(±)-Licarina-A loaded PLGA nanoparticles: Preparation and in vitro schistosomicidal activity for controlled release
The aim of this work was incorporation of (±)-licarina-A 1 into the PLGA particles were carried out by emulsion/solvent evaporation method. The obtained particles were centrifuged and dried out by lyophilization. The nanoparticles were characterized by FESEM and the amount of 1 was quantified by UV-Vis spectroscopy. Preliminary bioassay results indicate that 1 possesses in vitro schistosomicidal activity against adult worms couples of Schistosoma mansoni at 200µM, leading to 100% of couples separation and completely motor activity reducing. In vitro schistosomicidal activity of (±)-licarina-A-loaded PLGA nanoparticles are in progress in order to elucidate a possible improved and prolonged schistosomicidal action.
