone H3 byGcn5. CPTH2 hydrochloride inducesapoptosisand decreases the invasiveness of a clear cell renal carcinoma (ccRCC) cell line through the inhibition ofacetyltransferase p300 (KAT3B)[1][2]. |

体外研究 (In Vitro) | CPTH2 (100 μM; 12, 24, 48 hours) hydrochloride 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) hydrochloride causes a comparable drop of the activity in both cell lines[1]. CPTH2 (100 μM; 48 hours) hydrochloride produces a drastic increase in apoptotic/dead cell population after 48 h[1]. CPTH2 (100 μM; 12, 24, 48 hours) hydrochloride shows a reduced acetylation of both global AcH3 histone and H3AcK18[1]. CPTH2 (100 μM; 24, 48 hours) hydrochloride is capable to counteract invasion and migration of ccRCC-786-O cells in culture[1]. CPTH2 (0.2, 0.5, 1 mM) hydrochloride inhibits the growth of a GCN5 deleted strain and a single catalytic mutant E173H[2]. CPTH2 (0.6, 0.8 mM; for 24 hours) hydrochloride inhibits histone H3 acetylation in yeast cell cultures[2]. CPTH2 hydrochloride inhibits the Gcn5p dependent functional network[2].
