Peroxisome proliferator-activated receptor gamma (PPARγ) is a key regulator of glucose and lipid metabolism and therefore an important pharmacological target to combat metabolic diseases. Since the currently used full PPARγ agonists display serious side effects, identification of novel ligands,
The roots of Bupleurum chinense have a long history in traditional medicine to treat infectious diseases and inflammatory disorders. Two major compounds, saikosaponins A and D, were reported to exert potent anti-inflammatory activity by inhibiting NF-κB. In the present study, we isolated new
Linoleic acid, osthol, osthenol and two polyacetylenes, falcarindiol and 11(S),16(R)-dihydroxyoctadeca-9Z,17-diene-12,14-diyn-1 -yl acetate were found to be the most active compounds responsible for the inhibitory activity of the dichloromethane extract of the roots of Angelica pubescens f.
No conflicts of interest concerning financial matters or personal relationships exist between the authors and those who might bias this work. The present work is in part included the PhD thesis of A. Schinkovitz (University of Graz) but has not been published elsewhere previously. The
Conium maculatum is known as highly toxic plant, due to piperidine alkaloids present in the aerial parts. In a first attempt, in various tap root samples, however, alkaloids could not be detected. The present study describes active compounds in the tap roots from 16 populations harvested at
Sub-aerial parts of Chaerophyllum aureum L. yielded two polyacetylenes, falcarinol (1), falcarindiol (2), three lignans, namely nemerosin (3), deoxypodorhizone (4), deoxypodo-phyllotoxin (5), two phenylpropanoids, 1'-hydroxymyristicin (6) and its angeloyl ester (7). Compounds 6 and 7 were isolated
A dichloromethane extract of root celery yielded falcarinol, falcarindiol, panaxydiol, and the new polyacetylene 8-O-methylfalcarindiol. The structure of the new compound was established by one- and two-dimensional (1D and 2D) NMR, mass spectrometry, and optical rotation data. Nonpolar extracts of
A dichloromethane (DCM) extract of carrot roots was found to stimulate insulin-dependent glucose uptake (GU) in adipocytes in a dose dependent manner. Bioassay-guided fractionation of the DCM extract resulted in the isolation of the polyacetylenes falcarinol and falcarindiol. Both polyacetylenes
