Thioredoxin reductase peptide, corresponding to residues 53–67 in thioredoxin reductase (TrxR), is used in thioredoxin reductase research. Mammalian thioredoxin reductase (TR) catalyzes the reduction of the redox-active disulfide bond of thioredoxin (Trx) and is essential for cellular redox homeostasis.
Dvd-445 has good anti-cancer effect.Dvd-445 is an effective peptide covalent thioredoxin reductase 1 (TrxR1) inhibitor with IC50 value of 0.60 mol L M.
CAY10410 is an analog of prostaglandin D2/prostaglandin J2 (PGD2/PGJ2) with structural modifications intended to give it PPARγ ligand activity and resistance to metabolism. 15-deoxy-δ12,14-PGJ2 has been shown to be a potent ligand for PPARγ. Metabolism of the cyclopentenone prostaglandins PGA2, PGJ2, and δ12-PGJ2 occurs via glutathione addition across the α,β unsaturated enone. CAY10410 was designed as an analog of the PPARγ-binding prostaglandins which could not undergo this conjugation reaction. In human neuroblastoma SH-SY5Y cells, CAY10410 was not cytotoxic at up to 25 μM. It also failed to covalently modify thioredoxin or induce oxidative stress at 50 μM.
