Description
技术领域
本发明涉及化学医药技术领域,具体涉及一种环丙烷或者环丙烯类化合物及其应用。
背景技术
应用化学工具对蛋白质进行共价修饰是鉴定、定量和调节这些生物分子的有效方法。小分子化合物是研究蛋白质功能的强大工具,可通过形成共价键对蛋白质的功能进行调控,为一些疾病的治疗提供益处,如增强和持续药物的抑制作用。然而,大多数人类蛋白质因缺乏小分子配体而无法备用于药物设计。蛋白质特定位点的选择性修饰是解决上述问题的有效途径之一。目前最为广泛的选择性修饰为基于半胱氨酸残基修饰的小分子研究,常见的半胱氨酸导向弹头有丙烯酰胺、氯乙酰胺、碘乙酰胺以及通过芳香族亲核取代的杂芳砜类。但是这些弹头的反应性有所差别,同时反应性可以由所采用的亲电试剂的多个方面调节。新的反应性弹头将有助于开发具有理想反应性分布的共价抑制剂。

具体实施方式
本发明所述化合物中,当任何变量(例如R6等)在任何组分中出现超过一次,则其每次出现的定义独立于其它每次出现的定义。同样,允许取代基及变量的组合,只要这种组合使化合物稳定。自取代基划入环系统的线表示所指的键可连接到任何能取代的环原子上。如果环系统为多环,其意味着这种键仅连接到邻近环的任何适当的碳原子上。要理解本领域普通技术人员可选择本发明化合物的取代基及取代型式而提供化学上稳定的并可通过本领域技术和下列提出的方法自可容易获得的原料容易的合成的化合物。如果取代基自身被超过一个基团取代,应理解这些基团可在相同碳原子上或不同碳原子上,只要使结构稳定。
本文所用短语“Rf取代”,“R取代”,以及划入环系统的“Rf”被认为与短语“被至少一个取代基取代”相当,且在此情况下优选的实施方案将具有1-5个取代基。
本文所用术语“烷基”意指包括具有特定碳原子数目的支链的和直链的饱和脂肪烃基。例如,“C1-C6烷基”中“C1-C6”的定义包括以直链或支链排列的具有1、2、3、4、5或者6个碳原子的基团。例如,“C1-C6烷基”具体包括甲基、乙基、正丙基、异丙基、正丁基、叔丁基、异丁基、戊基、己基。
术语“烷氧基”指具有-O-烷基结构的基团,如-OCH3、-OCH2CH3、-OCH2CH2CH3、-O-CH2CH(CH3)2、-OCH2CH2CH2CH3、-O-CH(CH3)2等。
术语“杂环基”为饱和或部分不饱和的单环或多环环状取代基(包括单环、螺环、并环、稠环、桥环等),其中一个或多个环原子选自N、O或S(O)m(其中m是0-2的整数)的杂原子,其余环原子为碳,其中含氮杂环基是指至少一个环原子为N。例如:等。
术语“杂芳基”指含有1、2或3个选自O、N或S的杂原子的芳香环,本发明范围内的杂芳基包括但不限于:喹唑啉、喹啉基、吡唑基、吡咯基、噻吩基、呋喃基、吡啶基、嘧啶基、吡嗪基、三氮唑基、咪唑基、噁唑基、异噁唑基、哒嗪基等。
正如本领域技术人员所理解的,本文中所用“卤素”(“halo”)或“卤”意指氯、氟、溴和碘。
本发明包括式(I)~式(V)化合物的游离形式,也包括其药学上可接受的盐及立体异构体。本发明所述立体异构体,即(取决于其结构)作为对映体、非对映体、顺型/反型异构体(syn-/anti-isomer)、顺式/反式(cis-/trans-isomer)异构体、差向异构体以及(E)-/(Z)-异构体。式(I)~式(V)化合物可以以纯立体异构体的形式或者以立体异构体的任何混合物的形式用于本发明的上下文中,在后一种情况中优选外消旋体。
