In vitro Anticancer Activity of Doxorubicin-Loading Pectin Nanoparticles
Journal Title: Journal of Pharmaceutical and Biomedical Sciences - Year 2016, Vol 6, Issue 5
Abstract
By using pectin (PEC) as carrier material and doxorubicin (DOX) as a model drug, the blank PEC nanoparticles (PEC-NPs) and the DOX-loading PEC nanoparticles (DOX-PEC-NPs) were prepared by microemulsification method and drug adsorption. The aim of this study is to investigate the anticancer activity of DOX-PEC-NPs in vitro to understand the advantages of PEC-NPs as an anticancer drug delivery system. The particle size, polydispersity index (PDI) and zeta potential of PEC-NPs were (276.80 ± 2.80) nm, (0.140 ± 0.014) and (−19.83 ± 0.21) mV, while those of DOX-PEC-NPs were (283.73 ± 3.26) nm, (0.157 ± 0.034) and (−18.00 ± 0.44) mV. The entrapment efficiency (EE%) and drug-loading rate (LR%) of DOX-PEC-NPs were (92.10 ± 0.60)% and (18.72 ± 0.10)%, respectively. Using an MTT assay, the DOX-PEC-NPs were proved to greatly inhibit the viability of MDAMB- 231 cells, A549 cells and NCI-H1299 cells, and the anticancer activity was higher than that of the DOX solution in these cells. The PEC-NPs had no cytotoxicity against the three tested cells. An inverted fluorescence microscope and flow cytometry were used to observe the intracellular uptake of DOX. The DOX-PEC-NPs resulted in faster and more DOX uptake than DOX solution in the tested cells. The results indicated that the PEC-NPs may be a potential anticancer drug delivery system which could reduce the dose and increase the activity of anticancer drugs.
