|Biological Activity or Inhibitors:||1. Alloisoimperatorin is a candidate of AChE inhibitors.
2. Alloisoimperatorin has estrogenic activity on the Ishikawa cell line, it shows strong ability to induce alkaline phosphatase (AP) with the EC50 values of 0.8 microg/mL.
3. Alloisoimperatorin displays potent antioxidant effects against the DPPH radical and against renal epithelial cell injury by using AAPH to generate peroxyl radicals in vitro.
|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.

|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.|

|Acetylshikonin, a Novel AChE Inhibitor, Inhibits Apoptosis via Upregulation of Heme Oxygenase-1 Expression in SH-SY5Y Cells.[Pubmed: 24302971]|
|Acetylcholinesterase inhibitors are prominent alternative in current clinical treatment for AD patients. Therefore, there is a continued need to search for novel AChEIs with good clinical efficacy and less side effects. By using our in-house natural product database and AutoDock Vina as a tool in docking study, we have identified twelve phytochemicals (emodin, aloe-emodin, chrysophanol, and rhein in Rhei Radix Et Rhizoma; xanthotoxin, phellopterin, Alloisoimperatorin, and imperatorin in Angelicae dahuricae Radix; shikonin, acetylshikonin, isovalerylshikonin, and β,β-dimethylacrylshikonin in Arnebiae Radix) as candidates of AChEIs that were not previously reported in the literature. In addition to AChEI activity, a series of cell-based experiments were conducted for the investigation of their neuroprotective activities.|

|Estrogenic activity of furanocoumarins isolated from Angelica dahurica.[Pubmed: 17024846]|
|In our efforts to discover novel phytoestrogens to treat menopausal symptoms, eleven furanocoumarins were isolated from Angelica dahurica and tested for their estrogenic activity on the Ishikawa cell line. Among the compounds tested, 9-hydroxy-4-methoxypsoralen and Alloisoimperatorin showed strong abilities to induce alkaline phosphatase (AP) with EC50 values of 1.1 and 0.8 microg/mL, respectively, whereas the other nine furanocoumarins were weakly or only slightly active.|

|Antioxidative activity of furanocoumarins isolated from Angelicae dahuricae.[Pubmed: 15234759 ]|
|The methylene chloride extract of the root of Angelicae dahuricae showed high protective activity against 2,2'-azobis (2-aminodinopropane) dihydrochloride (AAPH)-induced cellular damage. From this extract, 11 furanocoumarins were isolated, namely oxypeucedanin hydrate, 9-hydroxy-4-methoxypsoralen, byakangelicin, pabulenol, Alloisoimperatorin, neobyakangelicol, byakangelicol, oxypeucedanin, imperatorin, phellotorin and isoimperatorin, respectively. Among these 11 furanocoumarins, 9-hydroxy-4-methoxypsoralen and Alloisoimperatorin displayed potent antioxidant effects against the DPPH radical and against renal epithelial cell injury by using AAPH to generate peroxyl radicals in vitro|
