Definitions

  • the present invention relates to a compound represented by formula (IA), its optical isomers and pharmacologically acceptable salts, and the application of the compound as a STING agonist.
  • STING is activated in three ways: 1) By combining exogenous (3', 3') cyclic dinucleotides (c-diGMP, c-diAMP and c-GAMP) released by invading bacteria or archaea ) Activation, which shows that STING has the role of innate immune activation in anti-infection; 2) activation by binding (2'3') cyclic guanosine monophosphate adenosine monophosphate (2', 3'c-GAMP) It is produced by the cyclic GMP-AMP dinucleotide synthase (cGAS) in the presence of exogenous double-stranded DNA (for example, released by invading bacteria, viruses or protozoa) or self-DNA in mammals.
  • Source cyclic dinucleotide which shows that STING can be induced by endogenous or exogenous DNA to activate innate immunity; 3) It is activated by binding synthetic ligands.
  • STING acts as a sensor of DNA in the cytoplasm, and its activation can lead to the activation of the downstream IRF3 and NF- ⁇ B pathways to activate the immune system.
  • the activation of the NF- ⁇ B pathway leads to the activation of a series of inflammatory cytokines downstream, and the activation of the IRF3 pathway leads to the activation of type I interferons (IFN- ⁇ / ⁇ ), dendritic cells, cytotoxic cells, NK cells, etc.
  • IFN- ⁇ / ⁇ type I interferons
  • DNA in the human body usually does not activate the STING protein, because under normal circumstances DNA can only exist in the nucleus (except for mitochondrial DNA). But if DNA leaks into the cytoplasm, it will activate STING and trigger an immune response. Recently, it has been found that radiotherapy and chemotherapy can also activate STING, which may also be caused by DNA leakage in dead tumor cells.

There is a certain amount of fluorescein-labeled c-di-GMP and different concentrations of the test compound in the reaction system. When the C-terminal protein of recombinant human STING is added, the two small molecules competitively bind to the protein. The bound fluorescein-labeled c-di-GMP rotates slowly in the liquid phase, and the detected fluorescence polarization degree is also higher at this time. The degree of fluorescence polarization is inversely related to the concentration and affinity of the test compound. We can accurately know the affinity of the test compound to human STING by detecting the size of the polarized light in the reaction system.

技术领域
本发明涉及式(ⅠA)所示化合物、其光学异构体及其药效上可接受的盐，以及该化合物作为STING激动剂的应用。
背景技术
长久以来，科研人员一直试图通过激活病人的免疫系统，使他们自身的免疫系统能够有效地对抗肿瘤，完全清除肿瘤细胞。但肿瘤自发缓解的概率极低，因此绝大多数病人也无法因此获益。上世纪六七十年代，出现了通过卡介苗注射，非特异性的强化免疫系统功能等治疗方法。八十年代，能够活化T细胞以及NK细胞的干扰素和IL-2也被尝试应用于癌症的治疗，但这些方法依然有非常多的局限性，诸如外源细胞因子在血液中的半寿期非常短，这必须采用频繁给药和高剂量予以补偿。非特异性活化免疫系统导致正常组织的炎症反应，细胞因子风暴等，因此很多疗法的毒副作用非常强。作为在体中触发具有特异性治疗有益性细胞因子产生的免疫调节剂，以STING为靶标的疗法为解决这一困境带来了曙光。
目前己知人STING以三种方式激活：1)通过结合正在侵入的细菌或古细菌释放的外源(3’，3’)环状二核苷酸(c-diGMP、c-diAMP和c-GAMP)激活，这显示了STING具有在抗感染中先天免疫活化的作用；2)通过结合(2’3’)环状鸟苷单磷酸腺苷单磷酸酯(2’,3’c-GAMP)激活，它是由环状GMP-AMP二核苷酸合成酶(cGAS)在外源双链DNA(例如由正在侵入的细菌、病毒或原虫释放的)或哺乳动物中的自我DNA存在时诱导产生的内源环状二核苷酸，这显示了STING具有受内源或外源DNA诱导活化先天免疫的作用；3)通过结合合成性配体活化。
STING作为细胞质中DNA的感受器，它的活化可导致下游IRF3和NF-κB两条通路的激活以激活免疫系统。NF-κB通路激活导致下游一系列致炎症细胞因子的活化，而IRF3通路的激活，导致了一型干扰素(IFN-α/β)的激活,树突状细胞，细胞毒性细胞，NK细胞等的活化，从而发挥出抗肿瘤作用。
人体内的DNA通常不会激活STING蛋白，因为正常情况下DNA仅能够存在于细胞核之内(线粒体DNA除外)。但如果DNA泄漏到胞浆之中，则会活化STING，引发免疫反应。最近发现放疗以及化疗同样能够激活STING，这可能也是由于死亡的肿瘤细胞内的DNA泄漏导致STING被激活。

