相关申请的交叉引用
本申请要求2016年6月14日提交的美国临时专利申请第62/349,713号的优先权,其整体内容通过引用全部并入本文。
背景技术
循环肿瘤细胞(“CTC”)是血液基标记物,其被假设为在癌症检测和进展中具有预测价值和预后价值。具体而言,CTC理论上是来自原发性肿瘤和转移部位的肿瘤细胞的微创源。(Alix-Panabieres C等,Challenges in circulating tumour cell research,NatRev Cancer,2014年9月,14(9),623-31和Yap T等,Circulating tumor cells:amultifunctional biomarker,Clin Cancer Res,2014年5月15日,20(10),2553-68)。许多癌症类型已知或预测会产生CTC,包括多发性骨髓瘤。Paiva B等,Detailedcharacterization of multiple myeloma circulating tumor cells shows uniquephenotypic,cytogenetic,functional,and circadian distribution profile,Blood,2013年11月21日,122(22),3591-3598。此外,癌症干细胞(“CSC”)被预测为具有预后价值的另一种可能的癌细胞类型,理论上为CTC的亚群。Scatena R等,Circulating tumour cellsand cancer stem cells:a role for proteomics in defining theinterrelationships between function,phenotype and differentiation withpotential clinical applications,Biochim Biophys Acta,2013年4月;1835(2),129-143;Faltas B.Cornering metastases:therapeutic targeting of circulating tumorcells and stem cells,Front Oncol,2012年7月3日,(2)68。根据定义,CTC是有核的、CD45阴性、上皮细胞粘附分子(“EpCAM”)阳性和泛细胞角蛋白阳性细胞。然而,从全血中鉴定和分离CTC在技术上具有挑战性,因为CTC非常罕见并且可以低至7.5毫升(“mL”)血液中1个细胞(即数十亿个细胞中的1个)。
目前,对于CTC唯一接受和批准的指征是作为癌症进展的预后标志物的计数。系统(CellSearch是强生公司(Johnson&Johnson Corp)的注册商标)是目前唯一被FDA批准用于对CTC进行计数的化验。(Ignatiadas M等,Circulating tumor cellsand circulating tumor DNA for precision medicine:dream or reality?,Ann Oncol,2014年12月,25(12),2304-13和Toss A等,CTC enumeration and characterization:moving toward personalized medicine,Ann Transl Med,2014年12月,2(11):108,1-16.)。不幸的是,仅被批准用于转移性乳腺癌、结肠直肠癌和前列腺癌。(HayesDF等,Circulating tumor cells at each follow-up time point during therapy ofmetastatic breast cancer patients predict progression-free and overallsurvival,Clin Cancer Res,2006年7月15日,12(1),4218-24;Cristofanilli M等,Circulating tumor cells,disease progression,and survival in metastatic breastcancer,N Engl J Med,2004年8月19日,351(8),781-91;De Bono JS等,Circulatingtumor cells predict