技术领域
本发明涉及式(I)的新的mGluR1和mGluR5受体亚型偏好性配体和/或其盐和/或其水合物和/或其溶剂合物,涉及它们的制备方法和用于它们的制备的中间体,涉及含有这些化合物的药物组合物,以及涉及它们在治疗和/或预防需要调控mGluR1和mGluR5受体的病症中的应用。
背景技术
哺乳动物中枢神经系统(CNS)中的主要兴奋性神经递质是谷氨酸分子,它会结合神经元,从而激活细胞表面受体。基于受体蛋白的结构特征、受体将信号转导进细胞中的方式和药理学特性,这些受体可以分成2大类,即离子型和促代谢型谷氨酸受体。
促代谢型谷氨酸受体(mGluR)是G蛋白-偶联受体,它在结合谷氨酸后,激活许多细胞内第二信使系统。完整哺乳动物神经元中mGluR的激活,会引起一种或多种下述反应:磷脂酶C的激活;磷酸肌醇(PI)水解的增加;细胞内钙释放;磷脂酶D的激活;腺苷环化酶的激活或抑制;环磷腺苷(cAMP)形成的增加或减少;鸟苷酸环化酶的激活;环鸟苷酸(cGMP)形成的增加;磷脂酶A2的激活;花生四烯酸释放的增加;和电压-和配体-门控离子通道的活性的增加或降低(TrendsPharmacol.Sci.,1993,14,13;Neurochem.Int.,1994,24,439;Neuropharmacology,1995,34,1;Prog.Neurobiol.,1999,59,55)。
通过分子克隆,已经鉴定了8种不同的mGluR亚型,称作mGluR1至mGluR8(Neuron,1994,13,1031;Neuropharmacology,1995,34,1;J.Med.Chem.,1995,38,1417)。通过某些mGluR亚型的可选剪接形式的表达,产生进一步的受体多样性(PNAS,1992,89,10331;BBRC,1994,199,1136;J.Neurosci.,1995,15,3970)。
基于氨基酸序列同源性、受体使用的第二信使系统、和它们的药理学特征,可以将促代谢型谷氨酸受体亚型细分成3组,即第I组,第II组,和第III组mGluR。第I组mGluR包括mGluR1,mGluR5及其可替代选择的剪接变体。
阐释第I组mGluR的生理学作用的尝试提示,这些受体的激活会引起神经元兴奋。有证据表明,该兴奋是由于突触后mGluR的直接激活,但是还已经暗示发生突触前mGluR的激活,导致增加的神经递质释放(Trends Pharmacol.Sci.,1992,15,92;Neurochem.Int.,1994,24,439;Neuropharmacology,1995,34,1;Trends Pharmacol.Sci.,1994,15,33)。
促代谢型谷氨酸受体已经涉及哺乳动物CNS中的许多正常过程。已经证实,mGluR的激活是诱导海马长时程增强效应和小脑长时程抑制所需的(Nature,1993,363,347;Nature,1994,368,740;Cell,1994,79,365;Cell,1994,79,377)。还已经证实了mGluR激活在伤害感受和镇痛中的作用(Neuroreport,1993,4,879;Brain Res.,1999,871,223)。
已经提出,第I组促代谢型谷氨酸受体和更具体的mGluR5在许多影响CNS的病理生理学过程和病症中起作用。它们包括中风,头损伤,缺氧和缺血性损伤,低血糖症,癫痫,神经变性病症例如阿尔茨海默氏病,急性和慢性疼痛,物质滥用和戒断,肥胖和胃食管返流疾病(GERD)和肠易激综合征(Trends Pharmacol.Sci.,1993,14,13;Life Sci.,1994,54,135;Ann.Rev.Neurosci.,1994,17,31;Neuropharmacology,1995,34,1;J.Med.Chem.,1995,38,1417;Trends Pharmacol.Sci.,2001,22,331;Curr.Opin.Pharmacol.,2002,2,43;Pain,2002,98,1,Curr Top Med Chem.,2005;5(9):897-911)。认为这些病症中的许多病理情况是由于过度的谷氨酸诱导的CNS神经元兴奋。由于第I组mGluR似乎会通过突触后机理和增强的突触前谷氨酸释放来增加谷氨酸介导的神经元兴奋,它们的激活可能促成病理情况。因此,第I组mGluR受体的选择性拮抗剂可能是治疗上有益的,尤其是作为神经保护剂、镇痛药或抗惊厥药。
