Biological Activity for Glibenclamide

Glibenclamide is an ATP-dependent K+ channel (Kir6, KATP) and CFTR Cl- channel blocker. Inhibits Kir6 currents in the pancreas, causing an increase in intracellular Ca2+ and insulin secretion. Inhibits recombinant CFTR Cl- channels with an IC50 of 20 μM.

Glibenclamide prolongs action potential duration in LPS-treated cardiomyocytes.
By Anonymous on 01/22/2019
Assay Type: In Vitro
Species: Other
Cell Line/Tissue: Ventricular cardiomyocytes

Primary guinea pig ventricular cardiomyocytes were incubated with LPS for 6-10 h. Cells were patched and stimulated at a 1 Hz frequency. Action potentials were recorded before and after glibenclamide (5 microM) containing normal tyrode solution. Glibenclamide prolonged action potential duration in LPS-treated cardiomyocytes; indicating role of KATP channels.

Glibenclamide was used to study combination drug effect with B blockers.
By Anonymous on 10/29/2018
Assay Type: In Vivo
Species: Mouse

Glibenclamide was used in our lab to study combination drug effect. Beta blocker and glibenclamide was administered in combination and separately to study their pattern of action over blood glucose level.
