Astin B
Astin B is a orally active and potent cyclic pentapeptide, that can be isolated from Aster tataricus. Astin B has hepatotoxic effects in vitro and in vivo and that hepatic injury was primarily mediated by apoptosis in a mitochondria/caspase-dependent manner. Astin B induces autophagy in L-02 cells, increases LC3-II and decreases p62 expression.

Astin B (0-60 μM, 12-48 h) inhabits proliferation of L-02 cells[1].
Astin B (0-60 μM, 24 h) induces oxidative stress and mitochondrial dysfunction, regulates Bcl-2/Bax expression and increases caspase-3 and -9 activity[1].
Astin B (0-60 μM, 24 h) induces autophagy in L-02 cells to protect from apoptosis[1].
Astin B provokes oxidative stress-associated inflammation in hepatocytes as evidenced by increased levels of reactive oxygen species (ROS), reduced contents of intracellular glutathione (GSH), and enhanced phosphorylation of c-Jun N-terminal kinase (JNK)[1].
