is an Ambler class B metallo-β-lactamase (MBL) capable of hydrolyzing a broad-spectrum of β-lactam antibiotics. Although the discovery and development of MBL inhibitors continue to be an area of active research, an array of potent, small molecule inhibitors is yet to be fully characterized for VIM-2. In the presented research, a compound library screening approach was used to identify and characterize
VIM-2 是 Ambler B 类金属-β-内酰胺酶 (MBL),能够水解广谱 β-内酰胺抗生素。尽管 MBL 抑制剂的发现和开发仍然是一个活跃的研究领域,但一系列有效的小分子抑制剂尚未完全表征 VIM-2。在本研究中,使用化合物库筛选方法从药理活性化合物库和重点“点击”化学库中识别和表征 VIM-2 抑制剂。由 VIM-2 筛选产生的四种最有效的 VIM-2 抑制剂通过动力学研究进行表征,以确定K i和酶抑制机制。因此,两种先前描述的药物,米托蒽醌(1,4-二羟基-5,8-双([2-([2-羟乙基]氨基)乙基]氨基)-9,10-蒽二酮)和 4-氯汞苯甲酸酸 ( p CMB) 被发现是有活性的,前者作为一种非竞争性抑制剂 ( K i = 钾一世′ = 1.5 ± 0.2 μM),后者作为缓慢可逆或不可逆抑制剂。此外,来自 click 库的两种新型磺酰三唑类似物被鉴定为有效的竞争性 VIM-2
