早期扩大环状硼酸 β-内酰胺酶抑制剂 vaborbactam 的范围和效力的努力包括一系列 7 元环硼酸盐。对立体异构体的探索和杂原子的掺入允许鉴定具有取代基的全碳环状硼酸盐作为优选的核心结构,显示出对 A 类和 C 类酶的抑制作用。获得了与重要的β-内酰胺酶结合的一种类似物的晶体结构。当在酸性条件下分离时,这些化合物自发形成中性环状酸酐(分子内前药),与开环羧酸盐(9%)相比,其口服生物利用度(52-69%)显着提高。

efforts to broaden the spectrum and potency of cyclic boronic acid β-lactamase inhibitor vaborbactam included a series of 7-memberedring boronates. Exploration of stereoisomers and incorporation of heteroatoms allowed identification of the all-carbon cyclic boronate with substituents trans as the preferred core structure, showing inhibition of Class A and C enzymes.
