General description

Repaglinide belongs to the meglitinide class, which differs from the glibenclamide by having a bulky B site group instead of A site.

Application

Repaglinide has been used as a ATP-sensitive potassium channel (KATP) inhibitor in breast cancer cell line MDA-MB-231. It has also been used in the preparation of KATP complex to study its interaction using cryo-EM structural analysis.

Biochem/physiol Actions

Repaglinide (RPG) due to its fast-acting effect prevents hypoglycemia. The KATP inhibition by RPG leads to depolarization in pancreatic β cells leading in voltage-gated calcium channel activation triggering insulin release. Repaglinide favors calcein passage and improves the gap junctional intercellular communication (GJIC). Structurally, RPG binds to the ABC transporter sulfonylurea receptor 1 (SUR1) in the transmembrane bundle.
Repaglinide is a potent short-acting insulin secretagogue that acts by closing ATP-sensitive potassium (KATP) channels in the plasma membrane of the pancreatic beta cell.
Repaglinide is a potent short-acting insulin secretagogue that acts by closing ATP-sensitive potassium (KATP) channels in the plasma membrane of the pancreatic beta cell. It represents a new class of insulin secretagogues, structurally unrelated to sulphonylureas, which were developed for the treatment of type 2 diabetes.
