Naringenin loaded multifunctional nanoparticles to enhance the chemotherapeutic efficacy in hepatic fibrosis.

Naringenin is highly potent dietary phenolic compound (Flavonoids) found as a major bioactive in citrus fruits. The low solubility of Naringenin, decreases its availability at the site of action by hindering solubility and transportation across the biological membrane. Naringenin loaded nanoparticles enhance the solubility and drug availability at site of action. Naringenin solid lipid nanoparticles were prepared by emulsification and homogenization method using GMO (glycerylmonooleate) and TPGS (Tocopheryl polyethylene glycol succinate) as co-stabilizer. Physico-chemical characterization confirmed the particles were of nanometer size, smooth and spherical morphology. The FTIR and DSC studies conforms that drug and polymers are compatible. The in-vitro study shows prolong and sustained release of Naringenin upto 90 Hrs. In-vivo studies conforms the prolonged and efficient treatment of Hepatic fibrosis. The liver enzymes and pro inflammatory cytokines in blood got significantly reversed with the rats exposed to Naringenin nanoparticle indicating reduced liver damage and fibrosis. Nanoformulation enhances the bioavailability of Naringenin and liver specific delivery of the same, which up-regulates MMP-2 hepatic proteins resulting in reduced liver fibrosis.
