| In the present research, we prepared new glycodendrimer containing β-cyclodextrin (β-CD) in three steps. At
first, graphene quantum dots (GQDs) synthesized through pyrolysis of the citric acid (CA). Then the polyamidoamine
(PAMAM) dendrimer was grown from the surface of the modified GQDs (GQDs-PAMAM). Finally,
the prepared GQDs-PAMAM was functionalized with β-CD to obtain the glycodendrimer (GQDs-PAMAM-β-CD).
The synthesized glycodendrimer characterized using several techniques. The phenol-sulfuric acid test obtained
the amount of the β-CD about 30.37 %. 61.2 % of doxorubicin (DOX) was loaded in the prepared glycodendrimer.
DOX@GQDs-PAMAM-β-CD displayed the pH-sensitive drug release profile, which fitted the Higuchi
kinetic model. The biological test outcomes showed that the GQDs-PAMAM-β-CD is a safe carrier with good
capability in penetration to the cancer cells. Moreover, DOX@GQDs-PAMAM-β-CD exhibited more efficiency in
the killing of the cancer cells compared to neat DOX. Obtained results suggested that prepared glycodendrimer
could be a potential nanosystem for breast cancer treatment. |
