Description
技术领域
本申请涉及一种作为选择性的PI3Kδ激酶抑制剂的化合物、以及使用这样的化合物抑制PI3Kδ激酶活性的方法和用途。
背景技术
磷脂酰肌醇3-激酶(PI3K)是一种脂激酶家族成员,是PI3K/AKT/mTOR信号通路的重要组成部分,能够介导体内的磷酸化过程,从而影响细胞的生长、增殖、分化、迁移、凋亡等一系列过程。研究发现,PI3K通路的异常激活与多种疾病的发生发展密切相关,不同类型的PI3K发挥着不同的功能。PI3K家族I型激酶主要包括PI3Kα、PI3Kβ、PI3Kγ和PI3Kδ。其中PI3Kα的突变与肿瘤的发生发展有关;PI3Kβ能够激活血小板,与血栓性疾病的发展有关,并且在PTEN缺失的肿瘤中,PI3Kβ会促进肿瘤的恶变;PI3Kγ和PI3Kδ主要与免疫系统和造血系统有关,与免疫、血液肿瘤以及炎症的发生密切有关。PI3Kδ是PI3K的一种亚型,主要存在于白细胞中。近年来,选择PI3Kδ为靶点,开发选择性PI3Kδ抑制剂,可治疗与B细胞相关的淋巴瘤、血液肿瘤。已有研究表明,抑制PI3Kδ对治疗血液肿瘤有效,因此PI3Kδ激酶成为治疗血液肿瘤的靶点,如:慢性淋巴细胞白血病(CLL)、非霍奇金淋巴瘤(NHL)、霍奇金淋巴瘤(HL)、套细胞淋巴瘤(MCL)等。此外,PI3Kδ是B细胞发育中非常关键的蛋白,阻断PI3Kδ功能,就能影响B细胞的功能(Vivanco和Sawyers,Nature Reviews Cancer,2002,vol.2,issue7,489-501)。近年来研究表明,PI3Kδ的突变与诱发性呼吸道感染、损伤有关,而且有研究证实抑制PI3Kδ对治疗实验性关节炎有效,提示PI3Kδ可能是治疗自身免疫性疾病的一个靶点。因此,抑制PI3Kδ将在类风湿性关节炎(RA)、系统性红斑狼疮(SLE)和哮喘等相关的自身免疫性疾病的治疗中发挥作用(J.Immunol.,2007,178,2328-2335;Blood,2006,vol.107,issue 2,642-650)。PI3K抑制剂预期经由其在调节与呼吸道疾病,诸如哮喘、COPD和囊性纤维化关联的T-细胞介导的炎症反应中的作用提供治疗益处(J.Biol.Chem.,2005,vol.280,issue 44,36952)。
本发明人经过实验,发现了一种选择性的PI3Kδ激酶抑制剂,以及使用该激酶抑制剂抑制PI3Kδ激酶活性的方法和用途。

实施例83:体外抑制活性(酶活)测定
体外酶活实验测定化合物对PI3K家族Ⅰ型激酶(PI3Kα、PI3Kβ、PI3Kγ、PI3Kδ)、Ⅱ型激酶(PIK3C2A、PIK3C2B)的IC50值。蛋白激酶PI3Kα、PI3Kγ、PI3Kδ、PIK3C2A、PIK3C2B均购自Invitrogen(美国);蛋白激酶PI3Kβ购自sigma(美国);三种底物PIP2:PS、PI和PI:PS均购自Invitrogen(美国)。
分别取稀释至一定浓度的蛋白激酶PI3Kα5.4μL(终浓度为0.16ng/μL)、PI3Kβ5.4μL(终浓度为6ng/μL)、PI3Kδ5.4μL(终浓度为1ng/μL)、PI3Kγ5.4μL(终浓度为5ng/μL)、PIK3C2A 5.4μL(终浓度为5ng/μL)、PIK3C2B 5.4μL(终浓度为10ng/μL),分别与梯度稀释的药物化合物各1μL室温反应1小时(药物终浓度分别为10μM、1μM、0.3μM、0.1μM、0.03μM、0.01μM、0.003μM、0.001μM)。
