  名称：

  Synthesis and calcium channel antagonist activity of dialkyl 4-(dihydropyridinyl)-1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylates

  摘要：

  The sodium borohydride reduction of 3,5-disubstituted 1,4-dihydro-2,6-dimethyl-4-(pyridinyl)pyridines 2 and 5 in the presence of methyl, phenyl, or tert-butyl chloroformate afforded the respective 4-(dihydropyridinyl)-1,4-dihydropyridines 4 and 6 in good yield. Products 4 comprised a mixture of the 1,2- and 1,6-dihydropyridinyl regioisomers 4a and 4b where 4a was always the predominant regioisomer. Compounds possessing a 4-[dihydro-1-(phenoxycarbonyl)-3-pyridinyl] substituent, such as 26, were also a mixture of two regioisomers 26a and 26b, and each regioisomer existed as a mixture of two rotamers in Me2SO-d6 at 25 degrees C (26a', 26a'', and 26b', 26b'') due to restricted rotation about the nitrogen-to-carbonyl carbamate bond. The calcium antagonist activities for 4 and 6 were determined by using the muscarinic receptor-mediated Ca2+-dependent contraction of guinea pig ileal longitudinal smooth muscle. The relative order of activities for the 4-(dihydropyridinyl) analogues was 4-(dihydro-3-pyridinyl) greater than 4-(dihydro-4-pyridinyl). Increasing the size of the C-3(5) alkyl ester substituents increased activity. Compounds having nonidentical ester substituents were more active than those having identical ester substituents. Replacement of the C-3 and/or C-5 ester substituents by a cyano substituent(s) decreased activity significantly. An approximate 1:1 correlation between the IC50 value for inhibition of [3H]nitrendipine binding and inhibition of the tonic component of the muscarinic-induced contractile response was observed. The test results suggest that a 4-(dihydropyridinyl) substituent is bioisosteric with a 4-(nitrophenyl) substituent on a 1,4-dihydropyridine ring where m- and p-nitrophenyl are bioisosteric with the 4-[1,2(1,6)-dihydro-3-pyridinyl] 4 and 4-(1,2-dihydro-4-pyridinyl) 6 isomers, respectively.

  摘要：

  乙酰乙酸烷基酯3与3-氨基巴豆酸甲酯（4）和吡啶甲醛5的汉茨缩合反应得到不对称的1,4-二氢-2,6-二甲基-4-（吡啶基）-3,5-吡啶二甲酸烷基甲基酯6，而缩合反应3与5和氢氧化铵反应得到对称的1,4-二氢-2,6-二甲基-4-（吡啶基）-3,5-吡啶二羧酸二烷基酯7。二取代的1,4-二氢-3的钙通道拮抗剂活性使用豚鼠回肠纵向平滑肌的毒蕈碱受体介导的Ca2 +依赖性收缩测定1,5-吡啶二甲酸6,7和9。异构吡啶基类似物6和7的相对效价顺序是2-吡啶基大于3-吡啶基大于4-吡啶基。增加烷基酯取代基的大小可增强活性。具有相同酯取代基的化合物比具有相同酯取代基的化合物更有效。用氰基取代基代替C-3和/或C-5酯取代基明显降低了活性。观察到抑制[3H]硝苯地平结合的IC50值与抑制毒蕈碱诱导的收缩反应的补品成分之间的近似1：1关系。测试结果表明4-（吡啶基）取代基在1,4-二氢吡啶环系统上具有
