Sitagliptin-d₄ hydrochloride  (Synonyms: MK-0431-d₄ hydrochloride)

Sitagliptin-d₄ hydrochloride is the deuterium labeled Sitagliptin hydrochloride (HY-13749E). Sitagliptin hydrochloride is an orally active and highly selective DPP4 inhibitor with an IC₅₀ value of 19 nM. Sitagliptin hydrochloride blocks the degradation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) by competing inhibition mechanism (Kᵢ = 1 nM), thereby increasing the level of active incretin. Sitagliptin hydrochloride can also directly stimulate the secretion of GLP-1 by intestinal L cells by activating the cAMP/PKA and ERK1/2 pathways, and this effect is independent of DPP-4. Sitagliptin hydrochloride shows protective effects on pancreatic islet grafts in 1-type diabetes models. Sitagliptin hydrochloride can be used for the study of 1-type and 2-type diabetes.

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
