Description
技术领域
本发明涉及作为钾通道抑制剂的噻吩并嘧啶化合物。本发明也提供了包含所述化合物的药物组合物和它们在治疗心律失常中的用途。
背景技术
离子通道是跨越细胞膜脂双层的蛋白质,它们提供了含水通路,通过该含水通路,特定的离子诸如Na+、K+、Ca2+和Cl-能够穿过(Herbert,1998)。钾通道是离子通道中最庞大且最多样化的亚组,它们在调节膜电位和控制细胞兴奋性(cellularexcitability)中发挥首要的作用(Armstrong&Hille,1998)。根据钾通道的氨基酸序列和它们的生物物理学特性,钾通道已经被分类成多个基因家族(对各个基因家族的命名,参见Gutman et al.,2003)。
调节钾通道的化合物在若干疾病领域具有多种治疗应用,这些疾病包括心血管疾病、神经疾病、听觉疾病、肾脏疾病、代谢疾病和细胞增殖性疾病(Shieh et al.,2000;Ford et al.,2002)。更具体地,钾通道诸如Kv4.3、Kir2.1、hERG、KCNQ1/minK和Kv1.5与心脏肌细胞动作电位的复极化相(repolarisation phase)密切相关。这些钾通道亚型与心血管疾病和障碍有关,心血管疾病和障碍包括QT间期延长综合症(long QT syndrome)、肥大症、心室纤维性颤动和心房纤维性颤动,所有这些心血管疾病和障碍都会引起心脏衰竭和死亡(Marban,2002)。
人的延迟整流电压门控钾通道亚基(human delayed rectifier voltage gatedpotassium channel subunit)Kv1.5,专门在心房肌细胞中表达,并被认为为控制心房纤维性颤动提供了治疗机会(参见Brendel and Peukert,2002的综述),理由有若干:(i)有证据表明,基于类似的生物物理学和药理学特性,发现Kv1.5是人心脏超速延时整流(Kv(ur))生理电流的基础(Wang et al.,1993;和Fedida et al.,1993)。这已经得到Kv1.5的反义寡核苷酸的支持,已经表明Kv1.5的反义寡核苷酸可以降低人心房肌细胞的Kv(ur)幅度(Feng et al.,1997);(ii)电生理学记录已经显示,Kv(ur) 选择性地出现在心房肌细胞中,因此通过干扰心室复极化,可避免诱导潜在致命的心室心率失常(Amos et al.,1996;Li et al.,1996;和Nattel,2002);(iii)相比起正常健康人的心房肌细胞,抑制心房纤颤型人心房肌细胞中的Kv(ur)可延长动作电位时程(Courtemanche et al.,1999);(iv)相比起传统的III类抗心律失常药,通过延长心房不应期而保持心室不应性不变,选择性地抑制Kv1.5来延长动作电位时程可 以提供更为安全的药理学干扰作用,从而预防心房折返型心律失常,诸如心房纤颤和心房扑动(Nattel et al.,1999,Knobloch et al.,2002;和Wirth et al.,2003)。已经广泛报道,III类抗心律失常药是治疗心脏心律失常的优选方法(Colatsky et al.,1990)。
已经报道,传统的和新型的III类抗心律失常钾通道阻断剂(blocker)具有直接调节Kv1.5或Kv(ur)的作用机理。已经报道,已知的III类抗心律失常药:氨巴利特(Feng et al.,1997)、奎尼丁(Wang et al.,1995)、氯非铵(Malayev et al.,1995)和柏托沙米(Godreau et al.,2002)都是人心房肌细胞Kv(ur)的钾通道阻断剂。新型的苯并吡喃衍生物NIP-142,在犬体内模型中,封阻Kv1.5通道,延长心房不应期,并终止心房纤颤和扑动(Matsuda et al.,2001);S9947抑制Kv1.5在蟾蜍卵母细胞和中国仓鼠卵巢(CHO)细胞中的稳定表达,S9947也抑制在土生鼠和人心脏肌细胞中的Kv(ur)(Bachmann et al.,2001)。