用下述测试方法,可测定式I化合物对内皮素受体的抑制活性:I、对内皮素与人胎盘膜结合的抑制(参见:Life Sci 44:1429
(1989))
将人胎盘在含有1mM MgCl2和250mM蔗糖的5mM三羟甲基氨基甲烷(Tris)缓冲液pH7.4中匀化。该匀化液在4℃和3000g下离心15分钟,将含有血浆膜组分的上层清液在72000g下离心30分钟,用含有25mM MgCl2的75mM Tris缓冲液pH7.4洗涤沉淀,然后,将由每次10g原组织得到的沉淀悬浮于含有25mM MgCl2和250mM蔗糖的1ml 75mMTris缓冲液pH7.4中,以1ml等分试样在-20℃下冷冻干燥。
为了进行结合试验,将冷冻干燥的膜制剂溶化,在20℃和25000g离心10分钟后,再悬浮于试验缓冲液(含有25mM MnCl2,1mM EDTA和0.5%牛血清清蛋白的50mM Tris缓冲液pH7.4)中。将100μl含有70μg蛋白的膜悬浮液与50μl 125I-内皮素(比活度2200Ci/mMol)的试验缓冲液(25000cpm,最终浓度20pM)和100μl含有各种浓度的试验化合物的试验缓冲液一起培养。该培养在20℃下进行2小时或在4℃下进行24小时。通过玻璃纤维过滤器过滤分离出游离的和膜结合的放射配体。II、对在分离出的鼠主动脉环中内皮素诱导的收缩的抑制
从成年Wistar-Kyoto鼠的胸主动脉上切取长5mm的环。通过轻轻摩擦内表面除去内皮。在37℃下将各个环浸泡处于隔离的浴中的10ml Krebs-Henseleit溶液中同时鼓泡通入95%O2和5%CO2。测定环的等长张力,在预拉力3g下拉伸环。培养10分钟后,加入试验化合物或载体集累剂量的内皮素-1。通过计算剂量比测定试验化合物的活性,剂量比即被100μM试验化合物诱导的内皮素的EC50的右移(移至较高的值),EC50表示半最大收缩所需的内皮素的浓度。剂量比越大,试验化合物在抑制内皮素-1的生物活性中的功效越大。在没有试验化合物的情况下,内皮素的EC50是0.3nM。III、对鼠的血管收缩的抑制活性
用仲丁硫巴妥钠(100mg/kg i.p.)麻醉鼠,将测量系统动脉血压的导管通过股动脉,并将导管通过股静脉置于静脉腔中以注射试验化合物。将多普勒探子置于左肾动脉旁,并与多普勒测量仪相连。在出口的一端压紧左肾动脉45分钟产生肾局部缺血。在引发局部缺血前10分钟,以剂量5mg/kg动脉内(i.a.)或以剂量l0mg/kg静脉内(i.v.)施用试验化合物。在对照试验中,与局部缺血前的值相比,肾输注被减少43±4%。
用试验方法I测定的式I化合物的抑制活性以IC50值列于表1中,IC50即为抑制50%的125I-内皮素的特定结合所需的浓度[mM]。

优选使用静脉内、肌内或口服给药。以有放量施用的式I化合物的剂量取决于具体活性成分的性质、病人的年龄和需要以及施用方式。一般考虑的剂量为大约0.1-100mg/kg体重/天。含有式I化合物的制剂可含有惰性的或是药物活性的添加剂。例如片剂或颗粒剂可含有各种粘合剂、填充剂、载体或稀释剂。液体制剂可以无菌的与水混溶的溶液形式存在。胶囊剂除含有活性成份外还含有填充剂或增稠剂。另外,还可存在调味添加剂、通常用作防腐剂、稳定剂、保湿剂和乳化剂的物质、用于改变渗透压的盐、缓冲液和其他添加剂。
