A series of novel thiophene derivatives 3–17 were synthesized by initial reactions of 2-amino-4,5,6,7-tetrahydro-N-phenylbenzo[b]thiophene-3-carboxamide 1 and 2-amino-4,5,6,7-tetrahydro-benzo[b]thiophene-3-carbonitrile 7 with different organic reagents. The structures of newly synthesized compounds were confirmed by IR, 1H NMR, MS spectral data and elemental analysis. Initially the acute toxicity of
一系列新颖的噻吩衍生物的3 - 17由2-氨基-4,5,6,7-四氢-N-苯基苯并[b]噻吩-3-甲酰胺的初始反应合成1和2-氨基-4,5-, 6,7-四氢苯并[b]噻吩-3-腈7与不同的有机试剂。通过IR,1 H NMR,MS光谱数据和元素分析确认了新合成化合物的结构。最初,通过确定其LD 50来测定化合物的急性毒性。。筛选了所有化合物的抗心律失常,5-羟色胺拮抗剂和抗焦虑活性,与普鲁卡因酰胺,利多卡因,地西epa和丁螺环酮作为阳性对照相比,它们显示出高活性。报告了合成化合物的详细合成,光谱数据,LD 50和药理活性。
