Paxilline
Paxilline is an indole diterpene from fungi which potently and reversibly inhibits large conductance Ca2+-activated K+ (BKCa, KCa1.1) channels[1,2]. It also enhances the binding of charybdotoxin, a peptidyl neurotoxin, to BKCa channels. Paxilline also inhibits the sarco/endoplasmic reticulum Ca2+ ATPase (IC50 = 5 - 50 μM)[3].
