Lindera Obtusiloba

Eight phenolic glycosides, tachioside (1), isotachioside (2), koaburaside (3), 2,6-dimethoxy-4-hydroxyphenyl-1- O-ß-D-glucopyranoside (4), 4,6-dihydroxy-2- methoxyphenyl-1- O-β-D-glucopyranoside (5), a mixture of erigeside C (6a) and salidroside (6b), and 6-hydroxyphenyl)-1- O-β-D-glucopyranoside (7) were isolated from the stems of Lindera obtusiloba Blume. The structures of the isolates were determined by 1H-, 13C-NMR, COSY, HMQC, and HMBC spectroscopy. To evaluate their anti-allergic inflammatory activities, the inhibitory effects of isolates (1-7) on histamine release and on the gene expressions of tumor necrosis factor (TNF)-α and interleukin (IL)-6 were examined using human mast cells; previous studies have reported that TNF-α and IL-6 release from mast cells is positively related to the severity of allergic symptoms. Of the tested compounds, koaburaside (3), 2,6-dimethoxy-4-hydroxyphenyl-1- O-ß-D- glucopyranoside (4), and (6-hydroxyphenyl)-1- O-β-D-glucopyranoside (7) suppressed histamine release from mast cells as compared with gallic acid (positive control). In particular, 6-hydroxyphenyl)-1- O-β-D-glucopyranoside (7) attenuated the gene expressions of the proinflammatory cytokines TNF-α and IL-6 in human mast cells. Our results support the notion that phenolic glycosides isolated from L. obtusiloba inhibit mast-cell-derived allergic inflammation, histamine, and proinflammatory cytokines.

A methanol extract of the seed of Prunus persica (Rosaceae) was found to inhibit histamine release in human mast cells. Activity-guided fractionation of the methanol extract yielded three cyanogenic glycosides (1–3) and other phenolic compounds (4–8). To evaluate their anti-allergic and anti-inflammatory activities, the isolates (1–8) were tested for their inhibitory effects on histamine release and on the gene expressions of tumor necrosis factor (TNF)-α and interleukin (IL)–6 in human mast cells. Of these, phenolic glycosides 7 and 8 suppressed histamine release and inhibited the pro-inflammatory cytokines TNF-α and IL-6. These results suggest that isolates from P. persica are among the anti-allergic inflammatory principles in this medicinal plant.

Allergic inflammatory diseases such as food allergy, asthma, sinusitis, and atopic dermatitis are increasing worldwide. In this study, we investigated the effects of aqueous extract of Mosla chinensis Max. (AMC) on mast cell-mediated allergic inflammation and studied the possible mechanism of this action. AMC inhibited compound 48/80-induced systemic and immunoglobulin E (IgE)-mediated local anaphylaxis. AMC reduced intracellular calcium levels and downstream histamine release from rat peritoneal mast cells activated by compound 48/80 or IgE. In addition, AMC decreased gene expression and secretion of proinflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-8 in human mast cells. The inhibitory effect of AMC on cytokine expression was nuclear factor (NF)-κB dependent. Our results indicate that AMC inhibits mast cell-mediated allergic inflammatory reaction by suppressing histamine release and expression of proinflammatory cytokines and the involvement of calcium and NF-κB in these effects. AMC might be a possible therapeutic candidate for allergic inflammatory disorders.

Activity-guided isolation of compounds from the fruits of Amomum xanthioides resulted in the purification of fourteen phenolic compounds, 4-hydroxy-benzaldehyde (1), 3,4-dihydroxybenzaldehyde (2), 3,5-dimethoxy-4-methylbenzaldehyde (3), syringic aldehyde (4), benzoic acid (5), 3,4-dihydroxy benzoic acid (6), vanillic acid (7), 3-hydroxy-2-methoxybenzoic acid (8), o-vanillic acid (9), phenylacetic acid (10), tyrosol (11), pyrocatechol (12), 1,2,4,5-tetramethoxybenzene (13), and 3,3′,5,5′-tetramethoxybiphenyl-4,4′-diol (14). To evaluate the anti-allergic inflammatory activities of these compounds, we examined the inhibitory effects of the isolates (1-14) on histamine release and on the expressions of tumor necrosis factor (TNF)-α and interleukin (IL)–6 genes by using human mast cells. Of the tested compounds, 9, 11, and 13 suppressed histamine release from mast cells, and all isolates attenuated the expressions of the pro-inflammatory cytokines, TNF-α and IL-6 genes in human mast cells.

A phthalide, levistolide A (1), and six coumarins, demethylsuberosin (2), fraxetin (3), (-)-marmesinin (4), 3'( S)- O-β-D-glucopyranosyl-3’,4'-dihydroxanthyletin (5), 3'( R)- O-β-D-glucopyranosyl-3’,4'-dihydroxanthyletin (6), and isopraeroside IV (7) were isolated from the methanolic extract of the roots of Angelica tenuissima Nakai. Their chemical structures were confirmed by comparing spectroscopic and reported data. All seven compounds were isolated for the first time from this plant source. The anti-allergic activities of compounds 1-7 were examined using human mast cells, and compounds 1-3 at 10 μM potently suppressed IL-6 expression and inhibited histamine release from human mast cells by more than 30%.
