一般描述
Paxilline is an indole diterpene metabolite produced by fungi. It has a functionalized pentacyclic core and is a template for the synthesis of a wide variety of derivatives.
应用
Paxilline has been used to block large conductance calcium activated potassium channels (BKCa) in murine smooth muscle cells and in myometrial cells of uterine samples. Paxilline acts as an agonist and activates liver X receptor in atlantic salmon.
生化/生理作用
Paxilline is a selective blocker of high-conductance Ca2+-activated (Maxi-K) potassium channels. It also blocks big potassium (BK) channels.
