Abstract
本发明涉及抑制磷酸肌醇3‑激酶(PI3K)的化合物,涉及包含它们的药物组合物及其在与PI3K酶有关的障碍的治疗中的治疗用途。
Description
技术领域
本发明涉及抑制磷酸肌醇(phosphoinositide)3-激酶(在下文中称作PI3K)的化合物;具体地,本发明涉及是色烯衍生物的化合物、制备这样的化合物的方法、含有它们的药物组合物及其治疗用途。
更具体地,本发明的化合物是PI3K I类的活性或功能的抑制剂,且更具体地,它们是I类PI3K的ΡΙ3Kα、ΡΙ3Kβ、ΡΙ3Kδ和/或ΡΙ3Kγ同种型的活性或功能的抑制剂。
因此,本发明的化合物可以用于治疗许多与PI3K酶机制相关的障碍,例如呼吸性疾病,包括哮喘,慢性阻塞性肺病(COPD)和咳嗽;变应性疾病,包括变应性鼻炎和特应性皮炎;自身免疫性疾病,包括类风湿性关节炎和多发性硬化;炎症性障碍,包括炎性肠病;心血管疾病,包括血栓形成和动脉粥样硬化;恶性血液病;囊性纤维化;神经变性疾病;胰腺炎;多器官衰竭;肾病;血小板聚集;癌症;精子能动性;器官移植且特别是移植排斥(transplant rejection);移植物排斥(graft rejection);肺损伤;和疼痛,包括与下述相关的疼痛:类风湿性关节炎或骨关节炎、背痛、一般炎症性疼痛、疱疹后神经痛(posthepatic neuralgia)、糖尿病神经病变、炎症性神经性疼痛、三叉神经痛和中枢性疼痛。
背景技术
在生物化学中,激酶是将磷酸基团从高能供体分子(诸如ATP)转移至特定底物上(即被称作磷酸化的过程)的酶类型。具体地,PI3K酶是可以在肌醇环的3'-羟基基团处将磷酸肌醇(PI)磷酸化的脂质酶激酶(Panayotou等人,Trends Cell Biol 2:358-60(1992))。众所周知,位于质膜中的PI可以作为信号传递级联中的第二信使通过含有普列克底物蛋白-同源性(PH)、FYVE、PX和其它磷脂-结合结构域的船坞蛋白质起作用(Vanhaesebroeck B等人,Annu.Rev.Biochem 70,535-602,2001;Katso R等人,Annu.Rev.Cell Dev.Biol.17,615-675,2001)。
因此,PI可以作为许多细胞过程中的第二信使起作用,包括信号转导、膜运输和转运的调节、细胞骨架组构、细胞存活和死亡以及许多另外的功能。
PI可以通过两种经甘油磷酸接头连接至细胞溶质肌醇环的脂肪酸结合细胞膜的脂质双层。PI肌醇环可以被PI3K酶磷酸化,从而导致细胞生长、存活和增殖的调节。由于该原因,由PI3K酶实现的PI磷酸化是与哺乳动物细胞表面受体活化相关的大部分相关信号转导事件之一(Cantley LC,Science 296,1655-7,2002;Vanhaesebroeck B等人,Annu.Rev.Biochem 70,535-602,2001)。
基于序列同源性、结构、结合配偶体、活化模式和底物优先性,已经将PI3K酶分成3类:I类PI3K、II类PI3K和III类PI3K(Vanhaesebroeck B等人,Exp.Cell Res.253(1),239-54,1999;和Leslie NR等人,Chem.Rev.101(8),2365-80,2001)。
I类PI3K将磷酸肌醇-(4,5)-二磷酸(PI(4,5)P2)转化成磷酸肌醇-(3,4,5)-三磷酸(PI(3,4,5)P3),后者作为第二信使起作用。由PI(3,4,5)P3的细胞内水平的增加活化的信号传递级联通过5’-特异性的和3’-特异性的磷酸酶的作用被负调节(Vanhaesebroeck B等人,Trends Biochem.Sci.22(7),267-72,1997;Katso R等人,Annu.Rev.CellDev.Biol.17,615-75,2001;和Toker A,Cell.Mol.Life Sci.59(5),761-79,2002)。