定义和说明
除非另有说明，本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的，而应该按照普通的含义去理解。当本文中出现商品名时，意在指代其对应的商品或其活性成分。
这里所采用的术语“药学上可接受的”，是针对那些化合物、材料、组合物和/或剂型而言，它们在可靠的医学判断的范围之内，适用于与人类和动物的组织接触使用，而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症，与合理的利益/风险比相称。
术语“药学上可接受的盐”是指本发明化合物的盐，由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时，可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物的中性形式接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机胺或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时，可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物的中性形式接触的方式获得酸加成盐。药学上可接受的酸加成盐的实例包括无机酸盐，所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸，碳酸氢根，磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等；以及有机酸盐，所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸；还包括氨基酸(如精氨酸等)的盐，以及如葡糖醛酸等有机酸的盐。本发明的某些特定的化合物含有碱性和酸性的官能团，从而可以被转换成任一碱或酸加成盐。

本发明的化合物可以存在特定的。除非另有说明，术语“互变异构体”或“互变异构体形式”是指在室 温下，不同官能团异构体处于动态平衡，并能很快的相互转化。若互变异构体是可能的(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(proton tautomer)(也称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。价键异构体(valence tautomer)包括一些成键电子的重组来进行的相互转化。其中酮-烯醇互变异构化的具体实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮两个互变异构体之间的互变。
除非另有说明，术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100％，并且，该异构体或对映体的含量大于等于60％，或者大于等于70％，或者大于等于80％，或者大于等于90％，或者大于等于95％，或者大于等于96％，或者大于等于97％，或者大于等于98％，或者大于等于99％，或者大于等于99.5％，或者大于等于99.6％，或者大于等于99.7％，或者大于等于99.8％，或者大于等于99.9％。
除非另有说明，术语“异构体过量”或“对映体过量”指两种异构体或两种对映体相对百分数之间的差值。例如，其中一种异构体或对映体的含量为90％，另一种异构体或对映体的含量为10％，则异构体或对映体过量(ee值)为80％。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体，可以通过不对称合成或者具有手性助剂的衍生作用来制备，其中将所得非对映体混合物分离，并且辅助基团裂开以提供纯的所需对映异构体。或者，当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时，与适当的光学活性的酸或碱形成非对映异构体的盐，然后通过本领域所公知的常规方法进行非对映异构体拆分，然后回收得到纯的对映体。此外，对映异构体和非对映异构体的分离通常是通过使用色谱法完成的，所述色谱法采用手性固定相，并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如，可用放射性同位素标记化合物，比如氚( 3H)，碘-125( 125I)或C-14( 14C)。又例如，可用重氢取代氢形成氘代药物，氘与碳构成的键比普通氢与碳构成的键更坚固，相比于未氘化药物，氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换，无论放射性与否，都包括在本发明的范围之内。“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的，并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代，可以包括重氢和氢的变体，只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即＝O)时，意味着两个氢原子被取代。氧取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代，也可以不被取代，除非另有规定，取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时，其在每一种情况下的定义都是独立的。因此，例如，如果一个基团被0-2个R所取代，则所述基团可以任选地至多被两个R所取代，并且每种情况下的R都有独立的选项。此外，取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时，比如-(CRR)0-，表示该连接基团为单键。
当其中一个变量选自单键时，表示其连接的两个基团直接相连，比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当所列举的连接基团没有指明其连接方向，其连接方向是任意的，例如，
Figure PCTCN2020104506-appb-000061
中连接基团L为-M-W-，此时-M-W-既可以按与从左往右的读取顺序相同的方向连接苯环和环戊烷构成

