    Abstract:
    Rational conversion of noncontinuous active regions of proteins into a small orally bioavailable molecule is crucial for the discovery of new drugs based on inhibition of protein-protein interactions. We developed a method that utilizes backbone cyclization as an intermediate step for conversion of the CD4 noncontinuous active region into small macrocyclic molecules. We demonstrate that this method is feasible by preparing small inhibitor for human immunodeficiency virus infection. The lead compound, CG-1, proved orally available in the rat model.
