| Description: |
5,7,3′,4′-Tetrahydroxy-3-methoxy-8,5′-diprenylflavone has anti-cancer activity, it shows potent anti-proliferation effects on ER-positive breast cancer MCF-7 cells in vitro, with the IC50 value of 4.41 uM. 5,7,3′,4′-Tetrahydroxy-3-methoxy-8,5′-diprenylflavone can strongly down-regulate expression concentrations of estrogen receptor-α (ER-α) and is able to inhibit tumor growth in a xenograft model of the human breast cancer line BCAP-37 in vivo. |
| Targets: |
Estrogen receptor | Progestogen receptor |
| In vitro: |
| Phytochemistry Letters, 2013, 6(3):331-336. | | Prenylflavone derivatives from Broussonetia papyrifera, inhibit the growth of breast cancer cells in vitro and in vivo.[Reference: WebLink] |
METHODS AND RESULTS:
Two new prenylflavones 5,7,3′,4′-tetrahydroxy-3-methoxy-8-geranylflavone (1) and 5,7,3',4'-Tetrahydroxy-3-methoxy-8,5'-diprenylflavone (2), as well as four known ones, uralenol (3), papyriflavonol A (4), broussoflavonol B (5) and broussochalcone A (6) were isolated and purified from an ethyl acetate-soluble extract of the barks of Broussonetia papyrifera. Their structures were determined with the spectroscopic methods including HR-EI-MS, 1D and 2D NMR. We found that compounds 2–6 showed potent anti-proliferation effects on ER-positive breast cancer MCF-7 cells in vitro. The IC50 values of compounds 2 and 5 were 4.41 and 4.19 μM respectively after the treatment of 72 h. We also found that compounds 2 and 5 strongly down-regulated expression concentrations of estrogen receptor-α (ER-α) and were able to inhibit tumor growth in a xenograft model of the human breast cancer line BCAP-37 in vivo.
CONCLUSIONS:
Our results demonstrated that prenylflavones from B. Papyrifera exhibit potent anti-tumor activity. |

5,7,3',4'-Tetrahydroxy-3-methoxy-8,5'-diprenylflavone Description
| Source: |
The barks of Broussonetia papyrifera. |
| Solvent: |
Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc. |
| Storage: |
Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

| After receiving: |
The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling. |
