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.

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.

Generating skeletal diversity from the c19 -diterpenoid alkaloid deltaline: a ring-distortion approach.[Pubmed:
25950550]
The development of new drugs calls for large collections of diverse molecules with considerable complexity. Ring distortion of natural products provides an efficient and facile approach to access new architectures with intriguing biological activities, by harnessing their inherent complexity.
METHODS AND RESULTS:
In this study, such a strategy has been explored on an abundant C19 -diterpenoid alkaloid, Deltaline, enabling the synthesis of 32 new derivatives bearing a broad spectrum of unique scaffolds. Extensive spectroscopic studies including X-ray crystallographic analyses strongly supported the structures of the obtained novel skeletons, which present comparable opportunities with the great contributions made by nature for discovery of new lead compounds.

Unusual reactions of a 7,17-seco-type C19-diterpenoid alkaloid derived from deltaline.[Pubmed:
22816291]
Treatment of a 7,17-seco-type C19-diterpenoid alkaloid (3), prepared from Deltaline (8), with triethylamine in either DMF or TEG (triethylene glycol) at 120 degrees C provided two interesting compounds 6 and 7. The structures of compounds 3, 6, and 7 were established based on extensive interpretations of their 1D and 2D NMR data. Compound 6, a lycoctonine-type C19-diterpenoid alkaloid, can be transformed from alkaloid 3 via Grob fragmentation, Prins reaction, and intramolecular disproportionation. The mechanism of the formation of compound 6 was confirmed by deuteration experiments. Product 7 was formed through a pinacol-like rearrangement of alkaloid 3.