WO 2006120573涉及抑制哺乳动物癌细胞增殖的方法,包括对所述哺乳动物给予治疗有效量的本发明式(I)化合物的N-氧化物中的杂环一-N-氧化物。

WO 200558834提供了新的喹啉衍生物在治疗肝X受体(LXR)介导的疾病,尤其是多发性硬化,类风湿性关节炎,炎性肠病和动脉粥样硬化中的应用,这些化合物抑制Th-1型淋巴因子产生,导致HDL水平和胆固醇代谢增加。WO 2005058834的通式覆盖了本发明式(I)的化合物中的某些,但仅通过使适当的苯胺衍生物(WO 200558834的方案9中所述)与1,2-双(苯磺酰基)-乙烯反应制备3-苯磺酰基-4-苯基-8-三氟甲基-喹啉。本发明通式不覆盖该化合物并且证实该化合物对mGluR1和mGluR5受体无活性。
WO 200530129涉及用作钾通道抑制剂的化合物。这类化合物可以用作治疗和预防心律失常等的Kv1.5拮抗剂和治疗免疫抑制、自身免疫病等的Kv1.3抑制剂。WO 200530129的通式覆盖了本发明式(I)化合物中的某些,但无法制备本发明式(I)的3-芳基磺酰基-4-芳基-喹啉衍生物或表征其物理特性,仅能够制备2-取代的-6-甲氧基-喹啉-3-腈衍生物或表征其物理特性。
上述公开文献中提及的化合物未公开也未提示对mGluR1和mGluR5受体具有活性。

在含有10%FCS、1%抗生素抗真菌溶液、400μg/ml G418、250μg/ml Zeocin(一种抗生素)、5μg/ml嘌呤霉素的F12培养基中,培养稳定表达重组人mGluR5a受体的中国仓鼠卵巢(CHO)细胞(CHO-mGluR5a,购自Euroscreen)。将细胞保持在37℃、增湿培养箱中,在5%CO2/95%空气气氛下,每周传代3次。以2.5-3.5×104细胞/孔,将细胞接种在标准的96-孔微量培养板上,通过在次日加入600ng/ml多西环素,诱导受体表达。加入诱导剂后16-24小时,进行钙测量。
胞质钙浓度的荧光测量
在原代大脑新皮层和小脑培养物上,和在稳定表达人mGluR5a受体的CHO-mGluR5a细胞上,测量胞质钙浓度([Ca2+]i)。在标准的96-孔微量培养板中培养细胞,在测量前,对细胞装载Ca2+-敏感的荧光染料fluo-4/AM(2μM):神经细胞培养物装载于它们的生长培养基中,CHO-mGluR5a细胞装载于添加了2mM丙酮酸钠和30μg/ml谷氨酸-丙酮酸转氨酶(在CHO-mGluR5a细胞的情况下,这些添加剂也存在于[Ca2+]i测量过程中)的试验缓冲液(145mM NaCl,5mM KCl,2mM MgCl2,2mM CaCl2,10mM HEPES,20mM D-葡萄糖,2mM丙磺舒,pH=7.4)中。通过与100μl/孔染料溶液在37℃、增湿培养箱中、5%CO2/95%空气的气氛下孵育细胞40-120min,完成装载。为了终止染料装载,用试验缓冲液洗涤细胞2次。洗涤后,取决于实验设置,向每个孔中加入不同浓度的实验化合物(由DMSO或二甲基甲酰胺(DMF)储备溶液在试验缓冲液中稀释,终DMSO/DMF浓度<0.1%)或缓冲液。在大脑新皮层培养物的情况下,试验缓冲液还含有TTX(0.5μM,以抑制[Ca2+]i的自发振荡,在小脑培养物的情况下,用磺吡酮(0.25mM)替代丙磺舒。
在37℃孵育10-20min后,用平板读数荧光计(FlexStation II,Molecular Devices)逐列测量基线和激动剂诱发的[Ca2+]i变化。从平板的底部,进行激发和发射的检测。在37℃进行整个测量过程,用定制的软件控制。通过测量在不同浓度的化合物存在下激动剂诱发的[Ca2+]i升高的降低,评价实验化合物的抑制效力。DHPG用作所有3种培养物的激动剂,对大脑新皮层和小脑培养物的浓度分别是20和100μM。在CHO-mGluR5a细胞的情况下,使用EC80浓度的DHPG,所述EC80-值源自每天测定的剂量-响应曲线。将荧光数据表达为ΔF/F(将荧光变化相对于基线标准化)。
在多个孔中测量对单个培养板的所有处理。将同一处理的所有孔的数据平均化,将平均值用于分析。将在单一浓度点的化合物的抑制效力表达为对对照激动剂响应的抑制百分比。用S形浓度-抑制曲线拟合数据(源自至少3个独立实验),将IC50-值确定为产生化合物导致的最大抑制的一半的浓度。使用Soft Max Pro(Molecular Devices)软件分析原始荧光数据,用GraphPad Prism进行曲线拟合。
