Abstract
Based on our previous work on the PLGA nanoparticles modified with biotinylated chitosan (Bio-CS-PLGA NPs), we further studied the stability, toxicity, pharmacokinetics, and in vivo efficacy. The safety of NPs was studied through single-dose toxicity test in mice, and the result showed that NPs were well tolerated at the dose of 300 mg/kg. Compared with the free EPB group, the NPs group exhibited higher plasma drug concentration, longer half-life time. EPB-loaded NPs significantly inhibited the tumor growth compared to free EPB. All results suggested that Bio-CS-PLGA NPs were stable, safe, and showed a promising potential on targeted drug delivery.
