The inbuilt 2-N-hydroxy-1-oxo-3-carboxylic acid of isoquinolone was designed as pyrophosphate mimic for hepatitis C NS5B polymerase. Various 2-hydroxy-1-oxo-1,2-dihydroisoquinoline-3-carboxylic acid derivatives 11a-p were synthesized and evaluated as HCV NS5B polymerase inhibitors. Compound 11c exhibited moderate inhibitory potency based on the inorganic pyrophosphate generation (IC50 = 9.5 μM) and based on NTP incorporation by NS5B enzyme (IC50 = 5.9 μM). Compound 11c demonstrated antiviral activity (EC50 = 15.7 μM) and good selectivity in HCV genotype 1b replicon Ava.5 cells. Compound 11c reduced the interaction of NTP to NS5B polymerase. Docking model showed that 11c situated in similar orientation to the bound uridine triphosphate in the active site of NS5B polymerase. As a result, 2-hydroxy-1-oxo-1,2-dihydroisoquinoline-3-carboxylic acid was disclosed as a novel inbuilt β-N-hydroxy-γ-keto-acid pharmacophore for HCV NS5B polymerase inhibitors. In the part of experimental materials, we found many familiar compounds, such as 5,6-Dihydroxy-2-phenylpyrimidine-4-carboxylic acid(cas: 62222-38-2Computed Properties of C11H8N2O4)
5,6-Dihydroxy-2-phenylpyrimidine-4-carboxylic acid(cas: 62222-38-2) belongs to pyrimidine. The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives, including the nucleotides cytosine, thymine and uracil, thiamine (vitamin B1) and alloxan.
