技术领域
本发明涉及新的色烯类化合物、其制备方法和包含其的药物组合物。
背景技术
众所周知投射于边缘结构的多巴胺能通路和额皮质在情绪控制、奖赏现象、运动功能和认知中起重要作用。D3多巴胺能受体以高浓度存在于这些皮质和边缘结构诸如伏隔核、苍白球、丘脑和额皮质中,而其密度在纹状体中相对较低。因此,它们是精神药物选择的一个标靶(Psychopharmacology,1998,135,1-16;CNS Neurol.Disord.Drug Targets,2006,5,25-43)。
阻断D2受体使得阳性症状得到改善,但还伴随有僵住症、认知功能降低和可导致抑郁的效应(CNS Drug Discov.,2006,1,271-88;Drug Discov.Today,2005,10,917-25)。尽管阻断D3受体对阳性症状的影响尚未被明确地证明,但其对情绪有有利的影响、改善认知功能并对抗僵住症(Thérapie2008,63,187-229)。
这些发现表明,通过对D3受体的优先的拮抗剂活性和对D2受体的适当的拮抗剂活性具有最佳特性的化合物能处于就精神分裂症所有症状的最佳控制而言的理想的“治疗窗”中,同时其自身没有锥体外系副作用(僵住症)和高选择性地阻断每一种多巴胺能受体所伴随的其他的缺点(DrugDiscov.Today,2005,10,917-25;Thérapie 2008,63,187-229)。
发明内容
基于这些发现和文献中证明多种结论,应理解相对于D2受体而言对D3受体的优选提供了在用作药物时具有重要价值的本发明化合物,所述药 物用于治疗精神分裂症和其他的精神病(Drug Discov.Today,2005,10,917-25;Neurosci.Behav.Rev.,2001,25,427-43),和药物滥用,其包括“再犯”(Brain Res.Rev.,2005,49,77-105;J.Med.Chem.,2005,48,3664-79):例如,精神兴奋药可卡因和苯丙胺(Int.J.Neuropsychopharmacol.,2007,10,167-81;J.Pharmacol.Exp.Ther.,2007,321,573-82)、尼古丁(Neuropsychopharmacol.,2003,28,1272-80;Int.J.Neuropsychopharmacol.,2006,9,585-602)、阿片类(Synapse,2003,48,154-6;Psychopharmacology,2004,175,127-33)和酒精(Pharmacol.Biochem.Behav.,2005,81,190-7;FASEB J.,2007,20,2223-33)。本发明产物还能用于治疗由应激诸如焦虑状态和毒物瘾所引起的病症(Psychopharmacology,2004,176,57-65;Prog.Neurobiol.,2003,70,83-244),用于治疗单相和双相抑郁状态(Eur.Neuropsychopharmacol.,2008,18,271-7;Mol.Interv.,2008,8,230-41),用于治疗冲动行为诸如强迫症(Psychiatry Res.,2003,119,1-10;Am.J.Med.Genet.B Neuropsychiatr.Genet.,2006,141B,409-13)和攻击性(J.Neural.Transm.,2003,110,561-72),当单独施用或与多巴胺能激动剂或L-DOPA联用时用于治疗帕金森病(Neurobiol.Dis.,2009,印刷中;Exp.Neurol.,2004,188,128-38),用于治疗特发性震颤(PNAS,2006,103,10753-8;Brain,2007,130,1456-64)、记忆障碍以及与精神病学和神经病学上的疾病相关的其他认知障碍诸如痴呆和阿尔茨海默病(Psychopharmacology,2005,179,567-75;J.Neurochem.,2007,100,1047-61)、儿童或青少年中的发育障碍诸如自闭症系列障碍和注意缺陷多动症(Biol.Psychiatry,2008,65,625-30),用于治疗疼痛,例如与阿片类相关的疼痛(Psychopharmacology,1999,144,239-47;Prog.Neurobiol.,2002,66,355-474),或还用于治疗由例如细胞毒性剂和多巴胺能激动剂引起的恶心(J.Neural Transm.,1999,105,1045-61;Eur.J.Pharmacol.,1996,301,143-9)。本发明化合物还用于治疗早泄(J.Sex.Med.2009,6,980-8;Br.J.Pharmacol.2008,154,1150-9),还用于肾脏保护,例如与糖尿病相关的或与使用扰乱新陈代谢的抗精神病药长期治疗相关的肾 脏保护(Lab.Investigation,2006,86,262-74;Naunyn Schmiedebergs Arch.Pharmacol.,2005,371,420-7)。

通过竞争性试验使用氚标记的螺哌隆([3H]-螺哌隆)在稳定表达人D3、D2S和D2L多巴胺能受体的CHO细胞膜评价化合物对这3种受体亚型的亲和性。将各种细胞系培养至汇合,然后分离细胞,并使用Polytron在包含5mM MgCl2的Tris-HCl缓冲液(50mM,pH 7.4)中匀化。然后将细胞碎片离心(在4℃15分钟),并将沉淀物溶于适当体积的包含150mM NaCl的HEPES缓冲液(20mM)中,并在-80℃冷冻。在试验当天,将膜置于孵育缓冲液中,其包含50mM Tris(pH 7.4)、120mM NaCl、5mM KCl、2mMCaCl2和5mM MgCl2。然后在0.5nM[3H]-螺哌隆存在下将膜在30℃与被研究的化合物孵育1小时。使用10μM雷氯必利测定非特异性结合。在孵育期的结束时,经由用PEI(0.1%)预处理的Unifilter GF/B型过滤器过滤样品,并用包含120mM NaCl的Tris-HCl过滤缓冲液(50mM,pH 7.4)洗涤几次。加入闪烁液后,使用闪烁计数器对过滤器上保留的放射性进行计数。将通过非线性回归分析得到的等温线以测定IC50值,使用Cheng-Prusoff公式将该值转化为pKi:
Ki=IC50/(1+L/Kd)
其中L表示放射性配体浓度,且Kd是[3H]-螺哌隆对D3、D2S和D2L多巴胺能受体的解离常数(分别为0.26、0.14和0.156)。结果以pKi=-log Ki表示。
实施例B:抑制由多巴胺能激动剂PD128,907诱导的低体温诱导。在Wistar系的雄性大鼠测定基线(直肠)温度,然后通过口服施用测试 的化合物或介质。60分钟后,注射PD128,907(0.63mg/kg,皮下),其为一种D3/D2多巴胺能激动剂。30分钟后,再次测定体温,并计算与基线温度的差别(Δ)。
ID50=抑制剂量50
§与“介质+介质”相比有显著性差异(Student氏检验,P<0.05)
