antimicrobial peptides are urgently needed in order to combat the threat posed by the recent increase of resistance to antibiotics. In this paper, we present a new series of antimicrobial peptides, based on the key structural features of the lantibiotic nisin. We have simplified the structure of nisin by conjugating the lipid II-binding motif at the N-terminus of nisin to a series of cationic peptides and peptoids
迫切需要新的抗菌肽设计,以应对近期对抗生素耐药性增加带来的威胁。在本文中,我们基于羊毛硫抗生素乳链菌肽的关键结构特征,提出了一系列新的抗菌肽。我们通过将乳链菌肽N末端的脂质II结合基序缀合到一系列具有已知抗菌作用和成孔特性的阳离子肽和类肽,简化了乳链菌肽的结构。使用亲水性PEG4接头的杂合肽对黄褐微球菌显示出良好的抗菌活性。
