Description
本发明涉及通式I的化合物
其中
A选自基团(a)、(b)或(c):
(a)或(b),或是任选被低级烷基取代的环烷基(c);
Ar1是苯基或六元杂芳基;
X1是N或CH;
X2是N-R1或O;
R1是S(O)2-低级烷基,被低级烷基取代的C(O)-环烷基,或是C(O)-低级烷基,低级烷基,氰基,环烷基,或是被低级烷基,氰基,C(O)-低级烷基,卤素,被卤素取代的低级烷基或低级烷氧基取代的六元杂芳基;或是被氰基或卤素取代的苯基;

或涉及其药物活性盐,立体异构形式,包括式I的化合物的单独的非对映异构体和对映体,以及外消旋和非外消旋混合物。
已经发现本发明的化合物是高潜力的NK-3受体拮抗剂,用于治疗抑郁,疼痛,精神病,帕金森病,精神分裂症,焦虑和注意缺陷多动障碍(ADHD)。
三种主要的哺乳动物速激肽,P物质(SP),神经激肽A(NKA)和神经激肽B(NKB),属于神经肽家族,其共享Phe-X-Gly-Leu-Met-NH2的共同COOH-末端五肽序列。作为神经递质,这些肽经由三种不同的神经激肽(NK)受体发挥它们的生物活性,所述三种不同的神经激肽受体称作NK-1,NK-2和NK-3。SP优先结合到NK-1受体上,NKA优先结合到NK-2并且NKB优先结合到NK-3受体。
NK-3受体特征在于在CNS中的优势表达,并且已经表明其参与在中枢单胺能系统的调节中。这些性质使NK-3受体成为用于中枢神经系统疾病如焦虑,抑郁,双相型障碍,帕金森病,精神分裂症和疼痛的潜在靶(Neurosci.Letters,2000,283,185-188;Exp.Opin.Ther.Patents 2000,10,939-960;Neuroscience,1996,74,403-414;Neuropeptides,1998,32,481-488)。
精神分裂症是主要神经精神病之一,特征在于严重和慢性的精神损害。此破坏性的疾病影响约1%的世界人口。症状开始于早期成年期,并且随后是一段时期的人际关系和社交的机能障碍。精神分裂症表现为:听觉和视觉幻觉,偏执狂,妄想(阳性症状),迟钝性情感,抑郁,快感缺乏,言语缺乏,记忆和注意缺陷以及社交病理性退隐(阴性症状)。
几十年来,科学家和临床医生进行了努力,目的在于发现用于药理治疗精神分裂症的理想药物。但是,由于大量症状的疾病复杂性已经阻碍了那些努力。对于精神分裂症的诊断没有特异的病灶性特征,并且在所有患者中没有一致性地存在单一症状。因而,精神分裂症作为单一疾病或作为各种不同的疾病的诊断已经进行了讨论,但是还没有得到解决。开发用于精神分裂症的新药的主要困难在于缺乏关于此疾病的成因和性质的知识。在药理学研究的基础上,为了使相应治疗的开发合理化,已经提出一些神经化学假说:多巴胺,5-羟色胺和谷氨酸盐或酯假说。但是,考虑到精神分裂症的复杂性,对于抗阳性和阴性征兆和症状的功效,可能需要适宜的多受体亲和性分布图。此外,抗精神分裂症的理想药物将优选具有低剂量,从而允许一日一次剂量,原因在于精神分裂症患者的低坚持性。
近年来,采用选择性NK1和NK2受体拮抗剂的临床研究出现在文献中,表明用于治疗呕吐,抑郁,焦虑,疼痛和偏头痛(NK1)和哮喘(NK2和NK1)的结果。最令人激动的数据产生于用NK1治疗化疗诱导的呕吐,恶心和抑郁中和用NK2-受体拮抗剂治疗哮喘中。相反,直到2000年,文献中都没有出现对于NK3受体拮抗剂的临床数据。来自Sanofi-Synthelabo的奥沙奈坦(Osanetant)(SR 142,801)是描述用于NK3速激肽受体的第一个找出的有效和选择性的非肽拮抗剂,用于潜在治疗精神分裂症,其报告于文献(Current Opinion in Investigational Drugs,2001,2(7),950-956和Psychiatric Disorders Study 4,Schizophrenia,June 2003,Decision Recources,Inc.,Waltham,Massachusetts)中。所提出的药物SR 142,801已经于II期试验中显示为针对精神分裂症的阳性症状如行为变化,妄想,幻觉,极端情绪,兴奋性运动活性和语无伦次的言语有活性,但是在治疗阴性症状中是非活性的,所述阴性症状是抑郁,快感缺乏,社交隔离或记忆和注意缺陷。
神经激肽-3受体拮抗剂已被描述为可用于疼痛或炎症,以及用于精神分裂症,Exp.Opinion.Ther.Patents(2000),10(6),939-960和Current Opinionin Investigational Drugs,2001,2(7),950-956956和Psychiatric DisordersStudy4,Schizophrenia,June 2003,Decision Recources,Inc.,Waltham,Massachusetts)。
