Metallo-β-lactamase-IN-7 is a potent inhibitor of VIM -Type metallo-β-lactamase with IC 50 s of 0.019 μM, 13.64 μM, 0.38 μM for VIM-2, VIM-1 and VIM-5, respectively. Metallo-β-lactamase-IN-7 also enhances the antibacterial activity of Meropenem against the Gram-negative bacterial strains [1].

Metallo-β-lactamase-IN-4 (compound 40) is a potent metallo-β-lactamases (MBL) inhibitor with IC 50 values of 0.1 μM for VIM-1, 1.3 μM for NDM-1 and 5.0 μM for IMP-7, respectively [1].

Metallo-β-lactamase-IN-4 (compound 40) is a potent inhibitor of metallo-β-lactamases (MBL) with IC 50 values of 0.5 μM, 2.1 μM, and 3.3 μM for VIM-1, NDM-1 and IMP-7, respectively [1].

β-Lactamase-IN-7 (compound 14) effectively inhibit Klebsiella pneumoniae that is a potent inhibitor of VIM-Type metallo-β-lactamase with Ki values of 1.26 μM and 0.54 μM for VIM-1 and VIM-4, respectively [1].

Metallo-β-lactamase-IN-3 (compound 35) is a potent metallo-β-lactamases (MBL) inhibitor that has the potential to restore the activity of current β-lactam antibiotics and to offer an orthogonal strategy to the discovery of new antibiotics. Metallo-β-lactamase-IN-3 shows high activity against VIM-1 and NDM-1, with IC 50 of 0.6 and 1.0 μM, respectively. Metallo-β-lactamase-IN-3 does not show inhibition of IMP-7 [1].
