structurally related to previously described potassium channel openers such as the benzothiadiazine dioxide BPDZ 73, were tested as putative K(ATP) channel activators on the pancreatic endocrine tissue and on the vascular smooth muscle tissue. The nature of the substituent introduced in the 7-position as well as the nature of the alkylamino side chain in the 3-position strongly affected both potency and tissue
本工作探讨了在7位上不同取代的3-烷基氨基-4H-1,2,4-苯并噻二嗪1,1-二氧化物。那些与先前描述的钾通道开放剂(例如二氧化苯并噻二嗪BPDZ 73)在结构上相关的化合物已在胰腺内分泌组织和血管平滑肌组织上作为推定的K(ATP)通道活化剂进行了测试。在7位引入的取代基的性质以及在3位引入的烷基氨基侧链的性质强烈影响4H-1,2,4-苯并噻二嗪1,1-二氧化物的效能和组织选择性。因此,在7位上带有甲基或甲氧基或在该位置上没有取代基并带有乙基,异丙基的化合物,发现3-位的环丁基或环丁基氨基是有效的和选择性的胰岛素从大鼠胰腺B细胞(即10a,10b,12b,12d,22c)释放的抑制剂。相反,3-烷基氨基-7-三氟甲基-(20a-c)和3-烷基氨基-7-戊基-4H-1,2,4-苯并噻二嗪1,1-二氧化物(11a,b)在表面上表现出明显的肌松活性。大鼠主动脉环。在后一种化合物中,3-烷基氨基
