Substituted 3,4-dihydronaphthalenes of the formula I ##STR1## wherein R.sup.1 is a methyl or an amino group, R.sup.2 represents a hydrogen atom or a methyl group, and R.sup.3 is a linear or branched chain alkyl residue having 1 to 4 carbon atoms, an allyl or a crotyl group or a cyclopentyl group are disclosed which specifically inhibit 5-lipoxygenase and are useful in pharmaceutical compositions for prophylaxis and treatment of disorders attributable to the action of leucotrienes. The dihydronaphthalenes may be prepared by reacting a compound of formula II ##STR2## with hydroxylamine or a salt thereof to form the corresponding oxime, reducing the oxime to a hydroxylamine of formula III ##STR3## and introducing a --CO--R.sup.1 group.
公开了具有以下式I的3,4-二氢
萘烯的替代物##STR1##其中R.sup.1是甲基或
氨基,R.sup.2代表氢原子或甲基,R.sup.3是具有1至4个碳原子的直链或支链烷基残基,烯丙基或环戊基,这些化合物特异性地抑制5-脂氧合酶,并且在预防和治疗由
白三烯作用引起的疾病的药物组合物中有用。这些二氢
萘烯可以通过将具有式II的化合物##STR2##与
羟胺或其盐反应以形成相应的
肟,将
肟还原为具有式III的
羟胺##STR3##并引入一个--CO--R.sup.1基团来制备。
