Definitions

  • the present invention relates to the field of biomedicine, and in particular to a drug targeting fibroblast activation protein and an application thereof.
  • Fibroblast activation protein (FAP, also known as fibroblast activation protein ⁇ , FAP ⁇ ) is highly overexpressed on cancer-associated fibroblasts (CAFs) in solid tumors, but is generally not expressed in normal tissues and benign tumors.
  • CAFs cancer-associated fibroblasts
  • Tumor stroma CAFs can promote the growth and infiltration of tumor cells and have become an important target for tumor intervention.
  • Overexpression of the tumor biomarker molecule FAP is a significant feature of CAFs.
  • FAP is a potential target for CAF targeting for tumor diagnosis and treatment.
  • FAP is a type II transmembrane serine protease on tumor fibroblasts. It exists on the cell surface in the form of homodimers and belongs to the proline oligopeptidase family. Its enzymatic activity plays an important role in tumor growth and tissue remodeling.
  • CAF surface-specific FAP can promote tumor progression by promoting matrix reconstruction, participating in signal transduction pathways such as VEGF/AKT/ERK to enhance the ability of tumor cells to invade along fibers, participating in tumor angiogenesis, etc. to form a tumor biological barrier and inhibit the function of effector T cells.
  • the induced high expression of FAP in the tumor stroma also depends on the malignant transformation of tumor tissue. The high expression of FAP is positively correlated with the poor prognosis of tumors.
  • Non-inhibitory FAP monoclonal antibodies themselves have no tumor therapeutic effect, and ADCs with antibodies as carriers are not conducive to clinical development due to their poor permeability, long half-life, long non-target organ uptake and retention time, and greater toxicity.
  • Small molecule FAP selective (targeted) inhibitors that have undergone structural modification and optimized screening have great advantages and development value for the diagnosis and treatment of cancer.
  • the present invention aims to solve one of the technical problems in the related art at least to a certain extent.
  • one object of the present invention is to propose some compounds that have the ability to bind to fibroblast activation protein- ⁇ (FAP), which have good clinical application prospects.
  • FAP fibroblast activation protein- ⁇
  • the compounds of the present invention have better pharmacodynamic activity.
  • the compounds provided by the present invention also have excellent physicochemical properties and pharmacokinetic properties, and have lower toxic and side effects.
  • Fibroblast activation protein-alpha is a type II transmembrane serine protease of the prolyl oligopeptidase family, characterized by its ability to cleave the Pro-AA peptide bond (wherein AA represents any amino acid). It has been shown to play a role in cancer by modifying multiple biologically active signal peptides through the enzymatic activity (Kelly et al., 2005; Edosada et al., 2006).
  • Fibroblast activation protein-alpha expression has been detected on the surface of multiple fibroblasts in the stroma surrounding more than 90% of the multiple epithelial cancers, including but not limited to: malignant breast cancer, colorectal cancer, skin cancer, prostate cancer, pancreatic cancer, etc., and inflammation, including but not limited to: arthritis, fibrosis, etc., while there is almost no expression in multiple healthy tissues. Therefore, treatment and imaging specifically targeting fibroblast activation protein-alpha are of clinical importance.
  • the present invention provides a class of compounds that bind to fibroblast activation protein- ⁇ (FAP), which can be used to prepare drugs for diagnosing and/or treating and/or preventing diseases that express fibroblast activation protein, such as fibrosarcoma, osteosarcoma and other sarcoma malignant tumors, pancreatic cancer, ovarian cancer, melanoma, esophageal cancer, breast cancer, bile duct cancer, lung cancer, liver cancer, colorectal cancer, head and neck cancer, and neuroendocrine tumors.

