背景技术
现代分子生物学从3个基本层次上调控蛋白的表达水平:首先,在DNA水平,通过基因敲除,从而使目标蛋白的DNA失活;其次,在mRNA水平,通过小分子RNA,与目标蛋白的mRNA结合,从而抑制mRNA的翻译及表达;再次,在蛋白水平,通过对翻译后靶蛋白的修饰,例如甲基化、磷酸化、糖基化等,从而调整靶蛋白的量及活性。
就药物研发的总体发展来看,小分子和大分子两种药物形式都有各自的优势与不足。如小分子药物的发展一直面临如何维持体内药物浓度以及耐药性等关键挑战。有些靶点部位的形状不利于小分子的药物设计而成为“不可成药”的靶点。针对这些靶点目前还未找到有效的调控方式。单抗虽相对于小分子具有高亲和力和高选择性的优势,易于开发成高效、高选择性的药物,但其最大的弊端在于无法透过细胞膜,因此无法作用于胞内靶点。抗体药物偶联体(ADC)利用具有内吞性的抗体提供靶向并作为载体将超级毒素药物送达靶向部位。ADC类药物开发遇到的瓶颈是治疗窗口不够宽,除了抗体本身引起的毒副作用外,超级毒素会因偶联的非均一性而在到达靶位前脱落,引起严重毒副作用。此外,泛素-蛋白酶体系统正常生理功能负责清理细胞中变性、变异或者有害的蛋白。
综上所述,本领域迫切需要开发能够更高效、且可重复利用的降解靶蛋白从而治疗相关疾病的化合物。

靶向蛋白酶降解(Targeted Enzyme Degradation,TED)平台
本发明提供基于本发明偶联物的靶向蛋白酶降解(TED)平台,该平台利用了细胞内的“清洁工”—泛素-蛋白酶体系统。
典型地,基于本发明TED技术,可利用细胞自身的蛋白质破坏机制来从细胞中去除特定致癌病蛋白,因此是一种靶向治疗的替代方法。
与传统蛋白抑制剂作用原理不同,本发明的TED技术是一个双功能杂合化合物,一边用来结合目标蛋白,另一边用来结合一个E3连接酶,使得目标蛋白可以与E3连接酶结合,把目标蛋白泛素化,从而被蛋白组降解。理论上TED技术只是提供结合活性,不需直接抑制目标蛋白的功能活性,又可以重复利用,因此,具有优异的应用前景。
特别地,本发明的经过优化的TED分子,具备优越的靶蛋白降解能力,从而抑制病灶细胞生长。此外,本发明的TED(即R TED)通过具有特定结构的连接头(例如,链上存在细胞表面或细胞质内可裂解的二价连接部分(如-S-S-,或-AN-、-AAN-、-VA-、-GGFG-、-AAFG、-VCit-、-VL-等肽链)和亲水性二价连接部分(如PEG链、含酸性官能团的侧链如-SO 3H、-PO 3H 2、-COOH等))跟具有靶向肿瘤组织的配体(如叶酸等)偶联形成本文所述的ACTED分子(或偶联物)。
具有上述结构的ACTED进入血液循环,其通过特定结构的连接头所偶联的配体部分跟肿瘤细胞表面的抗原或受体结合,从而能够快速富集到肿瘤组织。在与肿瘤细胞结合后,本发明的ACTED可发生以下作用:例如,1.经过受体介导的内吞作用进入细胞,在细胞质中,被酸性环境,或者GSH(谷胱甘肽),或者特异性酶切割,释放出活性分子TED,TED再与细胞内的靶蛋白和E3酶结合,通过泛素介导的蛋白酶体,降解靶蛋白,进而杀死肿瘤细胞;2.ACTED在细胞表面即被微环境的酸性环境,或者GSH,或特异性酶切割,释放出TED,TED再扩散进入细胞内发挥降解靶蛋白并杀伤肿瘤细胞的作用。可见,本发明还提供了一种基于靶向肿瘤微环境及低氧状态的前药(Pro-drug)偶联物”。
因此,本发明的ACTED的优点可以分为两个方面:1.将更多的TED富集到肿瘤组织,并帮助TED进入肿瘤细胞,降解靶蛋白从而杀伤肿瘤细胞,提高了TED的利用率;和2.ACTED极少结合正常细胞,故循环过程中更少的TED进入正常组织,减少了毒副作用。
