We would like to report that using computer-aided design tools and x-ray structures of the HIV-1 protease/inhibitor complex, a novel class of nonpeptide cyclic ureas as HIV protease inhibitors has been designed and synthesized. These cyclic ureas are the first subnanomolar Ki nonpeptide and also the first inhibitors to displace the structural water commonly found in the x-ray structures of other complexes. Confirmation of binding was obtained via x-ray structures. Currently DMP323 is undergoing extensive studies including Phase-1 clinical trial. Ki=0.27nM Cell RNA assay IC90=57nM F% oral bioavailability in dog at 5 mg/Kg=37% (diagram: see text).
