Phenoxodiol (Haginin E)

Synonyms: Idronoxil, Dehydroequol, NV 06, PXD

Phenoxodiol (Haginin E, Idronoxil, Dehydroequol, NV 06, PXD) is an isoflavone analog with antineoplastic activity that activates the caspase system, inhibits XIAP (X-linked inhibitor of apoptosis), and disrupts FLICE inhibitory protein (FLIP) expression, resulting in tumor cell apoptosis. Phenoxodiol also inhibits DNA topoisomerase II.

Biological Activity

Description Phenoxodiol (Haginin E, Idronoxil, Dehydroequol, NV 06, PXD) is an isoflavone analog with antineoplastic activity that activates the caspase system, inhibits XIAP (X-linked inhibitor of apoptosis), and disrupts FLICE inhibitory protein (FLIP) expression, resulting in tumor cell apoptosis. Phenoxodiol also inhibits DNA topoisomerase II.

In vitro
In vitro

Primary ovarian cancer cells, isolated from ascitic fluids of ovarian cancer patients, resistant to conventional chemotherapy, undergo apoptosis following phenoxodiol treatment. This effect is dependent upon the activation of the caspase system, inhibiting XIAP, an inhibitor of apoptosis, and disrupting FLICE inhibitory protein (FLIP) expression through the Akt signal transduction pathway. Phenoxodiol is an efficient inducer of cell death in ovarian cancer cells and sensitizes the cancer cells to Fas-mediated apoptosis.[1]
Cell Research Cell lines primary ovarian cancer cells
Concentrations 0.1 μg/ml, 1 μg/ml, 10 μg/ml
Incubation Time 24 h
Method

Cells are treated in the presence or absence of 500 ng/ml Fas-antibody in Optimem for 24 h or with 0.1, 1 or 10 μg/ml phenoxodiol, NV03, NV05 or NV07 in Optimem for 24 h. For treatment with phenoxodiol and caspase inhibitors, 10 μg/ml phenoxodiol is used alone, or in combination with 20 μM general caspase-inhibitor Z-VADFMK and incubated for 24 h.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
