    Paxilline

    $82.29 - $288.02
    Paxilline is a tremorgenic mycotoxin isolated from species of Penicillium, Acremonium and Emericella.

    Paxilline is soluble in ethanol, methanol, DMF or DMSO. Poor water solubility.
    Mechanism of ActionPaxilline selectively blocks high-conductance Ca2+-activated potassium channels and inhibits binding to the cerebellar inositol 1,4,5-triphosphate (InsP(3)) receptor.
