嘧啶化合物及其医药用途
技术领域
本发明涉及一种嘧啶化合物及其医药用途。
背景技术
Aurora A激酶是一种丝胺酸(serine)/苏胺酸(threonine)激酶,可调节有丝分裂进程(mitotic progression)、中心体成熟(centrosome maturation)及纺锤体组装(spindle assembly)。这种激酶在稳定MYC族致癌蛋白(oncoproteins)中起着重要作用,根据美国癌症基因体图谱计划(The Cancer Genome Atlas,TCGA),已经在28%的癌症中观察到其基因扩增(gene amplifications)。诱导Aurora A激酶的DFG环(DFG-loop)构造变化(conformational change)的小分子抑制剂可导致MYC族致癌蛋白降解,从而对癌症治疗具潜力。
已经鉴定出了包括化合物CD532在内的Aurora A激酶抑制剂。参见WO 2014/190207 A1。然而,CD532的体内疗效较弱。
因此,亟需开发有效抑制Aurora A激酶活性的新颖化合物。

口服给药的组合物可以是任何口服可接受的剂型,包括胶囊、片剂、乳剂及水性悬浮液、分散液及溶液。对于片剂来说,常用的载体包括乳糖及玉米淀粉。通常也添加诸如硬脂酸镁(magnesium stearate)的润滑剂。对于以胶囊形式的口服给药而言,有用的稀释剂包括乳糖及干燥的玉米淀粉。当口服给予水性悬浮液或乳剂时,可以将活性成分悬浮或溶解在与乳剂或悬浮剂结合的油相中。如果需要,可以添加某些甜味剂、调味剂或着色剂。口服固体剂型可以通过喷雾干燥技术来制备;热熔挤出策略、微粉化及纳米研磨技术。
可以依据药物制剂领域中已知的技术来制备鼻用气雾剂或吸入组合物。例如,可以使用本领域已知的苯甲醇(benzyl alcohol)或其他适合的防腐剂、提升生物利用度的吸收促进剂、碳氟化合物(fluorocarbons)及/或其他助溶剂或分散剂,将此种组合物制备为在盐水中的溶液。具有活性化合物的组合物也可以以栓剂(suppositories)的形式用于直肠给药。
医药组合物中的载体在与组合物的活性成分的兼容性上须为“可接受的”(且较佳能够稳定活性成分),并且对于治疗的主体无害。可以将一种或多种增溶剂用作药物赋形剂以传递活性化合物。其他载体的实例包括胶体氧化硅、硬脂酸镁、纤维素、硫酸月桂酯钠(sodium lauryl sulfate)以及D&C Yellow#10。
术语“治疗(treating)”是指将化合物施用于或给予主体,以治愈、缓解、减轻、改变、矫正(remedy)、改善、或影响疾病、症状、或其倾向(predisposition)。“有效量”是指赋予主体期望的效果所需的化合物的量。如本领域技术人员所知,有效量取决于给药途径、赋形剂用法、以及与其他治疗方法(诸如其他活性剂的使用)共同使用的可能性而变化。
无须进一步阐述,相信本领域的技术人员可基于以上描述最大程度地利用本发明。以下实施例被解释为仅是说明性的,而不以任何方式限制本揭露的其余部分。本发明所引用的所有出版物通过全文并入做为参考。

如下,使用NCI-H446-异种移植致瘤性小鼠模型确定两种式(I)化合物(即化合物71及化合物122)在抑制肿瘤生长方面的效果。
将6周龄的雄性无胸腺nu/nu裸鼠(BioLASCO)饲养在无菌笼中,该笼保持在12小时的明/暗循环下,并控制温度及湿度。小鼠皮下接种1×106NCI-H446细胞(

)悬浮在与50%Metrigel Matrix(Corning,美国)混合的盐水。用数位卡尺(GMC-190;Goldsun电子公司)测量异种移植肿瘤的尺寸,并使用以下算法计算:肿瘤体积(mm3)=长度×(宽度)2/2。每周至少测量体重及肿瘤尺寸两次。当异种移植肿瘤尺寸达到≥200mm3时,将化合物71、化合物122、对照化合物MLN8237(结构如下所示)及对照化合物LY3295668(结构亦如下所示)分别以100mg/kg的剂量及5-on-2-off的给药方案口服给予小鼠2至4周,用赋形剂处理的小鼠作为控制组。
Figure GDA0004237989360000531
如图2A及图2C所示,以100mg/kg的化合物71在10天内出乎意料地将小鼠的肿瘤尺寸实质上从约250mm3缩小到小于50mm3,并且在14天内从大于750mm3缩小到小于50mm3。这些结果表明化合物71出乎意料地诱导超过80%的肿瘤消退。
同样如图2A所示,化合物71出乎意料地表现出比对照化合物MCLN8237更高的疗效。尽管两种化合物都以100mg/kg的剂量在10天内将肿瘤尺寸从约250mm3缩小到小于50mm3,但在治疗停止后6周,与用化合物MCLN8237处理的小鼠的肿瘤尺寸相比,用化合物71治疗的小鼠的肿瘤尺寸仍小于50mm3,而MCLN8237增大至大于700mm3
图2B显示化合物122出乎意料地诱导超过80%的肿瘤消退,并且比对照化合物LY3295668具有更高的疗效。具体地,虽然100mg/kg的化合物122将肿瘤尺寸实质上从约250mm3缩小到小于50mm3,但是100mg/kg的化合物LY3295668却将肿瘤尺寸从约250mm3增大到大于350mm3
上述结果表明,式(I)化合物在抑制肿瘤生长方面具有出乎意料的高体内疗效。
实施例7:体内cMYC蛋白质含量降低及细胞凋亡诱导
如下,使用NCI-H446异种移植致瘤性小鼠模型评估式(I)化合物(即化合物71)在降低cMYC蛋白质含量及诱导细胞凋亡方面的疗效。
将6周龄的雄性无胸腺nu/nu裸鼠(BioLASCO)饲养在无菌笼中,该笼保持在12小时的光照/黑暗循环下,并控制温度及湿度。小鼠接种1×106NCI-H446细胞(
Figure GDA0004237989360000541
)悬浮在与50%Metrigel Matrix(Corning,美国)混合的盐水。用数位卡尺(GMC-190;Goldsun电子公司)测量异种移植肿瘤的尺寸,并使用以下算法计算:肿瘤体积(mm3)=长度×(宽度)2/2。每周至少测量体重及肿瘤大小两次。当异种移植肿瘤尺寸达到≥500mm3时,对异种移植瘤裸鼠口服(PO)给予化合物71,剂量为100mg/kg。给药后2小时、4小时、8小时及24小时取下肿瘤。对肿瘤的组织溶解产物进行西方墨点分析。使用的初级抗体为cMYC(细胞讯息传导,Cat No.5605S)、PARP-1(Abcam,ab32378)及β-ACTIN(Sigma-Aldrich,A1978)。
如下图3所示,化合物71显着诱导细胞凋亡,如在施用化合物71后24小时内,超过80%的异种移植肿瘤中分裂的PARP-1(cPARP-1)的量增加所表明。再者,在超过50%的异种移植肿瘤中,化合物71降低了cMYC蛋白质含量。
