Background: Cancer is a challenge for either the patient or the healthcare manager. Treatment protocols based on chemotherapy or radiotherapy, or both are interfering with the patient’s life making him suffer rather than being alleviated. This burden pushed the scientists to search for new regimens that may help ameliorate patient as well as doctor inconvenience. Benefits of plant extracts as medical substitutes in cancer management have been proved. New nano formulated drug delivery systems may help overcoming remedy regimens barriers and obstacles. The present research topic aims to evaluate the anticancer power of two plant extracts in nano emulsion formulation on human melanoma cell line. Methods: Carvacrol and rosemary essential oils were obtained, and nano emulsions were formulated. NE were characterized using TEM for charge and size distribution. The A375 human melanoma cell line was cultured and propagated then IC50 of prepared NE was added. Assessment of cell cytotoxicity, effect on angiogenesis and apoptosis were tested. Results: After synthesis and characterization, both carvacrol nano emulsion (CNE) and rosemary nano emulsion (RNE) were capable of inhibiting melanoma cell line viability, angiogenesis and they enhanced the expression of caspase-3 proapoptotic marker. Conclusion: Rosemary and carvacrol extract nano emulsions could be a new revolutionary agent in human melanoma therapy and these formulations can be applied locally.
