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.

Spiramilactone B, a new diterpenoid from Speraea japonica var. stellaris[Reference: WebLink]


METHODS AND RESULTS:
A new atisine-type diterpenoid named Spiramilactone B(1) was isloated from the roots of Spiraea japonica var. stellaris. Its structure was established by a spectroscopic analysis. In addition, nine known compounds were also obtained, including a atisine-type diterpenoid, spiraminol (2) and eight diterpenoid alkaloids, spiramine A, B, C, D. F. H, P, Q.

A bio-inspired synthetic route to the core ring systems of Spiraea atisine-type diterpenoid alkaloids and related diterpenes.[Pubmed:26837236]

Org Biomol Chem. 2016 Mar 7;14(9):2716-22.

A bio-inspired synthetic strategy for the efficient construction of the structurally complex azapentacyclic ABEFG ring systems of Spiraea atisine-type diterpenoid alkaloids bearing a characteristic internal carbinolamine ether linkage between C(7) and C(20) has been successfully developed. The highly bridged azapentacyclic core structure was constructed rapidly from a readily prepared trans-6,6-bicyclic AB ring precursor through a 14-step sequence. Highlights of the synthesis include a straightforward formal lactone migration from the tricyclic gamma-lactone unit of naturally occurring spiramilactone E, and an efficient biomimetic synthesis of the azapentacyclic ABEFG ring systems of spiramines C and D from the corresponding tetracyclic subunits of spiraminol and Spiramilactone B.

Collective Total Syntheses of Atisane-Type Diterpenes and Atisine-Type Diterpenoid Alkaloids: (+/-)-Spiramilactone B, (+/-)-Spiraminol, (+/-)-Dihydroajaconine, and (+/-)-Spiramines C and D.[Pubmed:26545636]

Angew Chem Int Ed Engl. 2016 Jan 4;55(1):392-6.

The first total syntheses of the architecturally complex atisane-type diterpenes and biogenetically related atisine-type diterpenoid alkaloids (+/-)-Spiramilactone B, (+/-)-spiraminol, (+/-)-dihydroajaconine, and (+/-)-spiramines C and D are reported. Highlights of the synthesis include a late-stage biomimetic transformation of Spiramilactone B, a facile formal lactone migration from the pentacyclic skeleton of spiramilactone E, a highly efficient and diastereoselective 1,7-enyne cycloisomerization to construct the functionalized tetracyclic atisane skeleton, and a tandem retro-Diels-Alder/intramolecular Diels-Alder sequence to achieve the tricyclo[6.2.2.0] ring system.
