Versions Notes

Nowadays, natural products are highly investigated in cancer research due to their wide distribution, numerous beneficial effects, and minimal side effects. Maslinic acid (MA) is found in different plant sources, but is mainly obtained from the olive tree [1]. This pentacyclic triterpene has an anti-tumor effect in various types of cancer, namely, colon cancer, gastric cancer, lung cancer, renal carcinoma, ovarian cancer, breast cancer, myeloma, pancreatic cancer, skin cancer, and leukemia, among others. It has reduced bioavailability due to its low solubility in aqueous solutions [2]; thus, to improve it, various formulations can be prepared. The purpose of the present study was to investigate the in vitro and in ovo effects of a maslinic acid nanoemulsion (MA-NE). The MA-NE was tested on two melanoma cell lines, A375 and SK-MEL-28, and on the chorioallantoic membrane, CAM. The sample produced a dose-dependent decrease in the human melanoma cell lines. In the tumor angiogenesis model, the formulation decreased cell migration. The results obtained indicate that MA-NE has an anti-melanoma effect and reduces tumor development within the tumor angiogenesis model. Further studies will be performed to elucidate the underlying mechanism of action.
