    A series of HIV protease inhibitors containing a novel (hydroxyethyl)amidosuccinoyl core has been synthesized. These peptidomimetic structures inhibit viral protease activity at low nanomolar concentrations (IC50 < 10 nM for HIV-1 protease). The inhibition constant (Ki) for inhibitor 19 was determined to be 7.5 pM against HIV-1 and 1.2 nM against HIV-2 proteases, respectively. Several compounds (19-24) inhibited HIV-1 replication in cell culture assays with 50% effective concentrations (EC50) = 3.7-35 nM. This series of inhibitors was found to exhibit poor bioavailability (< 10%) in the rat, following oral administration. The synthesis and biological properties of these compounds are discussed. In addition, an X-ray structure of one of these inhibitors (23) in complex with HIV-2 protease provides insight into the binding mode of this novel class of HIV protease inhibitors.
