Modulating the site-specific oral delivery of sorafenib using sugar-grafted nanoparticles for hepatocellular carcinoma treatment.

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. PMID: 31254645 [PubMed - as supplied by publisher]
