Metallo-β-lactamase inhibitory activity of phthalic acid derivatives

4-Butyl-3-methylphthalic acid was recognized as a metallo-β-lactamase inhibitor. The structure–activity relationship study of substituted phthalic acids afforded 3-phenylphthalic acid derivatives as potent IMP-1 inhibitors. On the other hand, 3-substituted with 4-hydroxyphenyl phthalic acid derivative displayed a potent combination effect with biapenem (BIPM) against Pseudomonas aeruginosa that produce IMP-1.

3-Substituted phthalic acid derivatives showed potent IMP-1 inhibitory activity, moreover these compounds have combination effect with Biapenem against Pseudomonas aeruginosa that produces IMP-1.Figure optionsDownload as PowerPoint slide
