生化/生理作用

Kurarinone, a flavanone from Sophora flavescens roots, is a potent activator of the large-conductance calcium-activated potassium channel (BKCa channel). Kurarinone exhibits strong preference to potentiate the homomeric BKCa channel composed only of the α subunits. Kurarinone reduces acetylcholine induced contraction of rat urinary bladder strips and decreased the voiding frequency in a rat OAB model. Kurarinone exhibits cytotoxic and antiinflamatory activity. Kurarinone sensitizes TRAIL-induced tumor cell apoptosis via suppression of NF-KB-dependent cFLIP expression.

The large-conductance calcium-activated potassium channel (BKCa channel) plays critical roles in smooth muscle relaxation. In urinary bladder smooth muscle, BKCa channel activity underlies the maintenance of the resting membrane potential and repolarization of the spontaneous action potential triggering the phasic
