Synthesis, Antimicrobial and β-Lactamase Enzyme Inhibition Activity of Some New Tetrazole Containing Maleamic and Phthaleamic Acid Derivatives

Abstract

In the present study, two series of tetrazole containing maleamic (5a-h) and phthaleamic acid (5i-l) derivatives were synthesized and evaluated for their antimicrobial and β-lactamase enzyme inhibition activities. The synthesized compounds were characterized by IR, 1H NMR and 13C NMR spectral techniques. Among the screened compounds, the compound 5c, 5d, 5e, 5f, 5g and 5h have shown good antimicrobial activity. We further performed exploratory β-lactamase enzyme inhibitors studies on β-lactamase.
