Abstract
OBJECTIVES
The aim of this study was to investigate the potential of poly(amido amine) (PAMAM) dendrimer decorated graphene oxide (GO) based nanocarrier for targeted delivery of a hydrophobic anticancer drug, quercetin (QSR).
METHODS
GO-PAMAM was successfully synthesized by covalent bonding between GO and NH2-terminated PAMAM dendrimer (zero generation). To investigate drug loading performance, QSR was loaded on the surface of GO as well as GO-PAMAM. Further, the release behaviour of QSR-loaded GO-PAMAM was studied. Finally, an in-vitro sulforhodamine B assay was performed in HEK 293T epithelial cells and MDA MB 231 breast cancer cells.
KEY FINDINGS
It was observed that GO-PAMAM shows higher QSR loading capacity compared to GO. Also, synthesized nanocarrier exhibits controlled as well as pH-responsive release of QSR and the amount of QSR released at pH 4 was approximately two times higher than the release at pH 7.4. Furthermore, GO-PAMAM was found to be biocompatible for HEK 293T cells, and a high cytotoxic effect was observed for QSR-loaded GO-PAMAM on MDA MB 231 cells.
CONCLUSIONS
The present investigation highlights the potential application of synthesized hybrid materials as a nanocarrier with excellent loading and controlled releasing efficiency for the delivery of the hydrophobic anticancer drug.
