A series of dihydropyridines substituted at the 2-position by basic side chains are described and their potencies as calcium antagonists listed. One compound, 2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-3-ethoxycarbonyl-5- methoxycarbonyl-6-methyl-1,4-dihydropyridine (17, amlodipine) was found to be comparable in potency to nifedipine and to have an elimination half-life of 30 h in dogs. Oral bioavailability
描述了一系列在2-位被碱性侧链取代的二氢吡啶,并列出了其作为钙拮抗剂的效力。发现一种化合物2-[((2-氨基乙氧基)甲基] -4-(2-氯苯基)-3-乙氧基羰基-5-甲氧基羰基-6-甲基-1,4-二氢吡啶(17,氨氯地平)具有可比性。对硝苯地平有效,并具有30 h的消除半衰期。口服生物利用度接近100%,血液动力学反应起效缓慢,效果持久。已经制备了两种对映异构体,并且发现大部分活性与(-)异构体18有关。对17的相似类似物进行的X射线晶体学研究表明,两者之间存在弱氢键侧链氧和质子在环氮上。
