and functions of peptides and plays a critical role in interacting with or binding to the target molecules. Herein, based on the previously reported method for macrocyclic glycopeptide synthesis, two series of tyrocidine A glycosylated derivatives (1a–f and 2a–f) were synthesized and evaluated for their antibacterial activities to further study the structure and activity relationships (SAR).

糖基化可以对肽的性质和功能产生多方面的影响,并且在与靶分子相互作用或结合中起关键作用。在此,根据先前报道的大环糖肽合成方法,合成了两个系列的酪氨酸A糖基化衍生物(1a-f和2a-f),并对其抗菌活性进行了评估,以进一步研究其结构和活性关系(SAR)。生物学研究表明,合成的糖基化衍生物对耐甲氧西林的金黄色葡萄球菌和耐万古霉素的肠球菌具有良好的抗菌活性。。SAR研究基于各种聚糖和键联来增强生化特性,从而鉴定出几种有效的抗生素,例如1f,其治疗指数比酪氨酸A大为改善。版权所有©2015欧洲肽协会和John Wiley&Sons ,Ltd.
