Abstract Dendrimers represents a highly branched three-dimensional structure that provides a high degree of surface functionality and versatility. PAMAM dendrimers are used as well-defined nanocontainers to conjugate, complex or encapsulate therapeutic drugs or imaging moieties. Star-burst [PAMAM] dendrimers represent a superior carrier platform for drug delivery. The present study was aimed at synthesis of a surface modified dendrimer for cancer targeted drug delivery system. For this 4.0 G PAMAM dendrimer was conjugated with Gallic acid [GA] and characterized through UV, IR, ¹H NMR and mass spectroscopy. Cytotoxicity study of dendrimer conjugate was carried out against MCF-7 cell line using MTT assay. The study revealed that the conjugate is active against MCF-7 cell line and might act synergistically with anti-cancer drug and gallic acid-dendrimer conjugate might be a promising nano-platform for cancer targeting and cancer diagnosis.
