Novel asymmetric thioethers of the formula ##STR1## in which the general symbols have the following meanings: a is an integer of from 1 to 7, R.sup.o represents hydrogen or C.sub.1-7 -alkanoyl, R.sup.1 represents C.sub.1-3 -alkyl which may be substituted at the terminal carbon atom by a free or acylated hydroxy group, by a halogen atom having an atomic number of at most 17, or by methoxy, or represents C.sub.1-3 -perfluoroalkyl, R.sup.2 represents an optionally unsaturated aliphatic radical having from 5 to 15 carbon atoms, A represents ethylene or alternatively, if R.sup.1 represents a halogenated radical and/or B represents phenylene or ethylene, a single bond or vinylene, B represents a single bond, ethynylene or phenylene, R.sup.3 represents hydroxy, C.sub.1-7 -alkoxy or an optionally substituted amino group, and --X-- represents a single bond, a methylene group of an optionally N-acylated primary aminomethylene group, and their salts are active as leucotriene antagonists since they eliminate the contractions of smooth muscles brought about by leucotrienes, and are therefore suitable for the treatment of allergic, especially asthmatic, conditions.
化合物的中文翻译如下:新颖的不对称硫醚化合物,化学式为##STR1##,其中一般符号的含义如下:a为1至7之间的整数,R.sup.o代表氢或C.sub.1-7-烷酰基,R.sup.1代表C.sub.1-3-烷基,可能在末端碳原子上被一个自由或酰化羟基、原子序数最多为17的卤素原子或甲氧基取代,或代表C.sub.1-3-全氟烷基,R.sup.2代表具有5至15个碳原子的可选不饱和脂肪基,A代表乙烯或者,如果R.sup.1代表卤代基或B代表苯基或乙烯基,单键或乙烯基,B代表单键、乙炔基或苯基,R.sup.3代表羟基、C.sub.1-7-烷氧基或可选择取代的氨基,--X--代表单键、一个可选N-酰化的一级氨基甲基或亚甲基,它们的盐具有白三烯拮抗剂的活性,因为它们消除了由白三烯引起的平滑肌收缩,并因此适用于治疗过敏性疾病,尤其是哮喘病。
