摘要: Carrier with high drug loading content is one of the most important issues in delivery system. In present work, an ion-pair amphiphilic molecule composed anticancer cation and surfactant anion used for straightforward fabricating vesicles cancer therapy. Anticancer (cytarabine hydrochloride) anionic (AOT) are selected fabrication molecule. One contains cation, thus 50% (mol/mol) theory. The vitro release study shows that time cytarabine about 3 times pure solution permeability has been improved 160 tested by parallel artificial membrane assay model. However, hemolytic toxicity largely decreased studied concentration range. cytotoxicity results show cytarabine-AOT amphiphiles have a much lower IC50 (drug resulting cell death) value higher inhibition rate comparing their respective components, indicating its effective therapy leukemic cells. To obtain longer convenient system, prepared further incorporated into thermosensitive PLGA-PEG-PLGA hydrogel to prepare subcutaneous administration. vivo indicate vesicle-loaded good injectable system controlled
