among pathogens creates an urgent need to develop new antimicrobial agents. Many reported polycations show high antimicrobial activity along with low hemolytic activity. Unfortunately, most of those molecules remain highly cytotoxic against various mammalian cells. In this work, a systematic study on the impact of triethylene glycol monomethyl ether side groups (short polyethylene glycol (PEG) analog)
病原体中抗生素耐药性的惊人增加导致迫切需要开发新的抗菌剂。许多报道的聚阳离子显示出高抗微生物活性和低溶血活性。不幸的是,这些分子中的大多数仍然对各种哺乳动物细胞具有高度的细胞毒性。在这项工作中,系统研究了三甘醇单甲醚侧基(短聚乙二醇 (PEG) 类似物)对新型两亲紫罗烯的抗菌、溶血和细胞毒性特性的影响。介绍了合成的详细描述,导致定义明确的交替聚合物,其在负责亲水性 (PEG) 和疏水性 (烷基链) 的结构元素上有所不同。金黄色葡萄球菌,包括耐甲氧西林菌株 (MRSA)。此外,还讨论了细菌细胞和荧光标记脂质体的机理研究结果。
