Cyclopiazonic acid is a mycotoxin produced by molds including certain species of Penicillium and Aspergillus. Its toxicity is linked to its ability to specifically and reversibly inhibit sarco-endoplasmic reticulum Ca2+-ATPases (SERCA; IC50 = 0.6 μM).1,2 Cyclopiazonic acid does not inhibit a wide variety of other types of membrane-bound ATPases. It effectively inhibits SERCA in intact tissue, in smooth muscle and endothelium, as well as in isolated cells.3,4

Cayman Chemical Company regularly evaluates our shipping methods to ensure product stability is maintained and our corporate environmental impact is minimized. Products selected for review are evaluated and shipping methods are certified by our Scientists. While occasionally our method of shipping a product may change, rest assured the shipping conditions on all Cayman Chemical products have been reviewed and validated.
Upon receipt, it is important to check the storage requirements of your products and place them at the appropriate temperature. Products shipped without ice may require frozen storage for long term stability.
Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
