bis-(tetrahydropapaverine) ring systems have been synthesised in expectation of better antispasmodic activity in comparison with papaverine. The synthesis of the targeted heterocycles is described along with a discussion of their structure activity relationship. The general synthetic methods of bis-(tetrahydropapaverine) analogues involve tetrahydropapaverine, various piperazines, diisocyanates and diisothiocyanates
已经合成了一系列新的N-取代的双-(四氢罂粟碱)环系统,以期与罂粟碱相比具有更好的抗痉挛活性。描述了目标杂环的合成,并讨论了其结构活性关系。双-(四氢罂粟碱)类似物的一般合成方法包括四氢罂粟碱,各种哌嗪,二异氰酸酯和二异硫氰酸酯作为起始原料。药理学评估涉及使用连接至生理描记器的力位移传感器放大器对新鲜取出的豚鼠回肠进行体外解痉活性。在本研究合成的类似物中,N,N'-双-[2-氨基甲酰基-1-(3,4-二甲氧基苄基)-6,7-二甲氧基-1,2,3,4-四氢异喹啉基]哌嗪(22 ),
