A combination of different HIV inhibitors into a single molecular entity is a strategy that is growing in popularity in HIVchemotherapy research. The high levels of resistance elicited by both nucleoside and non-nucleoside reverse transcriptase inhibitors has prompted the design of double-drugs combining these two entities with the aim of addressing the emergence of resistance. The strategy involves combining two different inhibitors into a single chemical entity via a linker, with the aim of improving the physicochemical characteristics of the individual compounds. Linkers may be sub-divided into cleavable and non-cleavable. While the former result in regeneration of the parent drugs of the double-drug once in the cell cytoplasm, the latter type is designed to allow the double-drug to target two active sites in a simultaneous or bifunctional fashion, which are located in close proximity. The linkers have been attached at the C-5, C-5 or N-3 positions of the nucleoside, and in some of the substrates synthesized, a synergistic anti-HIV activity has been observed. This review focuses on the design and synthesis of anti-HIV double-drugs reported to date.
