Description of ABR-238901

ABR-238901 is a newly developed blocker for S100A8/A9, which effectively inhibits the interaction between S100A8/A9 and the receptor for advanced glycation endproducts (RAGE) as well as toll-like receptor 4 (TLR4) [1-2].

ABR-238901(30 mg/kg;i.p) ameliorates septic cardiomyopathy in mice [3]. ABR-238901, administered at a dose of 10 mg/kg intraperitoneally, reduces neutrophil extracellular trap (NET) formation in abdominal sepsis by inhibiting S100A9[4]. In abdominal sepsis, ABR-238901 at doses of 30 mg/kg administered intraperitoneally reduced lung levels of MPO (a marker of neutrophil activation) by 74% [5]. In mice with multiple myeloma (MM), treatment with ABR-238901 at a dose of 30 mg/kg given orally daily for 5 days reduces angiogenesis in vivo[6]. Administering ABR-238901 at a dose of 30 mg/kg intraperitoneally for a short duration shifts the balance between inflammation and repair towards a reparatory environment in the ischemic myocardium [7].
