A series of novel 6,7-disubstituted trans-3,4-dihydro-2, 2-dimethyl-4-pyrrolidino-(or piperidino)-2H-1-benzopyran-3-ols was prepared and tested for antihypertensive activity in the conscious spontaneously hypertensive rat (SHR) and compared with certain of their monosubstituted analogues. The potent blood pressure lowering activity of the 6-monosubstituted compounds was enhanced by incorporation of
制备了一系列新颖的6,7-二取代的反式3,4-二氢-2,2-二甲基-4-吡咯烷基-(或哌啶子基)-2H-1-苯并吡喃-3-醇,并在其中测试了降压活性有意识的自发性高血压大鼠(SHR),并与某些单取代类似物进行了比较。通过在C(7)处引入一个乙酰氨基或氨基,可以增强6个单取代化合物的有效降压活性,而在一个C(7)处引入一个氨基(而不是一个乙酰氨基),可以增强7-硝基取代的化合物的降血压活性。 C(6)。在反式-4-吡咯烷基-或-4-哌啶子基-2,2-二甲基-2H中6-硝基或6-氰基与7-(乙酰氨基)或7-氨基和6-氨基与7-硝基的组合-1-苯并吡喃酚在SHR中对肼屈嗪和钙拮抗剂硝苯地平具有优异的降压活性。这些化合物的合成途径涉及将2H-1-苯并吡喃转化为用吡咯烷或哌啶处理的溴代醇。当以6-氰基-7-[[(三氟乙酰基)氨基] -2,2-二甲基苯并吡喃]为起始原料时,完成了6-氰基-7-氨基类似物的制备。
