PLGA encapsulation effect on Bioquin-HMPAO: radiolabeling and in vitro behaviour on brain and lung cancer cells
WOS: 000383579900016Bioquin-HMPAO (BH) was previously investigated as a novel brain imaging agent by in vivo biodistribution studies. Present studies are carried out to explore radiolabeling and in vitro behaviour evaluation of poly (lactic-co-glycolic acid) (PLGA) encapsulated BH nanocapsules (BH-PLGA NCs). BH-PLGA NCs were characterized utilizing dynamic light scattering and scanning electron microscope. Encapsulation effect on radiolabeling with Tc-99m was examined by stability and lipophilicity studies and effect on in vitro behaviour of Tc-99m-BH was evaluated by incorporation studies on DAOY, U87-MG and A549 cells. It is observed that PLGA encapsulation has a positive and reinforcement effect.Ege University Research FundEge University [2011 NBE 003]Current work is supported by Ege University Research Fund (contract no 2011 NBE 003).
