Antiallergic agents from natural sources 9. Inhibition of nitric oxide production by novel chalcone derivatives from Mallotus philippinensis (Euphorbiaceae).
Three novel chalcone derivatives were isolated from the fruits of Mallotus philippinensis MUELL and results suggest that they have anti-inflammatory and immunoregulatory effects. Expand
New lignans from Kadsura coccinea and their nitric oxide inhibitory activities.
In vitro anti-allergic screening of medicinal herbal extracts revealed that the chloroform extract of the rhizoma of Kadsura coccinea inhibited nitric oxide (NO) production in a lipopolysaccharideExpand
Triterpenoids from Hippophae rhamnoides L. and their nitric oxide production-inhibitory and DPPH radical-scavenging activities.
The chloroform-soluble fraction of the 80% acetone extract of branch bark was observed to inhibit nitric oxide (NO) production in a lipopolysaccharide and recombinant mouse interferon-gamma-activated murine macrophage-like cell line, RAW 264.7 cells. Expand
Anti-allergic agents from natural sources (4): anti-allergic activity of new phloroglucinol derivatives from Mallotus philippensis (Euphorbiaceae).
Results suggest that the novel phloroglucinol derivatives have anti-inflammatory effects. Expand
Sesquiterpene coumarins from Ferula fukanensis and nitric oxide production inhibitory effects.
Six new sesquiterpene coumarin derivatives were isolated from a 80% aqueous methanol extract of the roots of Ferula fukanensis and inhibited nitric oxide (NO) production and inducible NO synthase (iNOS) gene expression by a murine macrophage-like cell line. Expand
Sesquiterpene coumarins from Ferula fukanensis and their pro-inflammatory cytokine gene expression inhibitory effects.
Six new sesquiterpene coumarin derivatives, fukanefuromarin H-M (1-6), were isolated from an 80% aqueous methanol extract of the roots of Ferula fukanensis. The structures were elucidated on theExpand
New phenanthrenes and stilbenes from Dendrobium loddigesii.
It is suggested that this phenanthrene is a stronger inhibitor of NO production than dihydrophenanthrene, which has shown significant inhibitory activity against nitric oxide production. Expand
Neolignans from Piper futokadsura and their inhibition of nitric oxide production.
These lignans inhibited nitric oxide production by a murine macrophage-like cell line (RAW 264.7), which was activated by lipopolysaccharide and interferon-gamma. Expand
