Beschreibung

General description

A cell permeable, highly stable phosphinyl gold (I) acetylide complex that acts as a highly potent inhibitor of thioredoxin reductase (TrxR; EC₅₀ = 2.8 nM). Acts by blocking the redox-active selenenylsulfide motif of TrxR in an irreversible manner. Displays high selectivity over glutathione reductase (EC₅₀ >1000 nM). Selectively reduces the viability and proliferation of MCF-7 and HT-29 cancer cells (IC₅₀ = 30 and 100 nM, respectively) without affecting normal cells. Suppresses the growth of MCF-7 xenografts in BALB/c nude mice (5 mg/kg; i.v.,given on alternate days for 15 days).
