Recently we presented a series of 6-ethyl and 6-benzylthieno[2,3-b][1,4]thiazine derivatives with relaxing effects on vascular smooth muscle and terminal ileum. In this report the synthesis of further thieno[2,3-b][1,4]thiazine derivatives and related compounds with a thieno[2,3-b][1,4]thiazepine or thieno[3,2-b][1,4]thiazine ring system is described. The pharmacological effect of the agents was tested in
最近,我们提出了一系列6-乙基和6-苄基噻吩并[2,3-b] [1,4]噻嗪衍生物,它们对血管平滑肌和末端回肠具有松弛作用。在该报告中,进一步合成了噻吩并[2,3-b] [1,4]噻嗪衍生物和相关化合物以及噻吩并[2,3-b] [1,4]噻氮平或噻吩并[3,2-b]描述了[1,4]噻嗪环系统。在豚鼠的分离的平滑肌(回肠末端,肺动脉,主动脉环,肌子宫条)和心脏(乳头肌,自发跳动右心房)肌肉制剂中测试了这些药物的药理作用。等轴测收缩,用高K +(含有60或90 mM KCl的营养液)或激动剂预收缩平滑肌制剂,同时电刺激乳头肌(1 Hz)。在V1A受体亚型所在的分离的乳头肌中测试了测试化合物对血管加压素的拮抗活性。取决于测试化合物的化学结构,对血管加压素的双相反应被拮抗。噻吩并[3,2-b] [1,4]噻嗪比噻吩并[2,3-b] [1,4]噻嗪和噻吩并[2,3-b] [1,4]噻嗪化合物更有效。
