Phthalimide Derivatives with Bioactivity Against : Synthesis, Evaluation, and Computational Studies Involving Cytochrome Inhibition

Abstract

We describe herein the design and synthesis of -phenyl phthalimide derivatives with inhibitory activities against (sensitive and resistant strains) in the low micromolar range and noticeable selectivity indices against human cells. The best inhibitor, 4-amino-2-(4-methoxyphenyl)isoindoline-1,3-dione (), showed a slow-acting mechanism similar to that of atovaquone. Enzymatic assay indicated that inhibited cytochrome complex. Molecular docking studies suggested the binding mode of the best hit to Qo site of the cytochrome complex. Our findings suggest that is a promising candidate for hit-to-lead development.
