Biological Activity
Description: Pinostrobin chalcone is a potent inhibitor of triglyceride accumulation, it can inhibit adipogenesis in 3T3-L1 cells, it may have anti-obesity effects through the inhibition of adipogenesis. Pinostrobin chalcone displays very remarkable cytotoxic activity against the human cancer cells, such as KB, MCF7 and Caski cells (IC50 values of 6.2, 7.3 and 7.7 ug/mL, respectively).
Targets: Fatty Acid Synthase
In vitro:

Inhibitory effects of compounds isolated from the dried branches and leaves of murta (Myrceugenia euosma) on lipid accumulation in 3T3-L1 cells.[Pubmed: 26880616 ]
As obesity is a global health concern the demand for anti-obesity drugs is high. In this study, we investigated the anti-obesity effect of the dried branches and leaves of murta (Myrceugenia euosma Legrand, Myrtaceae).
METHODS AND RESULTS:
A methanol extract of the dried branches and leaves of murta inhibited adipogenesis in 3T3-L1 cells. Three known flavanones-cryptostrobin (1), pinocembrin (4), and 5,7-dihydroxy-6,8-dimethylflavanone (6), and three chalcones-2',6'-dihydroxy-3'-methyl-4'-methoxychalcone (2), Pinostrobin chalcone (3), and 2',6'-dihydroxy-4'-methoxy-3',5'-dimethylchalcone (5) were isolated from the active fraction. Structures of these compounds were identified using various spectral data. Each of these compounds also inhibited adipogenesis in 3T3-L1 cells. In particular, compound 3 was a more potent inhibitor of triglyceride accumulation than the positive control berberine. Gene expression studies revealed that treatment of 3T3-L1 cells with 3 lowers the expression levels of CCAAT/enhancer-binding protein α and peroxisome proliferator activator γ2 during adipogenesis without affecting cell viability. Treatment of 3T3-L1 cells with 3 reduced the expression levels of mRNAs encoding sterol regulatory element-binding protein 1c and several lipogenic enzymes, including fatty acid synthase and stearoyl CoA desaturase-1.
CONCLUSIONS:
These results indicate that the methanol extract and compounds isolated from the dried branches and leaves of murta exert their anti-obesity effects through the inhibition of adipogenesis.

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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

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.

Phytochemical and cytotoxic investigations of Alpinia mutica rhizomes.[Pubmed: 21240148]
The methanol and fractionated extracts (hexane, ethyl acetate and water) of Alpinia mutica (Zingiberaceae) rhizomes were investigated for their cytotoxic effect against six human carcinoma cell lines, namely KB, MCF7, A549, Caski, HCT116, HT29 and non-human fibroblast cell line (MRC 5) using an in vitro cytotoxicity assay.
METHODS AND RESULTS:
The ethyl acetate extract possessed high inhibitory effect against KB, MCF7 and Caski cells (IC₅₀ values of 9.4, 19.7 and 19.8 µg/mL, respectively). Flavokawin B (1), 5,6-dehydrokawain (2), Pinostrobin chalcone (3) and alpinetin (4), isolated from the active ethyl acetate extract were also evaluated for their cytotoxic activity. Of these, Pinostrobin chalcone (3) and alpinetin (4) were isolated from this plant for the first time.
CONCLUSIONS:
Pinostrobin chalcone (3) displayed very remarkable cytotoxic activity against the tested human cancer cells, such as KB, MCF7 and Caski cells (IC₅₀ values of 6.2, 7.3 and 7.7 µg/mL, respectively). This is the first report of the cytotoxic activity of Alpinia mutica.
