Inhibitors of HCV NS5B polymerase: synthesis and structure–activity relationships of N-1-heteroalkyl-4-hydroxyquinolon-3-yl-benzothiadiazines
摘要:
N-1-Alkylamino and N-1-alkyloxy-4-hydroxyquinolon-3-yl benzothiadiazines were synthesized and evaluated as inhibitors of genotype 1 HCV polymerase. The N-1-alkyloxy derivatives were not potent inhibitors, however N-1-alkylamino derivatives displayed comparable potency to carbon analogs. Analogs with aliphatic substituents were significantly more potent than those with benzylic substituents against genotype la polymerase. The most potent inhibitors contained small alkyl or carbocyclic substituents and exhibited IC50's of 50-100 and 200-400 nM against genotype 1 b and 1 a HCV polymerase, respectively.

A series of non-nucleoside HCV NS5B polymerase inhibitors based on the N-1-benzyl or N-1-[3-methylbutyl]-4-hydroxy-1,8-naphthyridon-3-yl benzothiadiazine core substituted in the D-ring aromatic moiety have been prepared and evaluated. Aromatic substituents extending from position 7 of the D-ring exhibited excellent potency against both genotypes 1a and 1b. (c) 2006 Elsevier Ltd. All rights reserved.