此外,已经描述了靶向Kv1.5或Kv(ur)的其他新型钾通道调节剂在治疗心脏心律失常中的应用,这些调节剂包括联苯类化合物(Peukert et al 2003);噻吩羧酸酰胺类化合物(WO0248131);双芳基衍生物(WO0244137,WO0246162);碳酰胺衍生物(WO0100573,WO0125189);邻氨基苯甲酸酰胺类化合物(WO2002100825,WO02088073,WO02087568);二氢嘧啶类化合物(WO0140231);环烷基衍生物(WO03063797);茚满衍生物(WO0146155,WO9804521);萘满苯并环庚烷衍生物(WO9937607);噻唑烷酮和间噻嗪烷酮(metathiazanone)衍生物(WO9962891);苯甲酰胺衍生物(WO0025774);异喹啉衍生物(WO0224655);哒嗪酮衍生物(WO9818475,WO9818476);色满衍生物(WO9804542);苯并吡喃衍生物(WO0121610,WO03000675,WO0121609,WO0125224,WO02064581);苯并噁嗪衍生物(WO0012492),以及从海洋物质中纯化得到的新型化合物A1998(Xu&Xu,2000)。
已经报道,噻吩并嘧啶可以与其他药剂一起用作抗炎症、抗真菌、抗骨质疏松和抗微生物药剂。尽管也已经报道噻吩并嘧啶是心血管药剂(通过调节磷酸二酯酶类酶或通过调节钠/质子交换系统来起作用),但之前还没有报道过噻吩并嘧啶是调节离子通道的有用药剂。
在4-位置用任选地取代的苄胺或苯乙胺部分(moiety)取代的、在5-位置用甲基基团取代的噻吩并[2,3-d]-嘧啶可以用作抗炎症或抗骨质疏松剂(Katada et al.,1999)。此类化合物显示能够调节若干细胞类型的活性,包括由骨髓中的造血祖细胞产生的白细胞。白细胞活性的增加能够导致产生各种炎症性疾病;因此对白细胞具有细胞毒性的化合物能够发挥抗炎症药物的功能。此类化合物被认为是通过结合到白细胞表面上的整联蛋白,并阻断下游细胞信号传导来抑制细胞活性。在 4-位置用杂芳基硫醇、芳基硫醇、芳基甲基硫醇、杂芳胺、苄胺、羟基和氯基团取代的噻吩并[2,3-d]嘧啶也可以用作抗炎药(Stewart et al.,2001)。该系列的化合物显示出能够抑制细胞粘附分子在血管内皮腔表面上的诱导型表达,因而阻止白细胞在炎症位置的粘附。
下列物质都已表明具有抗微生物活性:在4-位置上带有取代的肼并在5位置带有苯基基团的噻吩并[2,3-d]嘧啶(Hozien et al.,1996);四氢苯并[b]噻吩并[2,3-d]嘧啶(Ismail et al.,1995);在2-位置上带有氢、氯、肼、杂环、氨基、甲基、乙基或苯基基团,在4-位置上带有烷基氨基、烷芳基氨基、氨基、二烷基氨基或肼取代基,在5-位置上带有氢或甲基基团,在6-位置上带有氢、甲基乙酰胺或苯基基团,或在5,6-位置上带有四亚甲基的噻吩并[2,3-d]嘧啶(GB7549025);在2-位置上带有甲基或苯基,在4-位置上带有烷基氨基或芳基氨基的一系列5-苯基-和5,6-四亚甲基噻吩并[2,3-d]嘧啶(Konno et al.,1989)。在4-位置上带有2-氧代-3-吡咯烷基亚甲基-肼部分的四氢苯并噻吩并[2,3-d]嘧啶对绒叶(velvet leaf)显示出一些除草活性(Ram et al.,1981)。也已报道,4-氯四氢苯并噻吩并[2,3-d]嘧啶具有除草性;在4-位置带有硫醇、肼、2-氟苯胺、3-氟苯胺或4-二乙苯胺取代基的四氢苯并噻吩并-[2,3-d]嘧啶对粪便链球菌(Streptococcus fecales)具有杀菌性;在4-位置带有2,4-二氯苄基氨基或2-氟苯胺取代基的四氢苯并噻吩并[2,3-d]嘧啶对腐霉菌(Pythium)具有杀真菌特性(Ram,1979)。已经报道,在2-位置带有氢、羟基、硫醇、卤素或氰基,在4-位置带有烷基氨基、芳基烷基氨基或羟基烷基氨基基团,在5-和/或6-位置带有氢、烷基或卤素,或在5,6-位置带有亚烷基的噻吩并[2,3-d]嘧啶是蜱抑制剂(tick-control agents)(AU 521790)。