术语“游离形式”指以非盐形式的胺类化合物。包括在内的药学上可接受的盐不仅包括本文所述特定化合物的示例性盐,也包括所有式(I)~式(V)化合物游离形式的典型的药学上可接受的盐。可使用本领域已知技术分离所述化合物特定盐的游离形式。例如,可通过用适当的碱稀水溶液例如NaOH稀水溶液、碳酸钾稀水溶液、稀氨水及碳酸氢钠稀水溶液处理该盐使游离形式再生。游离形式在某些物理性质例如在极性溶剂中溶解度上与其各自盐形式多少有些区别,但是为发明的目的这种酸盐及碱盐在其它药学方面与其各自游离形式相当。
可通过常规化学方法自含有碱性部分或酸性部分的本发明化合物合成本发明的药学上可接受的盐。通常,通过离子交换色谱或通过游离碱和化学计算量或过量的所需盐形式的无机或有机酸在适当溶剂或多种溶剂的组合中反应制备碱性化合物的盐。类似的,通过和适当的无机或有机碱反应形成酸性化合物的盐。
因此,本发明化合物的药学上可接受的盐包括通过碱性本发明化合物和无机或有机酸反应形成的本发明化合物的常规无毒盐。例如,常规的无毒盐包括得自无机酸例如盐酸、氢溴酸、硫酸、氨基磺酸、磷酸、硝酸等的盐,也包括自有机酸例如乙酸、丙酸、琥珀酸、乙醇酸、硬脂酸、乳酸、苹果酸、酒石酸、柠檬酸、抗坏血酸、扑酸、马来酸、羟基马来酸、苯乙酸、谷氨酸、苯甲酸、水杨酸、对氨基苯磺酸、2-乙酰氧基一苯甲酸、富马酸、甲苯磺酸、甲磺酸、乙烷二磺酸、草酸、羟乙基磺酸、三氟乙酸等制备的盐。
如果本发明化合物为酸性的,则适当的“药学上可接受的盐”指通过药学上可接受的无毒碱包括无机碱及有机碱制备的盐.得自无机碱的盐包括铝盐、铵盐、钙盐、铜盐、铁盐、亚铁盐、锂盐、镁盐、锰盐、亚锰盐、钾盐、钠盐、锌盐等。特别优选铵盐、钙盐、镁盐、钾盐和钠盐。得自药学上可接受的有机无毒碱的盐,所述碱包括伯胺、仲胺和叔胺的盐,取代的胺包括天然存在的取代胺、环状胺及碱性离子交换树脂例如精氨酸、甜菜碱、咖啡因、胆碱、N,N'-二苄基乙二胺、二乙胺、2-二乙基氨基乙醇、2-二甲基氨基乙醇、氨基乙醇、乙醇胺、乙二胺、N-乙基吗啉、N-乙基哌啶、葡萄糖胺、氨基葡萄糖、组氨酸、羟钴胺、异丙基胺、赖氨酸、甲基葡萄糖胺、吗啉、哌嗪、哌啶、呱咤、多胺树脂、普鲁卡因、嘌呤、可可碱、三乙胺、三甲胺、三丙胺、氨基丁三醇等。
Berg等,“Pharmaceutical Salts”J.Pharm.Sci.’1977:66:1-19更详细描述了上文所述药学上可接受的盐及其它典型的药学上可接受的盐的制备。
由于在生理条件下化合物中脱质子化的酸性部分例如羧基可为阴离子的,而这种带有的电荷然后可被内部带有阳离子的质子化了的或烷基化的碱性部分例如四价氮原子平衡抵消,所以应注意本发明化合物是潜在的内盐或两性离子。
本发明提到的上述特征,或实施例提到的特征可以任意组合。本发明说明书所揭示的所有特征可与任何组合物形式并用,说明书中所揭示的各个特征,可以被任何提供相同、均等或相似目的的替代性特征取代。因此除有特别说明,所揭示的特征仅为均等或相似特征的一般性例子。
下面结合具体实施例,进一步阐述本发明。应理解,这些实施例仅用于说明本发明而不用于限制本发明的范围。下列实施例中未注明具体条件的实验方法,通常按照常规条件如Sambrook等人,分子克隆:实验室手册(NewYork:Cold Spring Harbor LaboratoryPress,1989)中所述的条件,或按照制造厂商所建议的条件。除非另外说明,否则百分比和份数按重量计算。
除非另行定义,文中所使用的所有专业与科学用语与本领域技术人员所熟悉的意义相同。此外,任何与所记载内容相似或均等的方法及材料皆可应用于本发明方法中。文中所述的较佳实施方法与材料仅作示范之用。
