  New acrylamide-sulfisoxazole conjugates as dihydropteroate synthase inhibitors

  摘要：

  New functionalized acrylamide derivatives bearing sulfisoxazole moiety were designed to target bacterial di-hydropteroate synthase (DHPS). The in vitro antimicrobial activities of these compounds were assessed. The E-configuration of compound 5b was proved by single crystal X-ray analysis. Compounds 5g and 5h displayed double the activity of ampicillin against B. subtilis. Also, 5h was two times more active than gentamycin against E. coli. Interestingly, compounds 5f-g, 7c, 8a, 8c exhibited two folds the potency of amphotericin B against S. racemosum while 5h displayed three folds the activity of amphotericin B against S. racemosum. Most of the synthesized compounds showed superior activities to the parent sulfisoxazole and were non-toxic to normal cells. DHPS is confirmed to be a putative target for our compounds via antagonizing their antibacterial activity by the folate precursor (p-aminobenzoic acid) and product (methionine) on E. coli ATCC 25922. Docking experiments against DHPS rationalized the observed antibacterial activity. Additionally, compound 5g was evaluated as a selective targeting vector for Tc-99m that showed a remarkable uptake and targeting ability towards the infection site that was induced in mice.
