Sitagliptin N-sulfate is a phase II metabolite of the dipeptidyl peptidase 4 (DPP-4) inhibitor (-)-sitagliptin . Sitagliptin N-sulfate is formed via sulfation and has been found in rat bile following oral administration of (-)-sitagliptin.
(-)-Sitagliptin carbamoyl glucuronide is a minor phase II metabolite of the dipeptidyl peptidase 4 (DPP-4) inhibitor (-)-sitagliptin . (-)-Sitagliptin carbamoyl glucuronide is formed by N-carbamoyl glucuronidation and has been found in rat and dog plasma following administration of (-)-sitagliptin.
(S)-Sitagliptin phosphate, the less active S-enantiomer of Sitagliptin phosphate, is a high-potency inhibitor of DPP4. It exhibits an IC50 of 19 nM in Caco-2 cell extracts.
Metformin hydrochloride mixture with sitagliptin phosphate is an AMP-activated protein kinase stimulant. It is also a CD26 antigen inhibitor, Gluconeogenesis inhibitor, and Glucose modulator.
AS2575959 is a novel GPR40 agonist, exhibiting glucose metabolism improvement and synergistic effect with sitagliptin on insulin and incretin secretion.
