发明领域
本发明涉及调节和/或抑制某些蛋白激酶活性的二氨基噻唑化合物,和含有这些化合物的药物组合物。本发明还涉及这些化合物和组合物的治疗或预防用法,还涉及通过给予有效量的这些化合物来治疗癌症以及其他与不良的血管生成和/或细胞增生相关的疾病的方法。
发明背景
蛋白激酶是一类催化蛋白质中特定的酪氨酸、丝氨酸或苏氨酸残基的羟基基团磷酸化的酶。典型地,这种磷酸化剧烈地于扰蛋白质的功能,并因此蛋白激酶在调节各种细胞过程(包括代谢、细胞增生、细胞分化和细胞存活)中起关键作用。在许多不同的已知需要蛋白激酶活性的细胞功能中,一些过程表现为治疗性干涉某些疾病的引入注意的靶位。两个实例为血管生成和细胞循环控制,其中蛋白激酶起关键作用,这些过程对实体瘤的生长和其他疾病而言是必需的。
血管生成是一种由已存在的血管形成新的毛细血管的机制。需要时,脉管系统能生成新的毛细血管网,以维持组织和器官的适当功能。然而对成年人而言,血管生成是被适当限制的,仅在伤口愈合和月经期子宫内膜的新血管生成时才发生。参见Merenmies等人,“细胞的生长和分化”,8,3-10(1997)。另一方面,不良的血管生成是一些疾病的标志,如视网膜病、牛皮癣、类风湿关节炎、与年龄相关的黄斑部变性(AMD)和癌症(实体瘤)。Folkman,Nature Med.,1,27-31(1995)。已显示参与血管生成过程的蛋白激酶包括生长因子受体酪氨酸激酶家族的三类成员:VEGF-R2(血管内皮生长因子受体2,也称为KDR(激酶插入区域受体)和FLK-1)、FGF-R(成纤维母细胞生长因子受体)和TEK(也称为Tie-2)。
VEGF-R2(仅在内皮细胞上表达)与有效的血管生成生长因子VEGF结合,并通过活化它的细胞内的激酶活性调节随后的信号转导。所以,预计直接抑制VEGF-R2的激酶活性,即使存在外源性VEGF也能降低血管生成(参见Strawn等人,“癌症研究”,56,3540-3545(1996)),这已由不能调节信号转导的VEGF-R2的突变体所表明。Millauer等人,“癌症研究”,56,1615-1620(1996)。另外,VEGF-R2除调节VEGF的血管生成活性外对成年人没有其他功能。所以,预计VEGF-R2激酶活性的选择性抑制剂可由表现出极小的毒性。
类似地,FGF-R与血管生成生长因子aFGF和bFGF结合,并调节随后的细胞内的信号转导。最近,已有建议认为生长因子如bFGF可能在诱发已生长到一定大小的实体瘤的血管生成中起决定性作用。Yoshiji等人,“癌症研究”,57,3924-3928(1997)。但是,与VEGF-R2不同,FGF-R在全身许多不同类型的细胞中表达,而且在成年人的其他正常生理过程中可能或可能不起重要作用。尽管如此,已报道了全身给予FGF-R激酶活性的小分子抑制剂能封阻小鼠中的bFGF诱导的血管生成,而无明显的毒性。Mohammadi等人,EMBO Journal,17,5896-5904(1998)。
TEK(也称为Tie-2)是另一种仅在内皮细胞上表达的受体酪氨酸激酶,其已显示出在血管生成中起作用。血管形成因子(angiopoietin)-1的结合使TEK的激酶区域自身磷酸化,并导致可能调节内皮细胞与内皮周围支持细胞的相互作用,从而有利于新形成的血管的成熟的信号转导过程。另一方面,血管形成因子-2表现为对抗血管形成因子-1对TEK的作用并破坏血管形成。Maisonpierre等人,Science,277,55-60(1997)。
作为上述研究的结果,已有人建议用抑制VEGF-R2、FGF-R和/或TEK的激酶活性的化合物来治疗血管生成病。例如,WIPO国际出版物No.WO97/34876公开了作为VEGF-R2抑制剂的某些噌啉衍生物,可用于治疗与异常血管生成和/或血管渗透性增加相关的疾病,如癌症、糖尿病、牛皮癣、类风湿性关节炎、卡波西肉瘤、血管瘤、急性和慢性肾病、粉瘤、动脉再狭窄(restinosis)、自身免疫性疾病、急性炎症和视网膜脉管增生的眼病。
