Abstract
通式(I)的二氮杂䓬并吲哚衍生物、它们的外消旋体、它们的对映体和它们的可药用盐在制备能够治疗与采用磷酸二酯酶IV抑制剂的治疗有关的疾病的药剂方面的应用,其中:-R是氢、低级烷基或低级烷氧基;-A是一-到三取代的杂芳基或芳基。
Description
本发明涉及[1,4]二氮杂并[6,7,1-hi]吲哚的用途,其中一部分是新的,用于制备能够治疗与采用磷酸二酯酶IV抑制剂的治疗法有关的疾病的药剂。这些药剂尤其适用作消炎药、抗过敏药、支气管扩张剂或者止喘药,并且对消化系统或心脏没有副作用。
与本发明公开的性质相反,现有技术推荐了[1,4]二氮杂并[6,7,1-hi]吲哚,其中描述了相对于缩胆囊肽(CCK)和/或促胃酸激素的拮抗性,并被推荐用于消化系统胃、肠、胰和胆囊的疾病,并特别用于饱涨疾病。
欧洲专利申请No340064记载了通式如下的化合物:
其中R1和R2是氢或卤,Ar是吲哚基或苯基,n是2或3。这些化合物是外部缩胆囊肽拮抗剂(CCKA)。
欧洲专利申请No360079记载了外部和/或中心CCK-拮抗化合物,其通式为:其中R1是视具体情况而定被取代的芳基、X是氧或选择性被低级烷基取代的亚甲基,A是一个键或可以带有一个或多个低级烷基的低级亚烷基,R2是氢或非常广义上的酰基。实际上它表明申请EP360079的优选产物是其中基团如下定义的物质:
-R1是2-氟苯基和/或
-R2是芳基-丙烯酰基或者杂芳基-丙烯酰基,和/或
-其羰基的α位二氮杂碳的构象是(S)或(R,S)。
至于磷酸二酯酶的抑制性,使人想起3’,5’-环腺苷酸(cAMP)是通用的次级细胞内信使,在初级信使(激素、神经递质、内分泌物)和细胞功能响应之间的中间体:初级信使依靠所指的细胞激发负责合成cAMP的酶且cAMP具有许多功能:代谢作用、收缩性或者分泌性。当其被环核苷酸磷酸二酯酶分解时,cAMP的作用就结束,环核苷酸磷酸二酯酶是催化其水解成稳定的5’-环腺苷酸的胞内酶。
哺乳动物中,在根据其结构、其动力学特性、其酶解物特异性或者其对效应物的敏感性分为I到V的环核苷酸磷酸二酯酶(PDEs)的至少五大类之间存在区别(Beavo J.A.(1990) Trends Pharmacol.Sci.11,150-155)。PDEs IV对于cAMP有特效。
非特异性磷酸二酯酶抑制剂化合物已知能够抑制几类酶。对于一些甲基黄嘌呤,如茶碱来说是这样的。这些化合物具体地由其对存在于细胞中而不是靶细胞中的PDE类的作用而使其治疗指数低。相反,一些种类的PDE可以被多种药剂选择性地抑制:减慢环核苷酸的水解,并因此而提高它们只在那些含有对抑制剂敏感的这类PDE的细胞中的浓度。
磷酸二酯酶IV(PDEs IV)显得特别有利,这在许多包括中枢神经系统、心脏、血管内皮、血管平滑肌和气管和骨髓和淋巴管的组织中已被证明。
在发炎细胞中增加cAMP会抑制其活性:抑制含一定浓度肥大细胞、单核细胞、嗜酸性细胞和嗜碱性多形核白细胞介质的合成和释放,抑制中性白细胞和嗜酸性多形核白细胞的趋化性和脱粒,抑制淋巴细胞的分裂和分化。
由不同类型白细胞产生的细胞因子,尤其是TNF和白介素,例如T淋巴细胞和嗜酸性多形核白细胞在炎症表现的初期,特别是在由呼吸道上的过敏原产生的刺激的反应方面起主要作用。
另一方面,cAMP减少了气道的平滑肌纤维的紧张程度;PDE IV抑制剂引起支气管舒张。
因此可以预计选择性PDE IV抑制剂具有作为消炎药、抗过敏药和支气管扩张剂以及用于治疗其由发炎细胞浸润了气道造成的哮喘的治疗活性并可用于支气管狭窄。
茶碱在很长时间里广泛用于治疗哮喘,并且尽管其作用机理复杂,但PDE的抑制不仅有助于其活性,而且会产生些不良副作用,如恶心和头痛。
但是,强PDE IV抑制剂的开发由于许多可能的PDE IV抑制剂对其它种类的磷酸二酯酶具有活性至今已被证明是困难的。