II类PI3K酶是最近鉴定的PI3K类型且它们的确切功能仍然不清楚。
III类PI3K酶由单一家族成员组成,所述家族成员在结构上与I类PI3K酶相关并且似乎在胞吞作用和囊泡运输中是重要的。但是,一些证据表明III类PI3K可能涉及免疫细胞过程,诸如吞噬作用和Toll-样受体(TLR)信号传递。
I类PI3K酶可以基于其活化机制进一步分入IA类和IB类。
更详细地,IA类PI3K酶包含3种密切相关的同种型:PI3Kα、PI3Kβ和PI3Kδ,而IB类仅包含PI3Kγ同种型。这些酶是由被称作p110的催化亚基组成的异源二聚体,具有4种类型:alpha(α)、beta(β)、delta(δ)和gamma(γ)同种型,它们在组成上与调节亚基相关。前2种p110同种型(α和β)普遍存在地表达且参与细胞分化和增殖。结果,PI3Kα和PI3Kβ酶已经作为新化疗剂的开发靶标被广泛地研究。
另外,p110δ和p110γ同种型主要在白细胞中表达且在免疫应答的活化中是重要的,诸如白细胞迁移、B和T细胞活化和肥大细胞去粒。因此,PI3Kδ和PI3Kγ同种型在炎症性呼吸性疾病中是非常相关的。
目前,本领域已知的PI3K酶的抑制剂衍生物通常会抑制所述同种型(α、β、δ和γ同种型),且它们可以通过作用于所述特定同种型在不同疾病中所起的各个作用。
因此,已经广泛地开发了IA类抑制剂对一种特定PI3Kα、PI3Kβ、PI3Kδ和PI3Kγ同种型相对于另一种的比活性测定,以便分辨用于治疗与PI3K酶机制相关的障碍的合适特性。这类障碍可以包括,例如,呼吸性疾病,其选自特发性慢性咳嗽、咳嗽-变异性哮喘、与胸部肿瘤或肺癌相关的咳嗽、病毒性或病毒后咳嗽、上气道咳嗽综合征(UACS)或滴鼻后咳嗽(post nasal drip cough);或与酸和非酸的胃食管反流病相关的咳嗽、哮喘、慢性支气管炎、慢性阻塞性肺病(COPD)、间质性肺病、特发性肺纤维化(IPF)、充血性心脏病、肉样瘤病(sarcoidosis)、感染(例如百日咳)、病毒感染,包括病毒性呼吸道感染以及呼吸性疾病的病毒性恶化;非病毒性呼吸道感染,包括曲霉菌病和利什曼病;变应性疾病,包括变应性鼻炎和特应性皮炎;自身免疫性疾病,包括类风湿性关节炎和多发性硬化;炎症性障碍,包括炎性肠病;心血管疾病,包括血栓形成和动脉粥样硬化;恶性血液病;神经变性疾病;胰腺炎;多器官衰竭;肾病;血小板聚集;癌症;精子能动性;移植排斥(transplantationrejection);移植物排斥;肺损伤;和疼痛,包括与下述相关的疼痛:类风湿性关节炎或骨关节炎、背痛、一般炎症性疼痛、疱疹后神经痛、糖尿病神经病变、炎症性神经性疼痛(创伤)、三叉神经痛和中枢性疼痛。
考虑到由PI3K酶介导的病理学应答的数量,持续需要可以用于治疗多种障碍的PI3K酶的抑制剂。因此,本发明涉及新化合物,其是I类PI3K酶的PI3Kα、PI3Kβ、PI3Kδ和PI3Kγ同种型的抑制剂,由于上述原因,它们经常可以具有治疗上所需的特征。
具体地,本发明的化合物可以具有对于PI3K酶的δ同种型或对于γ和δ同种型二者远超过对于相同酶的其它同种型的选择性。

例如芳基(C1-C6)烷基的例子包括苯基甲基,在本文中也被称作苄基。例如杂芳基(C1-C6)烷基的例子包括吡啶-4-基甲基。例如(C3-C7)环烷基(C1-C6)烷基的例子包括环丙基甲基。
本文中使用的表述“环系”表示单环或二环环系,其可以是饱和的、部分不饱和的或不饱和的,诸如芳基、(C3-C7)环烷基、(C3-C6)杂环烷基或杂芳基。