一些示例性的跟具有靶向肿瘤组织的配体的连接头如下,其中仅示例性地列举了代表性的连接片段,应当理解,其中各片段之间还可能存在诸如-NHCO-、-NH-、-CO-、亚甲基、常见氨基酸的残基等常见的连接基团

多肽元件
如本文所用,术语“多肽元件”包括肽段(如3-20aa的短肽)或蛋白。此外,该术语还包括完整的蛋白或其片段。优选的多肽元件包括抗体(如完整抗体、单链抗体、纳米抗体、抗体片段),尤其是针对肿瘤细胞标志物(如位于肿瘤细胞表面的肿瘤标志物,如细胞表面的受体)或针对炎性因子(如与自身免疫疾病相关的炎性因子)的抗体。
如本文所用,术语“抗体”或“免疫球蛋白”是有相同结构特征的约150000道尔顿的异四聚糖蛋白, 其由两个相同的轻链(L)和两个相同的重链(H)组成。每条轻链通过一个共价二硫键与重链相连,而不同免疫球蛋白同种型的重链间的二硫键数目不同。每条重链和轻链也有规则间隔的链内二硫键。每条重链的一端有可变区(VH),其后是多个恒定区。每条轻链的一端有可变区(VL),另一端有恒定区;轻链的恒定区与重链的第一个恒定区相对,轻链的可变区与重链的可变区相对。特殊的氨基酸残基在轻链和重链的可变区之间形成界面。
如本文所用,术语“单域抗体”、“纳米抗体”具有相同的含义,指克隆抗体重链的可变区,构建仅由一个重链可变区组成的单域抗体,它是具有完整功能的最小的抗原结合片段。通常先获得天然缺失轻链和重链恒定区1(CH1)的抗体后,再克隆抗体重链的可变区,构建仅由一个重链可变区组成的单域抗体。
如本文所用,术语“可变”表示抗体中可变区的某些部分在序列上有所不同,它形成了各种特定抗体对其特定抗原的结合和特异性。然而,可变性并不均匀地分布在整个抗体可变区中。它集中于轻链和重链可变区中称为互补决定区(CDR)或超变区中的三个片段中。可变区中较保守的部分称为构架区(FR)。天然重链和轻链的可变区中各自包含四个FR区,它们大致上呈β-折叠构型,由形成连接环的三个CDR相连,在某些情况下可形成部分折叠结构。每条链中的CDR通过FR区紧密地靠在一起并与另一链的CDR一起形成了抗体的抗原结合部位(参见Kabat等,NIH Publ.No.91-3242,卷I,647-669页(1991))。恒定区不直接参与抗体与抗原的结合,但是它们表现出不同的效应功能,例如参与抗体的依赖于抗体的细胞毒性。
脊椎动物抗体(免疫球蛋白)的“轻链”可根据其恒定区的氨基酸序列归为明显不同的两类(称为κ和λ)中的一类。根据其重链恒定区的氨基酸序列,免疫球蛋白可以分为不同的种类。主要有5类免疫球蛋白:IgA,IgD,IgE,IgG和IgM,其中一些还可进一步分成亚类(同种型),如IgG1,IgG2,IgG3,IgG4,IgA和IgA2。对应于不同类免疫球蛋白的重链恒定区分别称为α、δ、ε、γ、和μ。不同类免疫球蛋白的亚单位结构和三维构型是本领域人员所熟知的。
一般,抗体的抗原结合特性可由位于重链和轻链可变区的3个特定的区域来描述,称为可变区域(CDR),将该段间隔成4个框架区域(FR),4个FR的氨基酸序列相对比较保守,不直接参与结合反应。这些CDR形成环状结构,通过其间的FR形成的β折叠在空间结构上相互靠近,重链上的CDR和相应轻链上的CDR构成了抗体的抗原结合位点。可以通过比较同类型的抗体的氨基酸序列来确定是哪些氨基酸构成了FR或CDR区域。
本发明中,多肽元件不仅可包括完整的抗体,还包括具有免疫活性的抗体的片段(如如Fab或(Fab’) 2片段;抗体重链;或抗体轻链)或抗体与其他序列形成的融合蛋白。因此,本发明还包括所述抗体的片段、衍生物和类似物。

