β lactamase in 5

β-Lactamase-IN-5, a β-lactamase inhibitor isolated from compound 720, holds significant potential for studying bacterial infections.

Metallo-β-lactamase-IN-5 (compound 5c) is a powerful inhibitor of metallo-β-lactamases (MBLs). Its inhibitory activity against MBLs NDM-1 and VIM-1 has been demonstrated. With an IC50 value of 45 μg mL, Metallo-β-lactamase-IN-5 effectively inhibits HUVECs. Additionally, when combined with Imipenem, Metallo-β-lactamase-IN-5 exhibits synergistic antimicrobial activity [1].

Metallo-β-lactamase-IN-6 is a highly effective inhibitor of VIM-Type metallo-β-lactamase, demonstrating IC 50 values of 0.56 μM, 29.50 μM, and 5.78 μM for VIM-2, VIM-1, and VIM-5, respectively. In addition, Metallo-β-lactamase-IN-6 exhibits potent synergistic antibacterial properties when combined with Meropenem, particularly against engineered Escherichia coli strains and clinically isolated Pseudomonas aeruginosa carrying the VIM-2 MBL gene [1].

Metallo-β-lactamase-IN-7 是VIM 型金属 β-内酰胺酶的有效抑制剂，其对VIM-2、VIM-1和VIM-5 的IC50值分别为 0.019 μM、13.64 μM 和 0.38 μM。它还可以增强 Meropenem 对革兰氏阴性菌的抗菌活性。
