4-(pyridin-2-yl)thiazole-2-amine derivatives and their subsequent optimization, guided by structure-based design, to give 8-(1H-pyrazol-3-yl)pyrido[3,4-d]pyrimidin-4(3H)-ones, a series of potent JmjC histone N-methyl lysine demethylase (KDM) inhibitors which bind to Fe(II) in the active site. Substitution from C4 of the pyrazole moiety allows access to the histone peptide substrate binding site; incorporation
我们报告了 N-取代的 4-(pyridin-2-yl)thiazole-2-amine 衍生物的发现及其后续优化,在基于结构的设计指导下,得到 8-(1H-pyrazol-3-yl)pyrido[ 3,4-d]pyrimidin-4(3H)-ones,一系列有效的 JmjC 组蛋白 N-甲基赖氨酸脱甲基酶 (KDM) 抑制剂,与活性位点中的 Fe(II) 结合。吡唑部分的 C4 取代允许进入组蛋白肽底物结合位点;加入构象受限的 4-苯基哌啶接头产生衍生物,例如 54j 和 54k,它们与 KDM4 (JMJD2) 和 KDM5 (JARID1) 亚科去甲基酶具有同等活性,对 KDM2、KDM3 和 KDM6 亚科的代表性样本具有选择性,细胞渗透性在 Caco-2 测定中,对于 54k,
