Abstract
甲苯哒唑为一种抗寄生虫药物,具有超过40年的安全使用史。最近甲苯哒唑被重新利用,用于成胶质细胞瘤治疗。甲苯哒唑存在三种多形体(polymorph),但现有药物的多形体相对含量不同,并且不同多形体的抗癌治疗相关性是未知的。作为口服药物,甲苯哒唑多形体C为优异的形式,并以有效浓度到达脑和脑肿瘤。通过将甲苯哒唑与P‑糖蛋白抑制剂组合进一步提高功效。甲苯哒唑也可以用于其他癌症的治疗,以及作为化疗防护剂。
Description
本发明根据由国立神经障碍与中风研究所(National Institute ofNeurological Disorders and Stroke)授予的R25NS065729以及来自美国国立卫生研究院(National Institutes of Health)的P30-CA006973、UL1-RR025005和1S10RR026824-01在政府支持下进行。政府在本发明中具有一定权利。
发明技术领域
本发明涉及药物学领域。特别地,本发明涉及癌症治疗剂。
发明背景
中枢神经系统(CNS)癌症难以治疗,因为大多数全身施用的治疗剂不能在颅内肿瘤中达到有效浓度(1)。这由血脑屏障(BBB)部分地解释。在CNS中,BBB沿着包括紧密连接(tight junctions)的所有毛细管存在,从而阻断大的和亲水性的分子传递至CNS组织。据估计,仅约2%的小分子药物能够有效地跨越BBB(2)。
甲苯哒唑(MBZ)已经安全地用作人类抗寄生虫药物超过四十多年,并且显示出针对颅内蠕虫感染的功效。我们最近在原位神经胶质瘤和成神经管细胞瘤啮齿动物模型中证明了MBZ的临床前功效(3,4)。MBZ显著降低肿瘤生长并改进携带脑肿瘤小鼠的存活率。基于这些结果,开始了用于新诊断的高级神经胶质瘤患者的具有MBZ剂量递增的I期临床试验(NCT01729260)。已经产生了支持MBZ的几种抗癌机制,包括微管蛋白结合、激酶抑制、抗血管生成和促凋亡的证据(3-8)。然而,MBZ的脑渗透和药代动力学的重要特征仍有待确定。这种理解对潜在地改进MBZ的临床使用是重要的。
MBZ为高度疏水性的,并且可以基于结晶条件形成三种不同的多形体(polymorph)(9)。多形体A、B和C(MBZ-A、MBZ-B和MBZ-C)在驱虫药(anthelmintic)应用中显示了在溶解度、毒性和治功效果方面的独特特征(10-12)。虽然三种多形体的抗肿瘤功效的差异尚未被研究,然而,该信息可能对未来的MBZ癌症治疗至关重要,因为药物制剂可能包含不同量或组合的各种多形体。进一步研究的另一个关键原因是,多形体C(在驱虫药使用中最有效的多形体)可以随时间转化成不太有效的多形体A,特别是在较高的温度和湿度下(13)。由于多形体仅以固体形式存在,并且MBZ仅为口服药物,研究不同多形体的相关抗肿瘤特性最好通过经由口服施用MBZ多形体确定动物模型中的生物可利用度和功效来完成。本领域对鉴定用于治疗癌症,特别是脑癌的更有效、更一致且更安全的治疗剂存在持续需求。

甲苯哒唑可以通过本领域已知的任何方法被制备。在一种方法中,对氯甲苯被用作起始材料。参见图8。通常对于纯化,在室温使用甲醇使多形体C结晶。甲苯哒唑商购可得。
