  Lead Optimization of Aryl and Aralkyl Amine-Based Triazolopyrimidine Inhibitors of Plasmodium falciparum Dihydroorotate Dehydrogenase with Antimalarial Activity in Mice

  摘要：

  Malaria is one of the leading causes of severe infectious disease worldwide; yet, our ability to maintain effective therapy to combat the illness is continually challenged by the emergence of drug resistance. We previously reported identification of a new class of triazolopyrimidine-based Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) inhibitors with antimalarial activity, leading to the discovery of a new lead series and novel target for drug development. Active compounds from the series contained a triazolopyrimidine ring attached to an aromatic group through a bridging nitrogen atom. Herein, we describe systematic efforts to optimize the aromatic functionality with the goal of improving potency and in vivo properties of compounds from the series. These studies led to the identification of two new substituted aniline moieties (4-SF(5)-Ph and 3,5-Di-F-4-CF(3)-Ph), which, when coupled to the triazolopyrimidine ring, showed good plasma exposure and better efficacy in the Plasmodium berghei mouse model of the disease than previously reported compounds from the series.

  Compounds according to Formula (I), Formula (II), Formula (III), Formula (V), Formula (VI), or to Formula (VII), and pharmaceutical compositions of compounds that conform to Formula (IV) or (Formula VIII): where R1 through R33 are prescribed, selectively inhibit P. falciparum dihydroorotate dehydrogenase. Accordingly, a method for preventing and treating malaria attaches to such compounds, as well as to pharmaceutically acceptable salts, solvates, stereoisomers, tautomers, and prodrugs thereof.
