金属-β-内酰胺酶 (MBL) 是一个重要的临床问题,因为它们会水解并灭活几乎所有含有 β-内酰胺的抗生素。这些“救生药物”占当代可用抗生素库的 50% 以上。尽管MBL在全球范围内传播,但MBL抑制剂尚未出现在临床试验中。大多数 MBL 抑制剂以锌离子活性位点为目标,其机制各不相同,从三元络合物形成到金属离子剥离。重要的是,机制的差异可能会影响药理学的可逆性、靶点选择性和结构活性关系解释。本文调查了 MBL 抑制剂的机制,并描述了确定抑制机制的方法,以指导未来疗法的开发。
Metallo-β-lactamases (MBLs) are a significant clinical problem because they hydrolyze and inactivate nearly all β-lactam containing antibiotics. These “lifesaving drugs” constitute >50% of the available contemporary antibiotic arsenal. Despite the global spread of MBLs, MBL inhibitors have not yet appeared in clinical trials. Most MBL inhibitors target active site zinc ions and vary in mechanism from ternary complex formation to metal ion stripping. Importantly, differences in mechanism can impact pharmacology in terms of reversibility, target selectivity, and structure activity relationship interpretation. This article surveys the mechanisms of MBL inhibitors and describes methods that determine the mechanism of inhibition to guide development of future therapeutics.
