We investigated the interaction of a highly potent acridine-based tat-antagonist with the TAR RNA of HIV-1. The wild type TAR RNA and three mutants with U-->C23, G x C-->C x G26-39 or G x C-->A x U26-39 substitutions were used as substrates to study the molecular basis of drug-TAR RNA complex formation. Melting temperature and RNase protection experiments reveal that the G x C26-39 pair is a critical element for specific major groove recognition of TAR at the pyrimidine bulge. The results provide a rational basis for future design of optimized tat/TAR inhibitors.
