Description
发明背景
本发明的目标是发现新的具有重要特性的化合物,尤其是可以用于制备药物的那些化合物。
本发明涉及化合物和化合物在抑制、调控和/或调节由激酶(尤其是酪氨酸激酶)引起的信号转导中的用途,此外,还涉及包含这些化合物的药物组合物和该化合物用于治疗激酶诱导的疾病的用途。
因为蛋白激酶几乎调节每种细胞代谢过程,包括代谢、细胞增殖、细胞分化和细胞存活,所以,它们是各种疾病状态的治疗干预的诱人靶向。例如,蛋白激酶起到关键作用的细胞周期控制和血管生成是与许多疾病相关的细胞代谢过程,例如但不局限于:癌症,炎症性的疾病,异常血管生成和与其相关的疾病,动脉粥样硬化,黄斑变性,糖尿病,肥胖症和疼痛。
在柱状细胞活化之后的信号途径中的关键情况之一是酪氨酸激酶Syk的活化。在哮喘和过敏障碍中,柱状细胞通过释放促炎症介质和细胞素而起到关键性作用。抗原介导的FcεRJ(IgE的高亲和性受体)的聚集导致柱状细胞的活化。这引发一系列导致介质(包括组胺、蛋白酶、白细胞三烯和细胞素)释放的信号状况。这些介质导致血管通透性提高、粘液产生、支气管收缩、组织降解和炎症,因此在哮喘和过敏障碍的病源和症状中起到关键作用。Syk激酶充当所有随后的导致介质释放的信号的主要引发剂。Syk激酶在信号通道中的关键作用可以通过包含Syk激酶的SH2域的蛋白完全抑制介质释放而得到证明,这种蛋白起到Syk激酶的抑制剂的作用(J. A.Taylor等人Molec.and
Cell Biol,15: 4149-4157(1995))。
Syk(脾脏-酪氨酸-激酶)是72 kDa非受体酪氨酸激酶,属于胞内酪氨酸激酶的子族,其包括ZAP70、Pyk2、Abl、Tie2、KDR和HER,还有其它的激酶。Syk是FcR(FcγRI、II、III、FcεRI、FcαR)和BCR信号的主要调节剂,并且在整个造血系统中、以及在纤维母细胞、破骨细胞、肝细胞、上皮和神经元细胞中表达。除了C端激酶域之外,SYK还显示了两个SH2域和超过10个自磷酸化位置1。
借助于它的两个SH2域,SYK特异性地补充至磷酸化的ITAMs(基于免疫受体酪氨酸的活化基序,存在于免疫受体中,例如FcγRI,IIA,IIIA,FcαR,FcεRI和BCR,由单核白细胞、巨噬细胞、柱状细胞、嗜中性白细胞和B细胞表达),并且特异性地介导由柱状细胞、B细胞、巨噬细胞、单核白细胞、嗜中性白细胞、嗜酸性粒细胞、NK细胞、DC细胞血小板和破骨细胞中的那些受体的活化所引发的免疫受体信号1,2。
当BCR交联时,Igα/Igβ的胞质尾区的ITAM基序处的酪氨酸残基被Src家族激酶Lyn磷酸化,产生SYK的引入位点(docking sites),由此补充至BCR免疫复合体。然后,SYK被Src家族激酶Lyn磷酸化,并被其活化。一旦活化,SYK将衔接子蛋白BLNK磷酸化,并通过其相应的SH2域与BTK和PLCγ2相互作用。随后,SYK磷酸化和由此活化的BTK将PLCγ2磷酸化和活化,导致IP3的形成、Ca2+调动、PKC和MAPK活化和后续的NFAT、AP-1和NFκB转录因子活化,导致B细胞的活化和表面标志物表达、细胞素释放、存活和增殖3。在柱状细胞中,过敏原活化的FcεRI被LYN和FYN磷酸化,并补充SYK,SYK随后被LYN磷酸化,并进一步自动磷酸化,变成完全活化。活化的SYK磷酸化两个衔接分子NTAL和LAT,形成包含蛋白的SH2的更多的引入位点,例如PLCγ1、vav和PI3K的p85调节亚单位,导致柱状细胞脱粒和细胞素产生4。