Abstract
本发明涉及作为酪氨酸激酶抑制剂的新型的酰胺基杂芳基芳酰基酰肼乙炔、其制备方法、以及所述化合物在制备用于治疗性治疗与人类酪氨酸激酶相关的疾病的药物组合物中的应用。
Description
相关应用
本申请要求在2015年5月18日提交的印度专利申请号1953/MUM/2015的权益,其在此通过引用并入。
技术领域
本申请涉及作为酪氨酸激酶抑制剂的新型酰胺基杂芳基芳酰基酰肼乙炔(amidoheteroaryl aroyl hydrazide ethynes)、其制备方法、以及所述化合物在制备用于治疗性治疗与人类酪氨酸激酶相关的疾病(disorders)的药物组合物中的应用。
背景技术
蛋白质酪氨酸激酶目前被认为是用于治疗几种疾病特别是治疗增殖疾病的药物开发的重要分子目标。酪氨酸激酶活性的失调已经出现作为主要机制,通过该机制癌细胞逃避对生长、增殖和存活的正常生理约束。在抗TK药物发现中关键聚焦领域之一是小分子的设计和开发,这种小分子可以通过干涉ATP或底物的结合直接抑制该激酶的催化活性。TK定向治疗的重要优势是实施药效动力学研究的可能性,该研究将癌细胞中靶向TK的抑制与对药物的临床响应关联。
在以下的专利文献中描述了经典的酪氨酸激酶抑制剂,其主要是目前用于临床的Bcr-Abl激酶抑制剂:
●美国专利号5,521,184(’184专利):列举了4-[(甲基-1-哌嗪基)甲基]-N-[4-甲基-3-[[4-(3-吡啶基)-2-嘧啶基]氨基]-苯基]苯甲酰胺甲磺酸盐(伊马替尼甲磺酸盐,)
●美国专利号7,169,791(’791专利):列举了4-甲基-N-[3-(4-甲基-咪唑-1-基)-5-三氟甲基-苯基]-3-(4-吡啶-3-基-嘧啶-2-基氨基)-苯甲酰胺(尼洛替尼,)
●美国专利号6,596,746(’746专利):列举了N-(2-氯-6-甲基苯基)-2-(6-(4-(2-羟基乙基)哌嗪-1-基)-2-甲基嘧啶-4-基氨基)噻唑-5-甲酰胺(达沙替尼,)
尽管临床上第二代TK抑制剂,也就是尼洛替尼和达沙替尼,已经给对伊马替尼形成抗性的患者提供了另一种治疗选择,但是存在一些与它们的副作用有关的不足之处。特别地,在达沙替尼的情况中,增加的效力可能与不良(untoward)的脱靶毒性有关,这可能与它们对较宽范围的蛋白激酶,如Kit、PDGFR和肝配蛋白受体(EphA2)酪氨酸激酶的抑制活性有关,这些蛋白激酶直接牵涉到造血作用、组织间质液压力控制和血管生成中。这些效果可能为一些与达沙替尼治疗相关的毒性比如骨髓抑制和胸腔积液提供生理的解释。除此之外,具有高效的Abl激酶抑制的治疗对于具有CML的患者的心脏毒性的形成具有效力。
研究显示服用伊马替尼的患者在治疗过程期间形成了对药物的抗性。近期的研究已经提供了对抗性机制更好的理解,这导致了第二代TK抑制剂的开发。尽管临床上第二代TK抑制剂为对伊马替尼治疗形成抗性的患者提供了治疗可选方案,但是具有T315I突变的患者的预后是不好的,因为目前这些市场化的治疗都没有效果。因此关于具有T315I突变的患者的治疗,存在尚未满足的医疗需求。FDA批准高三尖杉酯碱(Omacetaxine(homoharringtonine))用于具有T315I的CML患者。然而,它是静脉药物,具有非特异性作用机制。阿瑞雅德(Ariad)化合物帕纳替尼也被美国FDA批准(AP24534,US8114874),但是具有血栓风险威胁和血管严重变窄的加框警告。其他处在临床阶段的药物候选品包括Deciphera化合物DCC-2036(PCT公开号WO2008/046003)。本申请人以前报道过作为酪氨酸激酶抑制剂的新型二芳基乙炔酰肼,作为WO 2012/098416 A1发表过。
