Abstract:

This project is concerned with the synthesis of suicide inhibitors of reverse transcriptase. This is a key enzyme in replication of HIV, the causative agent of AIDS. A suicide substrate contains a latent reactive group which becomes activated only as a consequence of the normal catalytic activity of the target enzyme and irreversibly inactivates it. Suicide substrates are thus inherently selective and have less side effects when used as drugs. We have synthesized over 40 compounds with these potentialities and screened them for antiviral activity in tissue culture. A number of active compounds, including a new class, the nucleoside spiroxiranes, have been identified which inhibit viral replication in cell culture. These compounds do not inhibit normal cell growth as shown by their favorable therapeutic index on lymphocyte cytotoxicity assays and because of their novel properties, show considerable promise as a new generation of antivirals.
