[Related Art] Recently, prostaglandins (PG's), thromboxanes (TX's), leukotrienes (LT's), and hydroxyeicosapentaenoic acid (HE) formed from arachidonic acid
TE's) and platelet-activating factor (PAF) have been elucidated to be deeply involved in the onset, progression and exacerbation of pathological conditions such as asthma as important chemical mediators in respiratory diseases (Junichi Nakano. Akimasa Miyamoto: Clinical Immunity
20, Suppl., P1-10, 1988). These chemical mediators are released from a group of cells, mainly leukocytes, by excessively responding to immune functions due to hypoxia / hypoxia, trauma, inflammation, and contact with pathogenic antigens (allergens). In fact, it has been reported that the content of chemical mediators in body fluids of asthmatics has been increased (MCLiu, ERBleecker, DP
roud, TLMcLemore, WCHubbard Prostaglandins, vol.3
5, p67-79, 1988). As an agent for suppressing the asthma-inducing action based on chemical mediators such as LT's, HETE's and PAF, imidazole compounds and the like have been known [JP-A-57-131769, JP-B-60-50190, JP-B-62). -2587 etc.], and those that suppress the asthma-inducing action caused by prostaglandin D 2 (PGD 2 ) are not known.