在本研究中,我们证明MBZ可以以显著的浓度和高的脑与血浆比到达脑组织。在口服施用之后1小时与8小时之间,MBZ-C维持高于0.767μg/g(相当于2.7μM)的脑水平,其中C最大为2,016μg/g(相当于7.1μM)。这些值超过MBZ对VEGFR2激酶的体外IC50(4.3μM)和组织培养中的一系列神经胶质瘤和成神经管细胞瘤细胞系中的IC50(0.11-1μM)(3,4)。此外,MBZ-C成为最有效的多形体,达到0.82的AUC0-24h B/P比。这是令人鼓舞的,因为替莫唑胺(temozolomide),对于高级神经胶质瘤的标准治疗,被测量为在小鼠中具有0.408的B/P比,而在人类中具有0.2的脑脊液(CSF)/血浆比(21,22)。在我们的研究中,MBZ在GL261脑肿瘤和正常脑组织中的分布差异不显著。值得提及的是,与其他神经胶质瘤模型相似,GL261神经胶质瘤的后期生长(advanced growth)在肿瘤中产生大量的血液,并且充分的灌注对于消除血液中MBZ的污染是必需的。
在三种多形体中,仅为用MBZ-C测量的AUC0-24h的19%的非常低的血浆存在解释了MBZ-A在GL261神经胶质瘤模型中未显示出功效。MBZ-A的低生物可利用度和较差的抗肿瘤功效与先前对其在抗寄生虫应用方面表现不理想的报道一致(10,12)。相比之下,MBZ-B能够在血浆中达到MBZ-C的AUC0-24h的165%,同时通过在6h测量证明的,显示相似脑浓度。这可以解释MBZ-B在携带GL261神经胶质瘤的小鼠中的升高的毒性,因为与MBZ-C相比,抗脑肿瘤功效基本相同。因此,我们建议MBZ-C为脑肿瘤疗法中的更好选择。实际上,尽管我们不知道在我们先前研究中曾经是有效的Teva品牌的MBZ中多形体C的原始浓度(3),但是这些片剂可能由于在3年内在标准RT条件下转化为多形体A而可能已经损失其功效,因此由MBZ-C制成的片剂应该储存在较低的温度下(13)。
MBZ的小尺寸(295道尔顿)和亲脂性有利于脑渗透(2)。值得注意的是,迄今所测试的共有相似的物理性质的其他苯并咪唑,诸如阿苯哒唑(albendazole)、噻苯哒唑、氟苯哒唑、奥芬哒唑和芬苯哒唑,甚至在比MBZ更高的剂量也未能提高或仅略微提高携带GL261神经胶质瘤的小鼠的存活率(补充图1)(3)。正如我们先前所观察到的,饲料中的芬苯哒唑使无胸腺裸鼠对成神经管细胞瘤细胞系的植入物的摄取受损(3),通过在植入之后5天管饲,其仅在GL261神经胶质瘤模型中产生非常少量且统计学上不显著的存活率的提高。存在可能促成多种苯并咪唑的脑肿瘤治疗的鲜明差异的几个因素。对于MBZ多形体A显示的一种因素,可能由于不良吸收而导致的低生物可利用度,可能对这类药物的治疗性能是不利的。其次,这些苯并咪唑的脑渗透尚未被充分研究,并且对于任何显著的治疗效果可能是不足的。此外,虽然在最近的报道中,MBZ已经牵涉抑制多种酪氨酸激酶,而阿苯哒唑显示缺乏此类能力,表明苯并咪唑间的抗肿瘤机制的差异(4,7,8)。
P-糖蛋白(P-gp,ABCB1)为ATP结合盒(ABC)转运蛋白,并且在限制药物摄取到脑中起重要作用(23)。依克立达为P-gp外排转运蛋白的第三代抑制剂,并且还抑制乳腺癌耐药蛋白(BCRP,ABCG2),即,BBB中的另一种关键外排转运蛋白(24)。先前的研究证明,啮齿动物中依克立达的共施用已经显著地多倍增加了许多癌症药物,诸如舒尼替尼(sunitinib)、帕唑帕尼(pazopanib)、埃罗替尼(erlotinib)和克唑替尼(crizotinib)的脑分布,这些药物在体外和动物研究中被确定为P-gp和ABCG2的底物(25-28)。此外,在I期临床试验中已经发现依克立达为安全的(19)。在本研究中,我们研究了依克立达与可能增强其功效的MBZ的组合。我们发现该组合大大改进了两种原位脑肿瘤模型的存活率。然而,在这项有限的研究中,MBZ的B/P比例和脑AUC0-8h未伴随依克立达的共施用而显示统计学上显著的差异,尽管其有能力显著增加携带脑癌的小鼠的存活率。