Microwave-assisted optimized transglycosylation reactions were used to prepare eleven modified l-3′-azido-2′,3′-dideoxypurine nucleosides. These l-nucleoside analogs were evaluated against HIV and hepatitis B virus. The l-3′-azido-2′,3′-dideoxypurines nucleosides were metabolized to nucleoside 5′-triphosphates in primary human lymphocytes, but exhibited weak or no antiviral activity against HIV-1. The nucleosides were also inactive against HBV in HepG2 cells. Pre-steady-state kinetic experiments demonstrated that the l-3′-azido-2′,3′-dideoxypurine triphosphates could be incorporated by purified HIV-1 reverse transcriptase, although their catalytic efficiency (kpol/Kd) of incorporation was low. Interestingly, a phosphoramidate prodrug of l-3′-azido-2′,3′-dideoxyadenosine exhibited anti-HIV-1 activity without significant toxicity.
