    Cyclopiazonic acid

    $79.00 - $274.00
    Cyclopiazonic acid is a tremorigenic indole produced by several species of Aspergillus and Penicillium. Cyclopiazonic acid is a highly specific inhibitor of calcium ATPase of sarcoplasmic reticulum, altering calcium homeostasis and ATP-dependent calcium transport and resulting in the release of intracellular stored Ca2+ without increasing IP3.

    Cyclopiazonic acid is soluble in ethanol, methanol, DMF and DMSO.   
    Mechanism of ActionCyclopiazonic acid is a highly specific inhibitor of calcium ATPase of sarcoplasmic reticulum, altering calcium homeostasis and ATP-dependent calcium transport and resulting in the release of intracellular stored Ca2+ without increasing IP3.
