Bioassay- and liquid chromatography/mass spectrometry-guided acetylcholinesterase inhibitors from Picriafel-terrae.[Pubmed:24143041]
Pharmacogn Mag. 2013 Oct;9(Suppl 1):S25-31.
BACKGROUND: Picria fel-terrae is a traditional Chinese medicine. MATERIALS AND METHODS: A new approach to the search for acetylcholinesterase (AChE) inhibitors from Picria fel-terrae is presented. RESULTS: Bioassay- and LC-MS-guided fractionation of the ethyl acetate extract was from traditional Chinese medicine P.fel-terrae. Following primary extraction, the ethyl acetate extracts fraction of P.fel-terrae showed strong AChE inhibitory activities. So the sample was separated using highperformance liquid chromatography (HPLC). The effluent was split towards two identical 96-well fraction collectors, and the presence of the biologically interesting portion and chromatographic fractions could be readily detected by analyzing selected ion chromatograms through an electrophoresis-electrospray ionization mass spectrometry (ESIMS) system for accurate mass measurement. One 96-well plate was used for a bioassay (AChE-inhibitory assay) and detected the bioactivity and position of the relevant peak in the chromatogram. The positive well in the second 96-well plate was used for identification by LC-(+) ESIMS. CONCLUSION: As abovementioned, the AChE inhibitory constituents from P.fel-terrae by LC-bioassay-ESIMS were rapid identified. Liquid chromatography/ mass spectrometry (LC-MS) screening detected the presence of six active compounds, identified as picfeltarraenin IA (1), picfeltarraenin IB (2), Picfeltarraenin IV (3), picfeltarraenin X (4), picfeltarraenin XI (5), and one unknown compound. The structures were further determined by 13C NMR. The six compounds expressed stronger AChE inhibition than the known AChE inhibitorTacrine. Above all, the value of this LC-bioassay-ESIMS methodology is highlighted by the finding and structure elucidation of the active constituents from many other structural families of natural products.
A new cucurbitacin from Picria fel-terrae.[Pubmed:16864449]
J Asian Nat Prod Res. 2006 Jun;8(4):367-71.
A new cucurbitacin, picfeltarraenone II (1) as well as four known cucurbitacins, picfeltarraegenin I (2), picfeltarraenin IA (3), picfeltarraenin IB (4), and Picfeltarraenin IV (5), have been isolated and characterized from the whole plant of Picria fel-terrae. The purity of picfeltarraenin IA has been determined by TLC and HPLC.
Complement-inhibiting cucurbitacin glycosides from Picria fel-terrae.[Pubmed:9644059]
J Nat Prod. 1998 Jun 26;61(6):757-61.
Four cucurbitacin glycosides were isolated from Picriafel-terrae and identified by MS and NMR spectroscopy as picfeltarraenin IA (1), picfeltarraenin IB (2), Picfeltarraenin IV (4), and a new compound picfeltarraenin VI (3) (picfeltarraegenin I 3-O-beta-D-xylopyranoside). All four compounds acted as inhibitors on both the classical and alternative pathways of the complement system, with compound 3 exhibiting the highest inhibitory activity (IC50 29 +/- 2 microM and 21 +/- 1 microM, respectively). Compounds 1-4 showed no antiviral, antibacterial, or antifungal activities. Picfeltarraenin IA and IB were tested in an in vitro human tumor cell line panel, but displayed no cytotoxic activity.
