Optimization of Hydantoins as Potent Antimycobacterial Decaprenylphosphoryl-β-d-Ribose Oxidase (DprE1) Inhibitors
摘要:
In search of novel drugs against tuberculosis, we previously discovered and profiled a novel hydantoin-based family that demonstrated highly promising in vitro potency against Mycobacterium. tuberculosis. The compounds were found to be noncovalent inhibitors of DprE1, a subunit of decaprenylphosphoryl-beta-D-ribose-2'-epimerase. This protein, localized in the periplasmic space of the mycobacterial cell wall, was shown to be an essential and vulnerable antimycobacterial drug target. Here, we report the further SAR exploration of this chemical family through more than 80 new analogues. Among these, the most active representatives combined submicromolar cellular potency and nanomolar target affinity with balanced physicochemical properties and low human cytotoxicity. Moreover, we demonstrate in vivo activity in an acute Mtb infection model and provide further proof of DprE1 being the target of the hydantoins. Overall, the hydantoin family of DprE1 inhibitors represents a promising noncovalent lead series for the discovery of novel antituberculosis agents.