因此PDE IV抑制剂缺乏选择性产生了一个由cAMP调节的功能程度的问题。这就需要强的具有选择性的PDE IV抑制剂,就是说对属于其它种类的PDEs没有活性。最初在1975年合成的吡咯烷酮衍生物环戊氧基甲基苯基吡咯烷酮(INN)被认为是代表了特效PDE IV抑制剂。与环戊氧基甲基苯基吡咯烷酮有关的大量化合物是在考虑到其作为PDE IV抑制剂的用途而合成的。在活体外,环戊氧基甲基苯基吡咯烷酮抑制了啮齿动物体内发炎细胞的活性:抑制由肥大细胞、嗜酸粒细胞和嗜碱性多形核白细胞、单核细胞进行的介质合成;抑制多形核白细胞的趋化性和脱粒。已建议将环戊氧基甲基苯基吡咯烷酮用作抗抑郁药;但是其用途伴随包括恶心和呕吐类型的不良副作用。
与现有技术不同的是,业已发现其中一些是新的[1,4]二氮杂并[6,7,1-hi]吲哚衍生物在其对其它种类的PDE具有很小或没有活性的浓度下是出乎意料的强的PDE IV抑制剂。
本发明主要涉及其中部分是新的通式为(I)的二氮杂并吲哚的用途:其中:-R是氢、低级烷基或低级烷氧基,和-A是芳基,含氮杂芳基或者含硫杂芳基,其中每个被一个到三个分别选自:卤、低级烷基、卤代烷基、低级烷氧基、羟基、乙酰氧基、氨基、叔丁氧基羰基氨基、环烷基羰基氨基和乙酰氨基的基团选择性取代。
首先,本发明涉及通式为(I)的二氮杂并吲哚的用途,用于制备能够治疗与由磷酸二酯酶IV抑制剂的治疗法有关的疾病的药剂:其中:-R是氢、低级烷基或低级烷氧基,和-A是芳基,含氮杂芳基或者含硫杂芳基,它们均被一个到三个分别选自:卤、低级烷基、卤代烷基、低级烷氧基、羟基、乙酰氧基、氨基、叔丁氧基羰基氨基、环烷基羰基氨基和乙酰氨基的基团选择性取代;涉及它们的外消旋体、其结构由在二氮杂并吲哚-4-酮环系统的3位的碳确定的异构体,以及它们的可药用盐。
再者,本发明涉及通式为(I’)的二氮杂并吲哚:其中:-R是氢、低级烷基或低级烷氧基,和-A是芳基,含氮杂芳基或者含硫杂芳基,它们均被一个到三个分别选自:卤、低级烷基、卤代烷基、低级烷氧基、羟基、乙酰氧基、氨基、叔丁氧基羰基氨基、环烷基羰基氨基和乙酰氨基的基团选择性取代;涉及它们的外消旋体、它们的其结构由在二氮杂鉯并吲哚-4-酮环系统的3位碳确定的异构体,以及它们的可药用盐,条件是当R是氢时:i)A不表示被一个到三个烷氧基取代的2-吲哚基或者苯基;ii)对于外消旋体或者(S)构象形式来说,A不表示一个被卤、一个卤和一个氨基或者卤代烷基取代的苯基。
在上文和下文中:-芳基是指苯基或者萘基;-含氮杂芳基是指含有至少一个氮原子的不饱和单环或多环基团,并优选其中含氮杂环可以是含有1-4个氮原子的4-7元杂单环基团,或者不饱和含有1-4个氮原子的缩合杂环基团;含氮杂芳基可以是在带正电氮上被甲基化或乙基化;-卤是指氟、氯、溴或碘;-低级烷基是指含有1-4个碳原子的直链或支链烷基;环烷基是指环丙基、环丁基和环戊基;-低级烷氧基是指O-烷基,其中烷基是如上所述的低级烷基;和-卤代烷基是指含有1-4个碳原子的单-、二-或者三卤代烷基。
关于可药用盐的研究记载在J.Pharm.Sci,.1977,
66,1-19中。但是,含有碱部分的通式(I)化合物的可药用盐是指由无机或者有机的、无毒酸,例如氢溴酸、氢氯酸、硫酸、氨基磺酸、磷酸、硝酸、乙酸、丙酸、丁二酸、乙醇酸、硬脂酸、乳酸、苹果酸,酒石酸、柠檬酸、粘酸、抗坏血酸、双羟萘酸、马来酸、羟基马来酸、苯基乙酸、谷氨酸、苯甲酸、水杨酸、磺胺酸、乙酸基苯甲酸、延胡索酸、苯甲磺酸、乙烷二磺酸、酸、羟乙磺酸和其它酸制成的通式(I)化合物的加成盐。衍生物(I)的各种季铵盐也属于本发明化合物。含有酸部分的通式(I)化合物的可药用盐是指通式(I)化合物的常规盐,是由无机或有机、无毒碱制成,例如碱金属和碱土金属氢氧化物(锂、钠、钾、镁和钙)、胺(二苄基亚乙基二胺、三甲基胺、哌啶、吡咯烷酮、苄基胺等等)或者选择性的氢氧化季铵,如氢氧化四甲铵。

