Eilatin-containing octahedral ruthenium complexes inhibit HIV-1 replication in CD4+ HeLa cells and in human peripheral blood monocytes with IC50 values of approximately 1 μM. Similar metal complexes that lack eilatin display 15-100-fold lower anti-HIV activities. [Ru(bpy)2"pre-eilatin"]2+, a c omplex that contains a nonplanar analogue of eilatin, shows significantly lower nucleic acid binding and lower anti-HIV activity than eilatin complexes. This result indicates that the extended planar surface presented by eilatin is important for both activities. Rev peptide and ethidium bromide displacement assays are used to probe the nucleic acid affinity and specificity of Λ- and Δ-[Ru(bpy)2eilatin]2+. Two HIV-1 RNA sites are compared and a significant binding preference for the Rev response element over the transactivation response region is found. Simple DNA duplexes show a consistent selectivity for Λ-[Ru(bpy)2eilatin]2+ compared to Δ-[Ru(bpy)2eilatin]2+, while RNAs show more diverse enantiomeric selectivities.
