  摘要：

  From a research program aimed at the design of new chemical entities followed by extensive screening on various models of infectious diseases, an original series of 2-(3-alkoxy-1H-pyrazol-1-yl)pyrimidines endowed with notable antiviral properties were found. Using a whole cell measles virus replication assay, we describe here some aspects of the iterative process that, from 2-(4-benzyl-3-ethoxy-5-methyl-1H-pyrazol-1-yl)pyrimidine, led to 2-(4-(2,6-difluorophenoxy)-3-isopropoxy-5-methyl-1H-pyrazol-1-yl)-5-ethylpyrimidine and a 4000-fold improvement of antiviral activity with a subnanomolar level of inhibition. Moreover, recent precedents in the literature describing antiviral derivatives acting at the level of the de novo pyrimidine biosynthetic pathway led us to determine that the mode of action of this series is based on the inhibition of the cellular dihydroorotate dehydrogenase (DHODH), the fourth enzyme of this pathway. Biochemical studies with recombinant human DHODH led us to measure IC50 as low as 13 nM for the best example of this original series when using 2,3-dimethoxy-5-methyl-6-(3-methyl-2-butenyl)-1,4-benzoquinone (coenzyme Q(1)) as a surrogate for coenzyme Q(10), the cofactor of this enzyme.