当分析代谢物时,啮齿动物和人类中的两种主要代谢物之一,MBZ-NH2(20),由于共施用依克立达在B/P比(2.5倍)和AUC0-8h(2.4倍)方面显著提高。还值得注意的是,我们发现与正常脑组织相比MBZ-NH2优先地在GL261脑肿瘤中积累。尽管这些数据可能表明,MBZ-NH2是P-gp和/或ABCG2的可能底物,但这一发现的意义在这时尚不清楚。MBZ-NH2可能具有直接的细胞毒性作用似乎不太可能,因为进一步的测试仅显示对培养的GL261细胞的极小的细胞毒性。然而,MBZ-NH2通过在酸性肿瘤环境中优先积累而增加毒性不能被排除,并且需要进一步的研究。进一步的研究包括研究MBZ和依克立达的相互作用,特别是外排转运蛋白的潜在底物谱与MBZ的相互作用,以便更好地理解与MBZ的组合并从而对其进行改进。
MBZ-C为脑肿瘤治疗中最有效的多形体。MBZ-C与依克立达(一种P-糖蛋白抑制剂)的组合可以大大改进功效。该组合可以用于治疗,尤其是,高级神经胶质瘤和/或成神经管细胞瘤。该组合可以作为治疗方案的一部分共施用或单独施用。

细胞系和组织培养物
用于本研究的细胞系:小鼠神经胶质瘤细胞系GL261和人类成神经管细胞瘤异种移植物D425Med(D425)如先前描述获得(3,14)。将GL261和D425细胞在包含5%CO2的加湿空气中在37℃维持在补充有10%胎牛血清和抗生素的DMEM培养基中。之前描述了表达萤火虫萤光素酶的GL261-luc细胞(3)。
MBZ多形体的红外光谱
使用Direct DetectTM红外(IR)光谱仪(Millipore,Billerica,MA,USA)。先将MBZ粉末或研磨为粉末的MBZ片剂与水混合,遵循制造商的说明应用于卡片并空气干燥。如之前描述得分析并比较–C=O和–NH的光谱(9)。
颅内小鼠模型
所有动物研究都被约翰霍普金斯大学(Johns Hopkins University)动物保护和使用委员会(Animal Care and Use Committee)(ACUC)批准。GL261-luc在小鼠脑的额叶和D425细胞在小鼠脑的小脑的颅内植入遵循之前描述的程序(3,4)。在肿瘤植入之后5天,对小鼠每周5天管饲以50mg/kg的MBZ或其他苯并咪唑。通过将粉末与PBS和芝麻油(1:1,v:v)(Sigma)混合或通过将片剂研磨为粉末并重悬于以上提及的PBS/芝麻油混合物中来准备MBZ和其他苯并咪唑。类似于之前描述的,将依克立达准备为10mg/ml在0.5%羟丙基甲基纤维素和0.5%Tween 80的PBS中的悬浮液(15)。
MBZ药代动力学研究
5-6周龄的雌性C57BL6小鼠从NCI购买。动物实验根据批准的IACUC方案执行,并符合当地和国家指导方针。将所有MBZ多形体和片剂都以50mg/kg的剂量通过口服管饲施用。将依克立达在施用MBZ-C之前2小时以50mg/kg通过口服管饲施用。先将小鼠(3只动物/时间点)经由腹膜内注射60μl储备溶液进行麻醉,所述储备溶液在无菌0.9%NaCl溶液中包含盐酸氯胺酮(75mg/kg)(100mg/ml;盐酸氯胺酮(ketamine HCl;Abbot Laboratories,Chicago,IL,USA)和赛拉嗪(7.5mg/kg)(100mg/ml;Phoenix Pharmaceutical,St.Joseph,MO,USA)。然后通过从左心室穿刺和吸液(aspiring)取得血液样品。将血液样品与5mM EDTA混合,并以10000g离心5分钟,以获得用于进一步分析的血浆。