除了在血管形成中起作用外,蛋白激酶还在细胞循环的控制中起重要作用。细胞增生的失控是癌症的标志。应答各种刺激的细胞增生表现为细胞分裂周期(细胞通过该过程增殖和分裂)的解调控。肿瘤细胞对直接或间接调控通过细胞分裂循环的过程的基因通常有破坏作用。
细胞周期调节蛋白依赖性激酶(CDK)是丝氨酸-苏氨酸蛋白激酶,在调节细胞周期的不同期之间的过渡中起重要作用。参见Science中所编写的文献,274,1643-1677(1996)。通过调节性细胞周期蛋白亚基(如细胞周期调节蛋白A、B1、B2、D1、D2、D3和E)与催化性激酶亚基(如cdc2(CDK1)、CDK2、CDK4、CDK5和CDK6)的缔合形成CDK复合物。就如名称所示的,CDK绝对依赖于细胞周期调节蛋白亚基来磷酸化它们的靶标底物,且不同的激酶/细胞周期调节蛋白对通过细胞周期的特定的期起调节进程的作用。
在引发细胞分裂周期从休眠或静止阶段转化成细胞要发生细胞分裂的阶段中起关键作用的是与D细胞周期调节蛋白复合的CDK4。这一进程受到各种生长调节机制负的或正的作用。这种控制系统中的畸变,尤其是那些影响CDK4功能的畸变,已认为涉及细胞发展至以恶性为特征的高度增生的状态,尤其是家族性黑色素瘤、食管癌和胰腺癌。参见Kamb,Trends in Genetics,11,136-140(1995);Kamb等人,Science,264,436-440(1994)。
将化合物用作抑制CDK的抗增生治疗剂是一些专利出版物的主题。例如,Xiong等人的美国专利No.5,621,082公开了编码CDK6抑制剂的核酸,和欧洲专利出版物No.0666 270 A2描述了作为CDK1和CDK2抑制剂的肽和肽模拟物。WIPO国际出版物No.WO 97/16447公开了某些色酮模拟物,它们是细胞周期调节蛋白依赖性激酶的抑制剂,尤其是CDK/细胞周期调节蛋白复合物如CDK4/细胞周期调节蛋白D1的抑制剂,可用于抑制过量或异常细胞增生,从而用来治疗癌症。WIPO国际出版物No.WO99/21845公开了可用作CDK抑制剂的4-氨基噻唑衍生物。
但是,依旧需要易合成且能有效抑制一种或多种CDK或CDK/细胞周期调节蛋白复合物的小分子化合物。因为CDK4可作为大多数细胞中细胞分裂的通用活化剂,且CDK4和D类型细胞周期调节蛋白的复合物控制细胞周期的早期G1期,所以需要CDK4及其与D类型细胞周期调节蛋白复合物的有效抑制剂,来治疗一种或多种类型的肿瘤。另外,细胞周期调节蛋白E/CDK2和细胞周期调节蛋白B/CDK1激酶分别在G1/S期和G2/M过渡中的关键作用,为治疗性干预抑制癌的解调控的细胞周期进展提供了其他靶位。
其他蛋白激酶CHK1在细胞周期进程中起关卡的重要作用。关卡是通过影响细胞周期调节蛋白依赖性激酶的形成、活化和随后的失活来协调细胞周期进程的控制系统。关卡防止在不适当时间的细胞周期进展,当细胞停滞时维持细胞的代谢平衡,和在某些情况当关卡的要求没有得到满足时,诱导细胞调亡(程序性细胞死亡)。参见O’Connor,“癌症观察”,29,151-182(1997);Nurse,Cell,91,865-867(1997);Hartwell等人,Science,266,1821-1828(1994);Hartwell等人,Science,246,629-634(1989)。