也可以按照与从左往右的读取顺序相反的方向连接苯环和环戊烷构成

所述连接基团、取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
除非另有规定，环上原子的数目通常被定义为环的元数，例如，“5-6元环”是指环绕排列5-6个原子的“环”。
除非另有规定，“5～6元杂环”其表示由5至6个环原子组成的饱和或者不饱和环状基团，其1、2、3或4个环原子为独立选自O、S和N的杂原子，其余为碳原子，其中氮原子任选地被季铵化，氮和硫杂原子可任选被氧化(即NO和S(O)p，p是1或2)。其包括单环和双环体系，其中双环体系包括螺环、并环和桥环。此外，就该“5-6元杂环”而言，杂原子可以占据杂环烷基与分子其余部分的连接位置。所述5-6元杂环包括5元和6元杂环。5-6元杂环的实例包括但不限于

实验例1：STING体外结合测试实验
荧光偏振测试法(fluorescence polarization assay,FP assay)被用于检测化合物对人STING蛋白的亲和力。反应体系中有一定量的荧光素标记的c-di-GMP和不同浓度的待测化合物，当加入重组人STING的C端蛋白，两种小分子与蛋白竞争性结合。结合态的荧光素标记的c-di-GMP在液相中转动较慢，此时检测到的荧光偏振程度也较高。荧光偏振程度与待测化合物浓度，亲和力呈反比关系。我们通过检测反应系中偏振光的大小，就可以精确地得知待测化合物对人STING的亲和力。
实验中用到的可溶性人STING蛋白序列是截取自人野生型内质网结合蛋白STING的C端部分，从140氨基酸至379氨基酸。人STING蛋白有多种序列差异的等位基因，不同等位基因对CDN亲和力不同(Yi,et.al.,“Single Nucleotide Polymorphisms of Human STING can affect innate immune response to cyclic dinucleotides"PLOS ONE.2013,8(10),e77846)。野生型STING序列(G230，R232，R293)约占了总体的57.9％。重组STING蛋白的N端是6His-SUMO序列，以利于蛋白正确折叠及纯化，经蛋白酶切除，C端STING用于FP测试。
FP测试使用384孔板，在每孔10μl反应体系中加有终浓度30nM的荧光素标记的c-di-GMP，10μM的人STING蛋白，和不同浓度的参照化合物或待测化合物。1000g离心1分钟，室温避光孵育30分钟， 用Envision读板。

实验例2：THP-dual体外结合测试实验
测试所用THP1-Dual TM细胞(InvivoGen目录代码：thpd-nfis)，是通过在人单核细胞系THP1中稳定整合两个诱导型报告基因构建。分泌型胚胎碱性磷酸酶(SEAP)报告基因的启动子序列组成包括一个IFN-β的基本启动子和上游的5个拷贝的NF-κB共表达转录应答元件(NF-κB consensus transcriptional response element)和3个拷贝的c-Rel结合位点。分泌性萤光素酶(Lucia)报告基因由5个干扰素刺激反应元件(interferon(IFN)-stimulated response elements)和一个ISG54的基本启动子驱动。从而使得同时研究STING的两个主要下游信号传导途径成为可能：通过检测SEAP活性研究NF KB途径：和通过评估Lucia荧光素酶的活性研究IRF途径。
向96孔板的每个孔添加20μL参照或待测化合物，随后添加180μl含THP1-Dual TM细胞的无FBS的RPMI-1640培养液液(大约90,000个细胞/孔)。将平板在37℃在5％CO 2下孵育30分钟后，1000rpm离心10分钟，弃上清，用200μl/孔RPMI-1640洗两次，添加200μl/孔RPMI-1640培养18小时。使用根据制造商的说明制备及使用的QUANTI-Luc TM定量IFN-α/β的活性。

结论：与对照组相比，给药组小鼠肿瘤增长速度明显变慢。化合物1对小鼠肿瘤生长的抑制作用呈现出剂量依赖性。
