Anticancer efficacy of a novel propofol–linoleic acid-loaded escheriosomal formulation against murine hepatocellular carcinoma. (August 2013) - Khan, Azmat Ali
Aim: The preparation and characterization of a novel escheriosomal nanoparticle formulation of a potent anticancer conjugate, 2, 6-diisopropylphenol-linoleic acid (2, 6P–LA), and evaluation of its anticancer efficacy against diethyl nitrosamine-induced hepatocellular carcinoma (HCC) in BALB/c mice.Materials & methods: Escheriosomized 2, 6P–LA nanoparticles were characterized for size, zeta-potential, entrapment efficiency, release kinetics and in vivo toxicity. Their anticancer potential was evaluated on the basis of survival, DNA fragmentation, caspase-3 activation, western blot analysis of apoptotic factors and histopathological changes in hepatocytes of treated animals.Results: The escheriosomized 2, 6P–LA nanoparticles exhibited low toxicity, biocompatibility and bioavailability. As revealed by apoptosis induction, survival rate, expression profiles of Bax, Bcl-2 and caspase-9, escheriosomized 2, 6P–LA nanoparticles were more effective in the treatment of HCC than the free form of 2, 6P–LA in experimental animals.Conclusion: 2, 6P–LA-bearing escheriosome nanoparticles are effective in suppressing HCC in mice.