有一系列的关卡监测基因组的完整性,一旦检测到DNA损伤,这些“DNA损伤关卡”封阻在G1和G2期的细胞周期进程,并减缓通过S期的进程。O’Connor,“癌症观察”,29,151-182(1997);Harwell等人,Science,266,1821-1828(1994)。这种作用能在基因组复制和随后的将该遗传物质分离到新的子细胞发生之前,使DNA修复过程完成它们的任务。重要的是,在人癌中最通常突变的基因,即p53肿瘤抑制基因,产生DNA损伤关卡蛋白,它在DNA损伤后封阻G1期中的细胞周期进程和/或诱导细胞调亡(程序性细胞死亡)。Hartwell等人,Science,266,1821-1828(1994)。p53肿瘤抑制基因还显示出具有强化细胞周期的G2期中DNA损伤关卡作用的能力。参见,Bunz等人,Science,282,1497-1501(1998);Winters等人,Oncogene,15,3025-3035(1997)。
由于p53肿瘤抑制基因途径在人癌中的重要特性,利用p53缺陷型癌症中的易损性的治疗性干预已被密切关注。一种显现的易损性存在于p53缺陷型癌细胞中G2关卡的操作中。由于癌细胞缺少G1关卡控制,它们特别易于失去最后的残留的屏障,该屏障保护它们免受DNA破坏剂(G2关卡)的杀癌作用。G2关卡受从酵母保存到人都是保守的控制系统的调控。在此保守的系统中重要的是激酶CHK1,其从DNA损伤的传感复合物转导信号,以抑制细胞周期调节蛋白B/Cdc2激酶(促进有丝分裂的入口)的活化。参见Peng等人,Science,277,1501-1505(1997);Sanchez等人,Science,277,1497-1501(1997)。已显示CHK1的失活将消除由DNA损伤(由抗癌药或内源性DNA损伤造成的)诱导的G2停滞,并因此择优地杀死形成的关卡缺陷型细胞。参见Nurse,Cell,91,865-867(1997);Weinert,Science,277,1450-1452(1997);Walworth等人,Nature,363,368-371(1993);和Al-Khodairy等人,Molec.Biol.Cell,5,147-160(1994)。
选择性操纵癌细胞中的关卡控制在癌症的化疗和放疗疗法中提供能广泛的应用,而且还能提供人类癌“基因组不稳定”的普通标记以用作破坏癌细胞的选择性基础。许多因子在DNA破坏关卡控制中将CHK1作为关键靶位。对其和功能相关的激酶(如Cds/CHK2,最近发现的与CHK1联合调节S期进程的激酶,参见Zeng等人,Nature,395,507-510(1998);Matsuoka,Science,282,1893-1897(1998))的抑制剂的阐明能为治疗癌症提供有价值的新治疗途径。
整联蛋白受体与ECM的结合引发受FAK(粘着斑激酶)调节的细胞内信号,FAK参与细胞运动性、细胞增生和存活。在人类癌症中,FAK的过量表达表示可能通过其在整联蛋白调节的信号途径中的作用的肿瘤生成和转移。
酪氨酸激酶可以是受体类型的(具有细胞外、跨膜和细胞内区域)或非受体类型(完全是细胞内的)。
据信至少一种类型的非受体蛋白酪氨酸激酶(称为LCK),调节T细胞中自细胞表面蛋白(Cd4)与交联的抗Cd4抗体相互作用产生的信号的转导。Bolen,Oncogene,8,2025-2031(1993)(本文将其纳入作为参考)提供了更详细的非受体酪氨酸激酶的讨论。
除了上述鉴定的蛋白激酶外,许多其他蛋白激酶也已被视为是治疗的靶位,许多出版物公开了激酶活性的抑制剂,参见:McMahon等人,Oncologist,5,3-10(2000);Holash等人,Oncogene,18,5356-62(1999);Thomas等人,J.Biol.Chem,274,36684-92(1999);Cohen,Curr.Op.Chem.Biol.10,544-49(1999);McMahon等人,Current Opinion in Drug Discovery & Development,1,131-146(1998);Strawn等人,Exp.Opin.Invest.Drugs,7,533-573(1998)。WIPO国际出版物公开了某些取代的3-氰基喹啉作为蛋白激酶抑制剂。就如本领域技术人员可以理解的,理想的激酶抑制剂既要具有与靶标激酶的高度亲力又要具有相对其他蛋白激酶的高度选择性。

