possible to conclude that the SARs for binding to the calcium channels in vascular and cardiac tissue are different. One of the compounds, 2-amino-1-[2-[[4-(2,3-dichlorophenyl)-3-(ethoxycarbonyl)-5- (methoxycarbonyl)-6-methyl-1,4-dihydropyrid-2-yl]methoxy]ethyl]-4( 3H)- imidazolone (20b, UK-55,444), was identified as a potent (IC50 = 8 x 10(-9) M) calcium antagonist which is 40-fold selective for vascular
描述了一系列在1位乙氧基甲基链的末端具有N-连接的杂环的1,4-二氢吡啶的合成。通过使用Langendorff灌注的豚鼠心脏模型确定,将这类DHP对大鼠主动脉的钙拮抗剂活性与其负性肌力活性进行比较。所检查的化合物对心脏组织的血管显示出广泛的选择性,在2-取代基末端具有酰胺基的那些类似物被证明具有最高的选择性。根据一系列1,2,3-三唑的体外数据,可以得出结论,与血管和心脏组织中钙通道结合的SAR不同。化合物之一是2-氨基-1- [2-[[4-(2,3-二氯苯基)-3-(乙氧羰基)-5-(甲氧羰基)-6-甲基-1
