SM-15178
SM-15178 is a potent, orally active and selective leukotriene B4 (LTB4) receptor antagonist with an IC50 of 0.30 μM. SM-15178 attenuates LTB4 (HY-107608)-induced neutrophil accumulation in mouse skin and bronchoconstriction in guinea pigs. SM-15178 emonstrates significant anti-inflammatory efficacy across multiple animal models of inflammation. SM-15178 can be used for the research of chronic inflammatory diseases such as inflammatory bowel disease, psoriasis, and asthma.

LTB4 0.30 μM (IC50) |
SM-15178 (30 min) inhibits LTB4 binding to human neutrophils in a dose-dependent manner (IC50 = 0.30 μM)[3].
SM-15178 (up to 30 μM; 15-90 min) inhibits LTB4-induced chemotaxis of mouse and rat neutrophils and guinea pig eosinophils (IC50 = 0.52-0.72 μM)[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
SM-15178 (5 mg/kg; i.v.; 2-30 min pre-LTB4, or 40 mg/kg; p.o.; 60 min pre-LTB4) potently inhibits LTB4-induced bronchoconstriction in guinea pigs[2].
SM-15178 (20-40 mg/kg; p.o.; single dose) suppresses LTB4-induced transient leukopenia in guinea pigs[3].
SM-15178 (5-100 mg/kg; p.o.; single dose) suppresses Arachidonic Acid-induced neutrophil infiltration in mice[3].
SM-15178 (10-100 mg/kg; p.o.; one day or 1 h before SRBC challenge) inhibits sheep red blood cells (SRBC)-induced paw edema in mice[3].
