CHM-1 is a potent, selective antitumor agent in human hepatocellular carcinoma in vitro. CHM-1 induces apoptosis, and it binds tubulin and inhibits tubulin polymerization in vitro. Noted to cause cell cycle arrest at G2/M phase by activation of Cdc kinase activity. Also, CHM-1 exhibits vascular targeting activity through upregulation of p53 and induction of death receptor (DR5)-mediated apoptosis in HUVEC cells. Furthermore reported to induce translocation of apoptosis inducing factor (AIF) from the mitochondria to nucleus.
