Novel HCV NS5B polymerase inhibitors derived from 4-(1′,1′-dioxo-1′,4′-dihydro-1′λ6-benzo[1′,2′,4′]thiadiazin-3′-yl)-5-hydroxy-2H-pyridazin-3-ones. Part 2: Variation of the 2- and 6-pyridazinone substituents
摘要:
5-Hydroxy-3(2H)-pyridazinone derivatives were investigated as inhibitors of genotype 1 HCV NS5B polymerase. The structure-activity relationship (SAR) associated with variation of the pyridazinone 2- and 6-substituents is discussed. The synthesis and metabolic stability of this new class of compounds are also described. (c) 2008 Elsevier Ltd. All rights reserved.