本发明的通式(I)化合物抑制环核苷酸磷酸二酯酶的性能是通过测定它们的IC50(抑制50%酶催活性所需的浓度)来评估。对于PDEs IV来说,通过环戊氧基甲基苯基吡咯烷酮的IC50与要测试产物的IC50的比值来将此值和环戊氧基甲基苯基吡咯烷酮的IC50,即与同一酶的制备有关的PDE IV的特定抑制剂进行比较。
磷酸二酯酶的不同种类是以在DEAE-纤维素柱中由豚鼠气管和狗的主动脉根据W.J.Thompson et al.,1979,Advances in Cyclis NucleotideResearch,Vol.10:69-92,ed.G.Brooker et al.,Raven Press,New Yorl,and ofP.J.Silver et al.,1988,Eur.J.Pharmacol.150:85-94相应的方法以部分纯化的形式得到。
因此,不同种类PDE,特别是PDEs IV的酶催活性的测定是根据与W.J.Thompson,ibidem所用方法类似的方法进行。
为了测定IC50,在有浓度在0.1到100μM范围内的抑制剂存在情况下测定酶催活性。
下面表格说明与由豚鼠气管获得的酶制剂的环戊氧基甲基苯基吡咯烷酮的活性相比的PDE IV抑制剂的活性。

对上面表格的研究表明进行研究的本发明产物通常比环戊氧基甲基苯基吡咯烷酮能更有效地抑制来自豚鼠气管的PDE IV酶,并且在许多情况下具有比环戊氧基甲基苯基吡咯烷酮多两倍到三倍的活性。
而且,对从豚鼠气管或者狗的主动脉纯化而来的不同种类PDEs进行的研究表明由涉及第III类和第I和V类的本发明产物获得的IC50值远高于由第IV类PDEs测定的值。
这些结果是本发明产物与PDEs IV有关的强的和选择性抑制活性的有利证明。-体内抗炎症和抗过敏活性
本发明产物的效果在豚鼠中以根据由Lagente V.et al.(1994)Br.J.Pharmacol.
112,83P描述的通过抗原激发或通过暴露于PAF汽溶胶引起的嗜酸性细胞渗透性模型中进行研究。
采用实施例的产物(1-30mg/kg p.o.)大大减少了在支气管肺泡清洗液中的嗜酸性细胞的数量。
采用本发明的产物还减少了由在豚鼠的IL-5气管内滴入法引起的发炎反应。-抑制细胞因子分泌
本发明产物对由人的单核白细胞产生的细胞因子分泌的活性是按照由Konno S.et al.(1994)Eur.J.Pharmacol.264:265-268和Endo H.et al(1993)Int.Arch.Allergy Immunol.101:425-430 for interleukins,and bysemmler J.et al.(1993)Int.J.Immunopharmac.15:409-413 and VergheseM.W.et al.(1995)J.Pharmacol.Exp.Ther.272:1313-1320for TNFα描述的方法在体外进行测定的。采用interleukinsIL-2、IL-4和IL-5以及采用TNFα是通过免疫酶方法进行的。计算抑制50%的伴刀豆球蛋白A、植物血球凝集素或者脂多糖类激发的细胞因子的产生的IC50浓度值。
在这些条件下,被试验证明具有显著抑制活性的本发明产物(I)具有通常小于或者等于10-5摩尔/升的IC50值。-毒理性
实施例2.V的亚急性口腔毒性是对大鼠进行研究的。当以100mg/kg/day的剂量采用1%在甲基纤维素中的水的悬浮液用药两周情况下,此产物表明没有与毒性有关的活性。
特别是在狗体内证明没有催吐效果。实施例4和9.B产物以3mg/kg的剂量静脉注射时表明没有催吐效果。
这些结果证明本发明的产物具有抗炎症和/或免疫抑制活性。因此本发明的产物适特别适用于治疗或防治:
-过敏病变,特别是哮喘和变应性皮炎;
-炎症病变,特别是支气管区的,以及风湿性关节炎、肠道炎症(出血性直肠结肠炎和节段性回肠炎);
包括自身免疫成分的情况。药理部分
