the vascular smooth muscle tissue (relaxation of aorta rings). The biological activity of these new dimethylchroman derivatives was further compared to that of (+/-)-cromakalim, (+/-)-pinacidil, diazoxide and BPDZ 73. Structure-activity relationships indicated that an improved potency for the pancreatic tissue was obtained by introducing a meta- or a para-electron-withdrawing group such as a chlorine
本工作旨在探索一系列与(+/-)结构相关的R / S-3,4-二氢-2,2-二甲基-6-卤代4-(苯基氨基硫代羰基氨基)-2H-1-苯并吡喃-cromakalim,在4位和6位上有不同取代。这些推定的ATP敏感性钾通道激活剂(K(ATP))的生物学效应在体外在胰腺内分泌组织上(抑制胰岛素释放)和在血管平滑肌组织上(主动脉环松弛)进行了表征。进一步将这些新的二甲基苯并二氢吡喃衍生物的生物活性与(+/-)-cromakalim,(+/-)-吡那地尔,二氮嗪和BPDZ 73的生物活性进行了比较。构效关系表明,通过在C-4苯环上引入间位或对位电子吸收基团(例如氯原子),可以获得胰腺组织增强的效力,而与卤素原子的性质无关苯并吡喃核的6位。大多数原始的二甲基苯并二氢吡喃硫脲在抑制胰岛素释放方面比其“脲”同系物更有效,甚至比二氮嗪更有效。此外,与(+/-)-cromakalim或(+/-)-吡那地尔不同
