thioredoxin-1 inhibitor PX-12 An orally bioavailable small molecule with potential antineoplastic activity. Thioredoxin-1 inhibitor PX-12 irreversibly binds to thioredoxin-1 (Trx-1) and inhibits its activity, which may result in growth inhibition and the induction of apoptosis. Overexpressed in many cancer cell types, the low molecular weight redox protein Trx-1 regulates transcription factor activity and inhibits apoptosis, promoting cell growth and survival; it also interacts with growth factors extracellularly to stimulate cell growth. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
