Pleiotropic anti-cancer activities of novel non-covalent thioredoxin reductase inhibitors against triple negative breast cancer.

ABSTRACT: Mounting evidence shows that tumor growth and progression rely on thioredoxin reductase 1 (TXNRD1)-mediated detoxification of oxidative stress that results from deregulated metabolism and mitogenic signaling in tumors. TXNRD1 levels are significant higher in triple negative breast cancer (TNBC) compared to normal tissue, making TXNRD1 a compelling TNBC therapeutic target. Despite the many attempts to generate TXNRD1 inhibitors, all known and reported compounds inhibiting TXNRD1 are problematic; they interact with TXNRD1 irreversibly and non-specifically resulting in numerous adverse side effects. Recently, a series of breakthrough studies identified a novel regulatory site, the 'doorstop pocket', in Schistosoma mansoni thioredoxin glutathione reductase, a TXNRD-like enzyme and an establish
