Charged Propargyl-Linked Antifolates Reveal Mechanisms of Antifolate Resistance and Inhibit Trimethoprim-Resistant MRSA Strains Possessing Clinically Relevant Mutations

16 Jun 2016

Abstract excerpt

Drug-resistant enzymes must balance catalytic function with inhibitor destabilization to provide a fitness advantage. This sensitive balance, often involving very subtle structural changes, must be achieved through a selection process involving a minimal number of eligible point mutations. As part of a program to design propargyl-linked antifolates (PLAs) against trimethoprim-resistant dihydrofolate reductase...
