Cyclopiazonic acid-13C20 is intended for use as an internal standard for the quantification of cyclopiazonic acid by GC- or LC-MS. Cyclopiazonic acid is a mycotoxin that has been found in Penicillium and Aspergillus and an inhibitor of sarcoplasmic/endoplasmic reticulum Ca2+-ATPase (SERCA; IC50 = 0.6 µM).1,2 In vivo, cyclopiazonic acid (11-14 mg/kg) induces ptosis, hypothermia, tremor, and cachexia, as well as induces lethality (LD50 = 13 mg/kg), in rats.3 It induces tachycardia and sedation in rabbits when administered at a dose of 10 mg/kg.