Abstract

本发明涉及式(X)所示的靶向成纤维细胞活化蛋白的化合物及其应用,进一步涉及包含该类化合物的药物组合物和用途;其中,所述化合物或药物组合物可用于诊断和/或治疗和/或预防一种或多种表达FAP的肿瘤、癌症或细胞。

Description

靶向成纤维细胞活化蛋白的药物及其应用
优先权信息
本申请请求2022年10月14日向中国国家知识产权局提交的、专利申请号为202211260609.3的专利申请的优先权和权益,并且通过参照将其全文并入此处。
技术领域
本发明涉及生物医药领域,具体地,本发明涉及靶向成纤维细胞活化蛋白的药物及其应用。
背景技术
成纤维细胞活化蛋白(FAP,又称为成纤维细胞活化蛋白α,FAPα)在实体肿瘤中与癌相关的成纤维细胞(CAFs)上高度过表达,而在正常组织和良性肿瘤中一般不表达。肿瘤基质CAFs能够促进肿瘤细胞的生长和浸润,已成为肿瘤干预的重要靶标。肿瘤生物标记分子FAP的过表达是CAFs的一个显著特征,FAP在CAF靶向用于肿瘤诊断和治疗方面,是一个具有潜力的靶点。
FAP是一种肿瘤成纤维细胞上的II型跨膜丝氨酸蛋白酶,以同源二聚体形式存在于细胞表面,属于脯氨酸寡肽酶家族,其本身酶活性对于肿瘤生长和组织重构有重要作用。CAF表面特异性FAP可通过促进基质重建、参与VEGF/AKT/ERK等信号转导途径增强肿瘤细胞沿纤维定向侵袭能力、参与肿瘤血管生成等以形成肿瘤生物屏障并抑制效应T细胞的功能,进而促进肿瘤进展。FAP在肿瘤间质中的诱导性高表达也依赖于肿瘤组织的恶性癌变。FAP的高表达程度与肿瘤的预后不良呈正相关性。
而非抑制性FAP单克隆抗体本身无肿瘤治疗作用,且以抗体为载体的ADC因其渗透性差、半衰期长、非靶器官摄取和持留时间长、毒性作用较大等原因,不利于临床开发。经过结构修饰和优化筛选的小分子FAP选择性(靶向性)抑制剂,对于癌症的诊断和治疗具有较大优势和开发价值。

定义和一般术语
现在详细描述本发明的某些实施方案,其实例由随附的结构式和化学式说明。本发明意图涵盖所有的替代、修改和等同技术方案,它们均包括在如权利要求定义的本发明范围内。本领域技术人员应认识到,许多与本文所述类似或等同的方法和材料能够用于实践本发明。本发明绝不限于本文所述的方法和材料。在所结合的文献、专利和类似材料的一篇或多篇与本申请不同或相矛盾的情况下(包括但不限于所定义的术语、术语应用、所描述的技术,等等),以本申请为准。
应进一步认识到,本发明的某些特征,为清楚可见,在多个独立的实施方案中进行了描述,但也可以在单个实施例中以组合形式提供。反之,本发明的各种特征,为简洁起见,在单个实施方案中进行了描述,但也可以单独或以任意适合的子组合提供。
除非另外说明,本发明所使用的所有科技术语具有与本发明所属领域技术人员的通常理解相同的含义。本发明涉及的所有专利和公开出版物通过引用方式整体并入本发明。
本发明将应用以下定义除非其他方面表明。根据本发明的目的,化学元素根据元素周期表,CAS版本和化学物理手册,75th Ed.,1994来定义。另外,有机化学一般原理见“Organic Chemistry”,Thomas Sorrell,University Science Books,Sausalito,1999,和“March's Advanced Organic Chemistry”,Michael B.Smith和Jerry March,John Wiley&Sons,New York,2007,所有上述参考文献均通过引用并入本文中。
除非另有说明或者上下文中有明显的冲突,本文所使用的冠词“一”、“一个(种)”和“所述”旨在包括“至少一个”或“一个或多个”。因此,本文所使用的这些冠词是指 一个或多于一个(即至少一个)宾语的冠词。例如,“一组分”指一个或多个组分,即可能有多于一个的组分被考虑在所述实施方案的实施方式中采用或使用。
