Nicolau, Lucas Antonio Duarte; Carvalho, Nathalia S.; Pacífico, Dvison M.; Lucetti, Larisse T.; Aragão, Karoline Sabóia; Véras, Leiz M.C.Objective This study aimed to investigate the protective effect of epiisopiloturine hydrochloride (EPI), an imidazole alkaloid, on NAP-induced gastrointestinal damage in rats. Methods Initially, rats were pretreated with 0.5% carboxymethylcellulose (vehicle) or EPI (3, 10 and 30 mg/kg, p.o. or i.p., groups 3–5, respectively) twice daily, for 2 days. After 1 h, NAP (80 mg/kg, p.o.) was given. The control group r...
Anthelmintic, Antibacterial and Cytotoxicity Activity of Imidazole Alkaloids fr...
Rocha, Jefferson A.; Andrade, Ivanilza M.; Véras, Leiz M.C.; Quelemes, Patrick V.; Lima, David F.; Soares, Maria J.S.; Pinto, Pedro L.S.; Mayo, Simon J.Pilocarpus microphyllus Stapf ex Wardlew (Rutaceae), popularly known as jaborandi, is a plant native to the northern and northeastern macroregions of Brazil. Several alkaloids from this species have been isolated. There are few reports of antibacterial and anthelmintic activities for these compounds. In this work, we report the antibacterial and anthelmintic activity of five alkaloids found in P. microphyllus l...
Layer-by-layer films containing peptides of the Cry1Ab16 toxin from Bacillus th...
Plácido, Alexandra; Farias, Emanuel Airton de Oliveira; Marani, Mariela M.; Vasconcelos, Andreanne G.; Mafud, Ana C.; Mascarenhas, Yvonne P.Cry1Ab16 is a toxin of crystalline insecticidal proteins that has been widely used in genetically modified organisms (GMOs) to gain resistance to pests. For the first time, in this study, peptides derived fromthe immunogenic Cry1Ab16 toxin (from Bacillus thuringiensis) were immobilized as layer-by-layer (LbL) films. Given the concern about food and environmental safety, a peptide with immunogenic potential, PcL...
