We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Biological Activity of Calyxin B

Description1. Calyxin B exhibits potent activity against human HT-1080 fibrosarcoma cells with an ED50 value of 0.69 microM. 2. A methylated product of calyxin A and an epimeric mixture of Calyxin B, showed greatly reduced activity suggesting that phenolic hydroxyl groups are involved in the inhibitory activity.

Antiproliferative activity of diarylheptanoids from the seeds of Alpinia blepharocalyx.[Pubmed:11379774]

Biol Pharm Bull. 2001 May;24(5):525-8.

The 95% EtOH extract of the seeds of Alpinia blepharocalyx (Zingiberaceae) showed significant antiproliferative activity towards human HT-1080 fibrosarcoma and murine colon 26-L5 carcinoma cells. Chemical investigation of the extract led to the isolation of forty-four new (1-44) and one known (45) diarylheptanoids, eleven phenolic compounds (46-56) together with beta-sitosterol glucoside (57). Almost all the isolated compounds showed significant antiproliferative activity in a concentration-dependent manner. Among the compounds, epicalyxin F (17) exhibited the most potent activity against the proliferation of colon 26-L5 carcinoma cells with an ED50 value of 0.89 microM, while Calyxin B (2) exhibited the most potent activity against human HT-1080 fibrosarcoma cells with an ED50 value of 0.69 microM. Moreover, calyxins B (2) and K (11), epicalyxins F (17), I (20) and K (22), 6-hydroxycalyxin F (25), blepharoCalyxin B (27) and mixtures of 7 and epicalyxin G (18) and of calyxin J (10) and epicalyxin J (21) possessed more potent activity than a clinically used anticancer drug, 5-fluorouracil, towards HT-1080 fibrosarcoma cells. Analysis of the structure activity relationship suggested that the position of the attachment of a chalcone or a flavanone moiety does not affect the activity, although their presence in association causes a substantial enhancement of the antiproliferative activity. Moreover, the conjugated double bond of the chalcone moiety and the phenolic hydroxyl group potentiate the antiproliferative activity of the compounds.

Inhibitory effect of diarylheptanoids on nitric oxide production in activated murine macrophages.[Pubmed:9586575]

Biol Pharm Bull. 1998 Apr;21(4):371-4.

Thirteen novel diarylheptanoids bearing a chalcone or a flavanone moiety (1-13), a new curcumin derivative, 1,2-dihydrobis(de-O-methyl)curcumin (14), and two known flavonoids (15 and 16) isolated from the seeds of Alpinia blepharocalyx K. Schum. were tested for their inhibitory effects on nitric oxide (NO) production in lipopolysaccaride (LPS)-activated murine macrophages J774.1 in vitro. All the tested compounds inhibited NO production in a concentration-dependent manner (IC50=36-568 microM). Among the compounds examined, blepharoCalyxin B (13) was the most potent inhibitor of NO production (IC50=36 microM). Analysis of the structure activity relationship among these novel diarylheptanoids led to the conclusion that the position of attachment of a chalcone or a flavanone to a diarylheptanoid does not affect their inhibitory potency although their presence in association causes a substantial enhancement of the inhibitory activity. Moreover, a conjugated double bond in a chalcone moiety potentiated the inhibitory activity. On the other hand, hexamethoxydeoxycalyxin A (17) and pentamethoxyCalyxin B (18), a methylated product of calyxin A (1) and an epimeric mixture of Calyxin B, showed greatly reduced activity suggesting that phenolic hydroxyl groups are involved in the inhibitory activity.
