SELENO-DL-CYSTINE Chemical Properties, Uses, Production
Uses
Selenocystine is a broad-spectrum anti-cancer agent. Selenocystine induces DNA damage in HepG2 cells, particularly in the form of DNA double strand breaks (DSBs). Selenocystine exhibits great promise as a therapeutic or adjuvant agent targeting DNA repair for cancer treatment[1].
Definition
ChEBI: Selenocystine is a diselenide and a selenoamino acid. It is functionally related to a selenocysteine.
