GRAPHICAL ABSTRACT ABSTRACT Puromycin is a peptidyl nucleoside endowed with significant antibiotic and anticancer properties, but also with an unfortunate nephrotoxic character that has hampered its use as a chemotherapeutic agent. Since hydrolysis of puromycin's amide to puromycin aminonucleoside is the first metabolic step leading to nephrotoxicity, we designed a 3′-C-hydrazide analog where the nitrogen and
图形摘要摘要嘌呤霉素是一种肽基核苷,具有显着的抗生素和抗癌特性,但也具有不幸的肾毒性,阻碍了其作为化学治疗剂的使用。由于嘌呤霉素酰胺水解为嘌呤霉素氨基核苷是导致肾毒性的第一个代谢步骤,我们设计了一种 3'-C-酰肼类似物,其中嘌呤霉素酰胺羰基周围的氮和碳官能团被反转。由 D-木糖分 11 个步骤合成的标题化合物不能代谢为具有肾毒性的氨基核苷。对表皮葡萄球菌和多药耐药性金黄色葡萄球菌的标题化合物的评估未显示高达 400 μM 浓度的显着抗菌活性。
