Novel Analogues of the Anti-HIV-1 Agent TSAO-T Modified at the 3′-Spiro Moiety

Abstract

Novel TSAO-T analogues, in which the 3′-spiroaminooxatioledioxide moiety has been replaced by other 3′-spiro moieties bearing a NH group at the same position as the 4″-NH₂ of TSAO-T have been prepared and evaluated for their inhibitory effect on HIV replication in cell culture. In contrast to the prototype compound TSAO-T, the novel TSAO derivatives were inactive at subtoxic concentrations.
