描述了80种与二霉素和噻唑类相关的短小沟结合剂的合成和性能。化合物的设计主要基于小沟结合剂和DNA之间的疏水相互作用而增加的亲和力。疏水性芳族头基(包括喹啉基和苯甲酰基衍生物)的引入以及烯烃作为连接剂的引入,导致几种具有MIC的金黄色葡萄球菌的强活性抗菌化合物(对甲氧西林敏感和耐药的菌株)范围为0.1-5 microg mL -1,与许多已建立的抗菌剂相当。还发现针对黑曲霉和白色念珠菌的抗真菌活性为20-50微克mL-1 MIC,再次与已确立的抗真菌药物相当。

A series of 32, structurally diverse MGBs, derived from the natural product distamycin, was evaluated for activity against Trypanosoma brucei brucei. Four compounds have been found to possess significant activity, in the nanomolar range, and represent hits for further optimisation towards novel treatments for Human and Animal African Trypanosomiases. Moreover, SAR indicates that the head group linking moiety is a significant modulator of biological activity. (C) 2016 The Authors. Published by Elsevier Masson SAS.
