General description

Cyclopiazonic acid (CPA), a tetramic acid is synthesized by various Aspergillus and Penicillium species.

Application

Cyclopiazonic acid from Penicillium cyclopium has been used:
  • as a standard in aflatoxin detection and quantification by thin layer chromatography (TLC)
  • as a component in Ca2+-free DMEM/10% fetal bovine serum (FBS)
  • as a reversible inhibitor of the sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) to examine the role of luminal calcium in endoplasmic recticulum (ER)-to-Golgi trafficking
  • as an endoplasmic reticulum Ca2+-ATPase blocker, to treat neurons and also to study the role of the endoplasmic reticulum (ER) in releasing and sustaining Ca2+ during Ca2+-induced Ca2+ release (CICR) to inhibit SERCA

Biochem/physiol Actions

Inhibits the sarcoplasmic reticulum Ca2+-pump.
