Recent emphasis on the design of drug delivery systems typically involves effective transport a pharmaceutical substance to disease site with desired therapeutic efficacy and minimal cytotoxicity. Organelle-targeted peptides have become an integral part designing important class prodrug/prodrug assemblies for new supramolecular therapeutics owing their favorable biocompatibility, synthetic ease, tunability aggregation behavior, functionalization site-specificity. However, it is still limited due low selectivity. We designed folic acid-functionalized β-cyclodextrin (FA-CD) as platform specific selective organelle-targeted (such microtubule, lysosome, mitochondria) peptide chemotherapeutics folate receptor (FR) overexpressing cancer cell lines. Low toxicity was found FA-CD inclusion complex in FR-negative normal cells, but superior inhibition tumor growth no vivo xenograft model.
