Cytotoxic effect of Mercurialis annua L. methanolic extract on six human solid cancer cell lines

The unprecedented rates of resistance of cancer cells to traditional chemotherapeutic medications necessitated relentless exploration and drug design in an attempt to introduce safe and effective new antineoplastic agents. The latter is a particular pivotal to the treatment of solid tumors malignancies which represent the top causes of cancer deaths. Our laboratory has established a line of research to investigate...