Syk在柱状细胞的信号转导中的关键作用被下列可再现的观察结果证实:不能脱颗粒的10-15%的嗜碱性白细胞(循环柱状细胞)(得自于人供体)的Syk蛋白数量减少5,6。此外,破骨细胞的骨再吸收活性需要SYK。一旦αvβ3整联蛋白刺激破骨细胞,在DAP-12/FcγRII依赖性机理中,SYK很可能被c-Src磷酸化,导致SPL-76和 Vav3磷酸化和随后的细胞骨架重组。SYK缺乏的破骨细胞是非活性的,并且显示出有缺陷的细胞骨架重组。与此相关,SYK缺乏的胚胎显示出有缺陷的骨胳质量7,8。
BCR在淋巴结中介导的B细胞的活化,以及FcR在关节中介导的树状细胞、单核白细胞、巨噬细胞、嗜中性白细胞和柱状细胞的活化,是在风湿性关节炎(RA)期间发生的细胞病理机制的主要组成部分。此外,破骨细胞的活化导致骨和软骨破坏,这是这种病变的标志9。因此,SYK信号应该在关节炎的形成期间起到关键作用,包括炎症的周围和炎症的位点两者10。实际上,在风湿性关节炎(RA)的鼠模型中,Rigel开发的口服合适的Syk抑制剂R406使临床评分得到显著的改善,并且显著地降低血清细胞素浓度以及骨浸蚀11,12。此外,在人的RA二期研究中,这种抑制剂显示了效果(ACR评分提高)和良好的耐受性13,14,15。
在SLE中,B细胞通过产生能够形成免疫复合物的自身抗体、刺激Fc受体并且最后导致过度和长期激活炎症而实质上促使发病。在SLE的鼠模型中,用Syk抑制剂治疗导致许多类转换的胚中心(class-switched
germinal center)、缘区、新形成的和滤泡性的B细胞减少,并因此导致疾病减轻的效果18。
虽然TCR信号是通过胸腺细胞和未致敏的(naïve)T细胞中的胞内酪氨酸激酶ZAP-70传导的,但一些研究显示,分化的效应T细胞,例如,涉及于多发性脑硬化(MS)或系统性红斑狼疮(SLE)的病理生理的那些T细胞,显示了TCRzeta链的下调,并伴随有TCR/CD3链的上调和其与FcRγ的相互作用。那些研究表明,在效应细胞中,TCR/CD3/FcRgamma复合物代替ZAP-70酪氨酸激酶来补充并活化Syk。在TCR信号中,这种生理性的转换仅仅出现在效应子中,而不是出现在未致敏的或记忆T细胞中16,17,18。然后,不令人意外的是,在SLE的鼠模型中,显示SYK抑制剂延迟疾病进展,并且提高存活率17,18,19,20,21。
还发现SYK抑制剂可以用于哮喘、过敏、多发性脑硬化及其它疾病,例如血小板减少性紫癜和T或B细胞淋巴瘤1,10 , 14,22-35。用Syk抑制剂治疗病变早期的NZB/W小鼠,防止了肾病的形成,这可以通过肾小球硬化症、管损伤、蛋白尿和BUN水平降低来证明18。
参考文献
除了柱状细胞之外,Syk在其它造血细胞(包括B细胞)中也被表达,人们认为它在不成熟B细胞转变为成熟再循环B细胞所需要的传导信号方面起到主要作用(M. Turner等人Immunology
Today,21: 148(2000))。据报道,B细胞在一些炎症性病症例如狼疮(O. T. Chan等人,Immunological Rev,169:107-121(1999))和类风湿性关节炎(A.
Gause等人,Biodrugs,15(2):73-79(2001))中起重要作用。
据报道,在产生神经毒剂产物的β-淀粉样蛋白和朊病毒纤丝中,Syk还是信号级联放大的要素(C. K. Combs等人,J.
