General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
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.

Enzyme-promoted regioselective coupling oligomerization of isorhapontigenin towards the first synthesis of (±)-gnetulin.[Pubmed: 24569530]


METHODS AND RESULTS:
We report the first synthesis of a natural (±)-Gnetulin and an unnatural analogue of (±)-gnemonol M by using the regioselective oxidative coupling reactions of 5-tert-butyl-isorhapontigenin as the key step. Both the effects of different enzyme-catalyzed systems on the structures of coupling products and structural transformations of coupling products in the presence of several Lewis acids were systematically investigated.

Bioactive stilbene dimers from Gnetum cleistostachyum.[Pubmed: 15938189]


METHODS AND RESULTS:
Two new stilbene dimers, named bisisorhapontigenin A (1) and cis shegansu B (2), together with gnetuhainin P (3) and Gnetulin (4), were isolated from the lianas of Gnetum cleistostachyum C. Y. Cheng. Their structures were elucidated by means of spectroscopic evidences, including UV, IR, MS, 1H NMR, 13C NMR, NOE and 2D NMR, respectively. The pharmacological activities of compounds 1, 2 and 3 also have been tested.
