Syntheses of both 2′-amino-2′-ethynyl guanosine and uridine, using an intramolecular aminohydroxylation reaction as the key step, are described. The corresponding 5′-O-triphosphates of the aforementioned nucleosides were obtained and the inhibitory activity was subsequently evaluated against the hepatitis C virus NS5B polymerase.

Paragraph 0224; 0244, (2017/05/06)
The invention provides an antiviral nucleoside phosphoramidate and a pharmaceutical composition and applications thereof. The nucleoside phosphoramidate compound is prepared by connecting nucleoside with phosphate through phosphorus-oxygen bonds. The structural formulas of the nucleoside phosphoramidate compound are represented by a, a1, a2, b, b1, and b2. The invention also discloses stereoisomers, pharmaceutically acceptable salts, hydrates, solvates, or crystals of the nucleoside phosphoramidate compound. The anti-hepatitis C activity of the provided novel nucleoside phosphoramidate is obviously better than that of sofosbuvir used in clinic. On the saccharide ring, the fluorine atoms are replaced by chlorine atoms, and the cytotoxicity of measure cell lines is prominently reduced. By systematically modifying and optimizing the basic groups, saccharide rings, and prodrugs, the anti-hepatitis C activity of partial synthesized compounds is 2 to 10 times higher than that of sofosbuvir. At the same time, the key parts of metabolism are optimized, the metabolism stability and chemical stability of synthesized compounds in plasma are better, compared with those of sofosbuvir.
