CPTH2 是一种组蛋白乙酰基转移酶抑制剂。它选择性地抑制Gcn5对组蛋白 H3 的乙酰化，通过抑制乙酰转移酶p300 (KAT3B)诱导凋亡并降低透明细胞肾癌细胞系的侵袭性。

CPTH2 is a histone acetyltransferase inhibitor modulating Gcn5 network.

CPTH2 decreases cell viability, adhesion, and invasiveness in ccRCC cell line 786-O. It shows preferential inhibition for KAT3B-p300 with hypoacetilating effects on histone H3 at specific H3-K18. Immunohistochemical analysis of 70 ccRCC tumor tissues compared with peritumoral normal epithelium showed a statistical significant reduction of p300/H3AcK18 paralleled by an increase of H3AcK14 in G1 grade and an opposed trend during tumor progression to worst grades[1].
