The cyclohexenyl chalcone derivative [(-)-hydroxypanduratin A], together with the previously known panduratin A, sakuranetin, pinostrobin, pinocembrin, and dihydro-5,6-dehydrokawain were isolated from the chloroform extract of the red rhizome variety of Boesenbergia pandurata (Robx.) Schltr.
Some chalcones are known to be phototransformed in a solution from trans into cis isomers. 3-Hydroxy-3'-methylchalcone (3'Me-3-C) has been found to be isomerized from trans into cis by irradiation of daylight in the methanolic solution. The presence of a hydroxyl in the 2'- or 4-position in the
The synthesis of 1,3-diaryl propen-1-ones (chalcones) by the Claisen-Schmidt condensation between acetophenones and benzaldehydes in potassium hydroxide/methanol medium at room temperature yielded: 1-(4-nitrophenyl)-3-(2,4,6-trimethoxyphenyl)propen-1-one (3a),
Skin exposure to ultraviolet B (UVB) irradiation has increased significantly in recent years due to ozone depletion, and it represents the main cause of many skin diseases. Hesperidin methyl chalcone (HMC) is a compound used to treat vascular diseases that has demonstrated anti-inflammatory
Gouty arthritis is characterized by an intense inflammatory response to monosodium urate crystals (MSU), which induces severe pain and reduction in the life quality of patients. Trans-Chalcone (1,3-diphenyl-2-propen-1-one) is a flavonoid precursor presenting biological activities such as
The present work showed analgesic and antiinflammatory activities from a fraction containing three dimeric chalcones (chalcone enriched fraction - CEF), isolated from the stem-bark ethyl acetate extract of Myracrodruon urundeuva Allemao (Anacardiaceae). M. urundeuva is a popular medicinal plant used
Chalcones of 2a-f and their corresponding products, pyrazolines 3a-f, were synthesized and evaluated for their anti-inflammatory activity against carrageenan edema in albino rats at a dose of 10 mg/kg. All the compounds of this series showed promising anti-inflammatory activity. The most active
A series of novel conjugates with ursolic acid core and different chalcone ligands were synthesized via ursolic acid, 4-hydroxyacetophenone and aromatic aldehydes. All of the conjugates were confirmed by the application of IR, (1)H NMR, (13C) NMR and HR-MS. The anti-inflammatory effect was observed
Chalcone (1,3-diarylprop-2-en-1-one) derivatives have been introduced as selective cyclooxygenase-2 inhibitors. In the present study, anti-nociceptive and anti-inflammatory effects of eight novel compounds were evaluated in male mice and Wistar rats by using the writhing and formalin-induced paw
A group of novel nitric oxide (NO) donating chalcone derivatives was prepared by binding various amino chalcones with different NO donating moieties including; nitrate ester, oximes and furoxans. Most of the prepared compounds showed significant anti-inflammatory activity using carrageenan-induced
Abstract A series of novel pyrazole-based chalcones have been designed, synthesized from 1-methyl-5-(2,4,6-trimethoxyphenyl)-1H-pyrazole (6). The structures of regioisomers 6 and 7 were determined by 2D (1)H-(1)H COSY, (1)H-(13)C HSQC and (1)H-(13)C HMBC experiments. The newly synthesized compounds
Hesperidin methyl chalcone (HMC) is a safe flavonoid used to treat chronic venous diseases, but its effects and mechanisms on UVB irradiation-induced inflammation and oxidative stress have never been described in vivo. Thus, the purpose of this study was to evaluate the effects of systemic
OBJECTIVE
Mast cell and neutrophil degranulations are the important players in inflammatory disorders. Combined with potent inhibition of chemical mediators released from mast cells and neutrophil degranulations, it could be a promising anti-inflammatory agent. 2',5'-Dihydroxychalcone has been
We explored the effects of compound 33, a synthetic chalcone derivative with antioxidant activity, on lipopolysaccharide (LPS)-induced acute lung injury (ALI). Compound 33, dexamethasone or vehicle was administered intragastrically to mice 6 h before intratracheal instillation of LPS. After 24 h,
BACKGROUND
Non-steroidal anti-inflammatory drugs (NSAIDs) can result in peptic ulcer disease (PUD) which is a common condition worldwide. The aim of this study was to evaluate the antiulcer properties of (1-(4-hydroxy-phenyl)-3-m-tolyl-propenone) (HPTP) chalcone in rats using indomethacin as
