Cat. No.: HY-13721 Purity: 99.76%
COA Handling Instructions

Phenoxodiol (Idronoxil), a synthetic analog of Genestein, activates the mitochondrial caspase system, inhibits XIAP (an apoptosis inhibitor), and sensitizes the cancer cells to Fas-mediated apoptosis. Phenoxodiol also inhibits DNA topoisomerase II by stabilizing the cleavable complex. Phenoxodiol induces cell cycle arrest in the G1/S phase of the cell cycle and upregulates p21WAF1 via a p53 independent manner.

Description

Phenoxodiol (Idronoxil), a synthetic analog of Genestein, activates the mitochondrial caspase system, inhibits XIAP (an apoptosis inhibitor), and sensitizes the cancer cells to Fas-mediated apoptosis. Phenoxodiol also inhibits DNA topoisomerase II by stabilizing the cleavable complex. Phenoxodiol induces cell cycle arrest in the G1/S phase of the cell cycle and upregulates p21WAF1 via a p53 independent manner[1][2].

IC50 & Target

Caspase, DNA topoisomerase II[1][2].

In Vitro

Phenoxodiol (Idronoxil) (0-10 μg/mL; 24 h) decreases cell viability of primary ovarian cancer cells[1].
Phenoxodiol (0-10 μg/mL; 24 h) induces apoptosis and restores sensitivity to Fas-mediated apoptosis in ovarian cancer cells[1].
Phenoxodiol (0-10 μg/mL; 24 h) induces caspase-8 activation and FLIP downregulation through the Akt-pathway. Phenoxodiol-induced apoptosis involves activation of the mitochondrial pathway and is caspase dependent. Phenoxodiol treatment results in downregulation and cleavage of XIAP[1].
Phenoxodiol (10 and 30 μM; 24 and 48 h) induces cell cycle arrest in the G1/S phase of the cell cycle in prostate cancer cells[2].

Result: A significant decrease in cell viabilityin all the ovarian cancer cell cultures was observed at a concentration of 10 μg/mL (41.6 μM) and did not affect ovarian surface epithelial (OSE) cells’ viability. In CP70 cells, the IC50 was 1.35 μM.

Apoptosis Analysis[1]

Cell Line: CP70 and OSE cells
Concentration: 10 μg/mL
Incubation Time: 24 h

Western Blot Analysis[1]

Cell Line: Ovarian cancer cells
Concentration: 10 μg/mL
Incubation Time: 24 h
Result: Induced caspase-8 activation, characterized bycleavage of procaspase-8 into its p43/41 and p28 forms and in downregulation of the p43 form of FLIPC in all the primarycultures as well as in the CP70 and Hey cell lines. Decreased the levels of Akt expression. Resulted in XIAP downregulation and cleavage to its 30 kDa inactive form.

Cell Cycle Analysis[2]

Cell Line: LNCaP, DU145 and PC3 cells
Concentration: 10 and 30 μM

Decreased the expression of Cyclin-D1 after 24 hours of treatment with 30 μM in DU145 and PC3 cells. Decreased the expression of Ki-67 after 24 hours of treatment with 10 and 30 μM in LNCaP and PC3 cells. Increased the expression of p21 in LNCaP and PC3 cells.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
