Biological Activity
Description: Alexine is a weak inhibitor of glucosidase.
Alexine Description
Source: The herbs of Alexa leiopetala
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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

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.

Asymmetric total synthesis of natural pyrrolizidine alkaloid, (+)-alexine[Reference: WebLink]

METHODS AND RESULTS:
The total synthesis of the potent glycosidase inhibitor (+)-Alexine with five contiguous stereogenic centres [(1R,2R,3R,7S,7aS)-3-hydroxymethyl-1,2,7-trihydroxypyrrolizidine alkaloid] is described featuring the efficient and stereodefined novel elaboration of the functionalized homochiral lactam derived from 2,3,5-tri-O-benzyl-β-d-arabinofuranose.

New asymmetric strategy for the total synthesis of naturally occurring (+)-alexine and (−)-7-epi-alexine[Reference: WebLink]

METHODS AND RESULTS:
(+)-Alexine [(1R,2R,3R,7S,7aS)-3-hydroxymethyl-1,2,7-trihydroxypyrrolizidine] and (−)-7-epi-Alexine [(1R,2R,3R,7R,7aS)-3-hydroxymethyl-1,2,7-trihydroxypyrrolizidine], as the potent glycosidase inhibitors by featuring the efficient and stereodefined elaboration of the functionalized pyrrolidine derivatives, which were, in turn, prepared via stereoselective manipulation of the homochiral allyl alcohol precursors derived from l-xylose.
