  Compounds of the general Formula I: wherein Z is a bond, CR14=CR15 or CHR14-CHR15; X is O, S, SO, or S02 R1, R2, R3, R4, T, V are as defined in the prescription; and pharmaceutically acceptable salts thereof are inhibitors of leukotriene biosynthesis. These compounds inhibit the mammalian 5-lipoxygenase enzyme, thus preventing the metabolism of arachidonic acid to the leukotrienes. These compounds are thus useful in the treatment of asthma, allergic disorders, inflammation, skin diseases and certain cardiovascular disorders. The compounds are made into suitable pharmaceutical compositions for administration to patients. Certain of the compounds are novel.

  通式 I 的化合物：其中 Z 是键、CR14=CR15 或 CHR14-CHR15；X 是 O、S、SO 或 S02 R1、R2、R3、R4、T、V 如处方中所定义；及其药学上可接受的盐是白三烯生物合成的抑制剂。 这些化合物可抑制哺乳动物的 5-脂氧合酶，从而阻止花生四烯酸代谢为白三烯。 因此，这些化合物可用于治疗哮喘、过敏性疾病、炎症、皮肤病和某些心血管疾病。 这些化合物可制成适当的药物组合物给患者用药。 某些化合物是新型的。