术语“包含”为开放式表达,即包括本发明所指明的内容,但并不排除其他方面的内容。
“立体异构体”是指具有相同化学构造,但原子或基团在空间上排列方式不同的化合物。立体异构体包括对映异构体、非对映异构体、构象异构体(旋转异构体)、几何异构体(顺/反)异构体、阻转异构体,等等。
“手性”是具有与其镜像不能重叠性质的分子;而“非手性”是指与其镜像可以重叠的分子。
“对映异构体”是指一个化合物的两个不能重叠但互成镜像关系的异构体。
“非对映异构体”是指有两个或多个手性中心并且其分子不互为镜像的立体异构体。非对映异构体具有不同的物理性质,如熔点、沸点、光谱性质和反应性。非对映异构体混合物可通过高分辨分析操作如电泳和色谱,例如HPLC来分离。
本发明所使用的立体化学定义和规则一般遵循S.P.Parker,Ed.,McGraw-Hill Dictionary of Chemical Terms(1984)McGraw-Hill Book Company,New York;and Eliel,E.and Wilen,S.,“Stereochemistry of Organic Compounds”,John Wiley&Sons,Inc.,New York,1994。
许多有机化合物以光学活性形式存在,即它们具有使平面偏振光的平面发生旋转的能力。在描述光学活性化合物时,使用前缀D和L或R和S来表示分子关于其一个或多个手性中心的绝对构型。前缀d和l或(+)和(-)是用于指定化合物所致平面偏振光旋转的符号,其中(-)或l表示化合物是左旋的。前缀为(+)或d的化合物是右旋的。一种具体的立体异构体是对映异构体,这种异构体的混合物称作对映异构体混合物。对映异构体的50:50混合物称为外消旋混合物或外消旋体,当在化学反应或过程中没有立体选择性或立体特异性时,可出现这种情况。
本发明公开化合物的任何不对称原子(例如,碳等)都可以以外消旋或对映体富集的形式存在,例如(R)-、(S)-或(R,S)-构型形式存在。在某些实施方案中,各不对称原子在(R)-或(S)-构型方面具有至少50%对映体过量,至少60%对映体过量,至少70%对映体过量,至少80%对映体过量,至少90%对映体过量,至少95%对映体过量,或至少99%对映体过量。
依据起始物料和方法的选择,本发明化合物可以以可能的异构体中的一个或它们的混合物,例如外消旋体和非对映异构体混合物(这取决于不对称碳原子的数量)的形式存在。光学活性的(R)-或(S)-异构体可使用手性合成子或手性试剂制备,或使用常规技术拆分。 如果化合物含有一个双键,取代基可能为E或Z构型;如果化合物中含有二取代的环烷基,环烷基的取代基可能有顺式或反式构型。
所得的任何立体异构体的混合物可以依据组分物理化学性质上的差异被分离成纯的或基本纯的几何异构体,对映异构体,非对映异构体,例如,通过色谱法和/或分步结晶法。
可以用已知的方法将任何所得终产物或中间体的外消旋体通过本领域技术人员熟悉的方法拆分成光学对映体,如,通过对获得的其非对映异构的盐进行分离。外消旋的产物也可以通过手性色谱来分离,如,使用手性吸附剂的高效液相色谱(HPLC)。特别地,对映异构体可以通过不对称合成制备,例如,可参考Jacques,et al.,Enantiomers,Racemates and Resolutions(Wiley Interscience,New York,1981);Principles of Asymmetric Synthesis(2nd Ed.Robert E.Gawley,Jeffrey Aubé,Elsevier,Oxford,UK,2012);Eliel,E.L.Stereochemistry of Carbon