  Relaxant activity of 4-amido-3,4-dihydro-2H-1-benzopyran-3-ols and 4-amido-2H-1-benzopyrans on guinea pig isolated trachealis

  摘要：

  A series of 4-amido-3,4-dihydro-2H-1-benzopyran-3-ols and 4-amido-2H-1-benzopyrans related to the potassium channel activator cromakalim have been prepared and evaluated for their relaxant activity in guinea pig isolated tracheal spirals. Several analogues show enhanced relaxant activity relative to cromakalim in this preparation and the rank order of potency for those substituents investigated at C-6 was CF3 greater than CN greater than C2H5 greater than aza greater than or equal to CH3. One compound, trans-3,4-dihydro-2,2-dimethyl-4-(2-oxopiperidin-1-yl)-7-(trifluor omethyl)-2H- 1-benzopyran-3-ol (24), was resolved into its two enantiomers and the activity was shown to reside essentially in the (+)-isomer, adding further support to the suggestion that the smooth muscle receptor for these potassium channel activators is stereoselective.

  position. Exceptions to this were the 7-nitro-4-pyrrolidine analogue and the 6-nitro-3-chloropropylamine, which retained marked antihypertensive activity. All of these compounds were direct vasodilators and had comparable antihypertensive activity to hydralazine and to the calcium antagonist, nifedipine. The synthetic route to these compounds involves cyclization of of propargyl ethers to 2H-1-benzopyrans

  制备了一系列新型取代的反式-4-氨基-3,4-二氢-2,2-二甲基-2H-1-苯并吡喃-3-醇，并在有意识的乙酸脱氧皮质酮（DOCA）/盐水处理中测试了其降压活性。高血压大鼠。最佳的降血压活性需要一个强的吸电子基团与6位上的吡咯烷基或哌啶子基团一起进行6位取代。7-硝基-4-吡咯烷类似物和6-硝基-3-氯丙胺的例外，它们保留了明显的降压活性。所有这些化合物都是直接的血管扩张药，并且具有与肼屈嗪和钙拮抗剂硝苯地平相当的降压活性。这些化合物的合成路线包括将炔丙基醚环化为2H-1-苯并吡喃，然后通过溴代醇转化为3,4-环氧化物，用适当的胺开环。间取代的炔丙基醚在热环化反应中同时产生5-和7-取代的苯并吡喃，前者占优势。描述了一种新的制备2，2-二甲基-7-硝基苯并吡喃的途径。