Neuroscl,19: 928-939(1999))。此外,Syk的抑制剂阻断这些神经毒剂产物的产生。由此,呋喃并吡啶衍生物可潜在地用于治疗阿尔茨海默氏病和相关的神经炎症疾病。另一个报道(Y.
Kuno等人,Blood,97,1050-1055(2001))证明了Syk在恶性进展中起重要作用。人们发现TEL-Syk融合蛋白能够转变造血细胞,表明了其在造血恶性肿瘤的发病机理中的作用。因此,呋喃并吡啶衍生物可以用于治疗某些类型的癌症。
涉及于血液恶性肿瘤的其它蛋白酪氨酸激酶包括ABL(ABLl),ARG(ABL2),PDGFβR,PDGFaR,JAK2,TRKC,FGFRl,FGFR3,FLT3和FRK。
Janus激酶(JAK)是由JAKl、JAK2、JAK3和TYK2组成的酪氨酸激酶的家族。JAK在细胞素信号中起到关键作用。激酶的JAK家族的下游底物包括信号转导物和转录活化剂(STAT)蛋白。JAK/STAT信号涉及于许多异常免疫反应的介导,例如变态反应,哮喘,自身免疫疾病,例如,移植物(异体移植物)排斥,类风湿性关节炎,肌萎缩性侧索硬化和多发性脑硬化,以及涉及实体和血液恶性肿瘤,例如白血病和淋巴瘤(对于JAK/STAT途径的药物干预的评述,参见Frank,MoI. Med. 5,432:456(1999)和Seidel等人Oncogene 19,2645-2656(2000))。JAK2是充分确认的靶向,在脊髓增生病(MPDs)(包括真性红细胞增多症(PV),特发性血小板增多症,慢性自发性骨髓纤维化,具有骨髓纤维化的骨髓组织异生,慢性粒细胞性白血病,慢性骨髓单核细胞性白血病,慢性嗜酸细胞性白血病,嗜酸性白细胞增多综合征和系统肥大细胞病)的治疗中具有强大潜力。
Fms类酪氨酸激酶3(FLT3),亦称为FLK-2(胎儿肝激酶2)和STK-I(干细胞激酶1),在造血干细胞的增殖和分化中起重要作用。FLT3受体激酶在正常造血细胞、胎盘、生殖腺和脑中表达。然而,这种酶在80%以上的骨髓性患者的细胞中和一部分急性淋巴母细胞性白血病细胞中以很高的水平表达。此外,这种酶还可以在淋巴急变的(lymphoid
blast crisis)慢性粒性白血病患者的细胞中发现。据报道,在30%的急性骨髓性白血病(AML)中和同样在急性淋巴母细胞性白血病(ALL)的下位组中,FLT3激酶发生突变(Gilliland等人Blood 100,1532-1542(2002);
Stirewalt等人Nat. Rev. Cancer,3,650-665(2003))。在FLT3中,最常见的活化突变是在近膜区域内的内部衔接重复,而在该激酶域中的点突变、插入或缺失是不太常见的。一些这种突变体FLT3激酶是结构上活性的激酶。FLT3突变与预后差相关(Malempati等人,Blood,104,11(2004))。正在研发超过12种已知的FLT3抑制剂,其中一些有希望产生临床上抗AML的效果(Levis等人Int. J. Hematol,52,100-107(2005))。
据报道,一些小分子FLT3抑制剂在具有FLT3-活化突变的细胞系中可有效诱导细胞程序死亡,并且可使其骨髓细胞中表达突变体FLT3的小鼠的存活时间延长(Levis等人Blood,99,3885-3891(2002);
Kelly等人Cancer Cell,1,421-432(2002);
Weisberg等人Cancer Cell,1,433-443(2002);
Yee等人Blood,100,2941-2949(2002))。
