GIP Agonists are a class of pharmacological agents that activate the receptor for Glucose-dependent Insulinotropic Polypeptide (GIP), a naturally occurring gut hormone also known as gastric inhibitory polypeptide. These synthetic compounds mimic the action of endogenous GIP, which is to enhance glucose-dependent insulin secretion from pancreatic beta cells and promote satiety. Clinically, GIP agonists are utilized in the management of type 2 diabetes and increasingly for weight management due to their potent effects on glucose metabolism and energy balance.
Origin
The term ‘GIP’ was coined after the hormone’s initial discovery in the late 1960s, recognizing its inhibitory effect on gastric acid secretion, though its primary role as an incretin was later established. ‘Agonist’ is derived from the Greek agōnistēs, meaning “contestant” or “actor,” referring to a substance that initiates a physiological response when bound to a receptor. The development of stable, long-acting synthetic GIP agonists represents a significant advance in endocrinology and metabolic medicine.
Mechanism
The mechanism of action begins with the agonist binding to and activating the GIP receptor, which is expressed on pancreatic beta cells and in adipose tissue and the brain. This binding stimulates intracellular signaling pathways, primarily increasing cyclic AMP (cAMP) levels, which potentiates the glucose-dependent release of insulin. Furthermore, GIP receptor activation contributes to reduced appetite via central nervous system effects and may improve lipid metabolism, collectively addressing the core metabolic dysfunctions of insulin resistance and obesity.
