    Paxilline
    5+ Cited Publications

    		 Potassium Channel Calcium Channel Reactive Oxygen Species (ROS) Neurological Disease
    Paxilline is an indole alkaloid mycotoxin derived from Penicillium paxilli, which effectively inhibits the BK channel through a channel-blocking mechanism. Paxilline also inhibits sarco/endoplasmic reticulum Ca 2+-stimulated ATPase (SERCA), with IC50 values ranging from 5 μM to 50 μM for different SERCA isoforms. Paxilline exhibits significant anticonvulsant and neuroprotective effects, as well as certain antioxidant activity .

    (17R,18S)-Epoxyeicosatetraenoic acid

    17(R),18(S)-EETeTr

    		 Calcium Channel Cardiovascular Disease
    (17R,18S)-Epoxyeicosatetraenoic acid (17 (R),18 (S)-EETeTr) is a physiologically active fatty acid metabolite and also a vasodilator targeting BKα. (17R,18S)-Epoxyeicosatetraenoic acid activates the outward potassium current mediated by BK channels, and this effect is independent of the BKβ1 subunit, intracellular/extracellular calcium levels, and sarcoplasmic reticulum calcium release regulated by RyR3. (17R,18S)-Epoxyeicosatetraenoic acid is produced by the epoxidation of eicosapentaenoic acid mediated by CYP1A1 variants. (17R,18S)-Epoxyeicosatetraenoic acid is applicable to research related to arrhythmia .