此外,四氢苯并[b]噻吩并[2,3-d]嘧啶显示出抗肿瘤活性(Shehata et al.,1996)和阿司匹林一半的止痛活性(Moneer et al.,1994);一系列带有4-烷基氨基或芳基氨基、5-H或5-甲基、6-甲基或5,6-四亚甲基的噻吩并[2,3-d]嘧啶显示具有抗细胞分裂素的潜能(Jordis et al.,1986);一系列的5,6-二甲基-噻吩并[2,3-d]嘧啶和5,6-四亚甲基噻吩并[2,3-d]嘧啶——两者都在2-位置用芳胺或杂环胺取代并在4-位置用芳胺取代——显示出血小板凝集抑制特性(DD 226893);4-位置用氨基、丁胺、苯胺、环己胺、苄胺、苯乙胺和2-羟乙胺取代的吡喃并-和噻喃并[3,4-b]噻吩并[5,4-d]嘧啶据报道具有抗痉挛活性(Noravyan et al.,1977);4-[(苯并-2,1,3-噻二唑-4)氨基]-5,6,7,8-四氢苯并噻吩并-(2,3-d)-嘧啶据报道在幼虫泡球蚴病(larval alveolarechinococcosis)中具有驱虫活性(RU 2116309)。
在4-位置上带有取代的氨基基团,在5和6-位置上带有氢、烷基或卤素取代基,和在2-位置带有烷基链的噻吩并[2,3-d]嘧啶据说是磷酸二酯酶V的抑制剂, 并可以用于治疗心血管疾病和效能障碍(disturbances in potency)(DE10104802)。
此外,发现在4-位置上具有哌嗪取代基的5-烷基噻吩并[2,3-d]嘧啶是钠/质子交换蛋白(sodium/proton exchanger)的抑制剂,并可以用于治疗各种心血管病症,包括心绞痛和心律失常(WO 01/27107)。
已经发现,带有5-苯硫基取代基和2-甲基取代基的4-[(苯基)氨基]-噻吩并[2,3-d]嘧啶具有杀软体动物活性(Hosni et al,Acta Poloniae Pharmaceutica,1999,56(1),49-56)。
最近已经报道,噻吩并嘧啶是强效VEGFR抑制剂(Munch hof,2004)。
若干公开出版物公开了可作用于钾通道的化合物。对此,US6531495公开了2′-氨基甲基联苯基-2-甲酰胺,WO2002/100825公开了邻氨基苯甲酸酰胺作为抗心律失常剂,WO2002/036556公开了酰基氨基烷基苯磺酰胺(acylaminoalkylbenzenesulfonamides)作为心血管药剂。

钾通道的孔对其他单价阳离子诸如Rb+和Tl+具有可透性。通过对钾通道可透性离子的细胞流量进行的分析,能够直接监控钾通道活性。将用人Kv1.5的cDNA(已插入到pEF6::VA-His-TOPO中)稳定转染的细胞培养在DMEM培养基(Dulbecco’s Modified Eagle media(DMEM))α中,该培养基补充有10%胎牛血清(FCS)、20μl/ml青霉素(5000U/ml)、链霉素(5000μg/ml)、10μl/ml[100×]谷氨酰胺和杀稻瘟素(blasticidin)(7.5μg/ml)。将细胞分配到96孔Cellstar TC板中,让细胞生长,直到看见汇合的单层。在一轮测定的开始时,冷的培养基用TECAN洗板机吸走,使用Shallow-Well Matrix Platemate,将含有2μtCi/ml(37kBq/ml)86Rb+的50μl培养基(media spike)加入到含有细胞的每一个孔中。在37℃,将板放置于温育箱中最少3个小时。吸走“热”培养基中未加载的86Rb+,每一个孔用4×250μl的Earls Balanced Salt Solution(EBSS)洗涤,EBSS含有5mM KCl、140mM NaCl、2mM CaCl2、1mM MgSO4、10mM HEPES和5mM葡萄糖,pH 7.4,290-300mOsm。然后,在室温中,用50μl的EBSS+/-测试化合物预温育这些细胞10分钟。温育10分钟之后,加入50μl的改性EBSS,改性EBSS含有145mM KCl、2mM CaCl2、1mM MgSO4、10mM HEPES、5mM葡萄糖,pH 7.4,290-300mOsm,然后在室温中再温育这些细胞10分钟。用高KCl的EBSS将细胞去极化至膜电位,该电位将激活Kv1.5通道。最终的温育之后,将80μl/100μl的反应物从每一个孔转移到Packard“Optiplate”白96孔板中的对应孔内,并利用Cerenkov发射在PackardTopCount液体闪烁计数器中计数。采用2.5mM的4氨基-吡啶对Kv1.5的对照阻断作用作为校准基准,计算出通过Kv1.5的86Rb+流量的抑制百分比。可替代地,细胞装载85Rb+,并通过原子吸收光谱法进行定量。使用上述方法,由10个点的浓度响应曲线n=2(10point concentration response curves n=2)测定出IC50。使用 Graphpad Prism(V3.02)软件,数据按照变量斜率S形曲线拟合(variable slopesigmoidal fit)来进行拟合。

