metallo-β-lactamase (MBL) and serine-β-lactamase (SBL) medicated β-lactam resistance gives rise to an urgent need for the development of new dual-action MBL/SBL inhibitors. Application of a pharmacophore fusion strategy led to the identification of (2'S)-(1-(3'-mercapto-2'-methylpropanamido)methyl)boronic acid (MS01) as a new dual-action inhibitor, which manifests broad-spectrum inhibition to representative MBL/SBL
细菌性病原体获得的金属β-内酰胺酶(MBL)和丝氨酸-β-内酰胺酶(SBL)加药的β-内酰胺耐药性的出现和扩散,迫切需要开发新型的双重作用MBL / SBL抑制剂。药效团融合策略的应用导致鉴定出(2'S)-(1-(3'-巯基-2'-甲基丙酰胺基)甲基)硼酸(MS01)作为新型双作用抑制剂,具有广谱抑制作用代表MBL / SBL酶,包括广泛的VIM-2和KPC-2。在VIM-2:MS01和KPC-2:MS01复杂结构的指导下,进一步的结构优化产生了新的,更有效的双作用抑制剂。选择性研究表明,该抑制剂对人血管紧张素转化酶2没有明显的抑制作用,并且在大肠杆菌中对丝氨酸水解酶具有选择性。基于活性的探针TAMRA-FP标记的大肠杆菌和人HEK293T细胞。而且,该抑制剂显示出美罗培南针对MBL-或SBL-阳性临床分离株的功效增强,而没有明显的细胞毒性。这项工作将有助于开发针对MBL / SBL酶的新型临床有用的双作用抑制剂。