本发明描述了新型的酰胺基杂芳基芳酰基酰肼乙炔,其包含了既是Abl酪氨酸激酶的有效抑制剂又是其突变版本的有效抑制剂的化合物。

环丙烷羧酸[5-(2-甲基-5-[N’-[4-(4-甲基哌嗪-1-基-甲基)-3-三氟甲基苯甲酰]-肼基羰基}苯乙炔基)吡啶-2-基]酰胺;
在用于制备本发明的化合物的方法的一种实施方式中,式I化合物可按照以下一般方案1制备
该方法涉及式III酰肼和式II二芳基乙炔化合物的缩合,其中R1、R2和R3如先前对于式I化合物所定义的,而L是离去基团。优选地,在惰性溶剂中在惰性碱和/或合适的催化剂的存在下实施缩合反应。
处于活化形式的式II化合物(即-C(O)-L),特别地,是酸性卤化物、酯、酸酐或环状酰亚胺。
式II的酯可选自,例如乙烯基酯,其可例如,通过相应的酯和乙酸乙烯酯、氨基甲酰基乙烯基酯进行酯交换或通过用C2-5烷氧乙炔处理而获得。其它活化酯属于脒基类型,比如N,N’双取代的脒基酯(其可例如,通过用合适的N,N’双取代的碳二亚胺,例如N,N’-二环己基碳二亚胺,处理相应的酸而获得),或N,N’双取代的脒基酯(其可例如,通过用N,N双取代的氰胺处理相应的酸而获得),合适的芳基酯,特别地,苯基酯,其适合地通过吸电子取代基来取代(可例如,在缩合试剂比如N,N’-二环己基碳二亚胺的存在下通过用适合取代的酚,例如4-硝基苯酚、2,4,5-三氯苯酚或2,3,4,5,6-五氯苯酚,处理相应的酸而获得)。其它合适的活化酯包括氰基甲基酯(可例如,在碱的存在下通过用氯乙腈处理相应的酸而获得)、硫代酯——特别是未取代的或取代的,例如硝基取代的,苯基硫代酯(可例如,通过用未取代的或取代,如硝基取代的苯硫酚,处理相应的酸,尤其通过酸酐或碳二亚胺法,而获得),氨基酯或酰胺基酯(可例如,通过用N-羟氨基或N-羟酰胺基化合物,例如,N-羟基琥珀酰亚胺、N-羟基哌啶、N-羟基邻苯二甲酰亚胺或1-羟基苯并三唑,处理相应的酸,例如通过酸酐或碳二亚胺法,而获得)。
式II化合物的酸酐可以伴随着碳酸半衍生物,例如相应的酯,例如碳酸烷基半酯一起形成(可例如,通过用卤代甲酸,如氯甲酸,处理相应的酸而获得);烷基酯或伴随着1-烷氧基羰基-2-烷氧基-1,2-二氢喹啉,例如1-烷氧基羰基-2-乙氧基-1,2-二氢喹啉一起形成;酸酐伴随着二卤代的,特别是二氯化的磷酸一起形成(可例如,通过用磷酰氯处理相应的酸而获得),或酸酐伴随着有机酸一起形成,如混合酸酐伴随着有机羧酸一起形成(可例如,通过用未取代的或取代的酰基卤,例如新戊酰氯或三氯乙酰氯,处理相应的酸而获得)。酸酐也可以伴随着有机磺酸一起形成(可例如,通过用合适的有机磺酸卤化物,如烷烃-或芳基-,例如甲烷-或对甲苯磺酰氯,处理相应的酸的盐,如碱金属盐,而获得),或伴随着有机膦酸一起形(可例如,通过用合适的有机膦酸酸酐或膦腈处理相应的酸而获得)。
