Aryl dihydrouracil derivatives were identified from high throughput screening as potent inhibitors of HCV NS5B polymerase. The aryl dihydrouracil derivatives were shown to be non-competitive with respect to template RNA and elongation nucleotide substrates. They demonstrated genotype 1 specific activity towards HCV NS5B polymerases. Structure activity relationships and genotype specific activities of aryl dihydrouracil derivatives suggested that they bind to the palm initiation nucleotide pocket, a hypothesis which was confirmed by studies with polymerases containing mutations in various inhibitor binding sites. Therefore, aryl dihydrouracil derivatives represent a novel class of palm initiation site inhibitors of HCV NS5B polymerase.
