In order to develop the efficiency and the specificity of anticancer drug delivery, we have designed an innovative nanocarrier. The nanocarrier system comprises of a multifunctional graphene oxide nanoparticle-based drug delivery system (GO-CS-M-DOX) as a novel platform for intracellular drug delivery of doxorubicin (DOX). Firstly, graphene oxide (GO) was synthesized by hummer’s method whose surface was functionalized by chitosan (CS) in order to obtain a more precise drug delivery, the system was then decorated with mannose (M). Further conjugation of an anti-cancer drug doxorubicin to the nanocarrier system resulted in GO-CS-M-DOX drug delivery system. The resultant conjugate was characterized for its physio-chemical properties and its biocompatibility was evaluated via hemolysis assay. The drug entrapment efficiency is as high as 90% and in vitro release studies of DOX under pH 5.3 is significantly higher than that under pH 7.4. The anticancer activity of the synthesized drug delivery system was studied by 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay against MCF-7 cell line. These results stated that the pH dependent multifunctional doxorubicin- chitosan functionalized graphene oxide based nanocarrier system, could lead to a promising and potential platform for intracellular delivery and cytotoxicity activity for variety of anticancer drugs.

Different Characteristics

Antibody-drug conjugates (ADCs) are currently used for the targeted delivery of drugs to diseased cells, but intracellular drug delivery and therefore efficacy may be suboptimal because of the large size, slow internalization and ineffective intracellular trafficking of the antibody. Using a phage display method selecting internalizing phages only, we developed internalizing single domain antibodies (sdAbs) with high binding affinity to rat PDGFRβ, a receptor involved in different types of diseases. We demonstrate that these constructs have different characteristics with respect to internalization rates but all traffic to lysosomes. To compare their efficacy in targeted drug delivery, we conjugated the sdAbs to a cytotoxic drug. The conjugates showed improved cytotoxicity correlating to their internalization speed. The efficacy of the conjugates was inhibited in the presence of vacuolin-1, an inhibitor of lysosomal maturation, suggesting lysosomal trafficking is needed for efficient drug release. In conclusion, sdAb constructs with different internalization rates can be designed against the same target, and sdAbs with a high internalization rate induce more cell killing than sdAbs with a lower internalization rate in vitro. Even though the overall efficacy should also be tested in vivo, sdAbs are particularly interesting formats to be explored to obtain different internalization rates.
