synthesis and inhibitory activities of a series of new 3-piperonylcoumarins, designed as inhibitors of glycosomal glyceraldehyde-3-phosphate dehydrogenase (gGAPDH) from Trypanosoma cruzi. The design was based on the structures of previously identified natural products hits. The most active synthesized derivatives contain heterocyclic rings at position 6. SAR studies, performed by electronic indices methodology
本文介绍了一系列新型3-哌啶香豆素的合成和抑制活性,这些3-哌啶香豆素被设计为克氏锥虫糖体甘油醛-3-磷酸脱氢酶(gGAPDH)的抑制剂。该设计基于先前确定的天然产品的结构。活性最高的合成衍生物在第6位含有杂环。由于生物活性方面的化学取代,通过电子指数方法(EIM)进行的SAR研究将分子分为不同的基团。通过对接进行的分子建模研究表明,与天然命中的油菜籽相比,活性最高的衍生物具有不同的结合模式。此外,香豆素环似乎仅起间隔基团的作用。
