Kiwi-derived Extracellular Vesicles for Oral Delivery of Sorafenib

In this study, kiwifruit-derived extracellular vesicles (KEVs) were isolated and purified from kiwifruit, and their natural hepatic accumulation properties were exploited for targeted delivery of sorafenib (KEVs-SFB). Evidence showed that encapsulation of KEVs reduced the leakage of sorafenib in the gastrointestinal environment and enhanced the ability to cross the intestinal epithelium; KEVs-SFB was able to achieve liver accumulation and was predominantly taken up by HepG2 cells; KEVs-SFB was effective in inhibiting 4T1 cell proliferation; in the orthotopic liver cancer model, oral administration of KEVs-SFB inhibited tumor growth and improved the side effects of SFB. This PDEVs-based oral drug delivery platform is important for improving oral bioavailability and reducing drug side effects.PMID:37821012 | DOI:10.1016/j.ejps.2023.106604
