coumarin/inflammation

Sets of coumarinyl ethers having chromone, benzofuranyl and 4-hydroxy coumarins (4, 5, 6) were prepared and tested for analgesic and antiinflammatory activity. The 4-(4'-acetyl-3'-hydroxy-phenoxymethyl)-coumarin 3 were synthesised by the reaction of 4-bromo methyl coumarin with 2, 4-dihydroxy

Three new coumarin derivatives, 8-formylalloxanthoxyletin (1), avicennone (2), and (Z)-avicennone (3), have been isolated from the stem bark of Zanthoxylum avicennae (Z. avicennae), together with 15 known compounds (4-18). The structures of these new compounds were determined through spectroscopic

BACKGROUND Cytochrome P450 (CYP) plays a key role in the metabolism of coumarin anticoagulants and nonsteroidal anti-inflammatory drugs (NSAIDs). Because CYP2C9 is a genetically polymorphic enzyme, genetic variability could play an important role in the potential interaction between NSAIDs and

One new coumarin, 3,5-dihydroxy-7-O-α-L-rhamno pyranosyl-2H-chromen-2-one (1), was isolated from the whole plant of Sarcandra glabra. The structure was elucidated by spectroscopic methods. Our results indicated that 1 significantly inhibit nitric oxide (NO) production in LPS-induced RAW264.7

Coumarin and its derivatives are fragrant natural compounds isolated from the genus Murraya that are flowering plants widely distributed in East Asia, Australia, and the Pacific Islands. Murraya plants have been widely used as medicinal herbs for relief of pain, such as headache, rheumatic pain,

Soulattrolide is a natural coumarin synthesized by the leaves of species of Calophyllum (Calophyllaceae) rain forest trees, including the American C. brasiliense, and the Asian C. teysmanii. Soulattrolide is a potent inhibitor of the reverse transcriptase from HIV-1 (RT-HIV-1), and active against

The ethyl acetate extract of leaves of Murraya paniculata (L.) Jack was described in the previous in vitro study on the inhibition effect on the growth of periodontopathic bacteria and the reduction of cytokines from LPS-stimulated macrophages. In this study, four coumarins including murrangatin

Coumarin Schiff-bases (CSB) possessing different substituents on the 4-methyl-2-substituted phenyl imino-2H-chromene-7-ol molecule were evaluated for their in-vitro antioxidant and plausible anti-inflammatory potential. The antioxidant studies of selected CSB were carried out by determining their

Coumarins represent an important class of phenolic compounds with multiple biological activities, including inhibition of lipidic peroxidation and neutrophil-dependent anion superoxide generation, anti-inflammatory and immunosuppressor actions. All of these proprieties are essential for that a drug

4-methylesculetin (4 ME) is a natural antioxidant coumarin with protective effects on the intestinal inflammation, in which oxidative stress plays a key role in its aetiology and pathophysiology. Based on this, we examined the antioxidant molecular mechanisms involved in the intestinal

A series of coumarin analogs, designed and synthesised as potential fluorescent zinc probes were evaluated for their biological activity as anti-inflammatory and antioxidant agents. The effect of the synthesised compounds on inflammation, using the carrageenin-induced rat paw oedema model, was

The promising activity of coumarin derivatives as anti-inflammatory agents has motivated us to synthesize a new series of coumarin derivatives aiming to improve the anti-inflammatory activity and/or bioavailability. In the present work, the reaction between compound III and different aromatic acyl

Fibromyalgia is a refractory syndrome characterized by chronic wayward pain and complex co-morbid psychological trepidation. The current treatments have a limited role and proper clinical benefits are far from satisfactory. Naturally occurring coumarins such as osthole are known to have analgesic

BACKGROUND Osteoarthritis is a joint disorder characterized by articular cartilage degradation leading to joint stiffness and pain. The present study investigated the effect of hydroxypyridinone-coumarin on proliferation of chondrocytes. MATERIAL AND METHODS Chondrocyte proliferation was assessed by

The interest towards coumarin-based structures stems from their polypharmacological profile. Herein, we present a series of Mannich bases and 7-azomethine-linked coumarin derivatives exhibiting antiplatelet and antithrombotic activities, in addition to the already known anti-inflammatory and