在一些实施例中,不分离式VII的化合物,而是在室温-80℃之间的温度(较佳地50℃)继续反应1-24小时,而将其直接转化成式I的化合物。常规的后处理和纯化得到终产物化合物I。或者,分离并纯化式VII的化合物,然后在-78℃到室温之间的温度,在适当的溶剂(如THF)中,用合适的碱(如叔-丁醇钾、六甲基二氮硅(silazide)锂或二异丙基氨化锂)处理0.5-24小时,将其转化成式I的化合物。各种式VI的化合物是可购得的或已知的,如2-(氯甲基)苯并咪唑,2-(氯甲基)喹啉、2-吡啶甲基氯化物、2-乙酰氨基-4-(氯甲基)噻唑、6-(氯甲基)-2-异丙基嘧啶-4-醇、4-氯甲基-2-(4-氯苯基)噻唑、3-(氯甲基)-1,2,4-噁二唑、3-(氯甲基)-5-(3,5-二甲基异噁唑-4-基)-1,2,4-噁二唑、3-溴甲基-6,7-二甲氧基-1-甲基-2(1h)-喹喔啉酮(quinoxalinone)、2-氯甲基-5-甲氧基苯并咪唑、5-(叔丁基)-3-(氯甲基)-1,2,4-噁二唑、5-氯-3-(氯甲基)-1,2,4-噻二唑、3-(氯甲基)-5-(3-噻吩基)-1,2,4-噁二唑、5-[4-(氯甲基)-1,3-噻唑-2-基]异噁唑、5-(氯甲基)-3-[3,5-二(三氟甲基)苯乙烯基]-1,2,4-噁二唑、5-氯-4-(氯甲基)-1,2,3-噻二唑、5-(氯甲基)-3-(4-氯苯基)-1,2,4-噁二唑、3-氯-2-(氯甲基)-5-(三氟甲基)吡啶、5-(氯甲基)-3-[(2-吡啶基磺酰基)甲基]-1,2,4-噁二唑、3-(氯甲基)-5-甲基异噁唑、2-氯甲基-4,6-二甲氧基嘧啶、3-(氯甲基)-5-(4-氯苯基)-4H-1,2,4-三唑、2-(氯甲基)-5-(4-氯苯基)-1,3,4-噁二唑、4-氯甲基-5-甲基-2-苯基-噁唑、3-(氯甲基)-1-(3,5-二氯苯基)-5-甲基-1h-吡唑和3-(氯甲基)-5-(1,2,3-噻二唑4-基)-1,2,4-噁二唑。也可用本领域技术人员已知的方法来制备式VI的化合物。参见Mylari等人,J.Med.Chem.35,457-465(1992);Baiocchi等人,Heterocyclic Chem.,16,1469-1474(1979),本文将它们全部纳入作为参考。

也可由上述通用流程制备式II的化合物,其中X是C,Y和Z各是C、N或O。在R1-异硫氰酸酯的乙腈溶液中加入氰胺,然后再加入DBU,并将反应的内部温度维持在15-30℃。搅拌1-2小时后,在催化量的叔丁基碘化铵存在下,加入发生环化和形成上述式II化合物的合适的反应物。例如,在约50℃将3-氯甲基-5-R2-[1,2,4]噁二唑(VI(a))与化合物VII反应约2小时,纯化后得到式II(a)的环化化合物。

适当温度在合适的溶剂中(较佳地室温在乙腈中),在R1-异硫氰酸酯和氰胺的溶液中加入DBU约40-80分钟,生成式II的化合物,其中X和Y是C,和Z是S。在该反应混合物中再加入DBU和溴-乙腈,在常规后处理和纯化后得到中间体2-R1-氨基-4-氨基-噻唑-5-甲腈(中间体IX)。约0℃在三乙胺/吡啶中将中间体IX与硫化氢反应生成中间体X。室温搅拌在甲醇中的化合物X与2-溴-1-R2-乙酮溶液过夜将中间体X转化成化合物II(b)。除去甲醇后,用常规分离方法处理粗制的化合物II(b),用硅胶柱层析纯化。
与制备化合物II(b)所述相同的条件下,将化合物X与α-溴-乙酸酯或α-溴内酯反应,可直接从化合物X制备式II(c)的化合物。
通过用合适的2-氨基-醇和催化量的ZnCl2处理化合物IX,在标准的酸后处理和硅胶层析纯化后得到式II(d)的化合物。也可在合适的疏质子溶剂(如甲苯)中回流IX、TMSN3和催化量的Bu2SnO溶液,从化合物IX制备式II(e)的化合物。回流后,除去溶剂,将残留物溶解于乙酸乙酯中,用适当酸的水溶液洗涤,用合适的干燥剂干燥。除去溶剂后,将残留物在乙醚中研磨,过滤收集化合物II(e)。
