  Structure-Guided Lead Optimization of Triazolopyrimidine-Ring Substituents Identifies Potent Plasmodium falciparum Dihydroorotate Dehydrogenase Inhibitors with Clinical Candidate Potential

  摘要：

  Drug therapy is the mainstay of antimalarial therapy, yet current drugs are threatened by the development of resistance. In an effort to identify new potential antimalarials, we have undertaken a lead optimization program around our previously identified triazolopyrimidine-based series of Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) inhibitors. The X-ray structure of PfDHODH was used to inform the medicinal chemistry program allowing the identification of a potent and selective inhibitor (DSM265) that acts through DHODH inhibition to kill both sensitive and drug resistant strains of the parasite. This compound has similar potency to chloroquine in the humanized SCID mouse P. falciparum model, can be synthesized by a simple route, and rodent pharmaco-kinetic studies demonstrated it has excellent oral bioavailability, a long half-life and low clearance. These studies have identified the first candidate in the triazolopyrimidine series to meet previously established progression criteria for efficacy and ADME properties, justifying further development of this compound toward clinical candidate status.

  Inhibitors of parasitic dihydroorotate dehydrogenase enzyme (DHOD) are candidate therapeutics for treating malaria. Illustrative of such therapeutic agents include the compound: and a triazolopyrimidine class of compounds that conform to Formula IX: and their solvates, stereoisomers, tautomers and pharmaceutically acceptable salts.

• Novel Selective Inhibitor of <i>Leishmania (Leishmania) amazonensis</i> Arginase

  Arginase is a glycosomal enzyme in Leishmania that is involved in polyamine and trypanothione biosynthesis. The central role of arginase in Leishmania (Leishmania) amazonensis was demonstrated by the generation of two mutants: one with an arginase lacking the glycosomal addressing signal and one in which the arginase‐coding gene was knocked out. Both of these mutants exhibited decreased infectivity. Thus, arginase seems to be a potential drug target for Leishmania treatment. In an attempt to search for arginase inhibitors, 29 derivatives of the [1,2,4]triazolo[1,5‐a]pyrimidine system were tested against Leishmania (Leishmania) amazonensis arginase in vitro. The [1,2,4]triazolo[1,5‐a]pyrimidine scaffold containing R1 = CF3 exhibited greater activity against the arginase rather than when the substituent R1 = CH3 in the 2‐position. The novel compound 2‐(5‐methyl‐2‐(trifluoromethyl)‐[1,2,4]triazolo[1,5‐a]pyrimidin‐7‐yl)hydrazinecarbothioamide (30) was the most potent, inhibiting arginase by a non‐competitive mechanism, with the Ki and IC50 values for arginase inhibition estimated to be 17 ± 1 μm and 16.5 ± 0.5 μm, respectively. These results can guide the development of new drugs against leishmaniasis based on [1,2,4]triazolo[1,5‐a]pyrimidine derivatives targeting the arginase enzyme.
