quinolyl nitrogen atom was not a determinant of activity, ii) increasing the size of the C-3 and C-S alkyl ester substituents decreases potency and iii) a C-4 1-oxido-4-pyridinyl substituent abolishes activity. The most active, and equipotent C-4 4-quinolinyl 6a and 8-quinolinyl 6b analogs, were approximately 8-fold less potent calcium channel antagonists than the reference drug nifedipine.
杂芳基羧酸醛3a-c与乙酰乙酸烷基酯4a-c和3-氨基巴豆酸烷基酯5a-b的汉茨缩合反应分别得到二烷基1,4-二氢-2,6-二甲基-4-(杂芳基)-吡啶-3,5。-具有C-4 4-喹啉基,8-喹啉基或1-氧代-4-吡啶基取代基的二羧酸酯6a-f获得的钙通道拮抗剂结构-活性关系表明,i)喹啉基氮原子的位置不是决定性的ii)增加C-3和CS烷基酯取代基的大小会降低效能,并且iii)C-4 1-氧化-4-吡啶基取代基会废除活性。最活跃,最均等的C-4 4-喹啉基6a和8-喹啉基6b 类似物的有效钙通道拮抗剂比参考药物硝苯地平低约8倍。
