3-benzothiazoles (series II) bearing an urea or a thiourea moiety at the 2-position were synthesized and tested as myorelaxants and inhibitors of insulin secretion. Several compounds (i.e. 13u and 13v) from series I showed a marked myorelaxant activity. Benzothiazoles bearing a strong electron withdrawing group (NO2, CN) at the 6-position and an alkyl group linked to the urea or the thiourea function at the
合成了一系列在2位带有尿素或硫脲部分的1,3,3-苯并噻唑(系列I)和4,5,6,7-四氢-1,3-苯并噻唑(系列II),并测试了其作为松驰剂和胰岛素分泌抑制剂。I系列的几种化合物(即13u和13v)显示出明显的肌肉松弛活性。发现在6位带有强吸电子基团(NO2,CN)和在2位与脲或硫脲官能团相连的烷基的苯并噻唑是最有效的化合物。系列II化合物的血管舒张活性较弱,这证明必须存在完整的芳香杂环系统。在存在10μM格列本脲的情况下,在预先收缩了80 mM KCl或30 mM KCl的主动脉环上测量时,某些活性化合物的髓鞘松弛活性降低,提示KATP通道参与了血管舒张作用。在大鼠胰岛上测试的系列I的某些化合物引起胰岛素分泌的显着抑制,其中13a对胰腺β细胞表现出明显的组织选择性。
