Abstract
The present study discusses lactose-acyclovir-N-succinyl chitosan nanoparticles (Lac-N-Suc-CSNP) using lactose as an asialoglycoprotein receptor (ASGPR) ligand for hepatic parenchymatic cells targeting. For this purpose, N-succinyl chitosan nanoparticles (N-Suc-CSNP) were prepared previously by ionotropic gelation method and lactose was conjugated to the free amino terminal group of chitosan. Lactose conjugation with N-Suc-CSNP was confirmed by FT-IR and zeta potential measurements. The Lac-N-Suc-CSNP obtained were characterized for their morphology, particle size, polydispersity index, and zeta potential. The Lac-N-Suc-CSNP showed spherical in shape with 220.3 ± 5.0 nm size range, +4.1 ± 0.2 mV zeta potential, 62.5 ± 1.2 % acyclovir entrapment efficiency and showed 27.3 ± 0.9 % cumulative acyclovir release up to 72 h. The acyclovir concentration from Lac-N-Suc-CSNP was found to be 19.9 ± 1.62 μg/g after 24 h administration revealed remarkably targeting potential to the hepatocytes and keep at a high level during the experiment. These results suggest that Lac-N-Suc-CSNP are potentially vector for hepatocytes targeting.
