novel antimicrobial agents are urgently required to address this issue. In this report, we describe the solid phase synthesis, characterization, microbiological and toxicological evaluation of a library of ultrashort cationic antimicrobial lipopeptides based on the previously described tetrapeptide amide H‐Orn‐Orn‐Trp‐Trp‐NH2 conjugated with saturated fatty acids which have inherent antimicrobial activity
多药耐药性微生物的日益增多是传染病临床管理中的最大挑战之一。因此,迫切需要新型抗菌剂来解决这个问题。在本报告中,我们描述了基于前述四肽酰胺H-Orn-Orn-Trp-Trp-NH 2的超短阳离子抗菌脂肽库的固相合成,表征,微生物学和毒理学评估与具有固有抗微生物活性的饱和脂肪酸结合。据报道,这些超短阳离子脂肽表现出优异的广谱抗微生物活性,对许多临床上重要的病原细菌和真菌,包括浮游和无柄(生物膜)培养物中的多药耐药性微生物,均表现出优异的抗菌活性。
