|Description:||1. (+)-Goniopypyrone suppresses the growth of cultured Ehrlich ascites tumor cells as well as PU5-1.8 cells. |
|Source:||The herbs of Goniothalamus yunnanensis|
|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.|

|Antitumor effect of chemically synthesized (+)-goniopypyrone.[Pubmed: 8458246]|
|Chemically synthesized (+)-Goniopypyrone was found to suppress the growth of cultured Ehrlich ascites tumor cells as well as PU5-1.8 cells. The ED50 values were found to be 35 and 30 micrograms/ml for the two cell lines used. An LD50 of 193 micrograms/ml was observed in the brine shrimp bioassay.|

|Cytotoxic styryl-lactones from the leaves and twigs of Polyalthia crassa.[Pubmed: 17190450 ]|
|Four new styryl-lactones, crassalactones A-D (1-4), were isolated from a cytotoxic ethyl acetate-soluble extract of the leaves and twigs of Polyalthia crassa, together with seven known compounds, (+)-3-acetylaltholactone, (+)-altholactone, aristolactam AII, cinnamic acid, (+)-goniofufurone, (+)-Goniopypyrone, and (+)-howiinol A. Their structures were determined on the basis of spectroscopic methods. The absolute configuration of 1-3 was established by chemical conversions. Single-crystal X-ray analysis and the Mosher ester method were used to confirm the absolute stereochemistry of 4. Cytotoxic evaluation against several mammalian cancer cell lines was performed on all new isolates, aristolactam AII, and the modified (+)-tricinnamate derivative 11 obtained from 1.|
