Dipeptidyl Peptidase Control

H-Pro-Val-OH is a deprotonation dipeptide containing proline, which can catalyze the Michael addition reaction of acetone to trans-β-nitrostyrene. H-Pro Val OH can also serve as a substrate for fibroblast enzymes and prolinase, and has potential applications in biochemical analysis.

(2R)-Vildagliptin is the isomer of Vildagliptin (HY-14291), and can be used as an experimental control. Vildagliptin (LAF237) is a potent, stable, selective dipeptidyl peptidase IV (DPP-IV) inhibitor with an IC₅₀ of 3.5 nM in human Caco-2 cells. Vildagliptin possesses excellent oral bioavailability and potent antihyperglycemic activity.

H-Ser-Pro-OH is a dipeptide containing serine and proline, which can serve as a substrate for prolinase I (PD I) and PD II. H-Ser-Pro-OH can also be used for the synthesis of polypeptide.

H-Pro-Lys-OH is a dipeptide containing proline and lysine, which can serve as a substrate for iminodipeptidase (prolinase). H-Pro-Lys-OH can also be used for the synthesis of polypeptides.

Linagliptin methyldimer is an impurity of Linagliptin. Linagliptin is a DPP-IV inhibitor, with IC₅₀ of 1 nM.

H-Pro-Met-OH is a dipeptide containing proline and methionine. H-Pro-Met-OH also serves as a substrate for prolinase and prolyl dipeptidase.

(–)-Sitagliptin carbamoyl glucuronide is a minor metabolite of the dipeptidyl peptidase 4 (DPP-4) inhibitor Sitagliptin (HY-13749).
