Toxic and repellent effects of Baccharis salicifolia essential oil on Tribolium castaneum.
TLDR
Toxic and repellent effects of chemical derivatives of the major sesquiterpene present in B salicifolia essential oil, as well as a series of monoterpenes, were evaluated in order to investigate structure-activity relationships. Expand
Anti-ulcerogenic activity of xanthanolide sesquiterpenes from Xanthium cavanillesii in rats.
TLDR
It is suggested that the mechanism of protection would involve, at least in part, a nucleophylic attack of the sulfhydryl group from the biological molecules present in the gastric mucosa to electrophylic carbons accessible in suitable Michael acceptors. Expand
Evaluation of antiviral activity of aqueous extracts from Achyrocline satureioides against Western equine encephalitis virus
TLDR
It is demonstrated that aqueous extracts of A. satureioides are active against WEEV, and further studies are needed in order to identify which compounds could be responsible for this effect, and how they exert antiviral action. Expand
Electrooxidation mechanism of non-steroidal anti-inflammatory drug piroxicam at glassy carbon electrode
Abstract The electrochemical oxidation behavior of the anti-inflammatory drug piroxicam at the glassy carbon electrode in 10% ACN + 90% 0.2 M Britton–Robinson Buffer is presented. Cyclic voltammetry,Expand
Diterpenes from Laennecia sophiifolia.
From the aerial parts of Laennecia sophiifolia (Kunth) G.L. Nesom, a neo-clerodane and an acyclic furano diterpene were isolated, along with four known compounds, 2beta-hydroxyhardwickiic acid,Expand
New dammarane triterpenes from the aerial parts of Ibicella lutea grown in Argentina.
TLDR
Two new dammarane triterpenes have been isolated from the aerial parts of Ibicella lutea and were obtained along with the known compounds 20S,24S-epoxy-3beta,12beta,25-trihydroxydammarane (3) and apigenin. Expand
Chemical composition of four essential oils from Eupatorium spp: Biological activities toward Tribolium castaneum (Coleoptera: Tenebrionidae)
RESUMEN. „ Se evaluaron las propiedades toxicas y repelentes de los aceites esenciales de cuatro especies del genero Eupatorium (Asteraceae): E. buniifolium Hook. et Arn, E. inulaefolium Kunth, E.Expand
A novel icetexane diterpene, 5-epi-icetexone from Salvia gilliessi is active against Trypanosoma cruzi.
TLDR
It was concluded that ICTX is active against T. cruzi and may act by multiple mechanisms, and this novel icetexane diterpene may be a good candidate for therapeutic use against Chagas' disease. Expand
Natural Sesquiterpene Lactones are Active Against Leishmania mexicana
TLDR
The effects of 3 natural sesquiterpene lactones evaluated using cultured Leishmania mexicana promastigotes concluded that these compounds can affect the parasite's life cycle, possibly through multiple mechanisms. Expand
Novel anti-ulcer alpha,beta-unsaturated lactones inhibit compound 48/80-induced mast cell degranulation.
TLDR
The present study provides the first strong evidence in favour of the hypothesis that dehydroleucodine, xanthatin and 3-benzyloxymethyl-5H-furan-2-one inhibit compound 48/80-induced serotonin release from peritoneal mast cells, acting thus as mast cell stabilizers. Expand
