A series of novel guanidine-based small molecule inhibitors of inosine monophosphate dehydrogenase (IMPDH) was explored. IMPDH catalyzes the rate determining step in guanine nucleotide biosynthesis and is a target for anticancer, immunosuppressive and antiviral therapy. The synthesis and the structure-activity relationships (SARs), derived from in vitro studies, for this new series of inhibitors is given.

Abstract A novel series of HIV protease inhibitors has been prepared. Replacement of the P2 carbamate of compound 1 [IC50 = 125 nM] with an α-hydroxy amide moiety results in a significant increase in anti-HIV protease activity [e. g., compound 25a; IC50 = 15 nM]. Furthermore, isomers with (R) absolute configuration at the P2 site show greater inhibitory activity than the corresponding (S)-isomers. A proposed binding mode based on molecular modeling is used to rationalize the structure-activity relationships.
