Design and synthesis of specific inhibitors of the 3'-processing step of HIV-1 integrase.
The novel dinucleotide 5'-phosphate, [(L,D)-pIsodApdC], discovered in our laboratory, is a strong inhibitor of HIV-1 integrase for both the 3'-processing and the strand transfer steps. The rationale used in this molecular design was that residues immediately upstream of the dinucleotide cleavage site in the 3'-processing step might provide critical recognition/binding sites on integrase. The rationale for the second type of inhibitors was based on the elimination products (linear and cyclic dinucleotides) of 3'-processing. However, while the linear dinucleotide 5'-phosphate (pdGpdT) was active, its cyclic counterpart was inactive against both wild-type and mutant HIV integrase.
