- Alomone Labs Carvedilol inhibits Kir3.2 channels expressed in Xenopus oocytes.Application of 300 µM Carvedilol (#C-180, bottom bar) reversibly inhibits Kir3.2 channel currents. Kir3.2 channels were activated by continuous application of high K+ containing solution (top bar) at a holding potential of -80 mV, resulting in a downward deflection of the continuously recorded current trace.

Scientific background Carvedilol is a potent nonselective β1-, β2-, and α1-adrenoceptor antagonist1 with an IC50 of 3.8 µM2. Carvedilol is also a vasodilator with anti-oxidant, anti-inflammatory, anti-fibrotic and anti-proliferative effects. It has “atypical” effects on β-receptors mediated by an interaction with G proteins that leads to down-regulation of receptors in model systems. Experimental models demonstrate that Carvedilol blocks α1-, β1-, and β2-adrenergic receptors without exhibiting high levels of inverse agonist activity3. The lack of inverse agonist activity and intrinsic sympathomimetic activity (ISA) reduces the side-effects and makes the compound better tolerated than the older β-blockers. The pharmacologic effects of Carvedilol are related to the inhibition of multiple neurohormonal pathways. Additional studies indicate that some of the efficacy of Carvedilol may be associated with its effects on levels of inflammatory cytokines4. Carvedilol also blocks KV1.5 channels independently of its action on adrenoceptors5, as well as Kir2.3 and Kir3.2 channels6.
Target KV1.5, Kir2.3, Kir3.2 K+ channels, adrenoceptors
