As TEI-9874, 2-(4-(6-cyclohexyloxy-2-naphtyloxy)phenylacetamide)ben zoic acid reduces allergen-specific immunoglobulin E (IgE) production by human peripheral blood mononuclear cells in vitro, we evaluated its potency on an allergen-induced asthmatic model in Brown-Norway rats. Inhaled ovalbumin induced the immediate-phase asthmatic response, the late-phase asthmatic response, the infiltration of leukocytes into bronchoalveolar lavage fluid, and an increase of serum anti-ovalbumin IgE. These parameters were suppressed by the treatment with TEI-9874 (3, 10, and 30 mg/kg p.o.). The ovalbumin-induced airway hyperresponsiveness was prevented by TEI-9874 (30 mg/kg p.o.). Furthermore, the suppression of the immediate-phase asthmatic response and the late-phase asthmatic response by TEI-9874 was almost completely extinguished by the exogenous administration of rat anti-ovalbumin antiserum. These results indicate that the efficacy of TEI-9874 on the asthmatic response is mainly mediated by the suppression of allergen-specific IgE production and TEI-9874 appears to be a good candidate as therapy for IgE-mediated allergic asthma.
