Definitions
- the present invention relates to the field of medicine, and relates to a compound represented by the general formula (I), a preparation method thereof, a pharmaceutical composition containing the derivative, and a therapeutic agent, especially its use as an STING modulator and treatment of STING-mediated Use of diseases or conditions, such as inflammation, allergic and autoimmune diseases, infectious diseases, cancer, precancerous syndromes.
- diseases or conditions such as inflammation, allergic and autoimmune diseases, infectious diseases, cancer, precancerous syndromes.
- the human immune system can generally be divided into two types of systems, called “innate immunity” and “adaptive immunity”.
- the innate immune system of the immune system is mainly responsible for the passage of many soluble factors (including the complement system and chemokine/cytokine system); these factors act on many different cell types, including mast cells, macrophages, dendritic cells and natural Kill cells to resist various pathogens such as viruses, bacteria, fungi and parasites.
- the adaptive immune system involves delayed and longer-lasting antibody responses and CD8 + and CD4 + T cell responses that play a key role in immune memory to antigens.
- the innate immune system has no antigen specificity, but it does respond to multiple effect mechanisms.
- the mechanism by which the innate immune system mediates its response includes phagocytosis, activation of the complement system, and the production of soluble biologically active molecules such as cytokines or chemokines.
- DAMP damage-related molecular patterns
- PAMP pathogen-related molecular patterns
- the innate immune system can provide extensive protection to the body to resist a wide range of threats to the host.
- the innate immune system can detect free cytoplasmic DNA and RNA in PAMP and DAMP. It has recently been demonstrated that the main sensor for cytosolic DNA is cGAS (cyclic GMP-AMP synthase).
- CDN cyclic dinucleotide 2'-3'cGAMP
- type I interferon has antiviral activity and can inhibit the replication of human hepatitis B virus and hepatitis C virus.
- type I interferons and compounds that can induce the production of type I interferons can be used to treat human cancers. Such molecules may be used as anticancer agents with multiple active pathways. Interferon can directly inhibit the proliferation of human tumor cells and can act synergistically with various approved chemotherapeutics. Type I interferon can significantly enhance the anti-tumor immune response by inducing the activation of adaptive and innate immune cells. Finally, by regulating the expression of enzymes related to tissue remodeling, interferon can inhibit tumor invasiveness.
- STING is considered to be the key adaptor protein in the cGAS-STING-IFN cascade, and the role of STING in the activation of the innate immune system against tumors has also been recognized.

- tumor-derived DNA is present in the cytoplasm of certain antigen-presenting cells (such as tumor-infiltrating dendritic cells), which may be produced by tumor cell stress or cell death.
- This tumor-derived DNA is known to activate cGAS, which leads to the production of cyclic nucleotides that have been shown to activate STING, leading to the production of related type 1 interferons such as interferon beta (Woo, SR et al., Immunity (2014) 41: 830 -842).
- the downstream signal transduction pathways stimulated and produced by STING may also contribute to the recruitment of effector T cells into the inflamed tumor microenvironment (Woo, S.R. Trends in Immunol (2015) 36: 250-256).
- STING activation in the tumor microenvironment can induce an adaptive immune response, leading to anti-tumor activity. Therefore, in those STING-deficient tumors, by activating antigen-presenting cells and dendritic cells (APC and DC) and inducing adaptive immune responses, these tumors still have anti-tumor activity. With more and more data showing that the cGAS-STING cytosolic DNA sensory pathway has a significant ability to induce type I interferons, the development of STING activators has rapidly occupied an important position in the field of anti-tumor therapy today.
- CDN cyclic dinucleotides Due to easy hydrolysis in the body and very low permeability, natural cyclic dinucleotides (CDN) are not suitable for clinical development.
- Aduro Company modified the natural cyclic dinucleotide structure and replaced the phosphoric acid ester with phosphorothioate to obtain the compound ADU-S100 with higher druggability.

