Sitagliptin (MK-0431) phosphate (Standard) is the analytical standard of Sitagliptin phosphate (HY-13749A). This product is intended for research and analytical applications. Sitagliptin phosphate is an orally active and highly selective DPP4 inhibitor with an IC₅₀ value of 19 nM. Sitagliptin phosphate 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 phosphate 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 phosphate shows protective effects on pancreatic islet grafts in 1-type diabetes models. Sitagliptin phosphate can be used for the study of 1-type and 2-type diabetes.
