Aim: Garcinol (GAR)-loaded cationic nanoliposomes were developed to achieve potential antitumor efficacy on B16F10 melanoma cells in vitro and in vivo. Materials & methods: Two different phospholipids namely, distearoyl phosphatidylcholine (DSPC) and dipalmitoyl phosphatidylcholine (DPPC) were used in formulation to elucidate the difference in cellular uptake, cytotoxicity, in vivo tumor uptake (by scintigraphic imaging after technetium-99m radiolabeling) and therapeutic efficacy. Results: Different in vitro protocols, for example, MTT assay, apoptosis study, gene expression analysis, chromatin condensation and cytoskeleton breakdown analysis in B16F10 cell lines as well as scintigraphic analysis and tumor inhibition studies (B16F10 tumor xenograft model) revealed superiority of GAR-DPPC than GAR-DSPC and free GAR in melanoma prevention. Conclusion: Cationic nanoliposomal formulations could be a future medication for skin cancer treatment.
