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.

Biological Activity of Strychnistenolide

In vitro

Sesquiterpene lactones from the root tubers of Lindera aggregata.[Pubmed: 19639966 ]

J Nat Prod. 2009 Aug;72(8):1497-501.


METHODS AND RESULTS:
Phytochemical investigation of the root tubers of Lindera aggregata resulted in the isolation of five new sesquiterpene lactones, linderagalactones A-E (1-5), along with eight known sesquiterpenoids, 3-eudesmene-1beta,11-diol, hydroxylindestenolide, Strychnistenolide, hydroxyisogermafurenolide, atractylenolide III, linderane, neolinderalactone, and linderalactone. The structures and relative configurations of 1-5 were determined by spectroscopic methods, especially HRESIMS and 2D NMR techniques. The absolute configurations of 1-4 were defined by comparison of quantum chemical TDDFT calculated and experimental ECD spectra.
CONCLUSIONS:
Linderagalactone A (1) is a halogenated sesquiterpene lactone possessing a unique rearranged carbon skeleton. Linderagalactone E (5), linderane, hydroxylindestenolide, and linderalactone showed hepatoprotective activity against H2O2-induced oxidative damages on HepG2 cells with EC(50) values of 67.5, 167.0, 42.4, and 98.0 microM, respectively.

New eudesmane sesquiterpenes from the root of Lindera strychnifolia.[Pubmed: 11277740]


METHODS AND RESULTS:
Strychnistenolide (1) and its acetate 2 were isolated from the root of Lindera strychnifolia, along with a novel rearranged type of secoeudesmane, strychnilactone (3). Their structures were elucidated by extensive analysis of their NMR spectra, including 2D NMR techniques, together with an X-ray analysis for 3.
CONCLUSIONS:
Strychnistenolide exists as a single stereoisomer in CHCl(3), but in pyridine is epimerized.
