N2 - The design and selection of a combinatorial library of pyrido[2,3-d]pyrimidin-7(8H)-ones (4) has allowed the synthesis of 121 compounds, using known and new synthetic methodologies, and the evaluation of the inhibitory activity against hepatitis C virus (HCV) genotype 1b replicon. Among these compounds, 21{4,10} and 24{2,10} presented very high activities [EC50 = 0.027 μM (CC50 = 5.3 μM) and EC50 = 0.034 μM (CC50 = 13.5 μM), respectively] and high selectivity indexes, 196 and 397. These values are similar to the EC50 reported for sofosbuvir (2) (0.048 μM) using a similar methodological approach and the same virus subtype. 21{4,10} and 24{2,10} are obtained through shorter synthetic itineraries than sofosbuvir and 24{2,10} is achiral contrary to sofosbuvir which presents 4 stereogenic centers. In silico studies suggest that 21{4,10} and 24{2,10} inhibits NS5B polymerase through allosteric site binding.