实验动物:雌性BALB/c裸鼠(只数:65只;周龄:6-8周)从维通利华购买,饲养于苏州圣苏新药开发有限公司SPF动物房,温度20~25℃,相对湿度40%~70%,明暗照明各12小时;动物自由饮水及采食。正常喂养约5天后,经兽医检验,体征状况良好小鼠可入选本实验。分组前使用记号笔于动物尾根部进行标识,分组后每只动物均用耳部剪缺方式标识。
动物模型制备:收取对数生长期NCI-H82细胞,细胞计数后重悬于含50%的无血清RPMI-1640培养液和50%的Matrigel中,调整细胞浓度至1.5×10 7细胞/mL;用移液器吹打细胞使其分散均匀后装入50-mL离心管中,将离心管置于冰盒中;用1-mL注射器吸取细胞悬液,注射到裸鼠前右肢腋窝皮下,每只动物接种200μL(3.0×10 6细胞/只),建立NCI-H82裸鼠移植瘤模型。接种后定期观察动物状态及肿瘤生长情况,使用电子游标卡尺测量瘤径,数据输入Excel电子表格计算肿瘤体积。待肿瘤体积达到100~300mm 3,挑选健康状况良好、肿瘤体积相近的动物,采用随机区组法分10组(n=4)。以分组当天为实验第一天(D1),实验开始后每周测量2次瘤径,计算肿瘤体积,同时称量动物体重并记录。
肿瘤体积(TV)计算公式如下:
TV(mm 3)=l×w 2/2
其中,l表示肿瘤长径(mm);w表示肿瘤短径(mm)。
给药制剂配制
空白溶剂配制:分别吸取适量体积的DMSO、30%Solutol水溶液和超纯水,混合均匀,作为空白溶媒,室温保存备用。混合溶媒中DMSO、30%Solutol水溶液和超纯水的比例为5%、20%和75%。

数据记录、计算公式
相对肿瘤体积(RTV)的计算公式为:
RTV=TV t/TV initial
其中,TV initial为分组给药时测量到的肿瘤体积;TV t为给药期间每一次测量时的肿瘤体积。
相对肿瘤增殖率(%T/C)的计算公式为:
%T/C=100%×(RTV T/RTV C)
其中,RTV T表示治疗组RTV;RTV C表示溶剂对照组RTV。
肿瘤生长抑制率TGI(%)的计算公式为:
TGI(%)=100%×[1–(TV t(T)–TV initial(T))/(TV t(C)–TV initial(C))]
其中,TV t(T)表示治疗组每次测量的肿瘤体积;TV initial(T)表示分组给药时治疗组的肿瘤体积; TV t(C)表示溶剂对照组每次测量的肿瘤体积;TV initial(C)表示分组给药时溶剂对照组的肿瘤体积。
动物相对体重(RBW)的计算公式为:
RBW=100×BW t/BW initial
其中,BW initial为分组给药时动物体重;BW t为给药期间每一次称量的动物体重。
动物体重下降率的计算公式为:
动物体重下降率=100%×(BW initial-BW t)/BW initial
其中,BW t表示给药期间每次测量的动物体重;BW initial表示分组给药时的动物体重。
瘤重抑瘤率IR(%)的计算公式为:
IR(%)=100%×(W C-W T)/W C
其中,W C表示对照组瘤重;W T表示治疗组瘤重。
统计分析方法:试验数据用Microsoft Office Excel 2007软件进行计算和相关统计学处理。数据除特别说明外,用均数±标准误(Mean±SE)表示,两组间比较采用t-检验。
结果如图3所示,可见跟空白组比较,UB-181322显示出抑制肿瘤生长的效果(A),且给药期间小鼠体重变化不大,毒性低(B)。
