    摘要:
    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

    名称:
    Toward Tissue-Selective Pancreatic B-Cells KATP Channel Openers Belonging to 3-Alkylamino-7-halo-4H-1,2,4-benzothiadiazine 1,1-Dioxides
    摘要:
    3-(Alkylamino)-7-halo-4H-1,2,4-benzothiadiazine 1,1-dioxides were synthesized, and their activity on rat-insulin-secreting cells and rat aorta rings was compared to that of the K-ATP channel activators diazoxide and pinacidil. Structure-activity relationships indicated that an improved potency and selectivity for the pancreatic tissue was obtained by introducing a fluorine atom in the 7-position and a short linear (preferably ethyl) or cyclic (preferably cyclobutyl) hydrocarbon chain on the nitrogen atom in the 3-position. By contrast, strong myorelaxant activity was gained by the introduction of a halogen atom different from the fluorine atom in the 7-position and a bulky branched alkylamino chain in the 3-position. Thus, 3-(ethylamino)-7-fluoro-4H-1,2,4-benzothiadiazine 1,1-dioxide (11) expressed a marked inhibitory activity on pancreatic B-cells (IC50 = 1 muM) associated with a weak vasorelaxant effect (ED50 > 300 muM), whereas 7-chloro-3-(1,1-dimethylpropyl)amino-4H-1,2,4-benzothiadiazine 1,1-dioxide (27), which was only slightly active on insulin-secreting cells (IC50 > 10 muM), was found to be very potent on vascular smooth muscle cells (ED50 = 0.29 muM). Radioisotopic and electrophysiological. investigations performed with 7-chlorinated, 7-iodinated, and 7-fluorinated 3-alkylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides confirmed that the drugs activated K-ATP channels. The present data revealed that subtle structural modifications of 3-(alkylamino)-7-halo-4H-1,2,4-benzothiadiazine 1,1-dioxides can generate original compounds activating K-ATP channels and exhibiting different in vitro tissue selectivity profiles.
