Novel asymmetric thioethers of the formula ##STR1## in which the general symbols have the following meanings: R.sup.0 represents hydrogen or C.sub.1-7 -alkanoyl, R.sup.1 represents C.sub.1-3 -alkyl which may be substituted by one or more halogen atoms having an atomic number of at most 17, R.sup.2 represents an aliphatic radical having from 5 to 15 carbon atoms, A represents ethylene, a single bond or vinylene, B.sup.1 represents C.sub.1-7 -alkylene or phenylene, B.sup.2 represents a single bond, ethylene or phenylene, and M represents an aromatic radical of the partial formula ##STR2## in which the symbols have the following meanings: R.sup.3 represents hydrogen or C.sub.1-4 -alkyl, X represents NH, O, S or if R.sup.4 represents hydrogen, a single bond, one of the symbols R.sup.4 and R.sup.5 represents hydrogen and the other represents the group --CO--R.sup.6, or R.sup.4 and R.sup.5 together represent the radical --CO--C(R.sup.6).dbd.C(R.sup.7)--or--CO--C(R.sup.7).dbd.C(R.sup.6)--or R.sup.4 R.sup.5, together with X, represent the radical --N.dbd.C(R.sup.8)--C(R.sup.6).dbd.CH--, in which R.sup.6 represents --(CH.sub.2).sub.b --COOR.sup.3 (in which b=0 to 2) R.sup.7 represents hydrogen or C.sub.1-4 -alkyl and R.sup.8 represents hydrogen, methyl, mythoxy or halogen, 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.
新颖的非对称硫醚的化学式为##STR1##,其中一般符号的含义如下:R.sup.0代表氢或C.sub.1-7-烷酰基,R.sup.1代表C.sub.1-3-烷基,可以被一个或多个原子序数不超过17的卤素原子取代,R.sup.2代表具有5至15个碳原子的脂肪基,A代表乙烯基,一个单键或乙烯基,B.sup.1代表C.sub.1-7-烷基或苯基,B.sup.2代表一个单键,乙烯基或苯基,M代表部分化学式##STR2##中的芳香基,其中符号的含义如下:R.sup.3代表氢或C.sub.1-4-烷基,X代表NH,O,S或者如果R.sup.4代表氢,一个单键,R.sup.4和R.sup.5中的一个代表氢,另一个代表基团--CO--R.sup.6,或者R.sup.4和R.sup.5一起代表基团--CO--C(R.sup.6).dbd.C(R.sup.7)--或--CO--C(R.sup.7).dbd.C(R.sup.6)--或R.sup.4 R.sup.5,与X一起,代表基团--N.dbd.C(R.sup.8)--C(R.sup.6).dbd.CH--,其中R.sup.6代表--(CH.sub.2).sub.b--COOR.sup.3(其中b=0至2),R.sup.7代表氢或C.sub.1-4-烷基,R.sup.8代表氢,甲基,甲氧基或卤素,它们的盐作为白三烯拮抗剂活性,因为它们消除了由白三烯引起的平滑肌收缩,因此适用于治疗过敏,尤其是哮喘病情。
