acetyl-lysine-containing peptides for binding to bromodomains. From crystallographic studies, it has also been shown to closely mimic the acetamide binding motif in several bromodomains, but has not yet been directly pursued as a fragment in bromodomain inhibition. In this paper, we report the elaboration of N-methylpyrrolidone as a potential lead in fragment-based drug design. Firstly, N-methylpyrrolidone
N-甲基吡咯烷酮是一种溶剂分子,已显示与含乙酰赖氨酸的肽竞争与溴结构域的结合。从晶体学研究来看,它也已显示出在多个溴结构域中紧密模拟乙酰胺结合基序,但尚未直接作为溴结构域抑制中的片段进行研究。在本文中,我们报告了N-甲基吡咯烷酮在基于片段的药物设计中作为潜在先导的详细阐述。首先,N-甲基吡咯烷酮被官能化以提供化学精制点。然后,将该部分掺入已报道的溴结构域抑制剂Olinone的类似物中。X射线晶体学分析表明,在溴结构域结合位点,修饰的类似物显示出与奥林酮相当的结合亲和力和结构模拟。
