Forty-eight heterocyclic amino acid trimers, analogues of distamycin, with a number of features that enhance lipophilicity are described. They contain alkyl or cycloalkyl groups larger than methyl; some are N-terminated by acetamide or methoxybenzamide and are C-terminated by dimethylaminopropyl or aliphatic heterocylic aminopropyl substituents. The ability of these compounds to bind principally to
描述了四十八个杂环氨基酸三聚体,它是二霉素的类似物,具有许多增强亲脂性的特征。它们含有比甲基大的烷基或环烷基;一些被乙酰胺或甲氧基苯甲酰胺N端基,并且被二甲氨基丙基或脂族杂环甲基氨基丙基取代基C端基。使用毛细管区带电泳已经评估了这些化合物主要结合至DNA AT束的能力。几种化合物,特别是那些含有噻唑的化合物,显示出对关键生物如MRSA和白色念珠菌的显着抗菌活性。而且,这些化合物对几种哺乳动物细胞系具有低毒性。
