Gemilukast

Research use only, not for human use.

Gemilukast (ONO-6950, ONO6950) is a potent, orally active, dual CysLT1 and CysLT2 antagonist with IC50 of 1.7 and 25 nM against human CysLT1 and human CysLT2, respectively.

Gemilukast (ONO-6950, ONO6950) is a potent, orally active, dual CysLT1 and CysLT2 antagonist with IC50 of 1.7 and 25 nM against human CysLT1 and human CysLT2, respectively; antagonized intracellular calcium signaling via human and guinea pig CysLT1 and CysLT2 receptors with IC50 values of 1.7 and 25 nM, respectively (human receptors) and 6.3 and 8.2 nM, respectively (guinea pig receptors); attenuated CysLT1-mediated bronchoconstriction and airway vascular hyperpermeability induced by LTD4 in normal guinea pigs (1 or 0.3 mg/kg, p.o.), strongly inhibited this asthmatic response to the level attained by combination therapy with montelukast and BayCysLT2RA.Asthma Phase 2 Discontinued.

Gemilukast is an orally active and potent dual cysteinyl leukotriene 1 and 2 receptors (CysLT1 and CysLT2) antagonist, with IC50s of 1.7, 25 nM for human CysLT1 and CysLT2, respectively. Both Gemilukast (ONO-6950) and montelukast inhibit human CysLT1 receptor-mediated calcium response with IC50 values of 1.7 and 0.46 nM, respectively.

Gemilukast at 0.03 to 10 mg/kg, p.o. dose-dependently attenuates LTC4-induced bronchoconstriction with almost complete inhibition at 3 mg/kg. The inhibitory effect of Gemilukast on LTC4-induced bronchoconstriction is significantly stronger than that of montelukast at the dose of 1 mg/kg or more. Gemilukast (0.03 to 1 mg/kg, p.o.) dose-dependently attenuates LTD4-induced airway vascular hyperpermeability with complete inhibition at 0.3 mg/kg. Gemilukast at 0.1 to 3 mg/kg, p.o. dose-dependently inhibits OVA-induced bronchoconstriction. The inhibitory effect of Gemilukast at 3 mg/kg is significantly greater than that of montelukast alone and comparable to that of combination therapy with montelukast and BayCysLT2RA.
