Lorena R.F. de Sousa,Hongmei Wu,Liliane Nebo,João B. Fernandes,Maria Fátima das Graças Fernandes da Silva,Werner Kiefer,Manuel Kanitz,Jochen Bodem,Wibke E. Diederich,Tanja Schirmeister,Paulo C. Vieira +10 more
TL;DR: The results of this study help to understand the mechanism of inhibition of the Dengue virus serine protease by flavonoids, which is essential for the development of improved inhibitors.
Journal ArticleDOI
Activity of Ricinus communis (Euphorbiaceae) and ricinine against the leaf-cutting ant Atta sexdens rubropilosa (Hymenoptera : Formicidae) and the symbiotic fungus Leucoagaricus gongylophorus
Maria Fatima M. A. Bigi,Vera L. V. Torkomian,Suzanne T. C. S. De Groote,M. J. A. Hebling,O. C. Bueno,Fernando Carlos Pagnocca,João B. Fernandes,Paulo C. Vieira,Maria Fátima das Graças Fernandes da Silva +8 more
TL;DR: The main compounds responsible for activity against the fungus and ant in leaf extracts of R communis were found to be fatty acids for the former and ricinine for the ants.
Journal ArticleDOI
Development of a New Method To Prepare Nano-/microparticles Loaded with Extracts of Azadirachta indica, Their Characterization and Use in Controlling Plutella xylostella
Moacir Rossi Forim,Eveline Soares Costa,Maria Fátima das Graças Fernandes da Silva,João B. Fernandes,Janaina Marques Mondego,Arlindo Leal Boiça Júnior +5 more
TL;DR: A new method to prepare nanoparticles loaded with neem (Azadirachta indica) extracts is presented and the nanoparticle information improved the stability of neem products against ultraviolet radiation and increased their dispersion in the aqueous phase.
Journal ArticleDOI
