Fluoro-Olefins as Peptidomimetic Inhibitors of Dipeptidyl Peptidases
摘要:
The feasibility of the fluoro-olefin function as a peptidomimetic group in inhibitors for dipeptidyl peptidase IV and II (DPP IV and DPP II) is investigated by evaluation of N-substituted Gly-Psi[CF=C]pyrrolidines, Gly-Psi[CF=C]piperldines, and Gly-Psi[CF=C](2-cyano)pyrrolidines. Of this later class, the (Z)- and (E)-fluoro-olefin analogues were prepared and chemical stability in comparison with the parent amide was checked. Most of these compounds exhibited a strong binding preference toward DPP II with IC50 values in the low micromolar range, while only low DPP IV inhibitory potential is seen.

Compounds of the formula
where the variables are as defined in the specification inhibit the NS3 protease of flavivirus sych as hepatitis C virus (HCV). The compounds comprise a novel linkage between a heterocyclic P2 unit and those portions of the inhibitor more distal to the nominal cleavage site of the native substrate, which linkage reverses the orientation of peptidic bonds on the distal side relative to those proximal to the cleavage site.