Compounds(McGraw-Hill,NY,1962);Wilen,S.H.Tables of Resolving Agents and Optical Resolutions p.268(E.L.Eliel,Ed.,Univ.of Notre Dame Press,Notre Dame,IN 1972);Chiral Separation Techniques:A Practical Approach(Subramanian,G.Ed.,Wiley-VCH Verlag GmbH&Co.KGaA,Weinheim,Germany,2007)。
术语“互变异构体”或“互变异构形式”是指具有不同能量的可通过低能垒(low energy barrier)互相转化的结构异构体。若互变异构是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(protontautomer)(也称为质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。
像本发明所描述的,本发明的化合物可以任选地被一个或多个取代基所取代,如上面的通式化合物,或者像实施例里面特殊的例子,子类,和本发明所包含的一类化合物。
除非另有说明或者上下文中有明显的冲突,本文所使用的冠词“一”、“一个(种)”和“所述”旨在包括“至少一个”或“一个或多个”。因此,本文所使用的这些冠词是指一个或多于一个(即至少一个)宾语的冠词。例如,“一组分”指一个或多个组分,即可能有多于一个的组分被考虑在所述实施方案的实施方式中采用或使用。
术语“取代的”一般表示所给结构中的一个或多个氢原子被具体取代基所取代。除非其他方面表明,一个被取代的基团可以有一个取代基在基团各个可取代的位置进行取代。当所给出的结构式中不止一个位置能被选自具体基团的一个或多个取代基所取代时,那么取代基可以相同或不同地在各个可取代的位置取代。
术语“未取代的”,表示指定基团不带有取代基。
如本发明所描述的,本发明的化合物可以任选地被一个或多个取代基所取代,如上面 的通式化合物,或者如实施例里面特殊的例子,子类,和本发明所包含的一类化合物。应了解“任选取代的”这个术语与“取代或未取代的”这个术语可以交换使用。一般而言,术语“任选地”不论是否位于术语“取代的”之前,表示所给结构中的一个或多个氢原子被具体取代基所取代。除非其他方面表明,一个任选的取代基团可以有一个取代基在基团各个可取代的位置进行取代。当所给出的结构式中不只一个位置能被选自具体基团的一个或多个取代基所取代,那么取代基可以相同或不同地在各个位置取代。其中所述的取代基可以是,但并不限于,氘、羟基、氨基、卤素、氰基、芳基、杂芳基、烷氧基、烷氨基、烷硫基、烷基、烯基、炔基、杂环基、巯基、硝基、芳氧基、杂芳氧基、氧代(=O)、羧基、羟基取代的烷氧基、羟基取代的烷基-C(=O)-、烷基-C(=O)-、烷基-S(=O)-、烷基-S(=O)2-、羟基取代的烷基-S(=O)-、羟基取代的烷基-S(=O)2-、羧基取代的烷氧基等等。
另外,需要说明的是,除非以其他方式明确指出,在本发明中所采用的描述方式“各…独立地为”与“…各自独立地为”和“…独立地为”可以互换,均应做广义理解,其既可以是指在不同基团中,相同符号之间所表达的具体选项之间互相不影响,也可以表示在相同的基团中,相同符号之间所表达的具体选项之间互相不影响。以R为例,-RC(O)-、-NRC(S)NR’-、-NRC(O)O-、-C(O)NR-或-NR-C(O)-之间R的具体选项互相之间不受影响;同时,在同一化学式如果出现2个或2个以上的R,R的具体选项互相之间也不受影响。
当通过从左向右书写的常规化学式描述取代基时,该取代基也同样包括从右向左书写结构式时所得到的在化学上等同的取代基。举例而言,CH2O等同于OCH2。如本文所用,表示基团的连接位点。