survival benefit from treatment in metastatic castration-resistant prostate cancer,Clin Cancer Res,2008年10月1日,14(19),6302-9;和CohenSJ等,Relationship of circulating tumor cells to tumor response,progression-free survival,and overall survival in patients with metastatic colorectalcancer,J Clin Oncol,2008年7月1日,26(19),3213-21)。
在当前定义下鉴定CTC仍然存在挑战。第一,由于EpCAM阳性循环上皮细胞,可能存在假阳性结果。第二,由于肿瘤细胞经历上皮-至-间充质转变导致上皮标志物的表达降低,可能发生假阴性结果。(Yu M等,Circulating breast tumor cells exhibit dynamicchanges in epithelial and mesenchymal composition,Science,2013Feb 1,339(6119),580-4)。第三,文献中越来越多的证据表明并非所有CTC表达EpCAM,并且某些癌症类型(例如肾癌)具有EpCAM的低表达或异质表达。(Eichelberg C等,Epithelial celladhesion molecule is an independent prognostic marker in clear cell renalcarcinoma,Int J Cancer,2013年6月15日,132(12),2948-55和Spizzo G等,EpCAMexpression in primary tumour tissues and metastases:an immunohistochemicalanalysis,J Clin Pathol,2011年5月,64(5):415-20)。因此,临床上需要使用广泛的肿瘤标志物的经济且稳健的化验,所述广泛的肿瘤标志物可以识别所有潜在的CTC而没有偏差。靶向癌症的烷基磷酸胆碱(“APC”)类似物提供了用于从大范围的不同癌症类型中鉴定和分离CTC的新方法。

具体实施方式
PLE类似物具有鉴定、分离所有类型的CTC以及实现所有类型的CTC的下游分析的能力。癌细胞的脂筏比健康细胞多5到10倍。脂筏是膜磷脂双层的特殊区域,含有高浓度的胆固醇和鞘脂类,并且用于组织细胞表面和细胞内信号传递分子(例如,生长因子和细胞因子受体,磷脂酰肌醇3-激酶(PI3K)/Akt存活途径)。数据表明,脂筏是PLE进入的门户。这些化合物对癌细胞与非癌细胞的显著选择性归因于PLE对胆固醇的高亲和力和癌细胞中丰富的含胆固醇的脂筏。由于脂筏结构的破坏抑制了PLE向癌细胞中的摄取,因此脂筏发挥的关键作用得到了强调。已经表明,当阻止脂筏形成时,PLE的摄取减少了60%。
在超过55种异种移植物和自发性肿瘤模型中获得的初步结果已普遍显示CLR1404在肿瘤中经历选择性摄取和延长的保留。Weichert,JP等,Alkylphosphocholine analogsfor broad-spectrum cancer imaging and therapy,Sci Transl Med,2014年6月11日,6(240ra75)。之前未知的是PLE类似物是否能够被CTC吸收到能够鉴定和分离CTC的程度。

提供以下实施例仅用于说明目的,并不意味着以任何方式限制本发明。
实施例
实施例1-PLE-磁珠结合物的合成
首先,式I-式IV的PLE和如本文所述的磁珠各自连接至其自身的官能团。然后通过点击化学将这些官能团连接。例如,本发明的式I的PLE可以与叠氮官能团连接,磁珠可以与炔官能团连接。然后叠氮官能团和炔官能团可以通过点击化学键合,例如铜催化叠氮-炔环加成(“CuAAC”)。通常,连接到官能团的磁珠被称为“官能化磁珠”,并且可以从多种来源获得,如Nanocs,Inc.。
CLR1401叠氮化物的合成
