novel class of monocyclic 3‐amino‐β‐lactams to inhibit penicillin‐binding proteins (PBPs) of various (resistant) bacteria was assessed, revealing the potential of α‐benzylidenecarboxylates as interesting leads in the pursuit of novel PBP inhibitors. No deactivation by representative enzymes belonging to the four β‐lactamase classes was observed, while weak inhibition of class C β‐lactamase P99 was demonstrated
作为著名的双环β-内酰胺抗生素的补充,单环类似物可在抵抗耐药细菌的战斗中提供新鲜空气。在此框架下,本研究公开了十一种诺卡汀样对映体纯的2- 3- [2-(2-氨基噻唑-4-基)-2-(甲氧基亚氨基)乙酰胺基]的计算机模拟设计和空前的十步合成方法。从丝氨酸开始的-2-氧杂氮杂环丁烷-1-基}乙酸是容易获得的前体。评估了这类新型的单环3-氨基-β-内酰胺类抑制各种(耐药)细菌的青霉素结合蛋白(PBPs)的能力,揭示了α-亚苄基羧酸盐作为追求新型PBP抑制剂的有趣线索的潜力。 。没有观察到属于四个β-内酰胺酶类别的代表性酶的失活,