对于脑分布研究,在麻醉下通过使用20号针(20gauge needle)缓慢注射到左心室对小鼠灌注补充有20μl 0.02%肝素的20ml冰冷盐水。将右心房切开,然后允许血液流出。黄色的肾指示好的灌注质量,好的灌注质量对消除脑组织中的血液是必需的。在携带GL261肿瘤的小鼠中,通过容易识别的颜色和色度(shade)差异,将GL261肿瘤与正常脑区分开。将GL261肿瘤用解剖刀分离,并且将正常脑组织从对侧半球切下。将所有脑样品都称重并在处理前储存于-80℃。
MBZ施用之后随时间的变化(as a function of time)获取血液、脑和脑肿瘤组织。为了比较MBZ多形体的药代动力学,对三个列队的小鼠各自通过口服管饲施用50mg/kg的单一剂量。对于初步比较研究,在MBZ施用之后在1小时、2.5小时、4小时、6小时、8小时、15小时和24小时时获得血浆样品,而仅在6小时时收集脑组织。对于伴随或不伴随ELD的多形体C的比较研究,在MBZ施用之后2.5小时、4小时和8小时时获取血浆和脑组织样品。还获取对于单独的多形体C的脑肿瘤组织样品。
MBZ和代谢物的测量
定量血浆、脑和脑肿瘤组织中的MBZ及两种代谢物2-氨基-5-苯甲酰基-苯并咪唑(MBZ-NH2,CAS 52329-60-9)和外消旋二氢甲苯哒唑(MBZ-OH,CAS 60254-95-7)。以200mg/ml的浓度在血浆中制备组织匀浆,然后提取。用0.1ml包含0.5μg/ml内标A620223.69的甲醇从50μl血浆或组织匀浆提取甲苯哒唑及代谢物。在离心之后,将上清液(60μl)与水(40μl)混合,并然后转移到自动进样小瓶中。在室温用Atlantis dC18(2.1×100mm,3μm)柱用包含0.1%甲酸的甲醇/水流动相(60:40,v:v)使用0.25ml/min的等度流速持续5分钟实现分离。使用AB Sciextriple quadrapoleTM 5500质谱检测器(Applied Biosystems,Foster City,CA,USA)使用以正离子模式(positive mode)运行的电喷雾电离来监测分析物。将光谱仪编程为允许MBZ、MBZ-NH2、MBZ-OH、和A620223.69的[MH+]离子分别以m/z 296.0、238.0、298.0、和287.2穿过第一个四极杆(Q1)并进入碰撞池(Q2)。监测通过第三个四极杆(Q3)的MBZ(m/z 263.9)、MBZ-NH2(m/z 105.1)、MBZ-OH(m/z266.0)和A620223.69(m/z 124.1)的子代离子。通过使用二次方程式以1/x加权函数对稀释度多达1:100(v:v)的5ng/ml至500ng/ml(MBZ)和1ng/ml至500ng/ml(代谢物)的范围使用相对于内标的面积比峰值的分析来计算MBZ的校准曲线。如果一个或更多个浓度低于定量限值,则将药物动力学计算值指定为定量限值的1/2的值。如果连续两个时间点低于定量限值,则将后一个从分析中排除。
对于MBZ及其代谢物两者计算在每一个时间点的平均血浆和脑浓度。1.045g/ml用作啮齿动物脑组织的平均湿密度(16)。如在 第6.3版(PharsightCorp.,Mountain View,CA)中分析的,使用非房室模型法(noncompartmental method)从平均MBZ及其代谢物浓度-时间数据计算药代动力学参数。C最大和T最大为来自平均浓度数据的观察值。使用对数线性梯形方法(log-linear trapezoidal method)计算AUC最后。由浓度-时间曲线的终末阶段的斜率确定λz。终末半衰期(T1/2)通过将0.693除以λz来确定。如果λz的r2为<0.9,则不报告T1/2。使用AUC最后:代谢物AUC最后/MBZ AUC最后计算MBZ的相对系统暴露。使用AUC最后:脑或脑肿瘤AUC最后/血浆AUC最后计算与血浆相比在脑或脑肿瘤中的相对系统暴露。
