Objective: To investigate the preparation technology of compound temozolomide liposomes,and its anti-tumor effect in vitro. Methods: The compound temozolomide liposomes were prepared by thin film dispersion method and the formulation was optimized. The particle size and Zeta potential of liposomes were characterized.The anti-proliferation effect of the liposomes on C6 glioma cells was investigated by the method of sulforhodamine B( SRB). Results: The encapsulation efficiencies were( 20. 87 ± 0. 22) % and( 8...
