Аннотация:A new series of potential nonnucleoside inhibitors of HIV-1 reverse transcriptase (NNRTIs) based on the carbocyclic 5'-nor-uracil scaffold were designed and synthesized. Three different aspects of the scaffold were investigated: the effects of adding a linker between the carbocyclic and phenyl fragments, introduction of different substituents on the benzoyl residue and replacing the central carbocyclic ring with a benzyl group. Analogues of 2',3'-dideoxy-2',3'-didehydro-5'-nor-uridine, bearing 3,5-dichloro- or 3,5-dimethylbenzoyl groups, showed inhibitory activity against HIV-RT wild-type (IC50 5-10 mu M) and mutants L100I (IC50 1.2-2.1 mu M) and K103N (IC50 8-17 mu M).
