Honokiol is a natural product, which is extracted from the bark or seed cones of the Magnolia tree have been widely used in traditional medicine in China, Korea, and Japan. Houpu has traditionally been used in Eastern medicine as analgesic and to treat anxiety and mood disorders. In China, magnolia bark is called Houpu and is most commonly taken from the Magnolia obovata and the Magnolia officinalis species. In the late 1990s, honokiol saw a revival in interest as a potent and highly tolerable antitumorigenic and neurotrophic compound.

How to use

In Vitro:

Honokiol shows pro-apoptotic effects in melanoma, sarcoma, myeloma, leukemia, bladder, lung, prostate, oral squamous cell carcinoma and colon cancer cell lines. Honokiol is effective on inducing apoptosis in SVR angiosarcoma cells. Treatment of SVR cells with honokiol causes decreased phosphorylation of MAP kinase, akt, and c-src. In addition, honokiol potentiates TRAIL-mediated apoptosis, and honokiol cytotoxicity is partially abrogated by neutralizing antibodies to TRAIL. Honokiol also has direct antiangiogenic activity, in that honokiol blocks the phosphorylation and rac activation due to VEGF-VEGFR2 interactions. Honokiol causes apoptosis in CLL cells through activation of caspase 8, followed by caspase 9 and 3 activation. Honokiol prevents interleukin-4-mediated survival of CLL cells, and potentiats the cytotoxicity of chlorambucil, fludarabine, and cladribine. Honokiol kills myeloma cells from relapsed patients at doses that does not kill PBMCs. Caspase 3, 7, 8, and 9 are induced by honokiol treatment, as well as PARP cleavage. Honokiol is found to induce apoptosis in the colon cancer cell lines RKO. Honokiol potentiates apoptosis, suppresses osteoclastogenesis, and inhibits invasion through modulation of nuclear factor-kappaB activation pathway. Honokiol may act as a potent anti-inflammatory agent with multipotential activities due to an inhibitory effect on the PI3K/Akt pathway.

In Vivo:

Honokiol is highly effective against SVR angiosarcoma in nude mice. Honokiol inhibits the growth of RKO cells in murine xenografts. Honokiol prevents the growth of MDA-MD-231 breast cancer cells in murine xenografts.