向上述PI3K家族Ⅰ型激酶各反应管中加入ATP(Promega,美国)和底物PIP2:PS混合物共6μL(激酶PI3Kα、PI3Kβ反应体系中ATP终浓度为10μM,激酶PI3Kδ、PI3Kγ反应体系中ATP终浓度为50μM,底物PIP2:PS终浓度均为50μM),37℃反应1小时。反应缓冲液为50mMHepes(pH 7.5)(Promega,美国)、3mM MgCl2、1mM EGTA(Promega,美国)、100mM NaCl、0.03%CHAPS(Promega,美国)。
向上述PI3K家族Ⅱ型激酶各反应管中加入ATP和底物PI混合物共6μL(终浓度分别为50μM和100μM),37℃反应1小时。反应缓冲液为50mM Hepes(pH 7.5)、3mM MgCl2、1mMEGTA、100mM NaCl、0.03%CHAPS。
取5μL反应后的激酶溶液置于384孔板(Corning,美国)中,加入5μL ADP-GloTM试剂(Promega,美国),室温反应40分钟以终止激酶反应并消耗完剩余的ATP;加入10μL激酶检测试剂将ADP转化成ATP,使用偶联的萤光素酶/萤光素反应检测新合成的ATP,利用Envision读数后作图,计算Graphpad IC50值,实验结果见表2和表3。
实验表明,本发明的化合物是PI3Kδ的选择性抑制剂,针对PI3Kδ具有很强的抑制活性,并且相对于其他PI3K家族激酶具有优异的选择性,特别是相对于PI3Kγ的抑制活性的选择性达到10倍以上,更优选达到20倍以上。PI3Kδ和PI3Kγ主要在淋巴细胞中表达,但是有文献报道PI3Kγ同时也在心肌细胞中表达,如果同时抑制PI3Kγ,会影响心脏功能,例如可能会影响到缺血性心脏病患者新生血管形成(Circ Res.2010March 5;106(4):757–768)。因此选择性地抑制PI3Kδ活性而不对PI3Kγ产生抑制作用或抑制作用相对较低,具有临床上的意义。与对照化合物TGR1202(MedChemExpress,中国)相比,本发明的化合物对PI3Kδ的活性提高了14倍,相对于PI3Kγ的选择性提高了38倍。

实施例84:大鼠类风湿性关节炎模型中药效检测
在本实施例中,测试化合物9在大鼠佐剂性关节炎模型中的实验结果。
实验步骤如下:
(1)从北京维通利华实验动物有限责任公司购买Sprague-Dawley(SD)大鼠,雌性,体重180g±20g,饲养于SPF级实验室中,饮水及垫料均经高压消毒无菌处理,有关小鼠的所有操作均在无菌条件下进行。
(2)溶媒组和给药组于第0天将10.0mg/ml CFA(完全弗氏佐剂,购自美国Sigma)充分混匀,于每只大鼠右后足跖皮内注射CFA 0.1ml致炎;正常组用生理盐水同法注射。
(3)造模后每3或4天进行1次体重和足爪肿胀度的测量。根据足爪肿胀度,于第20天全身炎症明显后将造模成功的雌性SD大鼠随机分为2组,每组5只,即溶媒组(0.5%甲基纤维素溶液,0.05ml/kg/天,购自中国国药)和化合物9给药组(25mg/kg/天剂量);正常组小鼠5只,每只给予生理盐水(0.05ml/kg/天)。各组口服灌胃给药,每天1次,用药14天。
(4)给药后每两天进行一次体重和足爪肿胀度的测量,用足爪肿胀仪测量足爪肿胀度。致炎前用足容积测量仪测量每个大鼠左后足(非致炎侧)容积,致炎后测量左后足容积,求出继发侧足爪肿胀度(Δml=︱注射后的足爪容积-注射前的足爪容积︱)。
实验结果如图1a、1b所示。化合物9在大鼠佐剂性关节炎模型中,对大鼠体重没有明显影响,如图1a所示。化合物9在给药14天后大鼠足爪肿胀度与溶媒组相比明显减轻,这说明本发明的化合物对类风湿性关节炎具有治疗作用。
