The present study described the synthesis of original R/S-6-alkylsulfonylamino-3,4-dihydro-2,2-dimethyl-2H-1-benzopyrans bearing a 3- or 4-substituted phenylthiourea or phenylurea moiety at the 4-position. Their biological effects were evaluated both on insulin-secreting and smooth muscle cells and were compared to those of reference KATP channel activators such as (±)-cromakalim, diazoxide and previously
本研究描述了原始的R / S -6-烷基磺酰基氨基-3,4-二氢-2,2-二甲基-2 H -1-苯并吡喃在4-上带有3-或4-取代的苯基硫脲或苯基脲部分的合成。位置。评估了它们对胰岛素分泌和平滑肌细胞的生物学作用,并将其与参考K ATP的生物学作用进行了比较。通道激活剂,例如(±)-cromakalim,重氮嗪和先前合成的cromakalim类似物。该研究旨在探索在2,2-二甲基苯并吡喃的6-位引入烷基磺酰基氨基取代基的影响,以改善二氢苯并吡喃衍生物的生物活性,组织选择性以及亲水性。发现几种化合物在抑制胰岛素释放过程方面比(±)-克罗卡林和二氮嗪等效或什至更有效。大多数新合成且亲水性更高的二氢苯并吡喃类药物也表现出显着的血管舒张活性,尽管它们的效力不及(±)-克罗卡林。其他药理和放射性同位素研究表明R / S - N-3-氯苯基-Nʹ-(3,4-二氢-6-甲基磺酰基氨基-2,2-二甲基-2