统计分析
通过GraphPad Prism 5.0分析动物存活率数据。通过Mantel-Cox检验确定p-值。低于0.05的p-值被接受为统计学显著的。
对于将多形体或与ELD一起的施用进行比较的药代动力学研究,在给出在每一个时间点的平均浓度的计算方差的情况下,使用Bailer方法估计AUC最后的方差(17)。这然后是使用Z检验的成对比较,以确定由AUC最后表示的MBZ暴露之间是否存在显著差异(18)。使用非参数Wilcoxon符号秩检验进行个体数据的比较,使用All Pairs Tukey-Kramer检验进行事后分析。显著水平为P<0.05。
实施例2
多形体C对治疗小鼠中的脑肿瘤最有效
通过将几种商购可得的片剂(Janssen、Medley和Teva)以及两种定制的片剂(Aurochem S2015,其使用通常具有混合多形体的通用API;和S2017,其被指定为纯MBZ-C)的IR光谱与单独的MBZ进行比较,我们检验了这些片剂的多形体含量(图1A和B)。基于–C=O和-NH键的IR峰值,我们确定了Janssen和Medley片剂以及Aurochem S2017主要由MBZ-C制成。已经在RT储存了2年的Aurochem S2015和Teva片剂大体上显示MBZ-A的光谱。作为对照,将多形体A、B和C溶解于DMSO中,并单独地与GL261神经胶质瘤细胞孵育,其显示等同的细胞毒性(数据未示出)。
MBZ-A似乎对治疗携带颅内GL261神经胶质瘤的小鼠无效,而MBZ-C显示出最佳功效(图1C)。尽管MBZ-B显示与MBZ-C相似的存活率,但它在6只处理的小鼠中引起更多的毒性,伴随1例治疗相关的死亡(图1C)。功效数据在以下意义上恰当地反映了MBZ片剂的多形体组成:S2015无效,而MBZ-C制成的其他片剂都显示了显著功效,将对照组的29天平均存活期延长至42-45天(图1E)。
实施例3
MBZ以显著水平到达脑
在口服给药50mg/kg之后,MBZ-C达到16,039h*ng/ml的血浆AUC0-24h(图2A和表1A)。相比之下,MBZ-B达到26,474h*ng/ml的血浆AUC0-24h,而MBZ-A血浆AUC0-24h仅达到3,052h*ng/ml,目前在所有三种多形体中最低(对于AUC0-24h,P<0.05,其中MBZ-B>MBZ-C>MBZ-A;表1A)。彻底灌注之后的脑组织的测量显示MBZ-C跨越一段时间过程显著存在,与血浆MBZ水平密切相关,其中脑/血浆(B/P)比在8小时期间保持相对稳定为平均0.75(图2B-2C)。在口服管饲之后6h时比较多形体,我们发现MBZ-C和MBZ-B达到相似的脑水平,尽管在血浆中MBZ-B有较高的水平和AUC0-24h(图2D和图6,表1A),导致MBZ-C的平均B/P比比MBZ-B略微更有利(C为0.80,对比,B为0.64,以及A为0.29,p=0.055)(图2E)。这充分证实了图1C中的功效数据,其中MBZ-B和MBZ-C在GL261模型中显示出相似的存活率益处(平均存活期:MBZ-B 45天对比MBZ-C 48.5天)。然而,值得注意的是,MBZ-B显示更大的毒性,导致六只被治疗的动物中一只小鼠的早期死亡(图2D)。GL261脑肿瘤和对侧脑组织的分析指示MBZ-C在脑肿瘤和正常脑组织中的同等分布(图2D)。
