|Biological Activity or Inhibitors:||1. Senkyunolide O is a COX-2 selective inhibitor with the IC(50) value of 5 microM.
|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.|

|Discovery of cyclooxygenase inhibitors from medicinal plants used to treat inflammation.[Pubmed: 20188172 ]|
|Eleven authenticated botanicals used in the traditional Chinese medicine Huo-Luo-Xiao-Ling Dan were screened for ligands to cyclooxygenase (COX) using pulsed ultrafiltration liquid chromatography-mass spectrometry, and a mass spectrometry-based enzyme assay was used to determine the concentration of each of 17 ligands that inhibited COX-1 or COX-2 by 50% (IC(50)). Acetyl-11-keto-beta-boswellic acid, beta-boswellic acid, acetyl-alpha-boswellic acid, acetyl-beta-boswellic acid, and betulinic acid were COX-1 selective inhibitors with IC(50) values of approximately 10 microM. Senkyunolide O and cryptotanshinone were COX-2 selective inhibitors with IC(50) values of 5 microM and 22 microM, respectively. Roburic acid and phenethyl-trans-ferulate inhibited COX-1 and COX-2 equally. COX inhibition and the IC(50) values of most of these natural product ligands have not been reported previously.|

|Study on biligustilides from Angelica sinensis.[Pubmed: 19166005]|
|OBJECTIVE: To study the chemical constituents of Angelica sinensis. METHOD: The constituents were separated by chromatographic methods, and their structures were identified on the basis of spectroscopic analysis. RESULT: Eight compounds were isolated and identified as levistolide A (1), Senkyunolide O (2), (3Z, 3Z')-6.8', 7.3'-diligustilide (3), tokinolide B (4), isotokinolide B (5), (3'Z)-(3R, 8S, 3a'R, 6'S)-3, 3a': 8, 6'-biligustilide (6), E, E'-3. 3', 8. 8'-diligustilide (7) and E, E'-3. 3', 8. 8'-isodiligustilide (8), which are all diligustilides. CONCLUSION: Compound 7 was obtained from the plant for the first time; compounds 6 and 8 are new compounds.|