实施例4 NYM030药物在HT1080肿瘤模型疗效实验
实验动物HT1080模型由苏州恒佳生物技术有限公司提供,是基于BALB/c裸鼠建立的HT1080皮下异位移植瘤模型,该模型为人纤维肉瘤细胞构建的小鼠模型。随机选择20只雌性HT1080异位人纤维肉瘤模型鼠进行实验。实验前先测量肿瘤大小,并根据肿瘤大小按顺序排列,选出瘤体积在合适大小的16只肿瘤鼠入组,分为三组:编号分别为G1、G2、G3。其中G1组(治疗组)六只肿瘤鼠,每只动物经尾静脉注射NYM030的生理盐水溶液,给药量约为10mg/kg,按照每只荷瘤鼠体重计算注射药物量。G2组(阳性对照组)六只肿瘤鼠,每只动物经尾静脉注射伊立替康的生理盐水溶液,给药量约为5mg/kg(NYM030和伊立替康的给药摩尔量相同,即细胞毒性药物给药量相同)。G3组(对照组)四只肿瘤鼠,每只动物经尾静脉注射生理盐水溶液,给药量与G1、G2组体积接近,并记录各组注射时间。G1组、G2组、G3组于给药前、给药后2、4、6、8、10、12、14天测量肿瘤体积大小(长径和短径)和称量体重,同时观察小鼠状态,并做好准确记录。肿瘤 疗效评价期间测量的肿瘤长径和短径用于计算肿瘤体积大小,计算公式如下:肿瘤体积(tumor volume,TV)=a×b2/2(a为长径、b为短径)。各组肿瘤体积大小趋势图见图8,小鼠体重变化趋势图见图9,可以看到NYM030相对于伊立替康和生理盐水,其抑制肿瘤生长的速度更加明显,且小鼠体重并无明显变化,说明NYM030有很好地抗肿瘤效果且具有较好的安全性。

实验分为阴性对照和NYM030的3个剂量(10mg/kg,3mg/kg和1mg/kg,使用5%葡萄糖溶液配置成给药溶液)的各自单药组,每组8只,尾静脉注射给药,给药体积为10μL/g,共给药两周,实验于第28天结束。具体给药信息详见表4。在给药开始前,称量所有动物的体重,并用游标卡尺测量肿瘤体积。给药前、给药后测量肿瘤体积大小(长径和短径)和称量体重,同时观察肿瘤生长及治疗对动物正常行为的影响,包括实验动物的活动性,摄食和饮水情况,体重增加或降低情况及其它异常情况。根据肿瘤体积的抑制率(TGI)进行疗效评价,根据动物体重变化(如附图11)和死亡情况进行安全性评价。计算肿瘤抑制率,TGI(%),计算公式如下:TGI%=(1-T/C)×100%,T和C分别为治疗组和对照组在某一特定时间点的平均肿瘤体积;肿瘤体积(tumor volume,TV)=a×b2/2(a为长径、b为短径)。
如附图10所示,在第24天,阴性对照组有小鼠肿瘤体积超过3000mm3,被安乐死。在第24天,阴性对照组平均肿瘤体积为2997.74mm3;NYM030(10mg/kg,3mg/kg和1mg/kg)各剂量组均能显著性抑制肿瘤生长,TGI分别为60.69%,46.59%和44.46%,其中,高剂量组的肿瘤抑制效果更好,阴性对照组和NYM030各个剂量组无明显体重下降,小鼠均无异常情况出现,说明NYM030安全性良好。
表4给药信息
实施例6连续给药毒性实验
小鼠模型为6-8周龄雌性ICR小鼠购自苏州恒佳生物技术有限公司。随机选取6只ICR小鼠给予NYM030药物,单次给药10mg/kg,连续给药7天,观察动物一般指标(动物毛发、活动度、饮食等)、动物死亡情况(死亡时间等)及称量动物体重变化(给药前、观察期间、试验结束处死前),并于实验最后一天处死,解剖观察其心、肝、脾、肺、肾等主要脏器的组织变化。图12中体重变化用于评价某一时间点体重与实验开始前体重的变化情况,计算公式为:体重变化=称量时体重/初始体重*100%。
如图12所示,连续给药7天后,所有小鼠无死亡,无异常反应,解剖观察脏器无异常,且实验过程中体重并无明显变化。可见,NYM030分子安全性良好。
