2OPH - PubMed Abstract:
A novel series of 4-aminophenylalanine and 4-aminocyclohexylalanine derivatives were designed and evaluated as inhibitors of dipeptidyl peptidase IV (DPP-4). The phenylalanine series afforded compounds such as 10 that were potent and selective (DPP-4, IC(50)=28nM), but exhibited limited oral bioavailability. The corresponding cyclohexylalanine derivatives such as 25 afforded improved PK exposure and efficacy in a murine OGTT experiment. The X-ray crystal structure of 25 bound to the DPP-4 active site is presented.
