title: Inhibition of HIV-1 integrase activity by synthetic peptides derived from the HIV-1 HXB2 Pol region of the viral genome.
abstract: Peptides deriving from the HIV-1 HXB2 Pol gene sequence were evaluated for inhibitory activity against wild-type (WT) and mutant HIV-1 integrase (IN). The most potent peptide corresponding to a region on the reverse transcriptase (RT) subunit of the Pol polyprotein showed IC(50) value of 5 and 2 microM for 3'-processing and strand transfer, respectively. These peptides, and their analogs, may potentially be used in the elucidation of structural and functional epitopes of IN involved in protein-protein and protein-small molecule interactions.
