bound in the previously reported active site, utilising a novelbindingmode. This provides potential for further optimisation. The benzomorpholinone was also found to bind in a similar region. Using an X‐ray crystallography/structure‐based design approach, the benzomorpholinone series was further optimised, increasing activity against T. brucei NMT by >1000‐fold. A series of trypanocidal compounds were
来自布氏锥虫的N-肉豆蔻酰转移酶(NMT)已在化学和生物学上被证实是人类非洲锥虫病的潜在药物靶点。我们之前报道了一些基于吡唑磺酰胺系列的非常有效的化合物的开发,这些化合物源自高通量筛选。在此,我们描述了在屏幕中也发现的噻唑烷酮和苯并吗啉支架的工作。大利什曼原虫中噻唑烷酮的 X 射线晶体结构NMT 利用一种新的结合模式显示了该化合物结合在先前报道的活性位点中。这提供了进一步优化的潜力。苯并吗啉酮也被发现在类似的区域结合。使用基于 X 射线晶体学/结构的设计方法,进一步优化了苯并吗啉酮系列,将抗布氏锥虫NMT 的活性提高了 1000 倍以上。确定了一系列具有合适体外 DMPK 特性的杀锥虫化合物,包括用于进一步开发的 CNS 暴露。需要进一步的工作来提高对人类 NMT 同种型的选择性和对布氏锥虫的活性。
