Optically active 2-[4-(4-banzhydryl-1-piperazinyl)phenyl]ethyl methyl 1, 4-dihydro-2, 6-dimethyl-4-(3-nitrophenyl)-3, 5-pyridinedicarboxylate [(S)-(+)-1 and (R)-(-)-1] hydrochlorides were synthesized with high optical purities from (R)-(-)- and (S)-(+)-1, 4-dihydro-5-methoxycarbonyl-2, 6-dimethyl-4-(3-nitrophenyl)-3-pyridinecarboxylic acids [(R)-(-)-6 and (S)-(+)-6], which are availabel from (±)-6 by optical resolution using quinidine and cinchonidine, respectively. From pharmacological investigations of (S)-(+)-1 and (R)-(-)-1 such as the antihypertensive effect on spontaneously hypertensive rats and inhibition of [3H]nimodipine binding to rat cardiac mambrane homogenate, the active form of 1 was defined to be the (4S)-(+)-enantiomer of 1.
光学活性 2-[4-(4-苄基-1-哌嗪基)苯基]乙基甲基 1,4-二氢-2,6-二甲基-4-(3-硝基苯基)-3,5-吡啶二甲酸酯[(S)-(+)-1 和 (R)-(-)-1]盐酸盐由(R)-(-)-和(S)-(+)-1 以高光学纯度合成、4-二氢-5-甲氧基羰基-2, 6-二甲基-4-(3-硝基苯基)-3-吡啶甲酸[(R)-(-)-6 和 (S)-(+)-6]以高光学纯度合成。通过对(S)-(+)-1 和(R)-(-)-1 的药理研究,如对自发性高血压大鼠的降压作用和抑制[3H]尼莫地平与大鼠心肌膜匀浆的结合,1 的活性形式被定义为 1 的 (4S)-(+)- 对映异构体。
