Selective Inhibition of Extracellular Thioredoxin by Asymmetric Disulfides
摘要:
Whereas the role of mammalian thioredoxin (Trx) as an intracellular protein cofactor is widely appreciated, its function in the extracellular environment is not well-understood. Only few extracellular targets of Trx-mediated thiol disulfide exchange are known. For example, Trx activates extracellular transglutaminase 2 (TG2) via reduction of an intramolecular disulfide bond. Because hyperactive TG2 is thought to play a role in various diseases, understanding the biological role of utracellular Trx may provide critical insight into the pathogenesis of these disorders. Starting from a clinical-stage asymmetric disulfide lead, we have identified analogs with >100-fold specificity for Trx. Structure-activity relationship and computational docking model analyses have provided insights into the features important for enhancing potency and specificity. The most active compound identified had an IC50 below 0.1 mu M in cell culture and may be appropriate for in vivo use to interrogate the role of extracellular Trx in health and disease.
