Description: Paxilline is an indole alkaloid mycotoxin from Penicillium paxilli, acts as a potent BK channels inhibitor by an almost exclusively closed-channel block mechanism. Paxilline also inhibits the sarco/endoplasmic reticulum Ca2+ ATPase (SERCA) with IC50s between 5μM and 50μM for differing isoforms. Paxilline possesses significant anticonvulsant activity[1][2][3].
Target: IC50: 5-50 μM (SERCA)[2], BK channel[1]
