本申请要求2002年12月20日递交的美国临时申请顺序号60/434912号和2003年10月30日递交的美国临时申请顺序号60/516151号的优先权。该优先申请的公开内容通过引用全文结合到本文中。
背景
本发明涉及抑制SDF-1趋化因子(也称作CXCL12趋化因子)或者I-TAC(也称作CXCL11)结合于趋化因子受体CCXCKR2的新化合物和药用组合物。这些化合物用于预防肿瘤细胞增殖、肿瘤形成和肿瘤转移。
趋化因子属于小的细胞因子样蛋白超家族,其诱导细胞骨架重排牢固地贴附于上皮细胞和定向迁移,并且也影响细胞激活和增殖。趋化因子以与细胞表面蛋白特异性寻靶导引细胞的各种亚单位至特异性解剖位点一致的方式起作用。
多个小组的早期研究努力已指明趋化因子受体CXCR4在肿瘤转移和肿瘤生长中的作用。Muller等“Involvement of ChemokineReceptors in Breast Cancer Metastasis”,Nature,410:50-56(2001)证实乳腺癌细胞采用趋化因子介导的机制,例如那些肿瘤转移过程中调节白细胞运输的机制。肿瘤细胞表达独特的、非随机的功能活性趋化因子受体模式。通过CXCR4的信号传导介导乳腺癌细胞中的肌动蛋白聚合作用和苔癣形成,并且诱导趋化反应和侵袭反应。另外,表示乳腺癌转移的主要位点的器官(例如淋巴结、骨髓和肺)为CXCR4受体的配体的主要丰富来源。
采用免疫缺陷小鼠,Muller及同事通过用已知结合于CXCR4的抗体处理,成功减少注射人乳腺癌细胞的转移。他们的发现提示通过用CXCR4拮抗剂治疗患者可减少乳腺癌转移。
Bertolini等,“CXCR4 Neutralization,a Novel TherapeuticApproach for Non-Hodgkin’s Lymphoma”,Cancer Research,62:3106-3112(2002)证实注射抗-CXCR4抗体处理的人淋巴细胞减少肿瘤体积以及延长免疫缺陷小鼠的生存期。他们解释他们的发现意味着通过用CXCR4拮抗剂治疗患者可减少肿瘤体积。
最近的研究提示另一种趋化因子受体CCXCKR2在治疗癌症中也可为潜在的候选者。CCXCKR2优先表达在转化细胞中而不是正常细胞,在多种人癌症中可检测出表达。体外研究指明通过CCXCKR2拮抗剂可抑制CCXCKR2表达的细胞的增殖。小鼠体内研究指明CCXCKR2拮抗剂可抑制肿瘤形成和肿瘤生长。
通过Bertolini及同事观察到的肿瘤体积减少的另一种解释阐明了CCXCKR2的潜在重要性。这种减少明显是抗体介导的清除的结果,并且不是如早先相信的抗-CXCR4抗体的结果。在抗体介导的清除中,识别淋巴细胞的细胞表面蛋白的任何抗体应具有如抗-CXCR4抗体贡献的那样相同的作用。不幸地,Bertolini及同事的研究不确定所观察到的肿瘤应答是由于抗体介导的清除还是与CXCR4的相互作用。
然而,目前已知Bertolini及同事使用的淋巴癌细胞表达CXCR4和CCXCKR2两者。SDF-1为CXCR4的唯一配体。SDF-1和I-TAC两者结合CCXCKR2。采用抗-SDF-1抗体,目前已显示CCXCKR2拮抗剂担负着肿瘤载荷的减少和增加存活率。由于SDF-1为CXCR4的唯一配体,人们应期待SDF-1与抗-SDF-1抗体的中和等价于CXCR4与抗-CXCR4抗体的中和。然而,采用抗-SDF-1抗体的实验证实仅部分减少肿瘤载荷和增加存活率。这导致人们相信CCXCKR2是实际的靶标,因为持续的活性可能是由于第二种配体I-TAC与CCXCKR2相互作用的结果。
直到最近,肿瘤细胞增殖、肿瘤生长和肿瘤转移中CCXCKR2的可能重要性是未知的。目前,借助于指明某些CCXCKR2拮抗剂预防癌症的生长和扩散的能力的最近事实和指明CCXCKR2受体的有限的组织分布的表达模式,对提供能够特异性结合于肿瘤细胞上CCXCKR2受体而只有潜在的极少的副作用的化合物是有益的。
概述
本发明涉及新的化合物和含有结合于CCXCKR2受体的小分子调节剂的组合物。通常新化合物具有以下结构(I):
其中R3、R4、R5和R6、Y、Z、m和n如下定义。
在一个实施方案中,新化合物具有以下结构(II):
其中R3、R4、R5和R7以及Y如下定义。

在另一个实施方案中,抑制癌症的方法被公开。
以下将更详细地讨论这些和其它的实施方案。

在用本发明调节剂治疗癌症中,拮抗剂的合适的剂量水平通常在每天每kg患者体重约0.01-500mg,其可以单或多剂量给药。优选地,剂量水平为约0.1-250mg/kg每天,更优选为约0.5-100mg/kg每天。合适的剂量水平可为约0.01-250mg/kg每天,约0.05-100mg/kg每天,或约0.1-50mg/kg每天。在这个范围内剂量可为0.05-0.5、0.5-5或5-50mg/kg每天。
对于口服给药,组合物优选以包含1.0-1000mg的活性成分,具体为1.0、5.0、10.0、15.0、20.0、25.0、50.0、75.0、100.0、150.0、200.0、250.0、300.0、400.0、500.0、600.0、750.0、800.0、900.0和1000.0mg的活性成分的调节全身症状的剂量的片剂的形式提供给待治疗的患者。化合物可以以包括每天1-4次剂量,优选为每天1或2次的方案给药。

