The invention relates to thiadiazole derivatives corresponding to the general formula ##STR1## in which Ar represents a nitrogen-containing aromatic heterocycle, in particular indolyl which is substituted or unsubstituted on the nitrogen atom with CO--(C.sub.1 -C.sub.4)alkyl; with (CH.sub.2).sub.n COR in which n represents 1 or 2 and R represents OR.sub.1 or NR.sub.1 R.sub.2 with R.sub.1 and R.sub.2, which may be identical or different, representing H or (C.sub.1 -C.sub.4)alkyl; with (C.sub.1 -C.sub.4) hydroxyalkyl; with (C.sub.2 -C.sub.6) alkoxyalkyl; tetrahydropyranyl; or with a --(CH.sub.2).sub.3 -- chain, the last carbon of which is attached to the phenyl ring of the indole to form a 6-membered ring; Z represents (a) the group ##STR2## where A and B, independently of each other, represent C, CH or N; and X.sub.1, X.sub.2, X.sub.3 and X.sub.4, which may be identical or different, represent H, (C.sub.1 -C.sub.3)alkyl, (C.sub.1 -C.sub.3)alkoxy, Cl, Br or trifluoromethyl, or alternatively (b) an optionally substituted naphthyl group, as well as their pharmaceutically acceptable salts.
该发明涉及与一般式##STR1##相应的噻二唑衍生物,其中Ar代表含氮芳香杂环,特别是在氮原子上用CO-(C.sub.1-C.sub.4)烷基取代或未取代的吲哚基; 用(CH.sub.2).sub.nCOR,其中n表示1或2,R表示OR.sub.1或NR.sub.1R.sub.2,其中R.sub.1和R.sub.2可以相同或不同,表示H或(C.sub.1-C.sub.4)烷基; 用(C.sub.1-C.sub.4)羟基烷基; 用(C.sub.2-C.sub.6)烷氧基烷基; 四氢吡喃基; 或用-(CH.sub.2).sub.3-链,其最后一个碳原子连接到吲哚的苯环上形成一个6元环; Z代表(a)基团##STR2##其中A和B分别独立地表示C,CH或N; X.sub.1,X.sub.2,X.sub.3和X.sub.4可以相同或不同,表示H,(C.sub.1-C.sub.3)烷基,(C.sub.1-C.sub.3)烷氧基,Cl,Br或三氟甲基,或者(b)一个可选取代的萘基团,以及它们的药学上可接受的盐。
