    Isoliquiritigenin (ISL) has a great variety of pharmacological effects especially liver cancer therapy, but its poor solubility, bioavailability and liver targeting have limited its clinical use. In order to solve the aforementioned shortcomings, the TPGS-modified proliposomes loaded with ISL (ISL-TPGS-PLP) was prepared in this study. ISL-TPGS- PLP was fabricated via thin-film dispersion method and was characterized by the appearance, particle size, zeta potential and morphology. HPLC was used to evaluate entrapment efficiency (EE), in vitro release and stability of ISL-TPGS-PLP single or combined while appropriate physicochemical parameters were measured with DLS. Meanwhile, the pharmacokinetics and tissue distribution were also studied after oral administration. The results demonstrated that ISL-TPGS-PLP had a mean size of 23.8 +/- 0.9 nm, high EE of 97.33 +/- 0.40%. More importantly, nearly 90% ISL was released from ISL-TPGS-PLP within 24 h while only 50% was released from ISL suspension. In the pharmacokinetics study, the area under the curve (AUC(0-24h)) of ISL-TPGS-PLP was 1.53 times higher than that of ISL suspension. The Tissue distribution study showed that the ISL released from ISL-TPGS-PLP was higher in the liver than the free ISL suspension. Altogether, ISL-TPGS-PLP could ameliorate the ISL solubility, bioavailability and liver targeting ability, suggesting that ISL-TPGS-PLP could serve as a promising nanocarrier for liver cancer therapy.
