生物活性:
Verrucarin A (Muconomycin A), a Type D macrocyclic mycotoxin derived from the pathogen fungus Myrothecium verrucaria, is an inhibitor of protein synthesis. Verrucarin A inhibits growth of leukemia cell lines and activates caspases and apoptosis and inflammatory signaling in macrophages. Verrucarin A effectively increased the phosphorylation of p38 MAPK and diminished the phosphorylation of ERK/Akt. Verrucarin A caused cell cycle deregulation through the induction of p21 and p53.

体外研究:
Verrucarin A (0-0.6 μM/ml; 24-48 hours)-induces time- and dose-dependent growth inhibition in MCF-7 cells.Verrucarin A increases the levels of reactive oxygen species (ROS), and subsequently induces mitochondrial membrane potential (Δψm) loss, leading to the increase of Bax/Bcl-2 ratio, cytochrome c release, caspase activation, PARP degradation, and apoptosis.
