Abstract
本发明提供了通式I所表示的化合物、其衍生物、其异构体、消旋体或光学异构体、药用盐或其溶剂化物,含它们的药物组合物、其制备方法,以及所述的化合物在制备用于预防或治疗与血管内皮细胞功能紊乱相关的心血管疾病如高血压、充血性心衰、静脉内膜炎、微循环障碍等,以及糖尿病、衰老、缺血等疾病的药物中的应用,或作为工具药用于研究与血管内皮细胞功能或其功能紊乱相关的疾病的应用。
Description
本发明涉及具有调节血管内皮细胞功能活性的的取代的α-胺基腈、α-胺基羧酸、和α-胺基膦酸、其衍生物、其立体异构体、其药用盐、其溶剂化物,其制备方法,及其在预防或治疗血管内皮细胞功能紊乱相关的心血管疾病如高血压、充血性心衰、静脉内膜炎、微循环障碍等,以及糖尿病、衰老和缺血等疾病中的应用,或作为工具药用于研究血管内皮细胞功能或其功能紊乱相关的心血管疾病的用途,以及含有这些化合物的药物组合物。
心血管病是严重危害人类健康的重大疾病,是全世界人口死亡和致残的一个重要原因。血管内皮细胞是体内最大的、具有分泌作用的器官之一。它能分泌和代谢多种血管活性物质,在调节血管张力、维持血液平衡等方面具有不可替代的作用。血管内皮细胞上存在可被乙酰胆碱(acetyl choline,ACh)激活的蛋白(endothelial proteinactivated-by acetyl choline,EPA)。以EPA介导的内皮依赖的血管舒张反应性降低为特征的血管内皮细胞功能紊乱现象存在于高血压、冠心病、充血性心衰、衰老、缺血及慢性吸烟等疾病状态中。开发血管内皮细胞的保护药物,以维持其正常的生理功能和纠正异常的病理变化,将为上述心脑血管疾病提供新的防治措施。
EPA作为一个新的潜在的药物作用靶标,其生理作用可能是在内源性、内皮细胞自分泌的ACh作用下,调整血液张力,维持血液平衡。在以内皮细胞功能紊乱为起因的疾病中,EPA是最早期改变的指标,具有重要的病理生理作用。
已有的有关EPA的报道多作为毒蕈碱(M)受体的新亚型来研究,研究用的工具药也多局限于经典的M受体激动剂与拮抗剂。EPA作为一个新的潜在的药物作用靶标,在药物化学上尚未见有研究报道。
目前尚未见有特异性作用于血管内皮细胞的药物报道,但有报道一些他汀类、贝特类等降血脂药物与格列酮类降血糖药物具有调节内皮细胞功能的作用。
本发明的通式I化合物及其衍生物在调节内皮细胞功能、预防或治疗高血压、充血性心力衰竭等心血管疾病等方面的用途尚未见报道。
本发明的目的在于寻找并开发新的具有调节内皮细胞功能作用,可预防或治疗与血管内皮细胞功能紊乱相关的心血管疾病的药物,尤其是预防或治疗如高血压、充血性心衰、静脉内膜炎、微循环障碍等心血管疾病,以及糖尿病、衰老与缺血等的药物。
本发明人经广泛深入研究,现已发现具有优良的调节血管内皮细胞功能作用的式I或式Ia所示的化合物,该类化合物可用于预防或治疗与血管内皮细胞功能紊乱相关的心血管疾病如高血压、充血性心力衰竭、静脉内膜炎、微循环障碍等,以及糖尿病、衰老、缺血等疾病。研究表明,式I或式Ia所示的化合物具有调节血管内皮细胞功能的作用。进一步的合成与研究表明,本发明所包括的衍生物与适当的无机酸或有机酸或与无机碱或有机碱形成的药用盐也同样具有调节血管内皮细胞功能的作用。本发明基于上述发现得以完成。
本发明第一方面涉及通式I所示的化合物、其衍生物、其异构体、消旋体或光学异构体、其药用盐、或溶剂化物在制备可用于预防或治疗与血管内皮细胞功能紊乱相关的心血管疾病如高血压、充血性心力衰竭、静脉内膜炎、微循环障碍等,以及糖尿病、衰老、缺血等疾病的药物中用途或作为用于研究血管内皮细胞功能或血管内皮细胞功能紊乱相关的心脑血管疾病的工具药的用途,

下面的生物活性实验用来进一步说明本发明。
生物效应实验1本发明式I代表性化合物对离体大鼠主动脉环内皮依赖的血管舒张反应性的影响(EPA激动活性)及对豚鼠回肠收缩反应的影响(M3激动活性)
表1 本发明式I代表性化合物的EPA激动活性与M3激动活性
*注:“-”代表明显活性,“+”代表最大舒张率<20%,“++”代表最大舒张率为20-50%,“+++”代表最大舒张率>50%.
表2 本发明式I代表性化合物对离体大鼠主动脉环血管舒张反应性影响的内皮依赖性
注:X±SD,n=3-14,*P<0.05,**P<0.01.
