BIX01294

The methylation of lysine residues on histones plays a central role in determining euchromatin structure and gene expression. The histone methyltransferase (HMTase) G9a can mono- or dimethylate lysine 9 on histone 3 (H3), contributing to early embryogenesis, genomic imprinting, and lymphocyte development. BIX01294 (hydrochloride hydrate) is a selective inhibitor of G9a HMTase (IC50 = 1.7 μM). It less effectively inhibits the HMTase G9a-like protein (GLP; IC50 = 38 μM) and has no effect on other known HMTases. BIX01294 has been used in combination with the calcium channel activator BayK8644 to facilitate the generation of induced pluripotent stem cells from somatic cells in vitro.

BIX-01294 是高度选择性的G9a 和GLP 组蛋白甲基转移酶可逆抑制剂。它通过与底物赖氨酸残基 N 端的氨基酸竞争结合来抑制 G9a GLP，可诱导坏死性凋亡和自噬，具有抗肿瘤活性。

BIX-01294 trihydrochloride 是可逆且高度选择性的G9a 和GLP 组蛋白甲基转移酶抑制剂，IC50分别为 1.9 μM 和 0.7 μM。它可诱导坏死性凋亡和自噬，具有抗肿瘤活性。它通过与底物赖氨酸残基 N 端的氨基酸竞争结合来抑制 G9a GLP。

RG108 (N-Phthalyl-L-tryptophan) 是一种非核苷的 DNA 甲基转移酶 (DNMTs) 抑制剂，IC50为115 nM。它阻断 DNA 甲基转移酶的活性位点，可引起抑癌基因的去甲基化和再激活。

AS8351 (NSC51355) 是一种组蛋白去甲基化酶抑制剂，可以诱导人胎儿肺成纤维细胞重编程为功能性心肌细胞。
