二氢吡啶类钙拮抗剂化合物及其制备方法与医药用途
技术领域
本发明涉及二氢吡啶类钙拮抗剂化合物,并提供了它们的制备方法及其在治疗心血管疾病方面的应用。
背景技术
钙拮抗剂,又称钙通道阻滞剂,能抑制跨膜钙内流及细胞内的钙释放,降低细胞内游离钙浓度及其利用率,抑制ATP酶的活性,降低心肌收缩力;使平滑肌细胞松弛,血管扩张,降低外周血管阻力。临床上钙拮抗剂主要用于治疗高血压、心绞痛、心律失常、充血性心肌病及缺血性心脏病等,是一类应用广泛的心血管药物。随着越来越多的新药上市,其中尤以二氢吡啶类引人注目,不但降压疗效确切,而且副作用小,价格便宜,已经成为临床一线药物。
作为第一个上市的二氢吡啶类钙拮抗剂硝苯地平(1),其侧链酯基结构呈电中性,因而水溶性差、吸收不好;尼卡地平(2)酯基上引入了水溶性好的氨基侧链,有了较好的吸收效果,但因为肝脏的首过效应或在体内代谢太快而不具有长效钙拮抗作用。我们在寻找新的二氢吡啶类药物时,设想用一个芳香支链取代的哌嗪基代替尼卡地平类药物结构中酯基侧链的氨基结构,通过芳香支链的脂溶性和大的取代基团空间位阻,影响药物与受体的结合,从而改变药物的药代学性质,延迟代谢。根据这一设想,合成了一系列哌嗪基烷基酯的二氢吡啶类化合物。

本发明共合成了21个新的二氢吡啶类化合物,现选择其中11个化合物进行药理活性筛选。实施方案可参见(周新妹,姚泰,夏满莉等,槲皮素与芦丁对大鼠主动脉环的舒张作用及机制,浙江大学学报(医学版)2006,35(1),29-33)。

1.2主要仪器
BL-410生物机能实验系统和HW-400S恒温平滑肌槽均为成都泰盟科技有限公司生产。
1.3实验动物
雄性SD大鼠,240~260g,由江宁青龙山动物繁殖场提供。合格证号:SCXK(苏)2002-0018。
2.实验方法
2.1Krebs Henseleit(K-H)营养液配制
NaCl:118.3mmol/L,KCl:4.7mmol/L,CaCl2:2.5mmol/L,MgSO4·7H2O:1.2mmol/L,KH2PO4:1.2mmol/L,NaHCO3:25mmol/L,glucose:11.1mmol/L。
2.2胸主动脉环的制备及张力测定
雄性大鼠击头致昏,迅速取胸主动脉,置于通以95%O2+5%CO2混合气体的K-H液中,小心去除周围结缔组织后将血管剪成约3mm宽的血管环,避免过度牵拉,以防损伤内皮。将血管环悬挂于含30mlK-H液的浴槽内,持续通以95%O2+5%CO2的混合气体,保持温度(37±0.5℃),将静息张力调至2.0g。平衡2h,期间每15min换液1次。
检验血管内皮活性:待动脉环稳定后,换液1次,浴槽中加入1μmol/L的NA,收缩达峰值15min后,加入1μmol/L的Ach,若加Ach后使NA预收缩的血管舒张大于60%,则认为内皮完整。反之,则认为内皮被破坏。
选择内皮完整的胸主动脉环进行实验,换液稳定后,加80mmol/L KCl诱发最大收缩幅度后依次累计给药使药物浓度分别达到0.05μmol/L,0.1μmol/L,0.5μmol/L,1μmol/L,2μmol/L,4μmol/L,10μmol/L,记录张力变化。对血管舒张程度以抑制率表示,即KCl诱发收缩最大张力与加入不同浓度药物后的血管张力之间的差值,该差值与KCl诱发最大收缩幅度的比值反映血管舒张程度。各药物组的动脉环标本数为6例,即实验重复6次。
3.实验结果:
如表1所示,化合物I4、I5、I6、I14、II2对KCl所致的完整内皮血管环收缩有抑制作用,其IC50分别为2.0、0.5、1.9、0.2、0.8μmol/L,均小于对照品苯磺酸左旋氨氯地平的IC50值4.1μmol/L,可见I4、I5、I6、I14、II2的活性均强于对照品苯磺酸左旋氨氯地平,其中I5和I14活性最强;而化合物I7、I11、I12、I13、II1、II3对KCl所致的完整内皮血管环收缩无明显影响。
