Abstract
本发明叙述了新的茚满和茚衍生物,它们是内皮素受体拮抗剂。
Description
发明的领域
本发明涉及新的茚满(1,2-二氢化茚)和茚衍生物、含有这些化合物的药用组合物以及它们作为内皮素受体拮抗剂的应用。
内皮素(ET)是由血管的内皮合成和释放的非常强的血管收缩剂肽。内皮素以三异构形式ET-1,ET-2和ET-3存在。[除非另有说明,否则“内皮素”是指内皮素异构体中任何一种或所有的异构体]。内皮素对心血管系统(尤其是对冠状的、肾的和大脑的循环)具有奥妙的影响。内皮素的升高或异常的释放与平滑肌的收缩有关,它们涉及心血管、脑血管、呼吸和肾病理生理学的发病机理。据报道,在患有原发性高血压、急性心肌梗塞、蛛网膜下出血、动脉粥样硬化的病人以及进行透析的尿毒症病人的血浆中内皮素含量升高。
在体内,内皮素对血压和心输出量具有奥妙的影响。给大鼠静脉单次快速注射ET(0.1~3nmol/kg),引起短暂的与剂量有关的降压药反应(维持0.5~2分钟),接着出现持久的与剂量相关的动脉血压升高,按照剂量,升高能保持2-3小时。给大鼠的剂量超过3nmol/kg,通常表明是致死的。
内皮素对肾血管床显现优先的影响。它引起肾血流明显的、长期的减少,并伴有GFR、尿容量、尿钠和钾排泄显著的减少。尽量前房促尿钠排泄的肽明显上升,但是内皮素产生持久的尿钠排泄受抑制作用。内皮素还刺激血浆血管紧张肽原酶活性。上述结果启示,ET与肾功能的调节有关,因此它涉及多种肾疾病,包括急性肾衰竭、环孢菌素肾中毒,X射线对照引起的肾衰竭和慢性肾衰竭。
体内研究表明,大脑脉管系统对内皮素的血管舒张和血管收缩的影响均十分敏感。因此,ET可以是大脑血管痉挛、蜘网膜下出血频繁和经常的致命后果重要的传递质。
ET还具有直接的中枢神经系统作用,例如严重的呼吸暂停和局部缺血损伤,这启示ET可以促使大脑梗塞和神经元死亡的出现。
ET还与心肌局部缺血(Nichols等,
Br.J.Pharm.99:597~601,1989和Clozel和Clozel,
Circ.Res.,65:1193-1200,1989)、冠状血管痉挛(Fukuda等,
Eur.J.Pharm.165:301-304,1989和Lüscher,
Circ.83:701,1991)、心衰竭、血管平滑肌细胞的增生(Takagi,
Biochem & Biophys.Res.Commun.168:537-543,1990,Bobek等,
Am.J.Physiol 258:408-C415,1990)以及动脉粥样硬化(Nakaki等,
Biochem. & Biophys.Res.Commun.158:880-881,1989,和Lerman等,
New Eng.J.of Med.325:997-1001,1991)有关。在冠状气囊血管成形术之后内皮素的含量增加(Kadel等,No.2491
Circ.82:627,1990)。
此外,已发现内皮素是分离的哺乳动物导气管组织(包括人支气管)有力的缩窄剂(Uchida等,
Eur.J.of Pharm.154:227-2281988,LaGente,Clin.
Exp.Allergy 20:343-348,1990;和Springall等,
Lancet,337:697-701,1991)。内皮素可以在间隙肺纤维变性和有关的肺压力过高的发病机理中起作用(Glard等,Third International Conference on Endothelin,1993,P.34和ARDS(Adult Respiratory Distress Syndrome),Sanai等,上文,p.112)。
内皮素与诱导胃粘膜出血和坏死性损伤(Whittle等,
Br.J. Pharm.95:1011-1013,1988)、雷诺现象(Cinniniello等,Lancet 337:114-115,1991,)、节段性回肠炎和溃疡性结肠炎(Munch等,
Lancet,Vol.339,p.381)、偏头痛(Edmeads,Headache,Feb.1991,p127)、脓毒症(Weitzberg等,
Circ.Shock 33:222-227,1991;Pittet等,
Ann.Surg.213:262-264,1991)、环孢菌素引起的肾衰竭或高血压
(Eur.J.Pharmacol.,180:191-192,1990,
Kidney Int,37:1487-1491,1990)、内毒素休克和其他的内毒素引起的疾病(
Biochem.Biophys.Res.Commun.,161:1220-1227,1989,Acta
Physiol.Scand.137:317-318,1989)以及炎性皮肤疾病(
Clin Res.41:451和484,1993)有关。
内皮素还涉及妊娠的Preclampsia(Clark等,
Am.J.Obstet.Gynecol.March 1992,p.962~968:Kamor等,
