What is Tauromustine?

Plain description, key identifiers and synonyms

Tauromustine is a water-soluble taurine-based nitrosourea with potential antineoplastic activity. Tauromustine alkylates DNA and causes DNA cross links independent of cell cycle, thereby resulting in disruption of DNA function and induction of apoptosis.