实验
为证实以上描述的化合物为SDF-1和I-TAC趋化因子的有用的调节剂,体外筛选化合物以测定它们在多种浓度下替代SDF-1和/或I-TAC与CCXCKR2受体结合的能力。如在Determination of IC50 values,Reagents and Cells中详细描述的(参见以下),在125I-标记的趋化因子存在下,化合物与乳腺细胞表达的CCXCKR2受体结合。然后用筛选方法测定化合物在多种浓度下替代标记的趋化因子与CCXCKR2受体位点结合的能力。
被认为是有效的调节剂的化合物在或低于1.1微摩尔(μM)和更优选在或低于300纳摩尔(nM)的浓度下能够替代至少50%趋化因子SDF-1或I-TAC与CCXCKR2受体的结合。目前,尤其优选的化合物在或低于200纳摩尔的浓度下能够替代至少50%的SDF-1或I-TAC与CCXCKR2受体的结合。满足这些标准的举例说明的化合物列于以下表1中。
表1
IC50值的测定
试剂和细胞。125I-标记的SDF-1购自Perkin-Elmer Life Sciences公司(Boston,MA)。MCF-7(腺癌,乳腺)细胞系得自美国典型培养物保藏中心(American Type Culture Collection)(Manassas,VA),并于37℃下,在5%CO2/空气混合物的湿润温育器中,在用10%小牛血清(FBS)(HyClone Logan,UT)和牛胰岛素(0.01mg/mL)(Sigma,St.Louis,MO)补充的DMEM(Mediatech,Hemdon,VA)中培养。
结合分析。测试目标化合物以测定它们与MCF-7细胞上CCXCKR2位点的结合能力。采用如在Dairaghi DJ等,HHV8-encodedvMIP-I selectively engages chemokine receptor CCR5.Agonist andantagonist profiles of viral chemokines.,J.Biol.Chem.1999 Jul 30;274(31):21569-74和Gosling J等,Cutting edge:identification of a novelchemokine receptor that binds dendritic cell-and T cell-active chemokinesincluding ELC,SLC,and TECK.,J.Immunol.2000 Mar 15;164(6):2851-6中描述的过滤方法,使用效力最大的放射配体结合。
在这些试验中,MCF-7细胞与目标化合物相互结合并且采用在Dairaghi和Gosling中描述的方法,评价这些化合物置换放射性标记的SDF-1的能力。把目标化合物加入到板上以达到指定浓度,然后在下面的结合培养基(25mM HEPES,140mMNaCl,1mM CaCl2,5mM MgCl2和0.2%牛血清白蛋白,调至pH 7.1)中,通过加入放射标记的趋化因子(125I SDF-1)于4℃用细胞温育3小时。然后,伴随温和的搅拌下,于4℃将所有试验物温育3小时。所有结合试验物温育后,采用细胞收获器(Packard)在PEI处理的GF/B玻璃滤膜上涡旋反应液并冲洗两次(25mM HEPES,500mM NaCl,1mM CaCl2,5mM MgCl2,调至pH 7.1)。混合闪烁剂(MicroScint 10,Packard)被加入到孔中,并且在Packard Topcount Scintillation counter上对滤膜计数。分析数据并采用Prism(Macintosh的GraphPad Prism 3.0a版,GraphPad软件,www.graphpad.com)绘图。
体外细胞增殖的抑制
小分子量化合物对乳腺癌上表达的CCXCKR2的拮抗作用体外抑制细胞增殖。与未治疗对照组比较,体外处理的细胞在一定时间内呈现减少的细胞生长。
体外细胞粘附的抑制作用
体外静止黏附试验被用于建立白细胞迁移活动的模型,包括细胞粘附和随后浸润到给定的组织中。单层的血管内皮细胞在表面上生长,并且用荧光染料标记表达CCXCKR2的细胞以便能够可视化。实验显示,与其中没有表达CCXCKR2的对照组相比较,粘附于内皮层的表达CCXCKR2的细胞的存在促进另外表达CCXCKR2的细胞的粘附。另外,与媒介物处理的对照组相比较,加入CCXCKR2调节剂抑制粘附。
体内肿瘤形成的抑制作用
用表达CCXCKR2的人B细胞淋巴癌细胞注射给予免疫缺陷小鼠。用能抑制血管化肿瘤形成的CCXCKR2调节剂治疗那些小鼠。在一项研究中,用CCXCKR2拮抗剂治疗的17只小鼠中只有1只发展成囊化的、血管化的肿瘤,而媒介物空白对照组中的17只小鼠中11只发展成囊化的、血管化的肿瘤。
体内肿瘤体积的减少
用人乳腺癌注射给予免疫缺陷小鼠。每周测量肿瘤三次并测定肿瘤体积。与媒介物对照组治疗的小鼠比较,用CCXCKR2调节剂治疗小鼠呈现减少的肿瘤体积。
有机化学领域的任何普通技术人员应从所提供的说明书、图和实施例意识到对本发明的优选的实施方案可做出改进和变化而不违背通过下面的权利要求和它们的等价物定义的本发明的范围。
