Vildagliptin carboxylic acid metabolite is the major metabolite of the dipeptidyl peptidase 4 (DPP-4) inhibitor vildagliptin in humans. Vildagliptin carboxylic acid metabolite has an IC50 value of 477 μM for DPP-4 in human Caco-2 cells. It is formed from hydrolysis of the cyano group on vildagliptin.
Vildagliptin dihydrate (LAF237 dihydrate) is a powerful and stable dipeptidyl peptidase IV (DPP-IV) inhibitor, demonstrating selectivity with an IC50 of 3.5 nM in human Caco-2 cells. This compound exhibits exceptional oral bioavailability and significant antihyperglycemic activity [1].
