A series of 3- or 4-substituted-2-cyanopyrrolidines were synthesized and evaluated as dipeptidyl peptidase IV inhibitors. Dipeptidyl peptidase IV (DPP-IV) inhibitors have attracted attention as potential drugs for use in the treatment of type 2 diabetes because they prevent degradation of glucagon-like peptide-1 (GLP-1) and extend its duration of action. A series of 2-cyanopyrrolidines are among the most potent of DPP-IV inhibitors. We focused our attention on substitutions at the 3- or 4-position of 2-cyanopyrrolidines and synthesized and evaluated various derivatives. Among them, the 4-fluoro derivative was found to exhibit better DPP-IV inhibitory activity and higher plasma drug concentrations after oral administration to rats than the 4-unsubstituted derivative. We report here on the synthesis and biological data of the aforementioned derivatives.

Paragraph 0854, (2019/05/15)
The present disclosure relates to bifunctional compounds of formula (I), which can be used as modulators of targeted ubiquitination. In particular, the present disclosure is directed to compounds which contain on one end a VHL ligand moiety, which binds to the VHL E3 ubiquitin ligase, and on the other end a moiety that binds a target protein such that degradation of the target protein/polypeptide is effectuated. Also disclosed are VHL ligands of formula (III).
