Mechanism of Action

Targets/IC₅₀/Ki	Potassium channel
In vitro	Glyburide (Glibenclamide), a sulfonylurea which has been shown to block the ATP-modulated potassium channel in insulin-secreting cells, causes concentration-dependent shifts to the right (up to 100-fold) of the IC50 value for BRL 34915 and diazoxide, and at 1 μM, abolishes the relaxation response to minoxidil sulfate. This compound increases the apparent affinity of HDL binding to Scavenger receptor class B type I (SR-BI). It blocks SR-BI-mediated selective lipid uptake and efflux at a potency similar to that for its inhibition of ABCA1 (IC50 approximately 275-300 mM). At 6 mM, it reduces the opening of KATP channels, aggravating Ca2+ loading only when applied to dinitrophenol-pretreated myocytes but not when applied with dinitrophenol treatment. In concentrations of 10-500 nM, it produces a dose-dependent inhibition of the potassium channel openers (PCOs) relaxation time course. It also reverses existing Pinacidil relaxation regardless of the degree of pre-existing relaxation, and is able to produce its blockade regardless of the state of K+ channel activation.
In vivo	S1716 dose-dependently increases urinary Na⁺ excretion with little change in urinary K+ excretion after i.p. administration (10-100 mg/kg) in saline-loaded conscious rats. S1716 (25 mg/kg i.v.) increases Na⁺ excretion 350% during the first hour post-treatment without affecting K+ excretion, glomerular filtration rate, mean arterial pressure or heart rate.
