AZM198
Based on 1 Customer Validation
AZM198 is an orally active myeloperoxidase (MPO) inhibitor. AZM198 irreversibly inactivates MPO (IC50=0.015 μM) via covalent binding to the heme prosthetic group, preferentially targets extracellular MPO activity, and reduces neutrophil extracellular trap formation, reactive oxygen species production and degranulation. AZM198 increases the fibrous cap thickness of atherosclerotic plaques, reduces lesion area, ameliorates hepatic steatosis and fibrosis in non-alcoholic steatohepatitis, and alleviates proteinuria and inflammatory infiltration associated with glomerulonephritis. AZM198 also decreases circulating levels of high-sensitivity Cardiac Troponin I and IL-1β, and mitigates endothelial cell injury. Therefore, AZM198 is suitable for research on various MPO-related diseases, including atherosclerotic cardiovascular disease, myocardial infarction, ischemic stroke, non-alcoholic steatohepatitis and crescentic glomerulonephritis.

Biological Activity
|
CYP3A4 19 μM (IC50) |
AZM198 (10 μM) reduces reactive oxygen species production, neutrophil degranulation and neutrophil extracellular trap formation in human neutrophils prestimulated with TNFα and activated by PR3-ANCA, and attenuates the activity of enzymatically active myeloperoxidase in human neutrophils stimulated with PMA[1].
AZM198 (10 μM; 18 h) attenuates human neutrophil-mediated endothelial cell injury in a co-culture system of TNFα-prestimulated, PR3-ANCA-activated neutrophils and endothelial cells incubated for 18 hours[1].
AZM198 (10 μM; 2 h) reduces neutrophil extracellular trap (NET) formation in human neutrophils isolated from healthy donors, which is induced by Phorbol 12-myristate 13-acetate (HY-18739)[2].

AZM198 (133 μmol/kg; p.o.; twice daily; for 48 h) does not significantly reduce early glomerular neutrophil accumulation in a mouse model of crescentic glomerulonephritis[1].
AZM198 (400 μmol/kg; p.o.; twice daily; for 7 consecutive days) does not enhance antigen-specific T cell responses in a mouse adoptive transfer model[1].
AZM198 (400 μmol/kg; administered via gavage; twice daily; for 7 consecutive days) exerts no protective effects on either histological or biochemical indicators of disease in this mouse model of anti-neutrophil cytoplasmic antibody-associated vasculitis[2].
AZM198 (500 μmol/kg; oral administration; continuous administration via diet formulation; 26 weeks) increases the survival rate of male SR-BIΔCT/ΔCT/Ldlr-/- mice fed a Western diet by 92% (to a 63% survival rate), reduces the incidence of major adverse cardiovascular events by 57%-75%, and also attenuates cardiac fibrosis, liver injury, and inflammatory activity in atherosclerotic lesions[3].
AZM198 inhibits MPO activity in vulnerable atherosclerotic plaques, increases fibrous cap thickness by 65%, reduces intraplaque fibrin and hemosiderin, and promotes a more stable plaque phenotype in Apoe-/- mice with plaque instability induced by tandem stenosis[4].
