L-Selenocystine

L-Selenocystine is a selenium-containing amino acid. L-Selenocystine has redox properties. L-Selenocystine is cytotoxic to various tumor cells and can induce the production of ROS and apoptosis. L-Selenocystine can block the Nrf2 and autophagy pathways. L-Selenocystine has anti-tumor activity[1][2][3][4].