通过用合适的还原剂还原硝基形成氨基取代的苯基(II(f)),也可从化合物II(b)(其中R2是3-硝基苯基)直接制备式III的化合物。较佳地,在惰性气氛中将化合物II(b)(其中R2是3-硝基苯基)和氯化亚锡的溶液溶解于二甲基甲酰胺(“DMF”)中,在40-60℃间搅拌直至形成II(f)。
标准酰化条件下,将中间体II(f)与合适的酰化剂反应形成式III(a)的化合物。优选的酰化流程包括-30至0℃将化合物II(f)溶解于DMF和四氢呋喃(“THF”)中,加入吡啶和合适的酰基氯或酰基氯甲酸酯。用质子源(如甲醇)淬灭反应,通过用制备性C-18反相HPLC纯化得到化合物III(a)。
可用与上述通用流程或本文实施例所述的详细流程相类似的方法制备其他式I的化合物。通过提供靠得很近的多重配体(较佳地用由载体部分提供的支架),可以提高本发明的化合物对受体的亲和力。已显示提供这种多价且部分与部分间有最佳间隔的化合物,能显著地改善其与受体的结合。参见Lee等人,Biochem,23,4255(1984)。通过对合适的载体部分或连接基单元的选择能控制其多价和间隔。这些部分包括分子支承,它含有能与本发明化合物相关的官能团反应的多重官能团。当然也可使用各种载体,包括蛋白质如BSA或HAS、多重肽包括如五肽、十肽、十五肽等。所述肽或蛋白质可含有所需数目的氨基酸残基,在它们的侧链带有游离的氨基基团;但是,也可用其他官能团如巯基或羟基来得到稳定的键合。

除上述制剂外,还可将化合物配制成存储式制剂。这种长效的制剂可以通过移植(如皮下、肌内或眼内)给予或肌内注射给药。因此,例如这些化合物可以与合适的聚合物或疏水性材料(如作为可接受的油中的乳剂)或离子交换树脂配制,或作为微溶的衍生物(如微溶的盐)。
用于疏水性化合物的药学上可接受的载体是共溶剂系统,包括苯甲醇、非极性表面活性剂、可与水混合的有机聚合物和水相。共溶剂系统可以是VPD共溶剂系统。VPD是用无水乙醇配制的3%w/v苯甲醇、8%w/v非极性表面活性剂聚山梨醇酯80和65w/v聚乙二醇300溶液。VPD共溶剂系统(VPD:5W)含有与5%葡萄糖水溶液以1∶1稀释的VPD。此共溶剂系统能很好地溶解疏水性化合物,且全身给药时其本身产生极低的毒性。自然,共溶剂系统的比例可以变化很大,而不破坏其溶解性和毒性特性。另外,共溶剂成分也可变化:例如可加入其他低毒性的非极性表面活性剂来取代聚山梨醇酯80;聚乙二醇的分级度也可变化;其他生物相容性聚合物也可替代聚乙二醇,如聚乙烯基吡咯烷酮;和可用其他糖或多糖来代替葡萄糖。
另外,可用疏水性药物化合物的其他送递系统。脂质体和乳液是疏水性药物已知的送递运载体或载体实例。可以用某些有机溶剂如二甲基亚砜,虽然有较高细胞毒性的危险。另外,可用缓释系统如含有治疗剂的固态疏水性聚合物的半渗透性基体送递这些化合物。已确定了各种缓释材料且它们是本领域技术人员已知的。缓释胶囊(取决于它们的化学性质)可在几周至100天内释放化合物。取决于治疗剂的化学特性和生物学稳定性,也可用其他稳定蛋白质的策略。
药物组合物还可含有合适的固相或凝胶相载体或赋形剂。这些载体或赋形剂的实例包括碳酸钙、磷酸钙、糖、淀粉、纤维素衍生物、明胶和聚合物(如聚乙二醇)。
本发明的某些化合物还作为与药学上相容的抗衡离子一起的盐提供。药学上相容的盐可以用许多酸(包括盐酸、硫酸、乙酸、乳酸、酒石酸、苹果酸、丁二酸等)形成。盐比相应的游离碱的形式更易溶解于水性溶剂或其他质子性溶剂中。
以下实施例中详细叙述了制备本发明优选化合物的制备,但技术人员可以看出所述的化学反应易适当改进来制备本发明的大量其他蛋白激酶抑制剂。例如,通过用对本领域技术人员而言是很显然的改进可以成功地合成本发明未示范的化合物,如通过适当的保护干扰基团,通过改用本领域已知的其他合适的试剂,或通过对反应条件进行常规的改进。另外,认为其他本文所公开的反应或本领域已知的反应可用于制备本发明的其他化合物。

