The synthesis of diversely substituted 3-isopropoxy-, 3-isopropylsulfanyl-, 3-isopropylsulfinyl-, and 3-isobutyl-4H-1,2,4-benzothiadiazine 1,1-dioxides is described. Their activity on pancreatic β-cells (inhibitory effect on the insulin releasing process) and on vascular and uterine smooth muscle tissues (myorelaxant effects) was compared to that of previously reported KATP channel openers belonging
描述了不同取代的3-异丙氧基-,3-异丙基硫烷基- ,3-异丙基亚磺酰基-和3-异丁基-4 H -1,2,4-苯并噻二嗪1,1-二氧化物的合成。将其对胰腺β细胞的活性(对胰岛素释放过程的抑制作用)以及对血管和子宫平滑肌组织的活性(对髓鞘松弛的作用)与先前报道的属于3-isopropylamino-4 H -1的K ATP通道开放剂进行了比较, 2,4-苯并噻二嗪1,1-二氧化物。本研究旨在评估O,S,S(= O)等位取代3-烷基氨基-4 H -1,2,4-苯并噻二嗪1,1-二氧化物的NH基团对生物活性的影响或CH 2团体。通过比较带有相同取代基的化合物,在胰腺β细胞上观察到的效价排名如下:3-异丙基氨基> 3-异丁基> 3-异丙氧基> 3-异丙基硫烷基> 3-异丙基亚磺酰基取代的4 H -1,2,4 -苯并噻二嗪1,1-二氧化物(NH> CH 2 > O> S> S(= O))。分子模型研
