  Optimization of Potent Inhibitors of P. falciparum Dihydroorotate Dehydrogenase for the Treatment of Malaria

  摘要：

  Inhibition of dihydroorotate dehydrogenase (DHODH) for P. falciparum potentially represents a new treatment option for malaria, since DHODH catalyzes the rate-limiting step in the pyrimidine biosynthetic pathway and P. falciparum is unable to salvage pyrimidines and must rely on de novo biosynthesis for survival. We report herein the synthesis and structure-activity relationship of a series of 5-(2-methylbenzimidazol-1-yl)-N-alkylthiophene-2-carboxamides that are potent inhibitors against PfDHODH but do not inhibit the human enzyme. On the basis of efficacy observed in three mouse models of malaria, acceptable safety pharmacology risk assessment and safety toxicology profile in rodents, lack of potential drug-drug interactions, acceptable ADME/pharmacokinetic profile, and projected human dose, 5-(4-cyano-2-methyl-1H-benzo[d]imidazol-1-yl)-N-cyclopropylthiophene-2-carboxamide 2q was identified as a potential drug development candidate.

  Inhibitors of dihydroorotate dehydrogenase (DHODH) for the Plasmodium enzyme have been identified and characterized. The inhibitors have high specificity, submicromolar efficacy against cultured parasite strains, exhibit drug-like properties, and are not overtly cytotoxic.

  已经鉴定和表征了针对疟原虫酶的脱氢脱氧尿嘧啶酸脱氢酶（DHODH）抑制剂。这些抑制剂具有高度特异性，在培养的寄生虫株中具有亚微摩尔效力，具有类似药物的特性，并且不明显细胞毒性。

  Methionine aminopeptidase (MetAP) is a promising target to develop novel antibiotics, because all bacteria express MetAP from a single gene that carries out the essential function of removing N-terminal methionine from nascent proteins. Divalent metal ions play a critical role in the catalysis, and there is an urgent need to define the actual metal used by MetAP in bacterial cells. By high throughput screening, we identified a novel class of catechol-containing MetAP inhibitors that display selectivity for the Fe(II)-form of MetAP. X-ray structure revealed that the inhibitor binds to MetAP at the active site with the catechol coordinating to the metal ions. Importantly, some of the inhibitors showed antibacterial activity at low micromolar concentration on Gram-positive and Gram-negative bacteria. Our data indicate that Fe(II) is the likely metal used by MetAP in the cellular environment, and MetAP inhibitors need to inhibit this metalloform of MetAP effectively to be therapeutically useful.
