PX 12 is a competitive, irreversible inhibitor of thioredoxin 1 (Trx1), acting by binding to Cys73 of this enzyme.{22315} As Trx1 is overexpressed in certain cancers, PX 12 is effective in suppressing the growth of cancer cells, with growth inhibition in a panel of 60 human tumors significantly correlated with expression of Trx1 mRNA.{22325,22314} Through its effects on Trx1, PX 12 reduces hypoxia-induced HIF-1? protein levels (IC50 = 7.2 ?M), as well as expression of VEGF (IC50 = 10.4 ?M) and iNOS (IC50 = 18.1 ?M), culminating in attenuation of the proliferation of MCF-7 cells (IC50 = 1.9 ?M) and HT-29 cells (IC50 = 2.9 ?M) as well as reduced microvessel density in MCF-7 tumor xenografts.{22317} PX 12 also blocks Trx-mediated activation of extracellular transglutaminase 2 (IC50 = ~3 ?M) and Trx-1-increased expression and translation of CYP1B1.{22313,22312}