在反应容器中,将18-(对碘苯基)十八烷基磷酸胆碱(4.01g,6.3mmol)、叠氮化钠(818mg,12.6mmol)和抗坏血酸钠(140mg,0.71mmol)溶解在脱气乙醇(28ml)与水(12ml)的混合物中。将碘化亚铜(I)(120mg,0.63mmol)和N,N’-二甲基-乙二胺(0.1ml,0.94mmol)加入到反应混合物中。紧密关闭反应容器,将混合物在80℃下搅拌45分钟。将反应混合物冷却至室温,加入水(60ml),并将混合物在空气中搅拌30分钟。将混合物转移到分液漏斗中,加入氯仿(80ml)和甲醇(52ml),并通过摇动进行萃取。除去氯仿层,重复萃取(2×80ml氯仿)。用0.01N HCl洗涤合并的氯仿萃取物,用Na2SO4干燥,过滤并蒸发至干燥。将残余物溶于氯仿(4ml)中并在搅拌下缓慢加入丙酮(170ml)。将混合物搅拌30分钟并过滤。用丙酮在过滤器上冲洗产物,并在高真空下干燥,得到3.31g(95%)18-(对叠氮基苯基)十八烷基磷酸胆碱。
PLE-叠氮化物与炔官能化磁珠的键合
CLR1401叠氮化物通过点击化学与炔官能化磁珠键合。以上是CuAAC的一个实施例。在Himo F等,Copper(I)-catalyzed synthesis of azoles中描述了CuAAC。DFT研究预测了前所未有的反应和中间体,J Am Chem Soc,2005年1月12日,127(1),210-216,其通过引用整体并入。简而言之,在氧化铜(“Cu(I)”)催化剂存在下,将炔官能化磁珠和CLR1401叠氮化物在1:1比例的水和叔丁醇中混合6至12小时。任选地,将抗坏血酸钠加入混合物中。然后可以使用简单的过滤或萃取从溶液中分离最终的PLE-磁珠。
PLE-乙炔与叠氮官能化磁珠的键合
CLR1401乙炔通过点击化学与叠氮官能化磁珠键合。如上所述,可以使用用于键合CLR1401叠氮化物与炔官能化磁珠的相同CuAAC反应。
羧基-PLE与胺官能化磁性纳米颗粒的键合
羧基CLR1401通过酰胺键合与胺官能化磁性纳米颗粒键合。酰胺键合可以用任何适于形成酰胺键的偶联剂实现,例如用于肽合成的试剂,包括但不限于:(2-(1H-苯并三唑-1-基)-1,1,3,3-四甲基脲六氟磷酸盐)(“HBTU”)、(1-[双(二甲基氨基)亚甲基]-1H-1,2,3-三唑并[4,5-b]吡啶-3-氧化六氟磷酸盐)(“HATU”)、(COMU可从Sigma AldrichCo,LLC获得并且是Luxembourg Biotechnologies Ltd.的注册商标)和丙烷膦酸酐(“PPAA”或T3P可通过Euticals SPA获得并且是Euticals SPA的注册商标)。
PLE羧基-AZD与胺官能化磁性纳米颗粒的键合
作为上述酰胺键合的替代,胺官能化磁性纳米颗粒可以通过氮杂环丁酮(“AZD”)接头与羧基-PLE键合。例如,CLR1401羧基-AZD可以经由AZD接头与胺官能化磁性纳米颗粒键合。AZD连接在Roberts LR等,Kappa agonist CovX-Bodies,Bioorg Med Chem Lett,2012年6月15日,22(12),4173-4178和Sato S等,Chemically Programmed Antibodies ASHIV-1Attachment Inhibitors,ACS Med Chem Lett,2013年5月9日,4(5),460-465中有描述。
实施例2-使用荧光PLE类似物鉴定和计数肺癌、甲状腺癌、乳腺癌、宫颈癌、鳞状细
胞癌和结肠直肠癌患者的循环肿瘤细胞
方法
当可获得时,将来自7名患有肺癌(患者101和103)、甲状腺癌(患者102)、乳腺癌(患者106)、宫颈癌(患者104)、鳞状细胞癌(107)和结肠直肠癌(患者108)的癌症患者治疗之前(抽取1)和治疗之后(抽取2)的全血收集在Cell收集管或者乙二胺四乙酸(“EDTA”)收集管中。使用Ficoll-Paque密度梯度从全血中分离单核细胞。然后将来自每位患者的细胞与Fc阻断剂一起培养。然后用CD45、CD14、CD34、EpCAM和泛细胞角蛋白(CK)的荧光标记抗体和荧光PLE类似物(“CLR1501”)染色细胞30分钟。然后通过流式细胞术分析细胞以指示来自每个全血样品(其对于特定标记物是阳性和/或阴性的)细胞数量。根据目前的定义,CTC被鉴定为CD45-、CD14-、CD34-、CK+和EpCAM+的活细胞(“根据定义”)。由于先前CD14+单核细胞/巨噬细胞的经验(图1),由于CLR1501的高摄取,CD14+细胞从分析中除去。还从分析中除去CD34+正常上皮细胞。相比之下,相同患者中剩余的CD45+和CD34+细胞在很大程度上不会占用CLR1501。该分析的结果在下面解释并总结在表1和2中。
