另一方面,本发明提供了式I化合物及其盐的制备方法,该方法包括以下步骤:
a)为制备其中X为O、Y为N且Z为N的式I化合物,使式II化合物
其中R2和W如上定义,
与式III化合物反应
其中R1如上定义,或者
b)为制备其中X为O、Y为CH且Z为N的式I化合物,使式IV化合物
其中R2和W如上定义,Hal指卤素,
与式III化合物反应,或者
c)为制备其中X为O、Y为N且Z为CH的式I化合物,使式V化合物
其中R2和W如上定义,
与式VI化合物反应
其中R1如上定义,或者
d)为制备其中X为N、Y为O且Z为CH的式I化合物,使式VII化合物
其中R2和W如上定义,
与式VIII化合物反应
其中R1如上定义。
这些反应可通过已知的方法进行,例如对于a)项下的反应如实施例1所述,对于b)项下的反应如实施例6所述,对于c)项下的反应如实施例10所述,对于d)项下的反应如实施例14所述。
其中R1为氨基的式I化合物可由相应的其中R1为羟基的化合物通过按照常规方法形成酰胺来制备,如实施例5所述。其中R1为CH3-CO-CH2-O-或C(CH3)3-CO-CH2-O-的式I化合物可由相应的其中R1为羟基的化合物通过按照常规方法分别与1-氯-丙-2-酮或1-溴-3,3-二甲基-丁-2-酮反应来制备,如实施例6所述。
对反应混合物进行处理,并将由此所得的化合物用已知的方法纯化。
盐可以通过已知的方法从游离化合物制备,反之亦然。
式II、III、IV、V、VI、VII和VIII的起始化合物是已知的,或者可以通过与已知方法类似的方法来制备。
式I化合物及其可药用盐(下文称为本发明的药物)在体外经Nurr1表达细胞培养物测试和体内测试中显示出有价值的药理学特性,因此可以用作药物。
已知核受体Nurr1与发育中动物或成年动物的中脑多巴胺能神经元机能分化有因果关系。在Nurr1敲除动物的中脑前侧所观察到的多巴胺能神经元缺陷与帕金森氏病中神经元变性的模式相似,在帕金森氏病中初级运动缺陷由黑质多巴胺能系统变性引起(等,1997;Castillo等,1998以及Saucedo-Cardenas等,1998)。因此,Nurr1激活剂被建议用于预防或延迟帕金森氏病症状的出现。
本发明的药物与Nurr1受体的亲和力可以通过体外结合研究来测定:
记录在大肠杆菌(E.Coli.)中表达的Nurr1的均匀15N-标记配体结合域(LBD)的二维1H-15N相关谱(HSQC)。通过指示配体结合的化合物滴定,该光谱可以提供蛋白质结构指纹和二维谱中某些交叉峰确切位置的变化。
在该分析法中,当本发明的药物的浓度为300μM时,使用50μM均匀15N-标记Nurr1 LBD可以在某些峰中观察到化学位移变化。
本发明的药物在Nurr1受体处的活性可通过体外细胞分析法来测定:
本发明的药物对Nurr1受体生物活性的诱导作用可通过中脑多巴胺能细胞系中的Nurr1反应性报道基因的转活来测定。该分析法基于Nurr1的转录促进作用。该报道基因既可以被Nurr1单体激活也可以被Nurr1/RXR异二聚体激活。RXR是核受体常见的异二聚化配偶体,已经证明Nurr1可以与RXR形成异二聚体(RH等,Mol.Endocrinol.1996;10:1656-1666)。
在该分析中,本发明的药物在约1至约1000nM的EC50处呈剂量依赖性地显著增强报道基因的活性。
在以下分析中,本发明的药物在口服剂量为5至30mg/kg时可显著升高体内中脑多巴胺水平:
OF1小鼠用受试化合物处理5天,在最后一次给药5小时后处死小鼠。测量黑质和纹状体组织钻取物(punch)中的多巴胺水平。每组处理10只动物。
因此,本发明的药物可用于治疗帕金森氏病。
此外,一些式I化合物可以作为其它式I化合物的前药,例如其中R1为C1-4烷氧基或苄氧基的化合物可在生理条件下在某种程度上水解为其中R1为羟基的相应的式I化合物。因此,更广义而言,本发明还包括式I化合物的前药。
对于以上提及的适应症,合适的剂量当然根据例如所采用的化合物、宿主、施用方式以及所治疗病症的性质和严重程度而有所不同。但是一般来讲,在动物中日剂量为约0.1至约500、优选约0.5至约100mg/kg动物体重时可获得令人满意的结果。在较大的动物例如人类中,所指明的日剂量为约1至约500、优选约1至约300mg的本发明的药物,方便地以例如至多一日四次的分开剂量或以缓释形式施用。
本发明的药物可以以游离形式施用或以可药用盐的形式施用。所述盐可以通过常规方法制备,并表现出与游离化合物相同级别的活性。
本发明的化合物可通过任何常规途径施用,特别是肠内途径(优选口服途径,例如以片剂或胶囊形式施用)或胃肠道外途径(例如以注射溶液或悬浮液的形式)。
或者,本发明的药物可以例如以乳剂、凝胶等形式局部施用,或经吸入例如以干粉形式施用。
含有本发明的药物的组合物的实例包括例如本发明的药物的固体分散体、水溶液(例如含有增溶剂)、微乳剂以及悬浮液。可以使用适宜的缓冲剂使组合物的pH缓冲至例如3.5至9.5之间。
本发明的药物可单独施用或与其它对于治疗帕金森氏病有效的药物活性剂组合施用。
因此,本发明的药物可以与例如多巴胺前体(例如各种左旋多巴制剂)、多巴胺受体激动药(例如溴隐亭、普拉克索)、儿茶酚-O-甲基转移酶抑制剂(例如恩他卡朋、托卡朋)、B型单胺氧化酶抑制剂(例如司来吉兰)、NMDA拮抗剂(例如金刚烷胺)以及抗胆碱能药(例如比哌立登、奥芬那君(Orphenedrine))组合用于治疗帕金森氏病。
根据前述,本发明还提供了本发明的药物在制备用于治疗帕金森氏病的药物中的用途。
此外,本发明还提供了如下的药用组合物:该组合物含有新的游离碱或可药用的酸加成盐形式的式I化合物,以及至少一种药用载体或稀释剂。这样的组合物可通过常规方法制备。单位剂型含有例如约0.25至约150mg、优选0.25至约25mg的化合物。
用于分别施用组合组分以及用于以固定组合(即含有至少两种本发明的组合组分的单一盖仑组合物)施用的药物组合物可通过本身已知的方法制备,且因此适用于向哺乳动物、包括人类经肠内途径(如口服或直肠途径)和胃肠道外途径施用,它仅含有治疗有效量的至少一种药理活性组合组分或者还含有一种或多种可药用载体,尤其是适于经肠内或胃肠道外施用的载体。
具体而言,治疗有效量的每种组合组分可同时施用或者以任何顺序依次施用,并且组分可以分别施用或者以固定组合施用。
因此,本发明还提供了如下的组合:该组合物含有治疗有效量的新的游离碱或可药用酸加成盐形式的式I化合物以及第二种药物,所述的第二种药物可例如用于治疗帕金森氏病。
另外,本发明还提供了新的游离碱或可药用酸加成盐形式的式I化合物作为用于治疗帕金森氏病的药物的用途。
再一方面,本发明还提供了在需要该治疗的个体中治疗帕金森氏病的方法,该方法包括对所述个体施用治疗有效量的新的游离碱或可药用酸加成盐形式的式I化合物。
