The compounds of the present invention comprise substituted phenolic thioethers represented by the formula: ##STR1## wherein: R.sub.1 and R.sub.2 are the same or different and independently represent tert-alkyl or phenyl; A represents methylene or methylene substituted by alkyl, dialkyl or hydroxy, provided that when A includes hydroxymethylene, the hydroxymethylene group is not adjacent to a heteroatom; B represents sulfur, sulfoxide, sulfone, oxygen, --NH-- or nitrogen substituted by alkyl, phenyl, benzyl, substituted phenyl or substituted benzyl; C represents methylene or methylene substituted by alkyl; R.sub.3 represents CO.sub.2 H, CO.sub.2 -alkyl or a tetrazole group; m is 0 or 1, n is 2, 3 or 4 and p is 1, 2 or 3; amd the pharmaceutically acceptable salts thereof. The compounds of the present invention are specific inhibitors of 5-lipoxygenase and, therefore, are useful in the treatment of local and systemic inflammation, allergy and hypersensitivity reactions and other disorders in which agents formed in the 5-lipoxygenase metabolic pathway are involved.
本发明的化合物包括由以下式表示的取代酚硫醚:##STR1##其中:R.sub.1和R.sub.2相同或不同且独立地表示叔烷基或苯基;A表示亚甲基或被烷基、二烷基或羟基取代的亚甲基,但当A包括羟甲基时,羟甲基基团不与杂原子相邻;B表示硫、亚硫氧、砜、氧、--NH--或被烷基、苯基、苄基、取代苯基或取代苄基取代的氮;C表示亚甲基或被烷基取代的亚甲基;R.sub.3表示CO.sub.2 H、CO.sub.2 -烷基或四唑基团;m为0或1,n为2、3或4,p为1、2或3;以及其药学上可接受的盐。本发明的化合物是5-脂氧合酶的特异性抑制剂,因此在治疗局部和全身炎症、过敏和过敏反应以及其他涉及5-脂氧合酶代谢途径中形成的药物的紊乱方面具有用处。
