AMPs remains the greatest challenge in their transformation into therapeutics. Herein, we synthesized Fmoc-triazine amino acids that differ from each other by anchoring either cationic or hydrophobic residues. These unnatural amino acids were adopted for solid-phase peptide synthesis (SPPS) to synthesize a series of amphipathic antimicrobial peptidomimetics. From the antimicrobial screening, we found
为了对抗不断增长的抗菌素耐药性,具有独特作用方式的抗菌肽(
AMPs)的开发被认为是一种有吸引力的策略。然而,
AMPs的蛋白
水解降解仍然是其向治疗剂转化的最大挑战。在本文中,我们合成了通过锚定阳离子或疏
水残基而彼此不同的Fmoc-三嗪
氨基酸。这些非天然
氨基酸被用于固相肽合成(
SPPS),以合成一系列两亲性抗菌
肽模拟物。从抗菌素筛选中,我们发现三聚体BJK-4是最有效的短抗菌
肽模拟物,没有显示溶血活性,并且显示出增强的蛋白
水解稳定性。而且,
