ABSTRACT

Objective:

To prepare lactosaminated matrine liposomes and to study its targetability to liver in mice and efficacy of anti-tumor activities on human hepatoma cell line HepG2 in vitro.

Methods:

The matrine liposomes were prepared using the reverse-phase evaporation-ultrasonic technique.Lactosylphosphatidy-lethanolamine(Lac-PE) was synthesized and used for modified matrine liposomes..the diameter and entrapment efficiency of it were determined.The RP-HPLC was used for the determination of matrine concentration in mice tissue.The cytotoxic effect of LML on human hepatoma cell line HepG2 in vitro was detected by thiazolyl blue(MTT)assay.

Results:

The LML were nice and uniform,the particle diameter was between 80 and 150 nm and envelopment rats was 48.1%.Compared with matrine solution,ML and LML exhibited long circulation time.Tissue distribution results proved that the area under curve of liver was significantly difference among modified matrine liposomes,regular matrine liposomes and matrine solutions(P
