A new metallo-β-lactamase inhibitor which acts as a medicament for inhibiting the inactivation of β-lactam antibiotics and recovering anti-bacterial activities is disclosed. The maleic acid derivatives having the general formula (I) have metallo-β-lactamase inhibiting activities. It is possible to...
The acid anhydride group in both series of copolymers was converted to the corresponding methyl esters in a two-step reaction. The structure of these polymers was established by elemental analysis and by infrared, 1 H-and 13 C-NMR spectroscopy. Addtional characterization of these copolymers were ...