如下测试上述实施例化合物的活性。
测试酶的生物学试验
生长因子(如VEFG、FGF等)对细胞增生的刺激取决于它们各自受体酪氨酸激酶的自身磷酸化的诱导。所以,蛋白激酶抑制剂对由这些生长因子诱导的细胞增生的封阻能力直接与其封阻受体自身磷酸化的能力相关。为了测定这些化合物的抑制蛋白激酶的活性,设计了如下构建物。
用于试验的VEGF-R2构建物:该构建物是用于确定测试化合物抑制酪氨酸激酶活性的能力。在杆状病毒/昆虫细胞系中表达了人血管内皮生长因子受体2(VEGF-R2)的细胞质区域的构建物,其缺失激酶插入区域68个残基中的50个中心残基。在全长的VEGF-R2的1356个残基中,VEGF-R2Δ50含有残基806-939和990-1171,并且在相当于野生型VEGF-R2的激酶插入区域中含有一个点突变(E990V)。4℃,在100mM Hepes(pH7.5,含有15%甘油和5mM DTT)中,在3mM ATP和40mM MgCl2存在下,培养浓度为4μM的该酶以进行纯化的构建物的自身磷酸化。自身磷酸化后,该构建物显示其具有与野生型自身磷酸化的激酶区域构建物基本相当的催化活性。参见Parast等人,Biochemistry,37,16788-16801(1998)。
用于试验的FGF-R1构建物:用从内源性甲硫氨酸残基456起始到谷氨酸766(按Mohammadi等人,Mol.Cell.Biol.16,977-989(1996)的残基计数系统)的杆状病毒载体表达系统,表达人FGF-R1的细胞内激酶区域。另外,该构建物还含有如下3个氨基酸取代:L457V、C488A和C584S。
用于试验的LCK构建物:在昆虫细胞中表达N端缺失形式的LCK酪氨酸激酶,该缺失形式起始于氨基酸残基223到残基509蛋白末端,且在N端含有如下两个氨基酸取代:P233M和C224D。
用于试验的CHK-1构建物:用杆状病毒/昆虫细胞系表达C末端His标记的全长人CHK1(FL-CHK1)。其在476个氨基酸的人CHK1的C端含有6个组氨酸残基(6×His标记)。用常规的层析方法纯化该蛋白质。
用于试验的CDK2/细胞周期蛋白A构建物:用已出版的方法(Rosenblatt等人,J.Mol.Biol.230,1317-1319(1993))从已被杆状病毒表达载体感染的昆虫细胞纯化CDK2。从表达全长重组细胞周期蛋白A的大肠杆菌细胞纯化细胞周期蛋白A,且用有限蛋白酶解生成截短的细胞周期蛋白A构建物,并如上所述进行纯化(Jeffrey等人,Nature,376,313-320(1995年7月27日))。
用于试验的CDK4/细胞周期蛋白D构建物:用常规生物化学层析方法,从已被相应的杆状病毒表达载体共感染的昆虫细胞纯化人CDK4和细胞周期蛋白D3的复合物或细胞周期蛋白D1与人CDK4融合蛋白的复合物。
用于试验的FAK构建物:用杆状病毒载体表达系统表达人FAK的催化区域(FAKcd409)。表达的280个氨基酸区域包括甲硫氨酸409到谷氨酸689的残基。在相对于Whithey,G.S.等人(DNA Cell Biol 9,823-830,1993)出版的序列登录号L13616存在一个氨基酸取代(P410T)。用经典层析方法纯化该蛋白质。

用磷酸烯醇式丙酮酸(PEP)通过丙酮酸激酶(PK)和乳酸脱氢酶(LDH)的作用,将伴随磷酰基转移至合成的底物肽Syntide-2(PLARTLSVAGLPGKK)的从ATP产生ADP的过程偶联于NADH的氧化。用HP8452分光光度计观察340nm吸光度的减少(e340=6.22cm-1mM-1)来监测NADH的氧化。以下为典型反应溶液:含4mN PEP;0.15mM NADH;28单位LDH/ml;16单位PK/ml;3mM DTT;0.125mM Syntide-2;0.15mM ATP;和25mM MgCl2的50mM TRIS(pH7.5)和400mM NaCl。用10nMFL-CHK1引发试验。通过测定各浓度试验化合物存在下酶的初始活性确定Ki值。用Enzyme Kinetic and Kaleidagraph软件分析数据。
