From compound library screening using an HCV NS5B RNA-dependent RNA polymerase enzymatic assay, we identified a pteridine hit compound with an IC50 of 15 μM. Our SAR studies were focused on the different groups at the 6- and 7-positions, substitutions at the 4-position, and replacement of N1 or N3 with carbon in the pteridine ring. We found that NH or OH at 4-position is critical for the inhibitory activity. Furthermore, a hydrophobic substituent at the 4-position may help compounds permeate through the cell membrane.

7-Phenyl, 7-(p-methoxyphenyl)-, 7-methyl-, 7-t-butyl-, 6,7-diphenyl-, 6,7-dimethyl- and 2-phenylpteridine are converted in good yields into their respective 4-amino compounds, when they are dissolved in liquid ammonia (-40 deg) and potassium permanganate
