small molecule inhibitor to the hydrophobic region of the membrane-bound bacterialcellwallsynthesis enzyme and the plasma membrane. In the present study, a total of 20 new amphiphilic compounds were systematically designed and the relationship between molecular hydrophobicity and the antibacterial activity by targeting at PGT was demonstrated. The in vitro lipid II transglycosylation inhibitory effects
Moenomycin A是著名的肽聚糖糖基转移酶(PGT)天然产物抑制剂,是一种两亲性大分子,分子量为1583 g / mol,作为药物的生物利用度相对较差。在寻找针对该酶的具有高抑制能力的小分子配体时,我们发现向细菌PGT的基于伊斯汀的抑制剂中添加疏水基团可显着改善其对酶的抑制作用以及其抗菌活性。酶促抑制作用的改善可归因于小分子抑制剂与膜结合细菌细胞壁合成酶和质膜的疏水区更好的结合。在目前的研究中,总共系统地设计了20种新的两亲化合物,并证明了针对PGT的分子疏水性与抗菌活性之间的关系。的研究了化合物II对脂质体E. coli PBP1b和MIC的体外脂质II转糖基化抑制作用(IC 50)。优化的结果包括对MSSA,MRSA 6微克/毫升的MIC值,枯草芽孢杆菌和12微克/ mL的大肠杆菌用靛红衍生物得到5米其具有335克/摩尔的分子量。
