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-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].