N.Eng.J.of Med.,Nov 22,1990,p.1486-1487;Dekker等,Enr J.Ob.andGyn.and Rep.Bio.40(1991)215~220;Schiff等,
Am.J.Ostet.Gynecol.Feb 1992,p.624-628)、糖尿病(Takahashi等,Diabetologia(1990)33:306-310)以及肾移植后的急性血管排斥(Watschinger等,
Transplantation Vol.52,No.4,pp.743-746)。
内皮素可促进骨骼吸收和合成代谢,因此可以在骨骼重新塑造的偶联中起作用(Tatrai等,
Endocrinology,Vol.131,p.603-607)。
据报道,内皮素具有促进子宫腔中精子转移的作用(Casey等,J.Clin.Endo and Metabolism,Vol.74,No.1,p.223-225),因此内皮素拮抗剂可以用作为男性避孕剂。内皮素可调整卵巢的/月经的循环(Kenegsberg,
J.of Clin.Endo.and Met.,Vol.74,No.1,p.12),因此它可以在调整男性阴茎血管正常力度和张力中起作用(Lau等,Asia Pacific J.of Pharm.,1991,6:287-292和Tejada等,
J.Amer.Physio.Soc.1991,H1078-H1085)。内皮素还可以传递人前列腺平滑肌有力的收缩(Langenstroer等,J.Urology,Vol,149,p.495-499)。
因此,内皮素受体拮抗剂可对下列疾病提供独特的药物疗法:高血压、肾衰竭、局部缺血引起的肾衰竭、脓毒症-内毒素引起的肾衰竭、预防和/或治疗放射性对照引起的肾衰竭、急性和慢性环孢菌素引起的肾衰竭、脑血管疾病、心肌局部缺血、心绞痛、心衰竭、哮喘、冠状动脉粥样硬化、雷诺现象、溃疡、脓毒症、偏头痛、青光眼、内毒素休克、内毒素引起的多组织衰竭或播放的血管内凝结。环孢菌素引起的肾衰竭、在血管成形术中作为预防再狭窄的调节剂、糖尿病、妊娠的Preclampsia、骨骼的重新塑造、肾移植、男性避孕剂、不育症和阴茎异常勃起以及良性前列腺肥大。

A)膜制备
将大白鼠小脑或者肾脏皮质迅速解剖取出,并立即在液氮中冷冻,或者趁新鲜立即使用。取1-2克小脑组织或3-5克肾脏皮质,置于含有20mM Tris HCl和5mM EDTA,pH7.5的15ml缓冲液中,在4℃下用电动匀浆器作组织匀浆,匀浆通过干酪包布过滤后,在4℃以20,000xg的转速离心10分钟。分离出上清液,在4℃,以40,000xg的转速再离心30分钟。将所得到的沉淀再次悬浮于少量含有50mM Tris,10mM MgCl2,pH7.5的缓冲液中:并用小玻璃瓶等分分装,在液氮中冷冻。用于结合测定小脑和肾皮质膜制备稀释成每管含1mg和5mg蛋白质。
将新鲜分离出的大白鼠肠系膜动脉和附着的血管床组织在冰冷的生理盐水(在冰上)中洗涤,去除较大血管旁的淋巴结组织。然后用多稳元件(polytron)在含有20mM Tris和5mM EDTA,pH7.5的缓冲液中,在4℃作匀浆,大约6g肠系膜动脉血管床用15ml缓冲液作匀浆。匀浆通过干酪包布过滤后,在4℃以2000xg的转速离心10分钟。取出上清液,再在4℃,以40,000xg的转速离心30分钟。所得到的沉淀以同上述小脑和肾皮质制备的方法,再次悬浮在少量缓冲液中。用于结合试验时每管含膜蛋白大约需10mg。
B([125I]ET-1结合试验方案
将[125I]ET-1和大白鼠小脑膜(2-5mg蛋白质/每个测定管)或肾皮质膜(3-8mg蛋白质/每个测定管)置于50mMTrisHCl,10mM MgCl2,0.05%BSA,pH7.5的缓冲液中(总量100ml),在30℃共同温育60分钟,测定[125I]ET-1对膜的结合作用。将膜蛋白加入含有缓冲液或者含有已标明化合物浓度的试管中。用含有BSA的同样的缓冲液稀释[125I]ET-1(2200ci/mmol),使其最后浓度为0.2-0.5nM ET-1。在加入和不加入100nM未标记的ET-1的情况下,可分别测定总结合量和非特异性结合量。温育完成后,加入3.0ml含有50mM TriS和10mM MgCl2,pH7.5的冷缓冲液,使反应停止。用过滤方法,通过Whatman GF/C滤纸从游离的配体中分离出已结合放射活性的膜蛋白,并用Brandel细胞收集器,以3ml冷缓冲液洗涤滤纸5次。用伽马计数器,以75%的效率对滤纸作计数测定。本发明化合物的IC50′s。范围在0.1nm到50mm之间。

将ET-1诱发的血管收缩反应以60mM KCl诱发反应的百分数来表示,在每次实验开始的时候,对每个组织片段先用60mM KCl测定其诱发的反应。数据以平均数±S.E.M表示。用Arunlakshana和Schild的标准方法测定竞争性拮抗剂的分离常数(Kb)。本发明化合物的效能范围可从0.1nM延伸到50mm。