Abstract
可增强免疫活性的杂环化合物、其制备方法及其在医药上的应用。具体为一种通式(I)所示的化合物、其制备方法及含有该衍生物的药物组合物以及其作为治疗剂,特别是作为STING调节剂的用途以及治疗STING介导的疾病或病症的用途,例如炎症、过敏性和自身免疫性疾病、感染性疾病、癌症、癌前综合征。
Description
本发明涉及属于医药领域,涉及一种通式(I)所示的化合物、其制备方法及含有该衍生物的药物组合物以及治疗剂,特别是作为STING调节剂的用途以及治疗STING介导的疾病或病症的用途,例如炎症、过敏性和自身免疫性疾病、感染性疾病、癌症、癌前综合征。
人免疫系统通常可分为两类系统,称为“先天性免疫”和“适应性免疫”。免疫系统的先天性免疫系统主要负责通过许多可溶性因子(包括补体系统和趋化因子/细胞因子系统);这些因子作用于许多不同的细胞类型,包括肥大细胞,巨噬细胞,树突细胞和自然杀伤细胞以抵御各种病原体,如病毒,细菌,真菌和寄生虫。适应性免疫系统涉及在对抗原的免疫记忆中发挥关键作用的延迟的和更持久的抗体应答以及CD8
+和CD4
+T细胞应答。
先天免疫系统没有抗原特异性,但确实对多种效应机制有反应。先天免疫系统介导其反应的机制包括吞噬作用,补体系统的活化以及可溶性生物活性分子如细胞因子或趋化因子的产生。通过对上述这些与损伤相关的分子模式(DAMP)或病原体相关分子模式(PAMP)的响应,先天免疫系统能够对机体提供广泛的保护,以抵抗对宿主的广泛威胁。先天免疫系统可以检测到PAMP和DAMP中游离的胞质DNA和RNA。最近证明细胞溶质DNA的主要传感器是cGAS(环状GMP-AMP合酶)。在识别细胞溶质DNA后,cGAS催化环二核苷酸2'-3'cGAMP(CDN)的产生,这是一种非典型的第二信使,它与ER-跨膜衔接蛋白STING强烈结合。构象变化由cGAMP结合的STING发生,其转移至核周区室并诱导关键转录因子IRF-3和NF-κB的活化。这导致I型干扰素的强烈诱导和促炎细胞因子如IL-6,TNF-α和IFN-γ的产生。
从治疗的角度来看,I型干扰素具有抗病毒活性,可以抑制人乙型肝炎病毒和丙型肝炎病毒复制。此外,I型干扰素和可诱导I型干扰素产生的化合物可用于治疗人类癌症。此类分子可能用作具有多种活性途径的抗癌剂。干扰素可直接抑制人肿瘤细胞增殖,并可与各种批准的化学治疗剂协同作用。I型干扰素可通过诱导适应性和先天性免疫细胞的活化而显着增强抗肿瘤免疫应答。最后,通过调节与组织重塑相关的酶表达,干扰素可以抑制肿瘤侵袭性。
STING被认为是cGAS-STING-IFN级联中的关键衔接蛋白,同时STING在先天免疫系统针对肿瘤的激活过程中的作用也被认清。Xiang Zhou等人 (STING-mediated DNA sensing in cancer immunotherapy,Science China Life Sciences,Vol.60,No.6,pp563-574)认为,虽然STING已被证明是细胞溶质DNA触发的先天免疫激活所必需的,但从各种研究中获得的积累证据表明,可以观察到STING相关信号在肿瘤发生中的内在相关性。最近的研究表明,某些抗原呈递细胞(如肿瘤浸润的树突细胞)的细胞质中存在肿瘤来源的DNA,可能是通过肿瘤细胞应激或细胞死亡产生的。已知该肿瘤衍生的DNA激活cGAS,其导致已经显示激活STING的环核苷酸的产生,导致产生相关的1型干扰素如干扰素β(Woo,SR等人,Immunity(2014)41:830-842)。STING的刺激和产生的下游信号传导途径也可能有助于效应T细胞募集到发炎的肿瘤微环境中(Woo,S.R.Trends in Immunol(2015)36:250-256)。肿瘤微环境中的STING活化可诱导适应性免疫应答,从而导致抗肿瘤活性。因此,在那些STING缺陷的肿瘤中,通过激活抗原呈递细胞和树突细胞(APC和DC)以及诱导适应性免疫应答,对这些肿瘤仍具有抗肿瘤活性。随着越来越多的数据显示,cGAS-STING细胞溶质DNA感觉途径具有诱导I型干扰素的显着能力,STING活化剂的发展迅速在今天的抗肿瘤治疗领域中占据重要地位。此外,使用免疫刺激佐剂,特别是STING的激动和非激动配体的几项临床试验已经揭示了它们不仅作为疫苗佐剂而且作为抗肿瘤剂的治疗潜力。Xiang Zhou等人总结了最近的发现,这些发现已经指出STING途径是在肿瘤环境中驱动I型干扰素产生的先天免疫传感机制。更好地理解该途径可指导进一步开发治疗癌症的新型免疫治疗策略。
由于容易在体内水解和非常低的渗透性,天然的环二核苷酸(CDN)并不适合临床开发。Aduro公司通过对天然的环二核苷酸的结构修饰,硫代磷酸酯替代磷酸酯获得了成药性更高的化合物ADU-S100。
将ADU-S00注射到B16黑色素瘤和4T1乳腺癌肿块,不仅导致明显的肿瘤抑制作用直至肿瘤消失,同时也诱导免疫系统持久的抗原特异性T细胞免疫,造成动物其它部位未注射药物的肿瘤生长也受到抑制。经肿瘤内注射后,约50%的治疗动物无肿瘤并存活超过150天(Cell Reports(2018)25,3074-3085)。此外,他们完全受到保护而免受第二次肿瘤重新攻击。这些临床前研究表明,肿瘤局部治疗诱导的全身免疫能有效诱导远端肿瘤消退。因此,间接作用可促进全身性抗肿瘤活性。
与天然CDN相比较,虽然ADU-S100的体内稳定性有很大的提高,但在给药后也仅几秒钟仍可检测到。因此开发更加稳定的新型小分子STING激动剂,有着重要的意义。
国际专利申请WO2014/093936、WO2014/189805、WO2013/185052公开了某些环状二核苷酸以及它们经由活化STING而诱导免疫应答的用途。
国际专利申请WO2017/175156公开了作为STING的调节剂的杂环酰胺类及其制备和医药用途。
仍然需要用于免疫策略的改进的化合物以治疗可能难以用传统治疗方法治疗的疾病(诸如癌症)。