BTK(非受体酪氨酸激酶的Tec家族的成员)是在所有造血细胞类型中表达的信号酶,T淋巴细胞和天然杀伤细胞除外。在文献记载了BTK在连接细胞表面B细胞受体刺激与下游胞内反应的B细胞信号途径中起的作用。BTK还是B细胞演变、激活、信号和存活的调节剂(Kurosaki,Curr
Op Imm,2000,276-281;
Schaeffer 和 Schwartzberg,Curr Op Imm 2000,282-288)。此外,BTK通过其它造血细胞信号传导途径产生生理效应,例如,Toll类受体(TLR)和在巨噬细胞中的细胞素受体介导的TNF-a产物,在柱状细胞中的IgE受体(FcepsilonRl)信号,在B族淋巴样细胞中的抑制Fas/APO-1凋亡信号,和胶原刺激的血小板凝聚。
尤其是,本发明涉及化合物和化合物的用途,其中抑制、调控和/或调节Syk引起的信号转导起到作用。
因此,合成特异性地抑制、控制和/或调节酪氨酸激酶(尤其是Syk)引起的信号转导的小分子化合物是合乎需要的,并且是本发明的目标。
此外,本发明的目标是合成能够预防和治疗类风湿性关节炎、全身性狼疮、哮喘、过敏性鼻炎、ITP、多发性脑硬化、白血病、乳腺癌和恶性黑素瘤的新化合物。意外地,我们已经鉴定了呋喃并吡啶,其能够选择性地抑制SYK、BTK、KDR、Src、Zap70、Fak、Pyk2、Flt3或Jak,或抑制这些激酶的选择作用。
已经发现,按照本发明的化合物和其盐具有很有价值的药理学特性,同时具有很好的耐受性。
本发明具体地涉及抑制、控制和/或调节Syk引起的信号转导的式I化合物、包含这些化合物的组合物和其用于治疗Syk诱导的疾病和不适(complaint)的方法。
此外,式I的化合物可以用于分离Syk和研究Syk的活性或表达。此外,它们尤其适合于诊断与未调节的或紊乱的Syk活性有关的疾病的方法。
宿主或患者可以属于任何哺乳动物,例如,灵长类,尤其是人;啮齿类,包括小鼠、大鼠和仓鼠;兔;马,牛,狗,猫,等等。动物模型是使人感兴趣的,用作试验研究的动物模型,能够提供治疗人疾病的模型。
可以通过体外试验来测定具体细胞对于按照本发明化合物的治疗的敏感性。典型地,将细胞的培养物与各种浓度的按照本发明的化合物结合一段时间,结合时间应该足以使活性剂(例如抗IgM)诱导细胞响应,例如,表面标志物的表达,通常在大约一小时和一周之间。可以使用得自于血液或活检样品培养的细胞来进行体外试验。使用能够辨别标志物的特定抗体,通过流式细胞仪评价被表达的表面标志物的数量。
剂量根据使用的具体化合物、具体疾病、患者状态等等而变化。治疗剂量典型地足以显著地减少靶组织中的不希望有的细胞群体,同时保持患者的生存能力。治疗通常持续至细胞载荷出现相当大的减少为止,例如,减少至少大约50%,并且可以持续至身体内基本上不能检出不希望有的细胞为止。
为了鉴定信号转导途径和检测各种信号转导途径之间的相互作用,许多科学家开发了合适模型或模型系统,例如,细胞培养物模型(例如,Khwaja等人,EMBO,1997,16,2783-93)和转基因动物的模型(例如,White等人,Oncogene,2001,20,7064-7072)。为了测定信号转导级联中的某些阶段,可以使用相互作用化合物,以便调节信号(例如,Stephens等人,Biochemical J.,2000,351,95-105)。按照本发明的化合物还可以在动物和/或细胞培养物模型中或在本申请提到的临床疾病中用作测试激酶依赖性信号转导途径的试剂。
激酶活性的测定是本领域技术人员众所周知的技术。在文献(例如,Campos-González R. and Glenney,Jr.,J.R. 1992,J. Biol. Chem.
