This invention relates to novel benzopyran and other benzo-fused leukotriene B.sub.4 (LTB.sub.4) antagonists and the pharmaceutically acceptable salts thereof, to pharmaceutical compositions containing such compounds or a pharmaceutically acceptable salt thereof, and to methods of using such compounds as LTB.sub.4 antagonists. The compounds and the pharmaceutically acceptable salts of this invention inhibit the action of LTB.sub.4 and are therefore useful in the treatment of LTB.sub.4 induced illnesses such as inflammatory disorders including rheumatoid arthritis, osteoarthritis, inflammatory bowel disease, psoriasis and other skin disorders such as eczema, erythema, pruritus and acne, stroke and other forms of reperfuslon injury, graft rejection, autoimmune diseases, asthma, and other conditions where marked neutrophil infiltration occurs.
本发明涉及一种新型苯并吡喃和其他苯并螺合物的白三烯B.sub.4(LTB.sub.4)拮抗剂及其药学上可接受的盐,以及含有这些化合物或其药学上可接受的盐的制药组合物,以及将这些化合物用作LTB.sub.4拮抗剂的方法。这些化合物和本发明的药学上可接受的盐抑制LTB.sub.4的作用,因此在治疗LTB.sub.4诱导的疾病,如炎症性疾病,包括类风湿性关节炎,骨关节炎,炎症性肠病,牛皮癣和其他皮肤疾病,如湿疹,红斑,瘙痒和痤疮,中风和其他形式的再灌注损伤,移植排斥反应,自身免疫性疾病,哮喘以及其他出现明显嗜中性粒细胞浸润的情况下非常有用。
