describing the discovery and optimization of bromo and extraterminal inhibitors which are selective for the second bromodomain (BD2); these include our own work toward GSK046 (3) and GSK620 (5). This paper describes our approach to mitigating the genotoxicity risk of GSK046 by replacement of the acetamide functionality with a heterocyclic ring. This was followed by a template-hopping and hybridization approach
最近发表了许多报告,描述了对第二个溴结构域(BD2)具有选择性的溴和末端抑制剂的发现和优化。这些包括我们自己对GSK046(3)和GSK620(5)的研究。本文介绍了我们用杂环取代乙酰胺官能团来减轻GSK046遗传毒性风险的方法。随后是在基于结构的药物设计指导下的模板跳跃和杂交方法,以结合其他BD2选择性系列的学习成果,优化酰胺区域的载体,并探索ZA裂隙,从而鉴定出有效的,选择性和可生物利用的化合物28(GSK452),39(GSK737)和36(GSK217)。
