Abstract:
Corticotropin releasing factor (CRF) family peptides have an important role in the control of food intake. We investigated the effects of CRF family peptides on food intake and body weight gain in mice. Of the CRF family peptides, including CRF, urocortin1 (Ucn1), urocortin2 (Ucn2) and urocortin3 (Ucn3), peripherally administered Ucn1 was shown to have the most potent inhibitory effect on the food intake and body weight gain of both lean and high fat fed obese mice. In addition, repeated administration of Ucn1 lowered blood glucose and acylated ghrelin, and decreased the visceral fat weight of high fat fed obese mice.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
Separation of the aromatic...

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...
Drug-Receptor Interaction: Agonist
Agonists can bind to receptors in different ways. Some agonists bind directly to the receptor's active site, mimicking the endogenous ligand's action.