Kv1.5 Autopatch电生理学方法(Autopatch Electrophysiology Method)
外部浴液(bather solution)含有(mM):150NaCl、10KCl、100葡萄糖酸钾、3MgCl2、1CaCl2、10HEPES,pH 7.4。膜片吸管(Patch pipettes)充满电极溶液,其组成为(mM):160KCl、0.5MgCl2、10HEPES、1EGTA,pH 7.4,用KOH调节。
将化合物溶解在DMSO(100%)中,在外部浴槽(external bather)中配置成1μM的浓度。所有实验在室温(22-24℃)中进行。
在使用之前约1小时,将密度为100,000个细胞/ml的细胞悬浮液(10ml)等份装入15ml离心管中,并转移到培养箱(37℃,5%CO2)中。温育60分钟之后,取出离心管,在室温中,以1000rpm的转速离心4分钟。弃掉9.5ml的上清夜,在管底留有细胞沉淀。然后用100μl冷的(4℃)、过滤的(0.22μm)、0.2%的BSA/浴液(0.02g BSA/10ml浴液)重新悬浮该细胞沉淀。手动温和搅拌管底,直到溶液与细胞混和。然后,将100μl细胞重悬浮溶液保存在工作台上,温度为4℃(使用基于珀尔帖(Peltier)的温度控制装置),直到使用。
将一定长度的毛细管玻璃(1B150F-4,WPI)浸在细胞悬浮液中,这样,通过毛细管作用吸上~3cm体积的液体。将Ag/AgCl金属丝伸入毛细管的未浸端中。将毛细管充满溶液一端的外部进行干燥,并将毛细管装载入AutoPatchTM。使用DMZ吸管拉伸器(Zeitz Instruments)牵拉硼硅酸盐玻璃膜片吸管(来自1.Smm OD,薄壁丝化GC150-TF毛细管玻璃,Harvard),用内部吸管溶液回填,小心不要将气泡留在吸管尖端或管内。膜片吸管通常具有2.3-3.5MΩ的电阻。充满之后,将吸管尖端和一部分的管身(~15mm)浸入Sigmacote(Sigma)中。然后将记录吸管(recordingpipette)装入AutoPatchTM。由操作员启动自动化膜片钳,如果预设的条件和标准令人满意的话,随后由AutoPatch.exe继续进行实验操作。
全细胞膜片钳记录在室温(22-24℃)中使用AutoPatchTM设备获得,AutoPatchTM 设备整合有:由脉冲软件(Pulse software)(v8.54,HEKA,Germany)控制的EPC9放大器(HEKA,Germany)、具有2个翻译器的运动控制器(Newport,UK)、阀控制器(VFl)和c-级抽吸装置(c-level suction device)。该设备完全在AutoPatch-exe控制下进行,仅当需要对药剂容器进行再充满时,或防止由于技术故障引起的细胞损失时,才需要操作人员介入。Rseries大于18MΩ的细胞从实验中扣除。
在灌输和药物应用之前,质量鉴定步骤确保被观测的电流满足实验标准。只有IK>500pA的那些细胞才可以用于实验。细胞持续用外部溶液以1.8-2ml/分钟的流速进行灌注。灌注室的工作容量为80-85μl,并允许药物溶液的快速交换。借助于AutoPatchTM软件,在应用化合物期间,对hKv1.5电流进行在线分析。按常规电生理学中描述的方法,实施电压阶方案(Voltage-step protocols)和数据分析。
电生理学电压阶方案和数据分析按下述方法进行:数据在5kHz时被取样,并以2.5kHz的-3dB带宽滤过。细胞保持在电压-80mV。每5秒0mV,将电流激发至持续时间为1000ms的电压阶跃。电流用Pulsefit software(v8.54,HEKA,Germany)分析,在整个电压阶跃期间测量总荷。所有其它的图都用Igor Pro(WaveMetrics)产生。
