Markers of oxidative-nitrosative stress induced by artesunate are followed by clastogenic and aneugenic effects and apoptosis in human lymphocytes.

Artesunate (ARS) is a semi-synthetic derivative of artemisinin, used as an outstanding antimalarial drug, which also displays antitumor, anti-inflammatory and immunosuppressive effects. In spite of the numerous reports showing the antitumor activity of ARS, the particular mechanisms associated with its cytotoxicity and genotoxicity in non-neoplastic human cells remain unclear. Here we aimed to verify the specific chromosome damages and the changes in markers of oxidative-nitrosative stress and apoptosis triggered by ARS exposure in human peripheral blood lymphocytes.
