Cyclopiazonic acid is an endoplasmic reticulum calcium ATPase (ECAs) inhibitor and human respiratory syncytial virus (RSV) inhibitor (EC50 value of 4.13 μ M), which can reduce the antagonistic effect of 5-HT receptors in rat thoracic aorta, induce p53 dependent cell apoptosis and reproductive toxicity in mouse testes, and inhibit the biological activation of aflatoxin B[1][4][5].
