  Discovery of a 2,4-Diamino-7-aminoalkoxyquinazoline as a Potent and Selective Inhibitor of Histone Lysine Methyltransferase G9a

  摘要：

  SAR exploration of the 2,4-diamino-6,7-dimethoxyquinazoline template led to the discovery of 8 (UNC0224) as it potent and selective G9a inhibitor. A high resolution X-ray crystal structure of the G9a-8 complex, the first cocrystal structure of G9a with a small molecule inhibitor, was obtained. The cocrystal structure validated our binding hypothesis and will enable structure-based design of novel inhibitors. 8 is a useful tool for investigating the biology of G9a and its roles in chromatin remodeling.

  寻找有效的抗疟药物先导：6,7-二甲氧基喹唑啉-2,4-二胺的合成和评价

  摘要：

  众所周知，喹唑啉具有多种药理活性，因此适用于治疗高血压、病毒感染、肿瘤和疟疾。自 2014 年以来，我们已经合成了大约 150 种不同的 6,7-二甲氧基喹唑啉-2,4-二胺，并通过构效关系研究评估了它们的抗疟活性。在这里，我们总结了结果并报告了 6,7-二甲氧基-N 4 -(1-苯乙基)-2-(吡咯烷-1-基)喹唑啉-4-胺 ( 20 , SSJ-717) 的发现，其表现出高抗疟活性作为一种有前途的抗疟药物先导。

  Protein lysine methyltransferase G9a, which catalyzes methylation of lysine 9 of histone H3 (H3K9) and lysine 373 (K373) of p53, is overexpressed in human cancers. Genetic knockdown of G9a inhibits cancer cell growth, and the dimethylation of p53 K373 results in the inactivation of p53. Initial SAR exploration of the 2,4-diamino-6,7-dimethoxyquinazoline template represented by 3a (BIX01294), a selective small molecule inhibitor of G9a and GLP, led to the discovery of 10 (UNC0224) as a potent G9a inhibitor with excellent selectivity. A high resolution X-ray crystal structure of the G9a-10 complex, the first cocrystal structure of G9a with a small molecule inhibitor, was obtained. On the basis of the structural insights revealed by this cocrystal structure, optimization of the 7-dimethylaminopropoxy side chain of 10 resulted in the discovery of 29 (UNC0321) (Morrison K(i) = 63 pM), which is the first G9a inhibitor with picomolar potency and the most potent G9a inhibitor to date.