本文中使用的氧代部分由(O)表示,作为对其它一般表示(例如(=O))的替代。因而,以通式的方式,羰基在本文中优选地表示为C(O),作为对其它一般表示(诸如CO、(CO)或C(=O))的替代。一般而言,加括号的基团是侧基,没有被包括在链中,且当认为有用时,使用括号来帮助区分直链化学式;例如磺酰基-SO2-也可能被表示为-S(O)2-以消除例如关于亚磺酸基(sulfinic)-S(O)O-的歧义。
本领域技术人员显而易见,当R3和R4不同时,式(I)的化合物可以含有至少一个立体中心,即在式(IA)中由带星号的碳原子(*)表示,且因此可以作为光学立体异构体存在。
其中根据本发明的化合物具有这样的至少一个立体中心,它们可以相应地作为对映异构体存在。在根据本发明的化合物具有两个或更多个立体中心的情况下,它们可以另外作为非对映异构体存在。应当理解,在本发明范围内包括所有这样的单一对映异构体、非对映异构体及其任何比例的混合物。当碳是立体中心时,基于Cahn-Ingold-Prelog命名法则基于基团的优先性指定碳(*)的绝对构型(R)或(S)。
阻转异构体是由围绕单键旋转受阻产生的立体异构体,其中对旋转的空间张力屏障高至足以允许构象异构体的分离(Bringmann G等人,Angew.Chemie Int.Ed.44(34),5384-5427,2005)。
Oki将阻转异构体定义为这样的构象异构体:其在给定的温度以超过1000秒的半衰期互变(Oki M,Topics in Stereochemistry 14,1-82,1983)。
阻转异构体与其它手性化合物的差别在于,在许多情况下,它们可以发生热平衡,而在手性的其它形式,异构化经常仅仅是化学上可能的。
通过手性拆分法诸如选择性结晶,阻转异构体的分离是可能的。在阻转-对映选择性的或阻转选择性的合成中,一种阻转异构体以另一种阻转异构体为代价而形成。阻转选择性的合成可以通过使用手性助剂进行,如Corey Bakshi Shibata(CBS)催化剂,即一种从脯氨酸衍生出的不对称催化剂;或在异构化反应有利于一种阻转异构体超过另一种阻转异构体时,通过基于热力学平衡的方案进行。
在本发明的范围内包括式(I)的化合物的外消旋形式以及单独的阻转异构体(基本上不含有其相应的对映异构体)和富含立体异构体的阻转异构体混合物。

方案3
如在方案4中所示,可以从化合物(Vb)和(Vd)合成化合物VIIIb(其中R1和R2组合以形成氧代基团(=O)且R3=R4=H,Z不存在)和化合物VIIId(其中R1和R2组合以形成氧代基团(=O),且R3=H,R4=Me,Z不存在),所述化合物(Vb)和(Vd)通过与合适的卤化剂(诸如PBr3)反应被转化成(VIIb)和(VIId),其中基团Y代表合适的离去基团诸如卤化物原子,并然后在有合适的碱如K2CO3存在下与商购可得的3-碘-1H-吡唑并[3,4-d]嘧啶-4-胺反应(方案4,步骤1和2)。通过在有膦诸如PPh3(三苯基膦)和商购可得的3-碘-1H-吡唑并[3,4-d]嘧啶-4-胺存在下与二烷基氮杂二甲酸酯如DIAD(二异丙基氮杂二甲酸酯)的Mitsunobu反应,可以从化合物(Vc)(其中R1=R2=R3=H,R4=Me)合成化合物(VIIIc)(其中R1=R2=R3=H,R4=Me,Z不存在)(方案4,步骤3)。

在当R5是被不同部分如例如4,4,5,5-四甲基-2-(噻吩-2-基)-1,3-二氧杂环戊基部分取代的杂芳族环的特定情况下,可以通过三步骤顺序从化合物XIII制备化合物XIIb(其中R1=R2=R3=H,R4=Me,Z不存在)(方案5)。通过与无机酸如HCl的水溶液的反应,通过缩醛部分的水解,可以从化合物XII制备化合物XIV(方案5,步骤1)。通过在有胺(如1-甲基哌嗪或二甲胺)和合适的氢化物供体(如三乙酰氧基硼氢化钠)存在下的还原胺化,可以从化合物XIV制备化合物XV(其中R1=R2=R3=H,R4=Me,Z不存在,且W=NMe2或N-甲基哌嗪或OH)(方案5,步骤2)。借助于与合适的有机硼试剂(XIa)的Suzuki偶联,可以将化合物(XV)(其中R1=R2=R3=H,R4=Me,Z不存在,且W=NMe2或N-甲基哌嗪或OH)进一步转化成化合物(XIIb)(方案5,步骤3)。

