A series of simple heterocyclic HIV-1 protease inhibitors were developed on the basis of size, shape, and electronic complementarity to the active site of the enzyme, The C-2-symmetric heterocycles do not contain a transition-state isostere nor are they active site directed irreversible inhibitors; thus, they represent the success of a new design strategy. The first generation heterocycles inhibit the protease in the micromolar range, whereas control compounds show no bioactivity at the same concentrations.
