Abstract
通式(I)的化合物,其中R4,R5代表氢原子或一起形成一个1,3-丁间二烯基,可选择地被一个亚甲二氧基或一个或多个直链或支链C1-4烷基,直链或支链C1-4烷氧基,羟基或卤素原子取代;是强效腺苷A3受体配体优选的拮抗剂。
Description
本发明涉及通式(I)的腺苷A3受体配体,在它们之内的优选的拮抗剂和它们的盐,溶剂化物和同分异构体和包含它们的药物组合物,涉及通式(I)的化合物和它们的盐,溶剂化物和同分异构体的应用,涉及通式(I)的化合物和它们的盐,溶剂化物和同分异构体的制备,而且涉及通式(II)(III)和(IV)的新的中间体并涉及它们的制备。
腺苷是若干内源性分子(ATP,NAD+,核酸)中一种众所周知的成分。而且,它在许多生理过程中起很重要的调控作用。腺苷对心脏功能的影响已经在1929年被发现。(Drury和Szentgyrgyi,JPhysiol 68:213,1929)。由腺苷调控的生理功能的增加的数量的鉴别和新的腺苷受体亚型的发现为具体的配体的治疗应用提供了可能性(Poulse,S.A.和Quinn,R.J.Bioorganic and Chemistry 6:619,1998)。
迄今为止,腺苷受体已经被分为三大类:A1,A2和A3。A1亚型部分地负责通过与GI膜蛋白质耦合来抑制腺苷酸环化酶,部分地影响其它第二信使系统。A2受体亚型能被细分成两种更进一步的亚型-A2a和A2b-,这些受体刺激腺苷酸环化酶活性。腺苷A3受体序列最近已经从大鼠睾丸cDNA库中被鉴别出来。随后,被证实它相应于一种新的,功能性的腺苷受体。A3受体的活化也与若干第二信使系统有关:腺苷酸环化酶的抑制,磷脂酶C和D的刺激。
腺苷受体在若干器官中被发现并且调节它们的功能。A1和A2a受体都在中枢神经系统和心血管系统中起重要的作用。在CNS中,腺苷抑制突触的递质的释放,此作用由A1受体调控。在心脏中,A1受体也调控腺苷的负性变力的,变时的和变传导的作用。腺苷A2a受体相对地以较高的量位于纹状体中,在调控突触的传导中显示与多巴胺受体的功能的相互作用。在内皮的和平滑肌细胞上的A2a腺苷受体负责腺苷诱导的血管舒张。
在mRNA识别的基础上,A2b腺苷受体广泛地分布在不同的组织中。它们几乎在每一种细胞亚型中已经被识别了,但是它的表达在肠和膀胱中是最大的。这一亚型可能也在血管紧张性的调控中有重要的调控功能和在肥大细胞的功能中起作用。
与A1和A2a受体相反,在组织分布被发现在蛋白质水平的地方,A2b和A3受体的存在被发现基于它们的mRNA水平。A3腺苷受体的表达水平与其它亚型相比是相当低并且高物种依赖的。A3腺苷受体基本上在中枢神经系统,睾丸,免疫系统中表达并且好像涉及在速发过敏性反应中从肥大细胞的介质释放的调节。
迄今为止在著作中公布的A3拮抗剂有黄酮类,1,4-二氢吡啶衍生物,三唑喹唑啉,噻唑萘啶和噻唑嘧啶。本发明涉及一种有效的A3拮抗剂的新的类型,它具有氨基喹啉结构。
为了治疗应用,很重要的是确保分子不与或只在非常高的浓度的情况下与腺苷受体的A1和A2a和A2b亚型结合。本发明涉及通式(I)的化合物和它们的盐,溶剂化物和同分异构体,它们对于腺苷受体的A3亚型具有高选择性。
我们的目标是首先制备具有喹啉结构的A3配体,和在它们内的优选的拮抗剂,其具有强效的拮抗效应并且对A3受体显示高选择性,也就是他们以远低于抑制A1,A2a和A2b受体的浓度来抑制A3受体。进一步的目标是有稳定性,生物利用度,治疗指数和毒性数据,它们使得将新的化合物开发成药物物质成为可能并且由于它们的有利的肠内吸收这些化合物能被口服应用。

结果
我们将化合物认为是生物学上有活性的化合物如果它们在我们的试验条件下在1μM具有高于80%的活性抑制放射性配体在人类腺苷A3受体上的结合。
在CHO-hA3膜制剂上的[125I]AB-MECA的解离常数(Kd)通过在Scatchard分析的帮助下的同位素饱和度研究来决定((G.Scatchard,Ann.N.Y.Acad.Sci.51:660,1949))。IC50通过应用Cheng-Prusoff方程式被转化成一个亲和常数(Ki)(Y.J.Cheng和W.H.Prusoff,Biochem.Pharmacol.22:3099,1973)。
通式(I),(II),(III)和(IV)的一些化合物显示显著的生物活性。通式(IA)的化合物(在权利要求2中定义),作为通式(I)的子群(在权利要求1中定义),发挥最重要的活性。除5化合物之外,他们的Ki值不高于20nM。作为实施例给出的化合物是特别有利的。它们的在人类腺苷A3受体结合研究中的Ki值在0.19和0.69nM之间。最有利的化合物的Ki值在0.14和0.15nM之间。
这些化合物具有适当的生物利用度并且发挥关于人类腺苷A1,A2a和A2b受体亚型至少10,000-倍的选择性。
进一步,它们的静脉内和口服给药的作用的持续时间是足够长的,它们的ED50值低,他们的毒理学的和副作用的情况是有利的。
上面的数据使得通式(I)的化合物能用作治疗应用。