267,14535页)中,描述了使用底物例如组蛋白(例如,Alessi等人,FEBS Lett. 1996,399,3,333-338页)或碱性髓鞘蛋白来测定激酶活性的一般测试系统。
为了鉴定激酶抑制剂,许多试验系统是合适的。在闪烁近似测定(Sorg等人,J.
of. Biomolecular Screening,2002,7,11-19)和flashplate试验中,测定作为底物的蛋白或肽(含有γATP)的放射性磷酸化。在抑制化合物的存在下,可检测放射性信号的降低,或检测不出放射性信号。此外,均相时间分辨荧光共振能量转移(HTR-FRET)和荧光偏振(FP)技术可合适地作为测定法(Sills等人,J. of Biomolecular Screening,2002,191-214)。
其它非放射性的ELISA测定法使用特定磷酸抗体(phospho-antibodies
,磷酸-ABs)。磷酸-AB只结合磷酸化底物。可以使用辅助的过氧化酶共轭的抗羊抗体(Ross等人,2002,Biochem. J.),通过化学荧光来检测这种结合。
现有技术

der organischen Chemie[Methods of Organic Chemistry],Georg-Thieme-Verlag,Stuttgart)所述,确切地说,在已知和适合于所述反应的反应条件下。还可以使用本身已知的替代方法,这种方法在本文中没有更详细地提及。
式II和III的原料化合物通常是已知的化合物。然而,如果它们是新化合物,可以用本身已知的方法制备它们。
使用的式II的哒嗪酮(如果不可商业购买)通常用W. J. Coates,A. McKillop,Synthesis,1993,334-342的方法制备。
优选,可以如下获得式I的化合物:在第一步,式IIa的化合物与式IIIa的化合物反应,得到式IVa的化合物。
在式IIIa的化合物中,L优选代表
该反应通常在Suzuki类型偶合条件下进行。
根据使用的条件,反应时间在几分钟和14天之间,反应温度在大约-30°和140°之间,通常在0°和100°之间,尤其是在大约60°和大约90°之间。
合适惰性溶剂的例子是烃,例如己烷,石油醚,苯,甲苯或二甲苯;氯化烃,例如三氯乙烯,1,2-二氯乙烷,四氯化碳,氯仿或二氯甲烷;醇,例如甲醇,乙醇,异丙醇,正丙醇,正丁醇或叔丁醇;醚,例如二乙醚,二异丙醚,四氢呋喃(THF)或二噁烷;乙二醇醚,例如乙二醇一甲基或一乙基醚,甘醇二甲醚(二甘醇二甲醚);酮,例如丙酮或丁酮;酰胺,例如乙酰胺,二甲基乙酰胺或二甲基甲酰胺(DMF);腈,例如乙腈;亚砜,例如二甲亚砜(DMSO);二硫化碳;羧酸,例如甲酸或乙酸;硝基化合物,例如硝基甲烷或硝基苯;酯,例如乙酸乙酯,或所述溶剂的混合物。

两个反应步骤通常在上面给出的Suzuki类型偶合条件下进行。
此外,可以将式I的化合物转变为另一种式I的化合物,例如,将硝基还原为氨基(例如,在惰性溶剂例如甲醇或乙醇中,在Raney镍或Pd/碳上氢化)。
此外,可以使用酰氯或酸酐,用常规方式将游离氨基酰化,或使用未取代的或取代的烷基卤将其烷基化,有利地在惰性溶剂中,例如二氯甲烷或THF,和/或在碱例如三乙胺或吡啶的存在下,在-60和+30°之间的温度下。
此外,可以如下获得式I的化合物:通过溶剂解(尤其是水解)或氢解,从它们的功能性衍生物中释放它们。
溶剂解或氢解的优选的起始原料是包含相应的被保护氨基和/或羟基(代替一个或多个游离氨基和/或羟基)的那些,优选携带氨基保护基(代替与N原子键合的H原子)的那些,例如与式I相符的那些,但包含NHR'基团(其中R'是氨基保护基,例如BOC或CBZ)代替NH2基团。
