ABSTRACT
Objective To prepare RGD and TAT co-modified paclitaxel loaded liposome(RGD/TAT-LP-PTX)for A 549 cells targeting.Method The co-modified liposome was prepared by film-ultrasonic method. The appearance,particle size,Zeta potential were evaluated. The cellular uptake by A 549 cells in vitro was used to evaluate the targeting efficiency. The anti-proliferation efficiency of RGD/TAT-LP-PTX was evaluated by MTT assay. Results The particle diameter of the co-modified liposome was (118.5±11.4) nm with the Zeta potential of (21.58±2.42 )mV. The entrapment efficiency of PTX was 86.5%. The result demonstrated that the co-modified liposome uptaken by A 549 were 2.1, 2.8 times higher than that of TAT-LP and RGD-LP, respectively. The RGD/TAT-LP-PTX shows the highest anti-proliferation efficiency. Conclusion The co-modified liposome might serve as a promising tumor delivery system of antitumor drugs.
