More research effort needs to be invested in antimicrobial drug development to address the increasing threat of multidrug-resistant organisms. The enzyme DHPS has been a validated drug target for over 70 years as the target for the highly successful sulfa drugs. The use of sulfa drugs has been compromised by the widespread presence of resistant organisms(More)
Dihydropteroate synthase (DHPS) is the classical target of the sulfonamide class of antimicrobial agents, whose use has been limited by widespread resistance and pharmacological side effects. We have initiated a structure-based drug design approach for the development of novel DHPS inhibitors that bind to the highly conserved and structured pterin subsite(More)
Dihydropteroate synthase (DHPS) is the validated drug target for sulfonamide antimicrobial therapy. However, due to widespread drug resistance and poor tolerance, the use of sulfonamide antibiotics is now limited. The pterin binding pocket in DHPS is highly conserved and is distinct from the sulfonamide binding site. It therefore represents an attractive(More)
