产品描述

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]
