In Vitro	Antileukinate inhibits the binding of human eotaxin to human eosinophils with an IC50 of 8.2 μM[2]. Antileukinate (10 μM, 100 μM) significantly suppresses eosinophil chemotaxis to human eotaxin[2].
In Vivo	Antileukinate (52.63 mg/kg; s.c.) protectes mice against acute pancreatitis and associated lung injury[1]. Antileukinate (5mg/kg; s.c.) inhibits the interaction between murine eotaxin and murine eosinophil[2]. Animal Model: Swiss mice(20-25g)[1] Dosage: 52.63 mg/kg Administration: Subcutaneous injection Result: Reduced pancreatic edema induced by Caerulein (50 μg/kg).
