Myrothecine A is a trichothecene mycotoxin found in M. roridum. Myrothecine A induces apoptosis , promotes the cytochrome c release, PARP-cleavage and phosphorylation of JNK , increases Bax and cleaved caspase-3 , -5, and -8 levels. Myrothecine A has anticancer activities and promotes the maturation of DC cells in the microenvironment. Myrothecine A inhibits proliferation of A549, MCF-7, HepG2, and SMMC-7721 cancer cells with IC 50 s of 95, 70, 60, and 25 µM, respectively.