以上实验结果表明,本发明式I化合物能选择性在激活EPA,而对M3受体没有明显作用;其舒血管效应是内皮依赖的。
生物效应实验1的研究方法之一,Wistar大鼠,♀♂兼用,体重200-250g;豚鼠,♀♂兼用,体重300±50g,均由军事医学科学院实验动物中心提供。Wistar大鼠断头处死,迅速开胸,取出主动脉胸腹段,置于盛有Krebs-Ringer营养液(NaCl 118、KCl 4.7、CaCl2 11.0、KH2PO4 1.2、NaHCO3 25.0、葡萄糖11.1、EDTACa-Na2 0.026mmol.L-1,PH7.4)的培养皿中,切成3-5mm固定长度的动脉环,置于盛有10mlKrebs-Ringer营养液的37℃恒温浴槽内,下端固定,上端通过张力换能器连于自动平衡记录仪,记录血管环的张力变化,持续通入95%O2和5%CO2的混合气。动脉环前负荷为1.5g,平衡60min后,进行下述实验,以0.62μmol.L-1NE预收缩血管,再平衡40min后,以0.62μmol.L-1NE收缩血管,达最大收缩幅度并至坪值,稳定后加入10-5mol.L-1被评筛化合物,观察新结构化合物对血管张力的影响。以NE诱发的最大收缩幅度为100%,化合物诱发血管舒张或收缩的幅度与NE诱发最大收缩幅度之间的比率为血管的舒张率或收缩率。
用棉棒轻轻擦去内皮后,在0.62μmol.L-1NE收缩血管,达最大收缩幅度后,加入10-6mol.L-1ACh,观察有无舒血管反应,以初步判断内皮是否去干净,冲洗标本并平衡40min后,0.62μmol.L-1NE收缩血管,达最大收缩幅度后,加入10-5mol.L1被评筛化合物,观察血管张力的变化,初步判断其舒血管作用是否为内皮依赖性舒张作用。
实验方法详见参考文献:Feletou M,Vanhoutte PM.Endothelium-dependent hyperpolarization of canine coronarysmooth muscle.Br J Pharmacol,1988;93:515-524.
生物效应实验1的研究方法之二,豚鼠实验前禁食24小时,击头致昏后,迅速取出距盲肠10-20cm的这断回肠,截成1.5cm的肠管,以台氏液冲洗干净后,置于混合O2饱和的台氏液中备用。上述肠管的两端以丝线结扎,置于盛有10ml台氏液的37℃恒温浴槽内,持续通入95%O2和5%CO2的混合气。下端固定,上端通过张力换能器连于自动平衡记录仪。静息张力为3.0g,标本稳定20min后,基线稳定后开始实验,描记回肠收缩曲线。以10-6mol.L-1槟榔碱为阳性对照,槟榔碱能引起快速且很强的收缩反应,持续30min以上。受试化合物浓度为10-5mol.L-1,实验数据以回肠的收缩率表示。实验方法详见参考文献:Bekemeier H,Hirschelmann R,Giessler AJ.Carrageenin-inducedthrombosis in rats and mice:A model for testing antithromboticsubstance?Agents and Actions,1985;16(5):446-451.
生物效应实验2 在离体大鼠主动脉环上活性候选化合物对一氧化氮和前列环素生成的影响。
表3 吲哚美辛与L-NAME对化合物1与化合物2的舒血管效应的拮抗作用
注:X±SD,n=3-14,*P<0.05,**P<0.01。实验数据采用X±SD表示,采用成组t检验或自身配对t检验进行显著性分析,应用SAS D2P8程序.
以上实验结果表明,化合物1和化合物2的舒血管效应能被L-NAME和吲哚美辛所拮抗,而L-NAME为NO合成酶抑制剂,特异性地抑制血管内皮细胞合成并释放NO,拮抗其舒血管效应;吲哚美辛为花生四烯酸代谢过程中的环氧合酶抑制剂,能够特异性地抑制PGI2的生成,拮抗其舒血管效应;
综合上述结果,化合物1和2诱发的内皮依赖性舒血管反应是通过PGI2和NO两个途径共同起作用,
生物效应2的实验方法采用离体大鼠主动脉环实验,以0.62μmol.L-1NE收缩标本,达最大收缩平衡后,加入10-5mol.L-1吲哚美辛和10-4mol.L-1L-NAME预孵育标本5min后,加入0.62μmol.L-1NE收缩标本,达最大收缩平衡后,加入10-5mol.L-1化合物1和2,观察标本舒张率的改变。
生物效应实验3 新化合物1对大鼠血压和心功能的影响
表4 化合物1(10mg/kg,iv)对麻醉正常大鼠血压和心功能的影响
注:MAP为平均动脉压;HR为心率;心脏收缩功能指标有:LVSP为左室收缩压,+dp/dtmax为左室等容期压力最大变化速率,+dp/dtmax/IP为左室压力对数值,T+dp/dtmax为室内压上高段最大变化速率所在时间,Vmax为心肌纤维缩短速率;心脏舒张功能指标有:-dp/dtmax为左室等容期压力最大变化速率,T-dp/dtmax为室内压下降段最大变化速率所在时间.数据采用X±SD表示,n=8,*p<0.05,**p<0.01,与给药前比较,数据统计采用配对t检验。
以上实验结果表明,化合物1在0.1-1.0mg/kg对血压及心功能明显影响,高剂量10mg/kg有轻度降低平均动脉压和轻度降低心率的作用;对心脏收缩功能和舒张功能无明显影响。
生物效应实验3的实验方法,Wistar大鼠用戊巴比妥钠麻醉后,颈部腹侧偏右分离右颈总动脉,结扎远心端,右颈总动脉插管,导管中充满0.03%肝素的生理盐水,并与压力换能器和记录仪连接,观察示波器上压力波形的变化;信号输入至SMUP-PC生物信息处理系统,可自动记录平均动脉压和心功能各项指标。操作步骤详见文献:Aguilar-Bryan L,Nichols CG,Wechsler SW,et al.Cloning of theβ cell high-affinity sulfonylurea receptor:A regulation ofinsulin secretion.Science(Wash DC)1995;268;423-6.
