The objective of the study was to develop new Cyclooxygenase-2 inhibitors as anti-inflammatory agents from synthetic route.The 2-phenyl-4H-chromen-4-one and 2-phenyl-2,3-dihydro-4H-chromen-one hybrids were synthesised and characterised by using UV, IR, We investigated whether flavanones, hesperetin-naringenin, orange, and grapefruit juices reduce airway inflammation and remodeling in murine chronic asthma model. To establish chronic asthma, mice received house dust mite (HDM) for 3 days in 2 weeks, followed by twice per week for 4 weeks.
Eleven new C-geranylated flavonoids, tomentodiplacones L, M, and N (1, 2, 10), tomentodiplacol B (3), 3',4'-O-dimethyl-5'-hydroxydiplacone (4), mimulones F, G, and H (5, 6, 7), paulowniones A (8) and B (9), tomentone (11), and 3',4',5'-trimethoxyflavanone (12), together with 11 known flavonoids
A phytochemical study of the roots of Pongamia pinnata afforded 29 flavanones and flavanols, including 7 previously undescribed compounds. The structures of the isolated compounds were determined by 1D and 2D NMR and mass spectroscopy data. The absolute configurations of the compounds were assigned
A novel series of synthetic 2'-hydroxychalcones (1a-h), 2'-methoxychalcones (2a-l), flavanones (3a-k) and flavones (4a-f) have been synthesized and evaluated for their anti-inflammatory activity in carrageenan induced rat paw oedema model. Compounds 1a, 1e-g, 2e-g, 3j, and 4f showed potent
A new flavanone glycoside, (-)(2S)-5,6,7,3',5'-pentahydroxyflavanone-7-O-β-D-glucopyranoside (1), was isolated from the stems of Lippia graveolens H.B.K. (Verbenaceae). The structure of 1 was elucidated based on spectral analysis and chemical transformations. The treatment of 1 with acetic anhydride
Poncirin is flavanone derivative (isolated from Poncirus trifoliata) with known pharmacological activities such as anti-tumor, anti-osteoporotic, anti-inflammatory and anti-colitic. The present study aimed to explore the anti-allodynic and anti-hyperalgesic potentials of poncirin in Rheumatoid arthritis (RA) is closely related to the pathogenesis of tumor necrosis factor α in lesions. We investigated the suppressive effects of a Citrus flavanone naringin on inflammatory responses in mice with collagen-induced arthritis (CIA), a mouse model for RA. To investigate potential
Dietary flavonoids as popular food additives have attracted a wide range of research interests. Naringenin, a common flavanone, was evaluated of its impact on the formation of advanced glycation endproducts (AGEs) in bread crust. It was found that with the increase of naringenin content in bread
From the methanolic extract of Eysenhardtia platycarpa (leaves), were isolated the prenylated flavanones: 5,7-dihydroxy-6-methyl-8-prenylflavanone (1), 5,7-dihydroxy-6-methyl-8-prenyl-4'-methoxy-flavanone (2), 5,7-dihydroxy-6-prenylflavanone (3), 5-dihydroxy-7-methoxy-6-prenylflavanone (4),
The consumption of flavonoid-rich Citrus extracts has been associated with multiple beneficial effects including anti-inflammatory properties, but the potential effects on the inflammatory responses in the gut have not been thoroughly investigated. We used microarrays to search for molecular changes
The flavanones hesperidin, eriocitrin and eriodictyol were investigated for their prevention of the oxidative stress and systemic inflammation caused by high-fat diet in C57BL/6J mice. The mice received a standard diet (9.5% kcal from fat), high-fat diet (45% kcal from fat) or high-fat diet
2'-Hydroxy flavanone (1) was previously isolated from Mimosa pudica (L.) whole plant and was found to exhibit anti-inflammatory effects in vitro. There are also reports on anti-inflammatory properties of compounds bearing flavanone/chromone nucleus. Taking this into account, fourteen derivatives of
At the end of 2019, a novel flu-like coronavirus named COVID-19 (coronavirus disease 2019) was recognized by World Health Organization. No specific treatments exist for COVID-19 at this time. New evidence suggests that therapeutic options focusing on antiviral agents may alleviate COVID-19 symptoms
(1) Background: Many flavonoids derived from natural sources have been reported to exhibit antioxidant and anti-inflammatory effects. Our preliminary study suggested that Coreopsis lanceolata flowers (CLFs) include high flavonoid content; (2) Methods: CLFs were extracted in 80% (v/v) aqueous
