A novel series of compounds, derived from [1,2,3]triazolo[4,5-d]pyrimidines with a guanidyl group or amino group-terminated side chain was designed and synthesized as HIV-1 trans-activator of transcription–trans-activation responsive region (Tat–TAR) interaction inhibitors. Their ability to inhibit Tat–TAR RNA interaction was determined by a Tat-dependent HIV-1 long terminal repeat (LTR)-driven chloramphenicol acetyltransferase (CAT) assay and simian immunodeficiency virus (SIV)-induced syncytium evaluation. The binding of the compounds with TAR RNA was conducted by molecular modeling and capillary electrophoresis (CE) analysis. The results showed that all the compounds could block the Tat–TAR interaction and have antiviral activities.
