[Study on biligustilides from Angelica sinensis].[Pubmed:19166005]
Zhongguo Zhong Yao Za Zhi. 2008 Oct;33(19):2196-201.
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.
Discovery of cyclooxygenase inhibitors from medicinal plants used to treat inflammation.[Pubmed:20188172]
Pharmacol Res. 2010 Jun;61(6):519-24.
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 Pharmacokinetics of Three Preparations from Levistolide A by LC-MS-MS.[Pubmed:25657289]
J Chromatogr Sci. 2015 Sep;53(8):1265-73.
A rapid sensitive analytical method was established and validated to investigate levistolide A in rat plasma by liquid chromatography-tandem mass spectrometry operated in the positive ion mode. Levistilide A (LA) and internal standard (IS) andrographolide (AD), mixed with the plasma sample, were separated on a reversed phase Spursil C18 5 microm column. The precursor/product transitions (m/z) were 398.5/381.3 for LA and (m/z) 368.0/351.1 for AD. The calibration curve was linear over the range from 5 to 1,250 ng/mL for oral administration and 10-4,000 for intravenous administration with a correlation coefficient (r) >/=0.9993. The lower limit of quantification was 5 ng/mL for LA in plasma. The inter- and intra-day accuracy and precision were less than +/-15% of the relative standard deviation. In this study, the developed method is successfully applied to the comparative pharmacokinetic study of LA in rats after oral administration of LA alone, Rhizoma Chuanxiong, and Danggui-Shaoyao-San along with the bioavailability study of LA in rats. Our study shows that low bioavailability (7.5%) is observed after oral administration of LA. Traditional formula compatibility of Danggui-Shaoyao-San could significantly enhance LA bioavailability compared with LA alone and Rhizoma Chuanxiong.
Description
Levistolide A (LA), a natural compound isolated from the traditional Chinese herb Ligusticum chuanxiong Hort, is used for treating cancer. Levistolide A can induce apoptosis via ROS-mediated ER stress pathway.