此外,优选携带羟基保护基(代替羟基的H原子)的起始原料,例如,与式I相符但包含R''O-苯基(其中R''是羟基保护基)代替羟基苯基的那些。
多个相同或不同的保护的氨基和/或羟基也可以存在于起始原料的分子中。如果存在的保护基彼此不同,在很多情况下可以选择性地使它们断裂。
一般地说,术语“氨基保护基”是已知的,并且涉及适合于来保护(封闭)氨基抵抗化学反应的基团,但在目标化学反应已经在分子的其它位置进行之后,容易除去它们。典型的这种基团尤其是未取代的或取代的酰基、芳基、芳烷氧基甲基或芳烷基。因为在目标反应(或反应顺序)之后除去氨基保护基,所以,它们的类型和大小并不重要;然而,优选具有1-20个碳原子的那些保护基,尤其是1-8个碳原子。可以与本方法结合来广义地理解术语“酰基”。它包括衍生自脂族、芳基脂族、芳香或杂环羧酸或磺酸的酰基,尤其是烷氧羰基、芳氧羰基,特别是芳烷氧基羰基。这种酰基的例子是烷酰基,例如乙酰基,丙酰基和丁酰基;芳烷酰基,例如苯乙酰基;芳酰基,例如苯甲酰基和甲苯基(tolyl);芳氧基烷酰基,例如POA;烷氧羰基,例如甲氧羰基,乙氧羰基,2,2,2-三氯乙氧羰基,Boc和2-碘乙氧羰基;芳烷氧基羰基,例如CBZ(“苄氧羰基”),4-甲氧基苄氧羰基和FMOC;和芳基磺酰基,例如Mtr、Pbf和Pmc。优选的氨基保护基是BOC和Mtr,此外优选CBZ、Fmoc、苄基和乙酰基。
一般地说,术语“羟基保护基”同样是已知的,并且涉及适合于来保护(封闭)羟基抵抗化学反应的基团,但在目标化学反应已经在分子的其它位置进行之后,容易除去它们。典型的这种基团是上述未取代的或取代的芳基、芳烷基或酰基,此外也可以是烷基。因为在目标化学反应或反应顺序之后需要再次除去羟基保护基,所以,它们的性质和大小并不重要;优选具有1-20个碳原子的基团,尤其是1-10个碳原子。羟基保护基的例子尤其是叔丁氧羰基,苄基,对硝基苯甲酰基,对甲苯磺酰基,叔丁基和乙酰基,其中尤其优选苄基和叔丁基。优选,以叔丁基酯形式保护门冬氨酸和谷氨酸中的COOH基团(例如,Asp(OBut))。
根据使用的保护基,例如,使用强酸,有利地使用TFA或高氯酸,但还可以使用其它强无机酸,例如盐酸或硫酸,强有机羧酸,例如三氯乙酸或磺酸,例如苯磺酸或对甲苯磺酸,使式I化合物从它们的功能性衍生物中释放出来。可以存在额外的惰性溶剂,但并不总是必需的。优选,合适的惰性溶剂是有机溶剂,例如羧酸,例如乙酸,醚,例如四氢呋喃或二噁烷,酰胺,例如DMF,卤代烃,例如二氯甲烷,此外还优选醇,例如甲醇,乙醇或异丙醇,和水。此外,上述溶剂的混合物也是合适的溶剂。优选,使用过量的TFA,不用进一步加入溶剂,优选,以乙酸和70%高氯酸(比例9:1)的混合物形式使用高氯酸。优选,断裂的反应温度在大约0°和大约50°之间,优选在15和30°(室温)之间。
优选,例如,可以使用TFA/二氯甲烷,或使用大约3至5N HCl/二噁烷,在15-30°,使BOC、OBut、Pbf、Pmc和Mtr基团断裂,使用大约5至50%二甲胺、二乙胺或哌啶的DMF溶液,在15-30°,使FMOC基团断裂。
使用三苯甲基来保护氨基酸组氨酸、天冬酰胺、谷氨酰胺和半胱氨酸。根据目标最终产物来使它们断裂,使用TFA/10%硫苯酚,三苯甲基从所有的所述氨基酸上断裂;使用TFA/苯甲醚或TFA/苯甲硫醚,只有His、Asn和Gln的三苯甲基断裂,而它还保留在Cys侧链上。
