    A series of 4-aryl-4, 7-dihydrothieno [2, 3-b] pyridine-5-carboxylate derivatives (I) was synthesized and tested for binding affinity to Ca2+ channels in rat cerebral cortex membranes, coronary vasodilator effect in isolated guinea pig hearts, and antihypertensive activity in spontaneously hypertensive rats.Several compounds had potent coronary vasodilator and antihypertensive activities.The structure-ctivity relationships of the series indicated that a lipophilic 3-alkyl substituent with moderate bulkiness was effective for enhancing the pharmacological potencies.Among them, methyl 4, 7-dihydro-3-isobuty1-6-methy1-4-(3-nitrophenyl) thieno [2, 3-b] pyridine-5-carboxylate (S-312) was selected as a promising cardiovascular agent.The relationship between the absolute configuration of S-312 and its biological activities is also presented.
    合成了一系列4-芳基-4, 7-二氢噻吩[2, 3-b]吡啶-5-羧酸酯衍生物(I),并测试了它们对大鼠大脑皮层膜中Ca2+通道的结合亲和力、在离体豚鼠心脏中的冠状动脉扩张作用以及在自发性高血压大鼠中的抗高血压活性。若干化合物具有强大的冠状动脉扩张和抗高血压活性。该系列的结构-活性关系表明,具有适中体积的脂溶性3-烷基取代基对增强药理效能是有效的。其中,甲基4, 7-二氢-3-异丁基-6-甲基-4-(3-硝基苯基)噻吩[2, 3-b]吡啶-5-羧酸酯(S-312)被选为一个有前景的心血管药物。还介绍了S-312的绝对构型与其生物活性之间的关系。

    5-Dihydro-4-methyl-2-phenyl-1,5-benzothiazepine-3-carboxylic acid esters, based on the structures of dihydropyridines and diltiazem, were synthesized from o-aminothiophenol and 2-(phenylmethylene)- 3-oxobutanoic acid esters. Biological evaluation in the potassium-depolarized rabbit aorta suggests that these compounds are calcium channel blockers. The in vitro activity was further confirmed by electrophysiological
