The invention relates to a heterocyclic derivative of the formula: ##STR1## where D is O, S or NH; E is CH or when D is O or S, E is N; Y is S, O, CH.sub.2, SO or a direct bond; m is 0 to 4 and n is 1 to 4, provided that when Y is S, O or SO m is 1 to 4, when Y is O or SO, n is 2 to 4; A is C.sub.(3-4) chain comprising at least one C and also optionally S, N, 2N or N and S, and also comprising C.dbd.O or C.dbd.S or where possible SO.sub.2, the chain optionally substituted by 1 or 2 C.sub.(1-6) alkyl, benzyl, naphthylmethyl, 2-phenethyl, 4-phenylbutyl, pyridylmethyl, thiazolylmethyl, thienylmethyl, benzyloxy, pyridylmethoxy or phenoxymethyl radicals each optionally substituted on the aromatic ring system by 1 to 3 halogen atoms or methyl, methoxy, trifluoromethyl, dimethylamino, phenyl or phenoxy radicals; and the salts thereof.
本发明涉及一种杂环衍生物,其化学式为:##STR1## 其中D为O、S或NH;E为CH或当D为O或S时,E为N;Y为S、O、CH.sub.2、SO或直接键;m为0至4,n为1至4,但当Y为S、O或SO时,m为1至4,当Y为O或SO时,n为2至4;A为至少含有一个C的C.sub.(3-4)链,也可选含有S、N、2N或N和S,并且还包括C.dbd.O或C.dbd.S或在可能的情况下SO.sub.2,该链可选地被1或2个C.sub.(1-6)烷基、苄基、萘基甲基、2-苯乙基、4-苯基丁基、吡啶基甲基、噻唑基甲基、噻吩基甲基、苄氧基、吡啶基甲氧基或苯氧基甲基基团取代,每个基团可选地在芳香环系统上被1至3个卤素原子或甲基、甲氧基、三氟甲基、二甲基氨基、苯基或苯氧基基团取代;以及其盐。
