considerable flexibility in the binding site. We designed a limited study to investigate this flexibility and probe structure-activity relationships; utilizing the Betti reaction, a 36 compound matrix of quinolinol BoNT/A LC inhibitors was developed using three 8-hydroxyquinolines, three heteroaromatic amines, and four substituted benzaldehydes. This study has revealed some of the most effective quinolinol-based
我们最初发现的BoNT / A的8-羟基喹啉抑制剂和其中一种活性较高的对映体的对映异构体的分离/测试表明,其结合位点具有相当大的灵活性。我们设计了一项有限的研究来调查这种灵活性并探讨结构与活性之间的关系。利用Betti反应,使用三种8-羟基喹啉,三种杂芳族胺和四种取代的苯甲醛开发了一种36种喹啉基BoNT / A LC抑制剂的化合物基质。这项研究揭示了迄今为止一些最有效的基于喹啉醇的BoNT / A抑制剂,在离体测定中,有7种化合物的IC 50值⩽1μM和11种在⩽2μM时有效。
