Verwenden
PX 12 is an irreversible and competitive inhibitor of thioredoxin-1.
Definition
ChEBI: 2-(butan-2-yldisulfanyl)-1H-imidazole is a member of imidazoles.
Biologische Aktivität
px 12 is an inhibitor of thioredoxin-1 [1].thioredoxin-1 (trx-1) is a small redox protein with a conserved catalytic site and plays an important role in cells that includes the regulation of trans-activating activity and the dna binding of redox-sensitive transcription factors [1].in ht-29 human colon carcinoma cells and mcf-7 human breast cancer, px 12 prevented the hypoxia-induced increase in hif-1 protein. also, px 12 decreased inducible nitric oxide synthase, hif-1-trans-activating activity and vegf formation [2].in immunodeficient mice bearing ht-29 human colon xenografts, px 12 decreased the average tumor blood vessel permeability by 63% within 2 hours and returned to pretreatment values after 48 hours. px 12 reduced tumor-derived vegf and tumor after 24 hours. also, trx-1 showed a rapid decrease within 2 hours and maintained for 24 hours [1]. in mice bearing mcf-7 tumor xenografts, px 12 reduced hif-1ɑ and vegf protein levels [2]. in cancer patients, px-12 treatment significantly reduced the levels of trx-1 and vegf in plasma [3].
Biochem/physiol Actions
PX-12 inhibits the thioredoxin redox system and HIF-1a activity. PX 12 inhibits hypoxia-induced HIF-1a transcriptional activity (IC50 11 nM) and proliferation of HT29 and MCF-7 tumor cells (IC50 1.9 and 0.9 uM, respectively).
