Globally, one in six deaths is reported due to cancer suggesting the critical need for development of advanced treatment regimens. In this study, solid lipid nanoparticles (SLN) were prepared and appended with polyethylene glycol (PEGylated) galactose and a multikinase inhibitor sorafenib (SRFB) was used as chemotherapeutic drug, for treating hepatocellular carcinoma (HCC). The nanoparticles were evaluated for in-vitro and in-vivo performances to showcase the targeting efficiency and therapeutic benefits of the sorafenib loaded ligand conjugated nanoparticles (GAL-SSLN). When compared with SRFB or Sorafenib loaded SLN, GAL-SSLN showed superior cytotoxicity and apoptosis in HepG2 (human hepatocellular carcinoma cells). In addition, in-vivo pharmacokinetics and real time biodistribution studies in BALB/c mice showed that the surface conjugation of nanoparticles with galactose resulted in better pharmacokinetic performance and targeted delivery of the nanoparticles to liver. Results indicated that GAL-SSLN showed promising attributes in terms of targeting sorafenib to liver and therapeutic efficacy.
全球有六分之一的死亡是由癌症报告的,这表明迫切需要开发先进的治疗方案。在这项研究中,制备了固体脂质纳米粒 (SLN),并将其与聚乙二醇 (PEGylated) 半乳糖缀合,并用多激酶抑制剂索拉非尼 (SRFB) 作为化疗药物,用于治疗肝细胞癌 (HCC)。评估了纳米粒的体外和体内性能,以展示载有索拉非尼的配体偶联纳米粒 (GAL-SSLN) 的靶向效率和治疗益处。与 SRFB 或载有索拉非尼的 SLN 相比,GAL-SSLN 在 HepG2(人肝癌细胞)中显示出更高的细胞毒性和细胞凋亡。此外,在 BALB/c 小鼠中的体内药代动力学和实时生物分布研究表明,纳米粒表面与半乳糖缀合导致更好的药代动力学性能和纳米粒向肝脏的靶向递送。结果表明,GAL-SSLN 在靶向索拉非尼到肝脏和治疗效果方面具有有前景的特性。
