AI Article Synopsis

  • Researchers created nanohybrid liposomes coated with hyaluronic acid-ceramide for delivering the anticancer drug doxorubicin (DOX) and for cancer imaging using a contrast agent called Magnevist, achieving a size of 120-130nm.
  • The new formulation improved drug release in acidic environments (like those found in tumors), and its design reduced cytotoxicity compared to traditional liposomes.
  • In animal studies, the nanohybrid liposomes showed prolonged blood circulation and enhanced cancer-targeting abilities, indicating potential for both effective cancer treatment and real-time imaging diagnostics.

Article Abstract

Nanohybrid liposomes coated with amphiphilic hyaluronic acid-ceramide (HACE) was fabricated for targeted delivery of anticancer drug and in vivo cancer imaging. Nanohybrid liposomes including doxorubicin (DOX) and Magnevist, a contrast agent for magnetic resonance (MR) imaging, with 120-130nm mean diameter and a narrow size distribution were developed. DOX release from the developed formulation was improved at acidic pH (pH5.5 and 6.8) versus physiological pH (pH7.4). Cytotoxicity induced by the blank plain liposome was reduced by coating the outer surface of the nanohybrid liposome with HACE. Cellular uptake of DOX from the nanohybrid liposome was enhanced by HA and CD44 receptor interaction, versus the plain liposome. In vivo contrast-enhancing effects revealed that the nanohybrid liposome can be used as a tumor targeting MR imaging probe for cancer diagnosis. In a pharmacokinetic study in rats, in vivo clearance of DOX was decreased in the order DOX solution, plain liposome (F2), and nanohybrid liposome (F3), indicating prolonged circulation of the drug in the blood stream and improved therapeutic efficacy of the nanohybrid liposome (F3). Based on these findings, the nanohybrid liposomal system may be a useful candidate for real-time cancer diagnosis and therapy.
