Phenol derivatives of the formula ##STR1## wherein A and B have the same or different meanings and each represent one of the groups --C.tbd.C--, cis--CH.dbd.CH-- or trans--CH.dbd.CH--, R.sub.1 is hydrogen, an optionally substituted alkyl or phenyl group or a cycloalkyl group, R.sub.2 is hydrogen, methyl or ethyl, R.sub.3 represents hydrogen, acetyl or propionyl, R.sub.4 has the same meaning as R.sub.3 or represents an alkyl group, R.sub.5 is a carboxylic or a hydroxy group or a functional derivative of such groups or R.sub.5 is a nitrile group and R.sub.6 is hydrogen, an alkyl group or the group OR.sub.4 which specifically inhibit 5-lipoxygenase and are useful in pharmaceutical compositions for prophylaxis and treatment of diseases due to the action of leukotrienes. The compounds are prepared by reacting suitable acetylene compounds or metal derivatives thereof with alkyl or aryl halides or by means of Wittig reactions optionally followed by transforming the member R.sub.5 into another carboxylic acid derivative. By hydrogenation A and B may be varied within the scope of the definition.
公式为##STR1##的酚衍生物,其中A和B具有相同或不同的含义,每个代表--C.tbd.C--、顺式--CH.dbd.CH--或反式--CH.dbd.CH--中的一个基团,R.sub.1为氢、可选择取代的烷基或苯基或环烷基,R.sub.2为氢、甲基或乙基,R.sub.3代表氢、乙酰基或丙酰基,R.sub.4具有与R.sub.3相同的含义或代表烷基基团,R.sub.5为羧基或羟基或这些基团的功能衍生物,或R.sub.5为腈基,R.sub.6为氢、烷基或OR.sub.4基团,这些化合物特异性地抑制5-脂氧酶,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。这些化合物是通过将适当的乙炔化合物或其金属衍生物与烷基或芳基卤化物反应,或通过维特格反应,随后将成员R.sub.5转化为另一个羧酸衍生物而制备的。通过氢化,A和B可以在定义的范围内变化。
