MßL-IN-2I is a potent broad-spectrum metallo-β-lactamase (MβL) inhibitor which inhibits the MβLs NDM-1, VIM-2, ImiS, and L1.

β-Lactamase-IN-1 (4-(1,3-dihydroxypropan-2-yl)-6-methoxypyrido[2,3-b]pyrazin-3-one) is a β-Lactamase inhibitor and targets the infection of Neisseria gonorrhoeae.

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].

Cefcanel is a semisynthetic third-generation cephalosporin with antibacterial activity. Cefcanel is active against the species E. coli, K. aerogenes and Proteus mirabilis; H. influenzae and M. catarrhalis has reasonable susceptibility. Cefcanel inhibits 90% of S. aureus strains at 2 µg/ml, irrespective of the presence of a β-lactamase. Cefcanel binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

Metallo-β-lactamase-IN-8 (compound 17) is a potent, reversible and competitive broad-spectrum metallo-β-lactamases (MβLs) inhibitor with antibacterial activity. The IC50 values of Metallo-β-lactamase-IN-8 against L1, ImiS, IMP-1 and VIM-2 are 1.3 μM, 5.7 μM, 9.8 μM, and 9.9 μM, respectively [1].

VIM-2-IN-1 (compound 1dj) is a β-lactamase inhibitor with antibacterial activity. IC50: 48 μM) and New Delhi Metal (NDM-1) (IC50: 231 μM).

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].
