Biological Activity

Description Honokiol is the active principle of magnolia extract that inhibits Akt-phosphorylation and promotes ERK1/2 phosphorylation. Phase 3.
Akt-phosphorylation [1] MEK [1]
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. [1] 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. [3] 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. [2] Honokiol is found to induce apoptosis in the colon cancer cell lines RKO. [4] Honokiol potentiates apoptosis, suppresses osteoclastogenesis, and inhibits invasion through modulation of nuclear factor-kappaB activation pathway. [5] Honokiol may act as a potent anti-inflammatory agent with multipotential activities due to an inhibitory effect on the PI3K/Akt pathway. [6]

In vivo Honokiol is highly effective against SVR angiosarcoma in nude mice. [1] Honokiol inhibits the growth of RKO cells in murine xenografts. [4] Honokiol prevents the growth of MDA-MD-231 breast cancer cells in murine xenografts. [7]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
