Stereochemical Revision of 2&-Hydroxytirotundin Abraham García Guillermo Delgado Multidisciplinaria (Ciencias Naturales y Exactas) 2α Tagitinins furanheliangolides Tithonia diversifolia sesquiterpene lactones A chemical study of the aerial parts of Tithonia diversifolialed to the isolation and stereostructural characterization of tagitininsA (1), C (2) and F (3), and a mixture of sterols. Tagitinin A (1) underwentspontaneous dehydration to 4 during the course of its 1H NMRmeasurement in CDCl3. The stereochemical analysis of 2α-hydroxytirotundin(5), an isomer of 1 previously reported by Kinghorn et al,led to the correction of its 3S,10S configuration to the 3S,10R stereochemistry.In addition, bioactivity evaluation of isolates showed themto exhibit moderate anti-inflammatory and cytotoxic activity 2006 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47550407 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.4 Vol.50 |
