Melanoma is one of the deadliest cancers with very low response and survival rates. Main reason of poor outcomes of therapy is the inherent resistance of melanoma cells. Survivin is a protein which is overexpressed by melanoma cells and is known to impart resistance to them against apoptosis which is supposed to be induced by chemotherapy. Eugenol has been reported to inhibit survivin in breast cancer cells. Thus, in order to fight resistant melanoma in a more efficient manner, we formulated hyaluronic acid (HA) coated liposomes loaded with eugenol along with dacrabazine which is the gold standard chemotherapeutic agent used for melanoma treatment. After synthesizing the liposomes using solvent injection method, QbD was applied to optimize and obtain a final formulation with desired quality attributes. The optimized formulation was then subjected to performance analysis in cell lines and animals. Coated-Dacarbazine Eugenol Liposomes were found to possess almost 9 folds more cytotoxicity than dacarbazine solution against melanoma cell lines (at dacarbazine concentration of 0.5 μg/ml). The number of late apoptotic cells was also found to be much higher in formulation treated cells in comparison to dacarbazine solution treated cells. Migration assay and proliferation study also indicated towards considerably greater inhibition of cell migration and proliferation by Coated-Dacarbazine Eugenol Liposomes, signifying its potential against metastasis. Results of pharmacodynamic study on melanoma bearing C57BL/6 mice revealed that our formulation could significantly delay the tumor growth in comparison to dacarbazine solution; and biodistribution study confirmed the long circulating nature of the formulation. Thus, the results of this study indicate towards better possibilities of melanoma treatment if the treatment is focused on specific resistance mechanism of this deadly cancer.
