ABSTRACT
Indole derivative 1 interferes with the interaction of the HIV surface protein gp120 with the host cell receptor CD4. The 4-fluoro derivative 2 exhibited markedly enhanced potency and was bioavailable in the rat, dog, and cynomolgus monkey when administered orally as a solution formulation. However, aqueous suspensions of 2 were poorly bioavailable, indicative of dissolution-limited absorption. The 7-azaindole derivative 3, BMS-378806, exhibited improved pharmaceutical properties while retaining the HIV-1 inhibitory profile of 2.
