| | CYCLOPIAZONIC ACID Usage And Synthesis |
| Description | 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). 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. It induces tachycardia and sedation in rabbits when administered at a dose of 10 mg/kg. | | Chemical Properties | off-white powder or crystals | | Uses | 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
| | Uses | The use of Cyclopiazonic acid on Langendorff-perfused murine hearts displayed anti-arrhythmic effects. Also, administration of cyclopiazonic acid on rat soleus muscle showed a decrease in hormone sensitive lipase activity and triacylglycerol hydrolysis. It is also used as an inhibitor of endoplasmic reticulum Ca2+-ATPase. | | Uses | 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. | | General Description | Cyclopiazonic acid (CPA), a tetramic acid is synthesized by various Aspergillus and Penicillium species. | | Biological Activity | Cell-permeable, reversible inhibitor of sarcoplasmic reticulum Ca 2+ -ATPase. | | Biochem/physiol Actions | Inhibits the sarcoplasmic reticulum Ca2+-pump. | | storage | -20°C | | References | [1] N W SEIDLER.
