we report a new class of drug-like low molecular weight inhibitors of the lectin LecB with nanomolar affinities and excellent receptor binding kinetics and thermodynamics. This class of glycomimetic inhibitors efficiently blocked biofilm formation of P. aeruginosa in vitro while the natural monovalent carbohydrate ligands failed. Furthermore, excellent selectivity and pharmacokinetic properties were
机会性革兰氏阴性菌铜绿假单胞菌是免疫功能低下患者和囊性纤维化患者感染的主要病原体。它能够从浮游生物转变为聚集体,形成所谓的生物膜,是抗菌素耐药性的前线机制。细菌碳水化合物结合蛋白 LecB 是生物膜形成不可或缺的组成部分。在这里,我们报告了一类新的类药物低分子量凝集素 LecB 抑制剂,具有纳摩尔亲和力和优异的受体结合动力学和热力学。这类糖模拟抑制剂在体外有效阻断铜绿假单胞菌的生物膜形成,而天然单价碳水化合物配体则失效。此外,还实现了优异的选择性和药代动力学特性。尤其,