CDK2/细胞周期蛋白A和CDK4/细胞周期蛋白D试验
通过酶促时间依赖性的将[32P]ATP的放射性磷掺入成视网膜细胞瘤蛋白质的重组片断的量化来测定依赖细胞周期蛋白的激酶活性。除非特别指出,以总体积50μl,在10mM HEPES(N-[2-羟乙基]哌嗪-N’-[2-乙磺酸](pH7.4)、10mMMgCl2、25μM腺苷三磷酸(ATP)、1mg/ml卵白蛋白、5μg/ml亮抑蛋白酶肽、1mM二硫赤藓糖醇、10mM β-甘油磷酸酯、0.1mM钒酸钠、1mM氟化钠、2.5mM乙二醇-二(β-氨基乙醚)-N,N,N’,N’-四乙酸(EGTA)、2%(v/v)二甲基亚砜和0.03-0.2μ Ci[32P]ATP存在下,在96孔板中进行试验。底物(0.3-0.5μg)是纯化的重组成视网膜细胞瘤蛋白片段(Rb)(天然成视网膜细胞瘤蛋白的残基386-928;62.3kDa,含有天然106-kDa蛋白质中所发现的主要磷酸化位点,以及为了易于纯化的6个组氨酸残基)。用CDK2(150nM CDK2/细胞周期蛋白A复合物)或CDK4(50nM CDK4/细胞周期蛋白D3复合物)引发这些反应,在30℃培育,20分钟后加入乙二胺四乙酸(EDTA)至250mM终止反应。然后用96孔多功能过滤装置在硝化纤维素膜上捕捉磷酸化的底物,反复用0.85%磷酸洗涤除去未掺入的放射标记物。将干燥的硝化纤维素膜曝光于磷光成像仪以量化放射性。测定不同浓度化合物存在时酶的活性,减去无酶时的背景放射性,确定表观Ki值。在常规的测定条件下,通过测定初速度对ATP浓度的依赖性确定各酶的动力学参数(ATP的kcat、Km)。将数据用Kaleidagraph(Synergy软件)拟合于竞争性抑制的方程式,或用软件KineTic(BioKin,Ltd.)拟合于竞争性紧密结合抑制的方程式。已知的CDK4和CDK2抑制剂的测定Ki值与出版的IC50值相一致。无论是与全长细胞周期蛋白D3或是与截短细胞周期蛋白D3构建物结合,CDK4的比活性都是相同的,两种复合物对所选的抑制剂均得到极类似的Ki值。
FAK试验
FAK HTS使用了由LJL Biosystems提供的荧光偏振试验。激酶反应含有:100mM Hepes pH7.5、10mM MgCl2、1mM DTT、1mM ATP和1mg/ml聚Glu-Tyr(4∶1)。加入5nM FAKcd409引发反应。加入EDTA终止反应,然后加入荧光标记的肽和抗磷酸酪氨酸抗体(由LJL Biosystems提供)。在Analyst(LJL)探测器上读取抑制结果。
HUVEC增生试验
本试验用于测定测试化合物抑制人脐静脉上皮细胞(“HUVEC”)的生长因子刺激增生的能力。用T75烧瓶中的EGM2培养基(Clonetics Corp)冻融HUVEC细胞(3-4代,Clonetics,Corp.)。24小时后在烧瓶中加入新鲜的EGM2培养基。4或5天后,用新的培养基(补充有10%胎牛血清(FBS)、60μg/ml内皮细胞生长补充剂(ECGS)和0.1mg/ml肝素的F12K培养基)培育这些细胞。此后用指数生长期的HUVEC的细胞进行试验。将1万到1.2万个HUVEC细胞置于含有100μl丰富培养基(上述)的96孔板上。使细胞在此培养基中附着24小时。然后通过吸取除去培养基,在各孔中加入105μl饥饿培养基(F12K+1%FBS)。24小时后,将15μl溶解于1%DMSO(饥饿培养基配制)的测试药剂或将该载体单独加到各试验孔中,DMSO的终浓度为0.1%。1小时后,除那些含有未处理对照的孔外,在所有孔中加入30μl VEGF(30ng/ml)饥饿培养基,VEGF的终浓度为6ng/ml。72小时后用MTT染料还原定量细胞的增生,此时细胞与MTT(Promega Corp.)接触了4小时。加入终止溶液(Promega Corp.)终止染料还原,在96孔分光光度平板读数仪上读取595λ的吸光度。
