Description
本发明涉及一组氢化诺卜醇取代的苯并咪唑酮和喹唑啉酮衍生物,其为人类ORL1(伤害感受蛋白)受体的激动剂。本发明还涉及这些化合物的制备,含有药理学活性量的这些新苯并咪唑酮和喹唑啉酮衍生物中的至少一种作为活性成分的药物组合物,以及这些药物组合物在治疗涉及ORL1受体的病症中的用途。
‘类阿片样物质受体1’(ORL1)受体从人类cDNA库中鉴别出来。已确定这种‘孤儿受体’与μ-,κ-和δ-阿片样物质受体具有近的同源性(Mollereau等人,
FEBS Lett.,
341,33-38,1994;Bunzow等人,
FEBS Lett.,
347,284-288,1994)。尽管其与阿片样物质受体具有接近的序列和结构相似性,但传统的阿片样物质受体配体不与ORL1受体相互作用。在1995年,从脑的提取物中提纯得到了一种17-氨基酸神经肽,随后其被证明是G蛋白耦合的ORL1受体的天然配体(Reinscheid等人,
Science,
270,792-794,1995;Meunier等人,Nature,
377,532-535,1995)。这种肽被命名为orphanin FQ或伤害感受蛋白,它不与三个传统的阿片样物质受体结合。这些发现引发了对于ORL1受体的功能性作用和其新配体的深入研究。这导致了数百篇文献的公开,包括一些综述(见例如,Grond等人,
Anaesthesist,
51,996-1005,2002),和许多专利申请,其中描述了在药效和选择性(ORL-1对μ-阿片剂)方面不同的肽和非肽配体。由于μ-阿片剂受体广泛地分布于全身,缺少选择性可导致一系列不希望的类阿片剂的副作用,例如镇静,呼吸压抑,耐受性和依赖性(
Drug News Perspect,14,335,2001)。六篇与ORL1有关的专利申请涉及苯并咪唑酮衍生物:WO 98/54168,WO 99/36421,WO 00/006545,WO 00/08013,WO 01/39775和US 20020128288。
与本发明最接近的现有技术是WO 01/39775。然而,其中所描述的苯并咪唑酮衍生物似乎不能满足对于有用的基于ORL1的治疗剂通常被认为重要的标准。它们的特点在于:
(1)温和的药效(与ORL1受体亲合性在166-1252nM的范围内);
(2)没有对μ-阿片剂受体的选择性(亲合性在19-457nM的范围);
(3)没有口服后有效性的证据,和
(4)没有CNS-有效性的证据。
令人惊讶地,现已发现在一系列氢化诺卜醇基取代的苯并咪唑酮和喹唑啉酮衍生物中,一组化合物显示出具有非常高的对人类ORL1受体的亲合性。而且,这些化合物显示了相对于μ-阿片剂受体出色的ORL1受体选择性,口服给药后可容易地起效并可通过血脑屏障。

所述化合物对人类ORL1受体的亲合性用Ardati等人,
Mol. Pharmacol.,51,816,1997所述的体外受体结合试验确定。简要地说,膜制备物是由人的ORL1受体在其中被稳定地表达的CHO(中国仓鼠卵巢)细胞得到的。将膜用[3H]-伤害感受蛋白在没有试验化合物存在或在在适宜的缓冲液中稀释成不同浓度的试验化合物存在下培养。
非特异性的结合定义为在10-6M伤害感受蛋白存在下的残留结合。通过Packard GF/B玻璃纤维过滤器过滤,使用Packard细胞收集器,用冰冷的缓冲液洗涤数次,进行结合放射性与游离放射性的分离。用闪烁计数器(Topcount,Packard),使用液体闪烁混合剂(Microscint 0,Packard)测定结合放射性。将测定的放射性对置换的试验化合物浓度做图,并通过四参数逻辑回归计算置换曲线,得到IC50值,即50%的放射性配体被置换时的替换化合物浓度。亲合性pKI值通过用放射性配体浓度校正IC50值计算,且其对人的ORL1受体的亲合性按照Cheng-Prusoff方程式计算:
pKI=-log(IC50/(1+S/Kd))
其中IC50如上所述,S为试验中所使用的[3H]-伤害感受蛋白浓度,以mol/L表示(典型地0.2nM),而Kd为[3H]-伤害感受蛋白与人ORL1受体(0.4nM)的平衡离解常数。
本发明的化合物在如上所述的结合试验中具有对ORL1受体的高亲合性。该性质使它们可用于治疗其中涉及ORL1受体的病症,或可通过这些受体的控制来治疗的病症。
与μ-阿片剂受体的亲合性
化合物与μ-阿片剂受体的亲合性用Childers等人,
Eur.J. Pharm,55,11,1979所述的体外受体结合试验确定。简要地说,膜制备物由人的μ-阿片剂受体在其中被稳定地表达的CHO-细胞得到,并用[3H]-纳洛酮在没有试验化合物存在或在在适宜的缓冲液中稀释成10μM往下至0.1nM的浓度范围的试验化合物存在下培养。非特异性的结合定义为在10-7M洒石酸利瓦洛凡存在下的残留结合。如上所述进行结合放射性与游离放射性的分离,且化合物的亲合性以类似方式,用1nM的[3H]-纳洛酮浓度(S)和1.3nM的Kd值计算。
在如上所述的结合试验中,本发明的大部分化合物具有低的μ-阿片剂受体亲合性:典型地比它们与ORL1受体的亲合性低100倍。因此它们不会引起不希望的、已知用阿片剂例如吗啡会发生的副作用。
体外ORL1受体激动活性
G蛋白耦合的ORL1受体的活化会抑制腺苷酸环化酶的活性并降低第二信使cAMP的细胞内浓度。使用Jenck等人,
Proc.Natl.Acad.Sci USA,97,4938-4943,2000所描述的试验方法测定所述化合物在ORL1受体上的活性。它们被证明是有效的激动剂,其pEC50-值与它们的pKi值相匹配。
体内ORL1受体激动活性
在如Molewijk等人,
Psychopharmacology,117,32-40,1995中所描述的有条件的超声损伤发声方法中,腹膜内和/或口服给药后本发明的化合物显示出具有高的活性。这不仅证明了所述化合物在口服给药后具有良好的生物利用度,而且证明它们可通过血脑屏障。在此试验中,肽伤害感受蛋白也是活性的,但需要直接在脑中给药(通过脑室内注射)才能证明其作用。
