A fused thiophene compound of the formula: ##STR1## or a pharmaceutically acceptable acid addition salt thereof. In the above formula, one of E.sup.1, E.sup.2 and E.sup.3 is sulfur atom and other two of them are C--R.sup.1 and C--R.sup.2 respectively. R.sup.1 and R.sup.2 are the same or different and each is hydrogen, halogen, nitro, amino, cyano, hydroxyl, formyl, alkyl, alkoxy, haloalkyl, arylalkyl, acyl, alkoxyalkyl, acyloxyalkyl, hydroxyalkyl, acyloxyalkanoyl, alkoxyalkanoyl, hydroxyalkanoyl, aryloxyalkanoyl, haloalkanoyl, alkylthio, alkylsulfinyl, alkylsulfonyl, arylthio, arylsulfinyl, arylsulfonyl, hydroxysulfonyl, halosulfonyl, sulfamoyl, substituted sulfamoyl, carboxyl, acylamino, alkoxycharbonyl, carbamoyl, substituted carbamoyl or substituted amino. D is --CH.sub.2 -- or --S(O).sub.m -- (m is 0, 1 or 2). Q is straight or branched chain alkylene. T is primary amino, secondary amino or tertiary amino. A and B are the same or different and each is carbonyl or thiocarbonyl, or one of A and B is absent and the other of them is carbonyl or thiocarbonyl, or A is --CH.sub.2 -- and B is carbonyl or thiocarbonyl, and n is 1, 2 or 3 with the proviso that n is 2 or 3 when one of A and B is absent and the other of them is carbonyl or thiocarbonyl, and n is 1 or 2 when A and B are other combinations. In the above definitions, (hetero)aromatic ring and heterocyclic ring may optionally be substituted by 1 to 3 substituents. Said compounds have selective affinity for 5-HT.sub.1A receptor, or high affinity for 5-HT.sub.1A and dopamine D.sub.2 receptors so that they are useful as antianxietic drug, antipsychotic drug or drug for the disease of circulatory system. The intermediates for said fused thiophene compounds are also disclosed.
公式:##STR1## 的熔合噻吩化合物或其药学上可接受的酸加成盐。在上述公式中,E.sup.1、E.sup.2和E.sup.3中的一个是硫原子,另外两个分别是C--R.sup.1和C--R.sup.2。R.sup.1和R.sup.2相同或不同,每个都是氢、卤素、硝基、氨基、氰基、羟基、甲酰基、烷基、烷氧基、卤代烷基、芳基烷基、酰基、烷氧基烷基、酰氧基烷基、羟基烷基、酰氧基酰基、烷氧基酰基、羟基烷酰基、芳氧基烷酰基、卤代烷酰基、烷硫基、烷基磺酰基、芳基硫基、芳基磺酰基、羟基磺酰基、卤代磺酰基、磺酰胺基、取代磺酰胺基、羧基、酰氨基、烷氧羰基、氨基甲酰基、取代氨基甲酰基或取代氨基。D为--CH.sub.2--或--S(O).sub.m--(m为0、1或2)。Q为直链或支链烷基。T为一级氨基、二级氨基或三级氨基。A和B相同或不同,每个都是羰基或硫代羰基,或其中一个不存在,另一个是羰基或硫代羰基,或A为--CH.sub.2--,B为羰基或硫代羰基,n为1、2或3,但是当A和B是其他组合时,n为1或2,且上述定义中,(杂)芳环和杂环可以选择性地被1到3个取代基取代。所述化合物具有选择性亲和力5-HT.sub.1A受体,或高亲和力5-HT.sub.1A和多巴胺D.sub.2受体,因此它们可用于抗焦虑药、抗精神病药或循环系统疾病药物。还公开了所述熔合噻吩化合物的中间体。
