Lignans from Kadsura angustifolia.
A new dibenzocyclooctadiene lignan named angustifolin D (1) together with four known lignans: kadsulignan L (2), kadsulignan N (3), schisantherin P (4) and meso-dihydroguaiaretic acid (5) were isolated from the stems of Kadsura angustifolia. Their structures and stereochemistries were elucidated by spectral studies. Compounds 2 and 5 showed moderate platelet-activating factor (PAF) antagonistic...
متن کاملNew Lignans from the Leaves and Stems of Kadsura philippinensis.
Three novel C19 homolignans, taiwankadsurins D (1), E (2) and F (4), and two new C18 lignans kadsuphilins N (3) and O (5) were isolated from the aerial parts of Taiwanese medicinal plant Kadsura philippinensis. The structures of compounds 1-5 were determined by spectroscopic analyses, especially 2D NMR techniques. The structure of compound 5 was further confirmed by X-ray crystallographic analy...
متن کاملNew Dibenzocyclooctadiene Lignans from Schisandra sphenanthera and Their Pro-inflammatory Cytokine Inhibitory Activities
Investigation of the fruits of Schisandra sphenanthera led to the isolation of two new dibenzocyclooctadiene lignans, methylgomisin O (1) and chloromethyl schisantherin B (2), together with twelve known lignans (3 – 14). Their structures were elucidated by using extensive spectroscopic techniques including 1D and 2D NMR spectra. Compound 2 was identified as a cyclooctadiene moiety substituted w...
متن کاملDibenzocyclooctadiene lignans and lanostane derivatives from the roots of Kadsura coccinea and their protective effects on primary rat hepatocyte injury induced by t-butyl hydroperoxide.
A new dibenzocyclooctadiene lignan, acetylepigomisin R ( 1), and a new 3,4-seco-lanostane-type triterpene, seco-coccinic acid F ( 2), along with three known dibenzocyclooctadiene lignans, isovaleroylbinankadsurin A ( 3), kadsuralignan J ( 4), and binankadsurin A ( 5), and one lanostane-type triterpene, 20( R),24( E)-3-oxo-9 beta-lanosta-7,24-dien-26-oic acid ( 6), were isolated from the methano...
متن کاملFlavonoids from Daphne aurantiaca and their inhibitory activities against nitric oxide production.
Chemical examination of the methanolic extract from the stem bark of Daphne aurantiaca led to the isolation of three new flavonoids (1-3), and 29 known flavonoids. All 32 compounds were isolated for the first time from Daphne aurantiaca. The isolates were tested for inhibitory activities against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.7 macrophages. Compounds 21...