表1和表2的第一行描绘了来自每个患者的抽取血液满足CTC的定义:CD45-、CD14-、CD34-、CK+和EpCAM+并且包含细胞核的细胞的数量。第二行描绘了来自每位患者的抽取血液为CD45-、CD14-、CD34-、CK+并且包含细胞核的细胞的数量。第三行描绘了来自每位患者的抽取血液为CLR 1501+、CD45-、CD14-、CD34-、CK+并且包含细胞核的细胞的数量。第四行描绘了来自每位患者的抽取血液为CD45-、CD14-、CD34-和EpCAM+并且包含细胞核的细胞的数量。第五行描绘了来自每位患者的抽取血液为CLR1501+、CD45-、CD14-、CD34-和EpCAM+并且包含细胞核的细胞的数量。第六行描绘了来自每位患者的抽取血液为CLR 1501+、CD45-、CD14-、CD34-、CK-和EpCAM-并且包含细胞核的细胞的数量。
表1.在收集管中收集的具有不同癌症类型的患者的血液样品中的循环肿瘤细胞的鉴定和计数
M表示百万
表2.在EDTA收集管中收集的具有不同癌症类型的患者的血液样品中的循环肿瘤细胞的鉴定和计数
M表示百万
结果
所有七个样品含有可检测的CTC(根据定义),其示出CLR1501的正摄取(比较表1和表2中的第1行与第3、5和6行)。图1中示出了代表性的流式细胞术图像,其描绘了来自患者8的血液样品的CD14+细胞中CLR1501的高摄取。在图1中,左上象限表示CD14-/CLR1501+细胞,右上表示CD14+/CLR1501+,右下表示CD14+/CLR1501-,左下表示CD14-/CLR1501-。在组A中,从患者108抽取的血液中分离的对CD45和CD34阴性的细胞(即可能的循环肿瘤细胞)用除Brilliant Violet 785TM CD14之外的所有标记物染色示出。对CD14标记阳性的细胞示出在x轴上,对CLR1501阳性的细胞示出在y轴上。组A用作对照以设定Brilliant Violet785TM CD14阳性细胞的门限。在组B中,从患者108抽取的血液中分离的对CD45和CD34阴性的细胞用所有标记染色示出,包括Brilliant Violet 785TM CD14。如图所示,99.7%的对CD14+阳性的细胞对CLR1501也呈阳性。比较图1的组A与组B。
此外,在所有癌症类型中,不论使用哪种血液收集管,CLR 1501能够鉴定~99-100%的CK+细胞(比较表1或表2的第2行与第3行)和~35-100%的EpCAM+细胞(比较表1或表2的第4行或第5行)。令人惊讶的是,存在大量CLR1501+细胞,而无CK-、EpCAM-、CD45-、CD14-、CD34-细胞,并含有细胞核(第6行,表1-2)。表1和表2的第6行中指示的细胞不是血细胞类型,但可以是可能具有降低的EpCAM和CK表达或无EpCAM和CK表达的其它肿瘤细胞。据报道,许多癌症表达其它肿瘤标志物,具有EpCAM和/或CK的异质表达,或者可能正在经历上皮-间质转化(EMT),并因此丧失上皮标志物的表达。Yu 2013,Eichelberg 2013和Spizzo2011。因此,CLR1501能够鉴定在目前的单标记化验和多标记化验中检测不到的循环肿瘤细胞。
患者101、102、104和108在治疗之前和治疗之后进行抽血(分别为抽取1和抽取2)。患者101对治疗有非常好的部分反应;然而,从抽取1至抽取2中可以看出,该患者的根据定义的CTC计数从0到10增加,表明癌症的进展(表1)。如果仅将CK用作肿瘤细胞的标记物,则患者101的肿瘤细胞计数从470万减少至10(表1,比较抽取1与抽取2)。如果仅将EpCAM用作肿瘤细胞的标记物,则患者101的肿瘤细胞计数从20增加至41(表1,比较抽取1与抽取2)。然而,患者101的总肿瘤细胞计数(CK+和EpCAM+两者的数量)从抽取1至抽取2有所下降,表明单独的标记可以是临床反应更准确的测量,并且患者101的癌细胞描绘了CK和EpCAM的异质表达。此外,患者101的所有CLR 1501+细胞的计数从抽取1到抽取2急剧下降。患者101的EDTA血液采集管中也出现了这种趋势(表2)。因此,单独的CLR 1501可能是比目前的化验更准确的临床反应的测量,否定了鉴定EpCAM和CK两者的需要。
总之,荧光PLE类似物CLR1501成功用于鉴定来自肺癌、甲状腺癌、乳腺癌、宫颈癌、鳞状细胞癌和结肠直肠癌患者的CTC。