合适的环状酰胺是,特别地,带有五元芳香特征的双氮杂环的酰胺,如咪唑类(其可例如,通过用N,N’-羰基二咪唑处理相应的酸而获得;咪唑烷(imidazolide)方法),或吡唑类,例如3,5-二甲基吡唑。
处于活化形式的式II优选地从相应的酸(即,当L=OH时)原位生成。例如,N,N’双取代的脒基酯可在合适的缩合试剂如N,N’-二环己基碳二亚胺的存在下通过使式II酸(即,当L=OH时)与式III化合物的混合物反应而原位形成。酸的反应性混合酸酐还可以在合适的碱,如三乙胺或4-(N,N-二甲基氨基)吡啶的存在下通过与丙基膦酸酸酐或二乙基氰基膦酸酯反应,伴随着有机膦酸一起原位生成。该反应可以通过本身已知的方式进行,反应条件特别地取决于式II酸性基团如何活化——通常在有合适的溶剂或稀释剂或其混合物的情况下,以及,如果有必要的话,在缩合试剂的存在下。惯常的缩合试剂是,例如,碳二亚胺如N,N’-二乙基-、N,N’-二异丙基、N,N’-二环己基-或N-乙基-N’-(3-二乙基氨基丙基)-碳二亚胺;合适的羰基化合物,例如羰基二咪唑,或1,2-唑化合物,例如2-乙基-5-苯基-1,2-唑3’-磺酸酯和2-叔-丁基-5-甲基-异唑高氯酸酯,或合适的酰胺基化合物,例如,2-乙氧基-1-乙氧基羰基-1,2-二氢喹啉。通常用于帮助缩合的碱是无机碱如碳酸钠或碳酸钾,或有机碱如吡啶、三乙胺、N,N-二异丙基乙胺或4-(二甲基氨基)吡啶。
可选地,本发明中式I化合物的制备可以采用如以上(对于方案1)描述的类似缩合方法,通过式IV化合物与式V化合物反应而进行(方案2),;其中R1、R2、R3和L如先前所定义的。

方案3
用类似的方式,可通过肼水合物化合物和式V的反应制备式III化合物(方案4)。
方案4
可按照文献中已知的方法制备式II化合物。方案5中提供了合适的制备式II化合物的方法。
方案5
如方案5中举例说明的,式VIII的吡啶的乙炔基部分偶联式IX的苯基环,或式VII的苯基环的乙炔基部分偶联式VI的吡啶环;其中‘W’代表像OTf、Cl、Br或I的离去基团,优选地代表Br或I;L代表OH或O-烷基。可以通过使用众所周知的现有技术方法实施偶联反应,如金属催化偶联反应,例如钯催化Sonogashira偶联反应(参考Malleron,J-L.,Fiaud,J-C.,Legros,J-Y.Handbook of Palladium Catalyzed Organic Reactions,San Diego:Academic Press,1997)。可选地,从式IIa邻近的二卤化合物(其中Z代表卤素)通过串联的脱氢卤化作用来制备式II化合物。
以上相似的策略可用于合成式I化合物,如方案6所示,即,将式VIII的吡啶环的乙炔基部分偶联到式XI的苯基环上,或将式X的苯基环的乙炔基部分偶联到式VI的吡啶环;其中W、R1、R2和R3如先前所定义的。
方案6
可以通过式III的酰肼分别与式VII化合物和式IX化合物的酰化作用便利地制备式X化合物和式XI化合物,如方案7中所示;其中L、W、X、R1、R2和R3如先前所定义的。
方案7
还可以通过式XII的胺的酰化作用制备式I化合物,如方案8所示。
方案8
其中以上起始化合物VI、VII、VIII和IX包含可能干扰偶联反应的官能团,该官能团采用后期可方便移除的合适的保护基团进行保护。