使用Pbf(五甲基苯并呋喃基)基团来保护Arg。例如,使用TFA/二氯甲烷将其断裂。
例如,在催化剂(例如贵金属催化剂,例如钯,优选,在载体例如碳上)的存在下用氢处理,可以断裂掉氢解可除去的保护基(例如CBZ或苄基)。本文中,合适的溶剂是上述那些溶剂,尤其是,例如,醇,例如甲醇或乙醇,或酰胺,例如DMF。氢解通常在大约0和100°之间的温度下、在大约1和200巴之间的压力下进行,优选20-30°和1-10巴。CBZ基团的氢解很成功,例如,在5至10% Pd/C上,在甲醇中,或使用甲酸铵(代替氢),在Pd/C上,在甲醇/DMF中,在20-30°。

体外试验的说明
SYK
快速板试验
以384孔快速板试验(例如,对于Topcount测定)或384孔成像快速板试验(对于LEADseeker测定)形式进行该激酶试验。
在有或者没有试验化合物的条件下,在30℃,将2.5
nM SYK、400 nM生物素-Aha-Aha-KEDPDYEWPSAKK和10µM ATP(用0.3µCi 33P-ATP/孔进行示踪)在50µl总体积(60 mM Hepes,10 mM
MgCl2,1.2 mM二硫苏糖醇,0.02% Brij35,0.1%
BSA,pH7.5)中培养1小时。用25µl 200 mM EDTA终止该反应。在30℃保持30分钟之后,除去液体,将每个孔用100µl 0.9%氯化钠溶液洗涤三次。在0.1µM星孢菌素的存在下,测定非特异性反应。用Topcount(当使用快速板时)或用LEADseeker(当使用成像快速板时)分别测定放射性。用IT部门提供的程序工具(例如,Symyx Assay
Explorer,Genedata Screener)计算结果(例如,IC50值)。
使用
Caliper
生命科学技术进行酶试验
本文所描述的试验是在Caliper Life Sciences LC3000系统上进行的。在酶反应的最后,通过测定磷酸化或未磷酸化的荧光标记底物肽的相对量,这种技术提供酶活性的数据。给整个样品施加电位差,分辨这些不同状态的肽。在产物(与底物相反)上存在的带电磷酸基,在两个肽之间引起不同的肽移动性。这可以通过底物和产物肽上的荧光标记物的激发来观测,并且在分析软件内以峰形式表示。
为了测定利用这种技术的激酶抑制剂的抑制活性,使用TTP Mosquito液体操作仪器,将0.25 ul合适浓度的抑制剂(在100% DMSO中)(用于剂量响应曲线计算)放入384孔板的每个孔中。向其中加入反应组分,达到25 ul的最终体积。下表表明了该报道所描述的试验的序列和浓度。标准组分是:1 mM
DTT(Sigma,D0632),1 mM
MgCl2(Sigma,M1028),100 mM HEPES pH7.5(Calbiochem,391338),0.015%
Brij-35(Sigma,B4184)。
将该反应在25℃培养90分钟,而后加入70 ul终止缓冲液(100 mM HEPES
pH7.5,0.015% Brij-35,10 mM EDTA(Sigma,E7889)),使该反应终止。
在Caliper LC 3000上,以芯片外迁移率变动分析形式,在12个单列直插式组件芯片(12 - sipper chip)上读板。以独立的峰形式分辨未磷酸化底物和磷酸化产物肽,这种峰可以直接测定底物转变为产物的百分比。可以画出百分转化率对抑制剂浓度的曲线,制作S形剂量响应曲线,可以使用GeneData Condoseo或类似的产品,利用该曲线计算IC50值。
