Compounds and compositions of Formula (I) are described, useful as anti-proliferative agents, and in particular anti-HPV.
Compounds of Formula I: I and their pharmaceutically acceptable salts are useful for the inhibition of HIV reverse transcriptase. The compounds may also be useful for the prophylaxis or treatment of infection by HIV and in the prophylaxis, delay in the onset or progression, and treatment of AIDS. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antiviral agents, immunomodulators, antibiotics or vaccines.
A novel2',3'-dideoxy-2'-α-fluoro-2'-β-C-methyl-6-methoxy guanosine (8) and its phosphoramidate prodrug (1) have been designed and synthesized. Their biological activity was evaluated in both cytotoxicity and cell-based HCV replicon assays. Neither compounds exhibited cytotoxicity up to the highest concentration tested (100 μM) in the Huh-7 cell line. The prodrug (1) displayed nanomolar level antiviral
