    Semaglutide-d8 tetraTFA 99.87%
    Semaglutide-d8 tetraTFA is the deuterium labeled Semaglutide (HY-114118). Semaglutide is a long-acting, selective, competitive GLP-1R agonist that can penetrate the blood-brain barrier. After activating GLP-1R, Semaglutide promotes insulin secretion, inhibits gastric emptying and appetite, and at the same time enhances autophagy, inhibits oxidative stress and apoptosis. Semaglutide also regulates mitochondrial function and lipid metabolism (such as reducing de novo lipogenesis in the liver). Semaglutide has activities such as lowering blood sugar, reducing weight, neuroprotection (such as improving motor function in Parkinson's disease models, reducing α-synuclein aggregation) and improving hepatic steatosis. Semaglutide can be used for the study of neurodegenerative diseases and liver diseases such as type 2 diabetes, obesity, Parkinson's disease, metabolic associated fatty liver disease (MASLD), and cancer.
