In the present study, a structured-based virtual screening (VS) of differently substituted furocoumarins and analogues has been carried out against nuclear factor kappa B (NF-κB), with the objective of selecting molecules able to inhibit the binding of this transcription factor to the DNA. The focus
Nuclear Factor kappaB (NF-κB) plays a very important role in the control of gene expression and is deeply involved in several human pathologies. Accordingly, molecules targeting NF-κB dependent biological functions are considered of great interest. Virtual screening of furocoumarin libraries against
Phytochemical and biological studies aimed at the discovery and development of novel antiinflammatory agents from natural sources have been conducted in our laboratory for a number of years. In this communication, three naturally occurring furocoumarins (imperatorin, isoimperatorin and
BACKGROUND
The synthesis of 1,2-oxazine-fused linear furocoumarins was performed involving the transition metal catalysis reaction of plant coumarin oreoselone derivatives.
OBJECTIVE
The Pd-catalyzed desulfonative cross-coupling reactions of 2-(tosyl)oreoselone with terminal alkynes and the
Pharmacological and biochemical studies on the Ammi majus seeds L. (family Umbelliferae) grown in Egypt are limited. Furocoumarins are the major constituents in the plant seeds. In the present study, the evaluation of the antihyperlipidemic, anti-inflammatory, analgesic, and antipyretic activities
The photobiological properties of three new angelicin derivatives carrying a methyl-group in 4' position at the furanic ring have been studied. In double-irradiation experiments on E. coli cells, they appeared to behave as monofunctional reactives towards DNA, similarly to the other angelicin
Phytophotodermatitis is a condition that occurs by contact with plants containing phototoxic agents such as furocoumarins and psoralens with subsequent ultraviolet exposure. Phytophotodermatitis typically presents as sharply defined erythematous patches with occasional blistering, sometimes
BACKGROUND
Angelicin is a furocoumarin found in Psoralea corylifolia L. fruit. The purpose of this study was to investigate the protective ability of angelicin against inflammation in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and LPS-induced in vivo acute lung injury model.
METHODS
The
Isoimperatorin (IMP), an active natural furocoumarin, has numerous pharmacologic effects, including anti-inflammatory, analgesic, antispasmodic, and anticancer activities. This study aimed to evaluate the preventive activity of IMP in an ovalbumin (OVA)-induced murine model of asthma and to
Angelicin, a furocoumarin found in Psoralea corylifolia L. fruit, has been reported to have anti-inflammatory activity. The purpose of this study was to determine the protective effects of angelicin on allergic asthma induced by ovalbumin (OVA) in mice. Mice were sensitized to OVA (on days 0 and 14)
Angelicin, a member of the furocoumarin group, is related to psoralen which is well known for its effectiveness in phototherapy. The furocoumarins as a group have been studied since the 1950s but only recently has angelicin begun to come into its own as the subject of several biological studies.
Renewed interest in natural products as potential source of drugs led us to investigate on both the anti-inflammatory and anti-nociceptive activity of Citrus bergamia Risso et Poiteau (bergamot) essential oil (BEO). Carrageenan-induced paw edema in rats was used as an experimental model of
Bergapten (5-methoxypsoralen, 5-MOP) is a plant-derived furocoumarin with demonstrated anti-inflammatory action. The present study investigated its effects on allergic inflammation in two related pathways of mast cell degranulation. Compound 48/80 and lipopolysaccharide (LPS) were used to activate
Shigella dysenteriae continues to be a major health problem, which leads to death, due to diarrhoea and dysentery, predominantly in children below the age of 5. Bacterial invasion of the colonic epithelium leads to severe inflammation together with bacterial dissemination generates abscesses and
A series of derivatives of 5-(aminomethyl)-8-methoxypsoralens, 8-[(3-aminopropyl)oxy]psoralens, and 5-[[[3-(tri-methylammonio)propyl]methyl]-8-methoxypsoralen has been synthesized and their potential as PUVA reagents examined. While the DNA association constants of selected psoralens were found to
