An antiparasitic agent that forms stable complexes with copper and used for treatment of Alzheimer's disease. Displays anticancer properties by inhibition of proteasome activity. It targets tumor proteasome in vivo in a copper-dependent manner, resulting in formation of an active AR (androgen receptor) inhibitor and apoptosis inducer that is responsible for its observed antiprostate tumor effect. MW: 305.5. Purity ≥95% by HPLC
