Geranylated flavanones from Paulownia coreana and their inhibitory effects on nitric oxide production.
The activity-guided fractionation of the MeOH extract of the flower of Paulownia coreana led to the isolation of a new geranylated flavanone, 3'-O-methyl-5'-hydroxydiplacol (1), along with 10 known compounds (2-11). Their structures were determined using spectroscopic techniques, which included one and two dimensional (1- and 2D)-NMR. Among the isolates, compounds 1-6 showed potent inhibitory a...
متن کاملPolyphenols from Sophora yunnanensis, and their inhibitory effects on nitric oxide production.
A new flavonoid, (2R,3R)-3,7,4'-trihydroxy-3',5'-dimethoxyflavanone, named sophorayunnanol (1), together with eight known polyphenols (2-9), were isolated from the roots of Sophora yunnanensis C.Y.MA (Leguminosae). The structure including absolute stereochemistry of 1 was determined by spectroscopic (high resolution (HR)-MS, 1D- and 2D-NMR, and circular dichroism (CD)) methods. The inhibitory a...
متن کاملFive withanolides from the leaves of Datura metel L. and their inhibitory effects on nitric oxide production.
Four new withanolides named dmetelins A-D (compounds 1-4), along with the known compound 7α,27-dihydroxy-1-oxo-witha-2,5,24-trienolide (5) were isolated from the leaves of Datura metel L. (Solanaceae). Their structures were elucidated on the basis of detailed analysis of 1D and 2D NMR and mass spectrometry data. All the compounds were evaluated for their inhibitory effects on lipopolysaccharide...
متن کاملEffect of Neutrophils on Nitric Oxide Production from Stimulated Macrophages
Background: During the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. This is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. Arginase competes with inducible nitric oxide synthase for a common substrate L-arginine. Objective: To investigate whethe...
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...
