Description

Biochem/physiol Actions

AZD5904 (TX4) is an orally active 2-thioxanthine class suicide substrate that targets myeloperoxidase (MPO) for mechanism-based inactivation, covalently modifying MPO heme group without converting the enzyme to compound II. AZD5904 effectively inhibits peroxide-induced human MPO chlorination activity (IC50 = 0.2 μM) and extracellular MPO activity in PMA-stimulated human neutrophil cultures (by 68% at 1 μM). Oral administration (20-180 μmol/kg) of the racemate (TX3) is efficacious in reducing inflammation site MPO activity in mice in vivo with 10- to 19-fold selectivity over lactoperoxidase (LPO), thyroid peroxidase (TPO), and >70-fold selectivity over a panel of other enzymes, ion channels, and receptors.

Highly selective and orally available mechanism-based myeloperoxidase (MPO) inactivatior with in vitro and in vivo efficacy.
