Recent X-ray crystallographic determination of the HIV-1 envelope glycoprotein gp41 core structure opened up a new avenue to discover antiviral agents for chemotherapy of HIV-1 infection and AIDS. We have undertaken a systematic study to search for anti-HIV-1 lead compounds targeted to gp41. Using molecular docking techniques to screen a database of 20 000 organic molecules, we found 16 compounds with the best fit for docking into the hydrophobic cavity within the gp41 core and with maximum possible interactions with the target site. Further testing of these compounds by an enzyme-linked immunosorbent assay and virus inhibition assays discerned two compounds (ADS-J1 and ADS-J2) having inhibitory activity at micromolar concentrations on the formation of the gp41 core structure and on HIV-1 infection. These two compounds will be used as leads to design more effective HIV-1 inhibitors targeted to the HIV-1 gp41 core structure.
