obestatin

Obestatin (rat) acetate is an endogenous ligand of G-protein coupled receptor 39 (GPR39). Obestatin (rat) acetate has anti-inflammatory, anti-myocardial infarction and antioxidant properties. Obestatin (rat) acetate suppresses food intake, inhibits jejunal contraction, and decreases body-weight gain.

Obestatin is a 23 amino acid peptide hormone with a conserved C-terminal glycine residue and amidation site that is formed by cleavage of the ghrelin and obestatin prepropeptide.1It binds to the orphan receptor GPR39 (Kd= 1 nM) and stimulates cAMP production in CHO and HEK293 cells overexpressing human GPR39. Obestatin inhibits contraction of isolated mouse jejunum muscle strips induced by ghrelin .In vivo, obestatin (12.5-1,000 nmol/kg) suppresses food intake in a time- and dose-dependent manner and reduces body weight gain and gastric emptying in mice. Obestatin (0.22 g per animal) also reduces food intake and glucose response without affecting plasma insulin responses in fasted high-fat diet fed mice.2 1.Zhang, J.V., Ren, P.C., Avsian-Kretchmer, O., et al.Obestatin, a peptide encoded by the ghrelin gene, opposes ghrelin's effects on food intakeScience310(5750)996-999(2005) 2.Subasinghage, A.P., Green, B.D., Flatt, P.R., et al.Metabolic and structural properties of human obestatin {1-23} and two fragment peptidesPeptides31(9)1697-1705(2010)

Obestatin (human) is an endogenous ligand for G-protein eurythmic entity 39 formed by shearing of preproghrelin, which inhibits feeding in a dose-dependent manner, and can be used in the study of obesity.

Endogenous peptide that suppresses food intake and body weight-gain

Obestatin(rat) TFA is a cpeptide derived from the Ghrelin gene, consisting of 23 amino acids. This compound modulates physiological processes by suppressing food intake, inhibiting jejunal contraction, and reducing body-weight gain. It functions as an endogenous ligand for G-protein coupled receptor 39 (GPR39). Additionally, Obestatin(rat) TFA exhibits anti-inflammatory, anti-myocardial infarction, and antioxidant activities [1] [2].

Obestatin(human) TFA, an endogenous peptide originating from the same prepropeptide as ghrelin, is known to suppress food intake and reduce weight gain in rats.

Obestatin(11-23)mouse, rat is a polypeptide that regulates energy balance and suppresses appetite by reducing food consumption, body weight, and jejunal contractions in rodents [1].

Glycochenodeoxycholic Acid (Lithocholylglycine) is a glycine conjugate of lithocholic acid, a bile acid. It is increased in livers of mice that are fed diets supplemented with ursadeoxycholic acid. Glycolithocholic acid levels are decreased in lean mice treated with obestatin. Serum glycolithocholic acid levels increase with age in children.
