series of 4-(diarylmethyl)-1-[3-(aryloxy)propyl]piperidines and structurally related compounds were synthesized as calcium-channel blockers and antihypertensive agents. Compounds were evaluated for calcium-channel-blocking activity by determining their ability to antagonize calcium-induced contractions of isolated rabbit aortic strips. The most potent compounds were those with fluoro substituents in the
合成了一系列的4-(二芳基甲基)-1- [3-(芳氧基)丙基]哌啶和与结构相关的化合物,作为钙通道阻滞剂和降压药。通过确定化合物拮抗钙诱导的离体兔主动脉条收缩的能力,评估化合物的钙通道阻断活性。最有效的化合物是在二苯甲基的两个环的3-和/或4-位带有氟取代基的化合物。双(4-氟苯基)乙腈类似物79与双(4-氟苯基)甲基化合物1具有相似的效力。1(78)的亚甲基类似物和1的衍生物包含羟基(76),氨基甲酰基(80),氨基(81)或乙酰氨基(82)甲基上的取代基效力较低。在大多数情况下,苯氧基环上的取代基 芳氧基和哌啶氮之间距离的变化,以及用S,N(CH3)或CH2取代芳氧基的氧原子对效力的影响很小或中等。该系列中最好的化合物比维拉帕米,地尔硫卓,氟硝利嗪和利多巴嗪更有效,但比硝苯地平更弱。评价口服剂量为30 mg / kg的自发性高血压大鼠(SHR)的抗高血压活性。在测试的55种化合物中,只
