Further purification of the apolar extracts of the sponge Plakinastrella mamillaris, afforded a new oxygenated polyketide named gracilioether K, together with the previously isolated gracilioethers E-G and gracilioethers I and J. The structure of the new compound has been elucidated by extensive NMR (H-1 and C-13, COSY, HSQC, HMBC, and ROESY) and ESI-MS analysis. With the exception of gracilioether F, all compounds are endowed with potent pregnane-X-receptor (PXR) agonistic activity and therefore represent a new chemotype of potential anti-inflammatory leads. Docking calculations suggested theoretical binding modes of the identified compounds, compatible with an agonistic activity on hPXR, and clarified the molecular basis of their biological activities.

Anti-inflammatory activity of propolis extracts: a review
Provedor de dados: 79
Autores: Almeida,E. C. de; Menezes,H.
Since primeval times, the inflammatory process has been described in many different ways. Several anti-inflammatory therapies have been used in different biological models. However, in a recent "back to nature move", modern man is searching for natural products with medicinal properties, particularly those obtained from plants and bees. Propolis has been used in folk medicine for a very long time. The many compounds present in propolis require investigation.Physical-chemical analysis studies have not sufficiently established quality standards of propolis containing products. These standards should depend especially on their different pharmacological activities. There are few studies reporting on the in vitro anti-inflammatory activity of propolis...

Provedor de dados: 80
Autores: Queiroz,J. C. F.; Teixeira,C. F. P.; Lebrun,I.; Spencer,P. J.; Zucchi,T. M. A. D.
Total RNA from lipopolysaccharide (LPS)-stimulated rat macrophages used to treat protoplasts from an Aspergillus nidulans strain originated the RT2 regenerated strain, whose culture supernatant showed anti-inflammatory activity in Wistar rats. The protein fraction presenting such anti-inflammatory activity was purified and biochemically identified. The screening of the fraction responsible for such anti-inflammatory property was performed by evaluating the inhibition of carrageenan-induced paw edema in male Swiss mice. Biochemical analyses of the anti-inflammatory protein used chromatography, carbohydrates quantification of the protein sample, amino acids content analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Total sugar...

Provedor de dados: 42
Autores: Barros,Wander M.; Rao,Vietla S.N.; Silva,Regilane M.; Lima,Joaquim C.S.; Martins,Domingos T.O.
Bowdichia virgilioides H.B.K stem bark (Fabaceae), locally known as "sucupira-preta", is a reputed folk-remedy to treat some inflammatory disorders. To validate its traditional claim, the ethanolic extract from B. virgilioides was evaluated in several animal models of inflammation and nociception. The extract at oral doses of 100 to 1000 mg/kg body weight caused a significant inhibition of carrageenan-induced hind paw oedema, suppression of exudate volume and leukocyte immigration in rat pleurisy induced by carrageenan, and reduction of granuloma weights in the model of subcutaneous granulomas promoted by cotton pellets. In addition, the plant extract significantly inhibited the vascular permeability increase induced by intraperitoneal acetic acid. It also...
