Paper Abstract

Hepatocarcinoma, a malignant cancer, threaten human life badly. It is a current issue to seek the effective natural remedy from plant to treat cancer due to the resistance of the advanced hepatocarcinoma to chemotherapy. Berberine (Ber), an isoquinoline derivative alkaloid, has a wide range of pharmacological properties and is considered to have anti-hepatocarcinoma effects. However its low oral bioavailability restricts its wide application. In this report, Ber nanosuspension (Ber-NS) composed of Ber and D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) was prepared by high pressure homogenization technique. Both in vitro and in vivo anti-hepatocarcinoma effects of Ber-NS relative to effcacy of bulk Ber were evaluated. The particle size and zeta potential of Ber-NS were 73.1 ± 3.7 nm and 6.99 ± 0.17 mV, respectively. Ber-NS exhibited significant inhibitory effects against human HepG2 and Huh7 cells, and the corresponding IC50 values were 8.1 and 4.7 μg/ml (18.3 and 6.5 μg/ml of Ber solution). In vivo studies also showed higher antitumor efficacy, and inhibition rates was 63.7% (41.4 % of Ber solution) at 100 mg/kg intragastric administration in the H22 solid tumor bearing mice. These results suggest that the delivery of Ber as a nanosuspension is a promising approach for treating hepatocarcinoma.
