with a decrease of the angle between the planes of the two phenyl rings. AM1 net charge calculations showed that a neutral or positive charge distribution in the bridge portion was necessary for activity. 11-[[4-[4-(4-Fluorophenyl)-1- piperazinyl]butyryl]amino]-6,11-dihydrodibenzo[b,e]thiepin maleate (16, AJ-2615) showed a more gradual and longer lasting antihypertensive effect than diltiazem and nifedipine
合成了一系列[(ε-氨基链烷酰基)氨基] -6,11-二氢二苯并[b,e]噻吩和-5H-二苯并[a,d]环庚烯及相关化合物,并通过钙诱导的收缩来评估其钙拮抗活性。钾去极化的大鼠主动脉。二苯并三环体系的半经验分子轨道计算表明,钙拮抗活性随两个苯环平面之间的夹角的减小而增加。AM1净电荷计算表明,电桥部分的中性或正电荷分布对于活动是必要的。11-[[[4- [4-(4-氟苯基)-1-哌嗪基]丁酰基]氨基] -6,11-二氢二苯并[b,e]噻吩马来酸酯(16,AJ-2615)在口服自发性高血压大鼠(SHR)中显示出比地尔硫卓和硝苯地平更缓和,更持久的降压作用。化合物16在大鼠的乙酰甲胆碱诱导的ST升高和血管加压素诱导的ST抑郁试验中也具有抗心绞痛作用。16至5H-二苯并[a,d]环庚烯(19,5-[[4- [4-(4-氟苯基)-1-哌嗪基]-丁酰基]氨基] -5H-二苯并[ a,d]环庚烯)对心
