El Compuesto 67 administrado por vía intravenosa (IV) era eficaz frente al asma experimental como se observa mediante una atenuación de broncoconstricción e inflamación pulmonar inducidas por metacolina (MCh). La eficacia significativa del Compuesto 67 se observó con una sola dosis IV de 1 mg/kg a 24 h antes de MCh. El área bajo la curva (AUC) para la respuesta de Paum indicada como un porcentaje del control de vehículo (AUC = 100 %) era de un 78,7 ± 8,1 % (p = 0,0323). La infiltración de eosinófilos en el fluido de lavado broncoaveolar (BALF) se redujo en un 63 % (p < 0,0001).