用相应于测试药剂各浓度的A595的曲线拟合计算IC50值;通常,使用7个间隔0.5log的浓度,各浓度一式三份测试。为筛选化合物文库平板,使用1种或2种浓度(每个浓度一个孔),并按如下方程式计算%抑制:
%抑制=(对照-测试)/(对照-饥饿)
其中:
对照=存在VEGF而无测试药剂时的A595
测试=存在VEGF和测试药剂时的A595
饥饿=VEGF和测试试剂都不存在时的A595
癌细胞增生(MV522)试验
为了确定蛋白激酶抑制剂在治疗癌症中是否有治疗作用,重要的是证明抑制剂封阻应答生长因子(参与调节增生性紊乱)的细胞增生中的能力。在癌细胞中评估细胞增生的流程与在HUVEC细胞中的评估类似。在生长培养基(补充有2mM谷氨酰胺和10%FBS的RPMI1640培养基)中培育2000个肺癌细胞(自美国组织培养物保藏所得到的MV522细胞系)。在加入测试药剂和/或载体前,让细胞附着1天。同时用与HUVEC试验中所用的相同测试试剂处理这些细胞。在接触测试药剂72小时后,用MTT染料还原试验定量细胞的增生。与HUVEC细胞的5天相比,该试验的总长度为4天,因为MV522相比没有用饥饿培养基培育。

大鼠的视网膜血管是在出生后1天到出生后14天(P1-P14)间发育的。该过程依赖VEGF的活性(J.Stone等人,J.Neurosci,15,4738(1995))。已有的研究表明VEGF也作为血管早期发育中视网膜血管的存活因子(Alon等人,Nat.Med.1,1024(1995))。为了评估特定化合物体内抑制VEGF活性的能力,用合适的载体配制这些化合物,通常用50%聚乙二醇(平均分子量400道尔顿)和去离子水配制的50%的300mM蔗糖溶液,通常,将2微升(2μl)药物溶液注射入出生8或9天的大鼠眼睛的中间玻璃体中。玻璃体内注射后第6天,处死动物,将视网膜与其他眼睛组织分开。然后将分离出的视网膜进行特异性染色内皮细胞的组织化学染色流程(Lutty和McLeod,Arch,Ophtalmol,110,267(1992)),以显示组织样品中的血管化的程度。然后将各视网膜平置在载玻片上,检验血管化的程度。有效的化合物抑制视网膜血管系统的进一步发育,并诱导除最大血管外的所有血管的退化。用血管退化的量来评估体内给药后化合物的相对效力。将血管的退化分成1-3个加号为主观尺度,一个加号表示判为约25%或更少的可检测的退化,2个加号表示约退化25-75%,三个加号表示几乎全部退化(约75%或更多)。在发育模式中,实施例B(30)的化合物是测试至今最有效的化合物,当给予2μl的5mg/ml初始药物浓度时可评为2个加号(++)。
体内分析早熟性视网膜病的新生大鼠模型的视网膜血管发育
用VEGF依赖性视网膜新生血管化的第二模式来评估这一系列化合物的活性。在该模式(Penn等人,Invest,Ophthalmol.Vis.Sci.36,2063(1995))中,将幼大鼠(n=16)与它们的母亲一起置于电脑控制的区室内(调节氧气的浓度)。将这些动物与50%浓度的氧气接触24小时,然后在10%浓度氧气中24小时。如此交替的高氧和低氧重复7次,其后将这些动物移到室内空气(P14)。在移到室内空气时玻璃体内注射给予这些化合物,6天后处死动物(P20)。然后取出分离的视网膜,染色固定和如上所述用开发的方法分析。并如以上的发育模式所述对有效性分级。实施例D(74)是该模式数据测试的化合物中至今最有效的(++)。
下表总结了用各种试验测试化合物的结果,其中符号“%@”表示在所示浓度的抑制百分比,“NT”表示没有抑制。
