lignan/inflammation

Evidence from the literature suggests that dietary flaxseed lignans have the ability to modulate inflammation, which is recognized as the underlying basis of multiple chronic human diseases in older adults. Our objective was to determine the effects of oral lignan supplementation on biochemical and

OBJECTIVE The fruits of Forsythia koreana have long been used in Chinese medicine to treat inflammatory disorders. However, the pharmacological data is not sufficient to clearly establish a scientific rationale for the anti-inflammatory medicinal use of this plant material, and the search for its

Suppression of pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) along with nitric oxide reduction in RAW 264.7 cells by 7,8-dihydroxy-4-methylcoumarin, ethyl p-coumarate, ethyl caffeate and ethyl ferulate drove us to search structural-analogues of the aforementioned compounds through

A new tetrahydrofuran-type lignan, episesaminone (1), was isolated from Asarum heterotropoides Fr. Schmidt var. mandshuricum (Maxim.) Kitag. Its structure was established by spectroscopic techniques (HR-MS, 1D NMR, 2D NMR, and circular dichroism). The anti-inflammatory activity in RAW 264.7

Cubebin, a dibenzylbutyrolactone lignan isolated from the crude hexane extract of the leaves of Zanthoxyllum naranjillo, showed a significant anti-inflammatory activity by using the paw edema induced by carrageenin in rats, but did not provide a significant reduction in the cell migration for the

Coptis japonica Makino (Ranunculaceae) is known to possess several biological activities such as anti-inflammatory effects. In this study, five lignans, isolariciresinol (1), lariciresinol glycoside (2), pinoresinol (3), pinoresinol glycoside (4) and syringaresinol glycoside (5), isolated from the

This study assessed the anti-inflammatory effect of the extracts and purified lignans obtained from Phyllanthus amarus. Given orally, the hexane extract (HE), the lignan-rich fraction (LRF), or the lignans phyltetralin, nirtetralin, niranthin, but not hypophyllanthin or phyllanthin, inhibited

This study investigated the anti-allodynic and anti-oedematogenic effects of the hexanic extract, lignan-rich fraction and purified lignans from a plant used in the traditional medicine, Phyllanthus amarus, in the inflammatory and neuropathic models of nociception. The hexanic extract inhibited the

Chemical investigation of Vitex negundo seeds afforded four new lignans, including a phenylindene-type lignan, vitexdoin F (1), and three phenylnaphthalene-type lignans, vitexdoins G, H and I (2-4). Their structures were elucidated by detailed spectroscopic analyses on the basis of NMR, IR, and MS

Schisandra Fructus (SF) is a traditional Chinese herb used in the treatment of inflammatory disorders like hepatitis. One of the main anti-inflammatory components of SF is the lignans. However, the underlying anti-inflammatory mechanism of Schisandra Chinensis lignans (SCL) remains unclear.

Root preparations of Krameria lappacea (Dombey) Burdet et Simpson are traditionally used against oropharyngeal inflammation. Besides antimicrobial and astringent procyanidines, lignan derivatives, including ratanhiaphenol I, II, III and (+)-conocarpan, contribute to the activity of Ratanhiae radix,

One new lignan, loniceralanside A (1), together with three known compounds (2-4), were purified from Lonicerae Japonicae Flos. Their structures were determined by HR-ESI-MS, 1 D and 2 D NMR data. Compounds 2-4 were separated from the plant for the first time. The biological test showed that compound

The wide range of inflammation mechanisms under control by NF-κB makes this pathway as an attractive target for new anti-inflammatory drugs. Herein, we showed that a new dibenzocyclooctadiene lignan analog XLYF-104-6, with a chemical name of 1,2,3,10,11-pentamethoxydibenzocycloocta-6,7-[c]

The stems of Zea mays L., otherwise known as cornstalks, were extracted with 80 % aqueous MeOH, and the concentrated extract was successively partitioned with ethyl acetate (EtOAc), normal butanol, and water. From the EtOAc fraction, a new lignan along with three known flavonoids, tricin (1),

The present paper reports the results of the methanol extract of Haplophyllum hispanicum Spach on single or repeated local 12-O-tetradecanoylphorbol acetate (TPA) administration and in the oxazolone-induced contact-delayed hypersensitivity mouse ear edemas. Two topical anti-inflammatory aryl