实施例4
MBZ代谢物的药代动力学
我们确定了MBZ多形体的主要代谢物MBZ-NH2和MBZ-OH的血浆水平(对于MBZ-NH2的AUC0-24h,P<0.05,其中MBZ-B>MBZ-C>MBZ-A;对于MBZ-OH的AUC0-24h,P<0.05,其中MBZ-B与MBZ-C>MBZ-A;Table1A)。血浆和脑中MBZ-C代谢物的水平大体遵循MBZ-C浓度的相同模式(图3A和B)。MBZ-NH2在血浆中显示出比MBZ-OH高的水平(图3A),其中AUC0-24h与MBZ-OH的5,781h*ng/ml相比为10,516h*ng/ml(表1A)。明显地,以相反的模式,在C最大和AUC0-24h方面,测量到MBZ-NH2在脑中的水平比MBZ-OH低得多(图3B和表1A)。有趣地,在GL261神经胶质瘤中,MBZ-NH2达到比对侧脑中的显著更高的水平(图3C)。为了阐明MBZ代谢物的抗肿瘤作用,我们比较了GL261细胞中MBZ、MBZ-OH和MBZ-NH2的IC50,并确定了MBZ-NH2为MBZ的体外细胞毒性最小的衍生物(图3D)。

在肿瘤和周围脑组织中达到足够的治疗浓度为几乎所有脑癌治疗所面临的关键挑战。口服施用之后4小时,我们发现MBZ-C脑浓度以2,016ng/g(相当于7.1μM)达到峰值(表1A),这远高于培养的神经胶质瘤和成神经管细胞瘤细胞的IC50(0.11-1μM),并且也高于MBZ对VEGFR2激酶的4.3μM的体外抑制IC50。相对高的脑浓度可能有助于解释脑肿瘤模型中的MBZ功效。然后,我们推测,MBZ的脑分布的进一步增加将是期望的,因为它可以增加治疗功效。除了纯机械屏障以外,BBB采用主动外排机制来限制药物进入,诸如P-糖蛋白(P-gp)。依克立达(ELD)为抑制P-gp以及乳腺癌耐药蛋白(BCRP)的有效的第三代抑制剂,并且依克立达的共施用已经增加了几种药物的脑渗透(15,19)。我们首先检查了依克立达在GL261小鼠神经胶质瘤细胞中的细胞毒性,并确定其IC50为5.8μM(图4A)。将依克立达与0.25μM MBZ组合仅极小地增加体外细胞毒性(图4B)。在MBZ-C之前两小时,口服施用50mg/kg依克立达就AUC0-8h来看未显著改变MBZ的脑浓度,同时2.5h、4h和8h的B/P比平均值从0.75轻微升高到1.03,然而,这是统计学上不显著的(表1B和图4C)。有趣地,这伴随着MBZ-NH2的显著增加,并且当用依克立达和MBZ-C组合治疗时脑中B/P比从0.12提高至0.30(表1B)。
实施例6
与依克立达组合改进MBZ的治疗
依克立达和MBZ的联合疗法增加了GL261同系神经胶质瘤和D425异种移植物成神经管细胞瘤模型的存活率受益(图5)。这通过将7天或14天的50mg/kg依克立达治疗添加至50mg/kg的标准MBZ(MBZ-C)方案来实现。具体地,在GL261中,取决于治疗长度,联合疗法将生存中值提高到92.5天和110.5天,这是从单独的MBZ的53天以及29.5天(对照)和34天(单独的依克立达)的显着增加(图5B)。类似地,在原位D425成神经管细胞瘤异种移植物模型中,依克立达与MBZ的组合将生存中值增加至77天(图5D)。这是对具有53天存活率的仅MBZ治疗和单独的依克立达的显著改进,单独的依克立达在该特定动物模型中显示9天的极小存活率受益。
尝试用依克立达和MBZ进行延长的治疗过程,然而增加的毒性诸如严重的体重损失和死亡率限制了这些研究(数据未示出)。
