Cu2O spheres as an efficient source of catalytic Cu(I) species for performing a...
Rodrigues, Thenner S.; Silva, Anderson G.M. da; Oliveira, Lucas C. de; Silva, Adalberto M. da; Teixeira, Róbson R.; Camargo, Pedro H.C.We report herein the high yield synthesis of Cu2O spheres displaying well-defined shapes and monodisperse sizes that could be employed as the source of highly catalytic active Cu(I) species towards click reactions between several of alkynes and azides to produce a variety of 1,2,3-triazoles under ligand-free and ambient conditions (in an open reactor). The utilization of Cu2O spheres enabled superior performanc...
In vitro trypanocidal evaluation of pinane derivatives from essential oils of r...
Sartorelli, Patricia; Santana, Jefferson S.; Guadagnin, Rafael C.; Lago, João Henrique G.; Pinto, Érika G.; Tempone, André G.; Stefani, Hélio A.Essential oils of ripe fruits from Schinus terebinthifolius (Anacardiaceae), obtained using a pilot extractor and a Clevenger apparatus were chemically characterized. Due the high amount of (-)- α-pinene in both oils, this monoterpene was tested against the protozoan parasite Trypanosoma cruzi, showing a moderate potential (IC50 63.56 µg/mL) when compared to benznidazole (IC50 43.14 µg/mL). Otherwise, (-)- α-pi...
Assessing the chemical composition and antimicrobial activity of essential oils...
Santos, Nara O. dos; Mariane, Bruna; Lago, João Henrique G.; Sartorelli, Patricia; Rosa, Welton; Soares, Marisi G.; Silva, Adalberto M. daThe chemical composition and antimicrobial activity of essential oils obtained from three Brazilian plant species—leaves and branches of Eremanthus erythropappus (Asteraceae), leaves of Plectranthus barbatus, and leaves of P. amboinicus (Lamiaceae)—were determined. Analysis by GC/MS and determination of Kovats indexes both indicated δ-elemene (leaves—42.61% and branches—23.41%) as well as (−)-α-bisabolol (leave...
