Penicillin-binding proteins (PBPs) catalyze the final stages for peptidoglycan cell-wall bio-synthesis. Mutations in PBP2a subunit can attenuate β-lactam antibiotic activity, resulting unimpeded formation and methicillin-resistant Staphylococcus aureus (MRSA). A double mutation (i.e., N146K E150K) is resistant to inhibitors; however, (E)-3-(2-(4-cyanostyryl)-4-oxoquinazolin-3(4H)-yl) benzoic acid (QNZ), a heterocyclic devoid of ring, interacts non-covalently with allosteric site inhibits PBP...