本发明化合物的药理学活性
PI3K酶抑制活性在无细胞测定(cell free assay)中的体外测定
人重组蛋白PI3Kα、PI3Kβ、PI3Kγ和PI3Kδ购自Millipore Ltd(Billerica,MA)。将化合物以0.5mM溶解于DMSO中,使用ADP-GloTM激酶测定法(Promega,Madison WI)根据生产商的说明书在不同浓度试验其对PI3K的活性。
简而言之,在384-孔白色平板(Greiner Bio-One GmbH,Frickenhausen)中进行激酶反应。给每个孔加载0.1μl试验化合物和2.5μl2×反应缓冲液(40mM Tris pH7.5,0.5mMEGTA,0.5mM Na3VO4,5mMβ-甘油磷酸酯,0.1mg/ml BSA,1mM DTT),其含有50μM PI和PS底物(L-α-磷脂酰肌醇钠盐和L-α-磷脂酰-L-丝氨酸,Sigma-Aldrich,St.Louis MO)和PI3K重组蛋白(PI3Kγ0.25ng/μl,PI3Kδ1ng/μl,PI3Kα0.125ng/μl,PI3Kβ1ng/μl)。
通过向每个孔中添加2.5μl 2×ATP溶液(终浓度:PI3KγATP 30μM;PI3KδATP 80μM;PI3KαATP 50μM;PI3KβATP 100μM)来开始反应,并在室温温育60min。随后,将每种激酶反应物与5μl ADP-GloTM试剂一起温育40min,从而能够耗尽未消耗的ATP。然后,向每个孔中加入激酶检测试剂(10μl)以将ADP转化成ATP,并且允许使用荧光素酶/荧光素反应测量新合成的ATP。60min温育以后,使用Wallac多标记读出器(PerkinElmer,WalthamMA)测量发光信号。
使用应用于Microsoft Excel(Microsoft,Redmont,WA)的XLfit(IDBS,Guilford,UK)中的4-参数逻辑模型进行曲线拟合和IC50计算。
本发明的化合物表现出就PI3K-δ亚基而言低于1μM的IC50,优选地低于100nM。
在PBMC测定中的PI3K酶抑制活性的体外测定
从Lonza(Basel,CH)购买人外周血单核细胞(PBMC),洗涤,并再悬浮于补充了10%FBS、2mM谷氨酰胺、100U/ml青霉素和100μg/mL链霉素(Life Technologies,Carlsbad CA)的RPMI 1640培养基(不含酚磺酞)中。将PBMC以105个细胞/孔的密度铺板在用6μg/ml抗-人CD3抗体(Biolegend,San Diego CA)涂布的96-孔平板中。
将细胞在补充了10%FBS和不同浓度的PI3K抑制剂(10-12M至10-5M,最终DMSO浓度0.2%)的RPMI(不含酚磺酞)中处理,用3μg/ml抗-人CD28抗体(BD Biosciences,San JoseCA)共刺激,并在95%空气和5%CO2的气氛下在37℃温育72h。根据生产商的说明书使用配对抗体定量ELISA试剂盒(分别来自Life Technologies、Carlsbad CA和R&DSystems、Minneapolis MN)在上清液中测量人IL-6和IL-17。
使用Graph Pad Prism v.6(GraphPad Software,La Jolla CA)通过非线性回归分析从浓度-响应曲线确定IC50值。
本发明的化合物表现出就PI3K-δ亚基而言低于1μM的IC50。
