continues to rise and the availability of antifungal drugs remains a concern, it becomes obvious that the need to bolster the antifungal armamentarium is urgent. Building from our previous findings of tobramycin (TOB) derivatives with antifungal activity, we further investigate the effects of various linkers on the biological activity of these aminoglycosides. Herein, we analyze how thioether, sulfone, triazole
随着与真菌感染有关的威胁继续增加,并且仍然需要关注抗真菌药物的使用,很明显,增强抗真菌武器库的需求迫在眉睫。根据我们先前对具有抗真菌活性的妥布霉素(TOB)衍生物的发现,我们进一步研究了各种接头对这些氨基糖苷类生物活性的影响。本文中,我们分析了硫醚,砜,三唑,酰胺和醚的官能度如何影响烷基化TOB衍生物对22种念珠菌,隐球菌和曲霉菌的抗真菌活性。我们还评估了它们对鼠红细胞的溶血作用和对哺乳动物细胞系的细胞毒性的影响。虽然三唑连接物似乎总体上具有最佳活性,
