可膨胀纳米粒(ENPs)是一种很有前途的pH响应型聚合物药物载体,在多种腹膜癌模型中得到了证实。然而,以前的给药途径仅限于腹膜内注射和单一药物紫杉醇。在本研究中,我们初步评价了ENPs静脉注射后在小鼠体内的生物分布和毒性。ENPs主要定位于肝脏,在肝脏或其他关键器官没有检测到急性毒性。在这些结果的基础上,我们将FQI1包裹在ENPs中,FQI1是一种有前途的治疗肝癌的先导化合物。ENPs在体外被癌症和非癌症的人肝细胞摄取,尽管摄取率不同。携带FQI1的ENPs以pH依赖的方式释放FQI1,在体外永生化肝细胞中与未包裹FQI1的FQI1具有同等的增殖抑制作用。ENPs是一种治疗化合物的通用平台递送系统,在肝病的治疗中具有潜在的实用价值。
Expansile nanoparticles (eNPs) are a promising pH-responsive polymeric drug delivery vehicle, as demonstrated in multiple intraperitoneal cancer models. However, previous delivery routes were limited to intraperitoneal injection and to a single agent, paclitaxel. In this study, we preliminarily evaluate the biodistribution and in vivo toxicity of eNPs in mice after intravenous injection. The eNPs localize predominantly to the liver, without detectable acute toxicity in the liver or other key organs. On the basis of these results, we encapsulated FQI1, a promising lead compound for treatment of hepatocellular carcinoma, in eNPs. eNPs are taken up by cancerous and noncancerous human liver cells in vitro, although at different rates. FQI1-loaded eNPs release FQI1 in a pH-dependent manner and limit proliferation equivalently to unencapsulated FQI1 in immortalized hepatocytes in vitro. eNPs are a versatile platform delivery system for therapeutic compounds and have potential utility in the treatment of liver disease.
