Abstract:
Peptides derived from the interfacial region of dimeric HIV-1 integrase were evaluated as inhibitors of integrase's 3'-endonuclease activity. Three peptides were found to be moderately potent inhibitors with IC(50) values in the low micromolar range. The mode of inhibition was probed through protein crosslinking experiments. Active interfacial peptides were found to inhibit crosslinking of the dimeric form of integrase. Interfacial peptides that were poor inhibitors had no effect on integrase crosslinking.
