一般描述

色原烷醇293B对映体是钾通道蛋白(KvLQT1)的一种有效抑制剂。在人心房肌细胞中,色原烷醇293B可抑制复极钾电流。色原烷醇293B可通过调节钾电压门控通道(KCNQ1)而改善胰腺中葡萄糖刺激的胰岛素分泌(GSIS)。

应用

色原烷醇293B已用于抑制人上皮细胞系中钙和环腺苷一磷酸(cAMP)激活的钾通道。色原烷醇293B已用于心肌细胞的膜片钳电生理学研究。

生化/生理作用

通过KCNQ1通道阻断慢延迟整流器K+

Colonic crypts are the site of Cl- secretion. Basolateral K+ channels provide the driving force for luminal cystic fibrosis transmembrane regulator-mediated Cl- exit. Relevant colonic epithelial K+ channels are the intermediate conductance Ca2+-activated K(Ca)3.1 (SK4) channel and the cAMP-activated K(V)7.1
