A series of new nonpeptide vasopressin antagonists with a 6-ethyl-thieno[2,3-b][1,4]thiazine or 6-benzyl-thieno[2,3-b][1,4]thiazine skeleton and structural modifications of the aryl side chain were synthesized in this study. The effects on guinea pig heart and smooth muscle preparations were investigated. In the presence of AVP the compounds showed an antagonistic effect. The compounds did not change
一系列具有6-乙基-硫代[2,3-b] [1,4]噻嗪或6-苄基-硫代[2,3-b] [1,4]噻嗪骨架的一系列新型非肽加压素拮抗剂在这项研究中合成了芳基侧链。研究了对豚鼠心脏和平滑肌制剂的影响。在AVP存在下,化合物显示出拮抗作用。这些化合物不会改变右心房的自发率,并且在乳头肌中会产生轻微但不明显的负性肌力作用。对血管平滑肌和回肠末端的松弛作用更为明显。通常,对末端回肠的松弛作用更有效,这可能是由于V1a受体密度的差异所致。我们的结果证明,噻吩噻嗪环上第六位具有乙基的化合物(14、16,
