Medchemexpress LLC Sitagliptin phosphate monohydrate | 654671-77-9 | 99.8% | 523.32 | 1 ML
Sitagliptin phosphate monohydrate, also known as MK-0431, is an orally active and highly selective DPP4 inhibitor. It works by blocking the degradation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP), thereby increasing active incretin levels. This compound can also directly stimulate GLP-1 secretion by intestinal L cells through activation of the cAMP/PKA and ERK1/2 pathways, independently of DPP-4. It exhibits protective effects on pancreatic islet grafts in type 1 diabetes models and is used for studying both type 1 and type 2 diabetes.
- Orally active and highly selective DPP4 inhibitor.
- Blocks degradation of GLP-1 and GIP.
- Increases active incretin levels.
- Directly stimulates GLP-1 secretion.
- Protective effects on pancreatic islet grafts.
- Used for studying type 1 and type 2 diabetes.
