Definitions

  • the present invention belongs to the field of biomedicine, and specifically relates to a class of urea compounds and a preparation method, medical use and pharmaceutical composition thereof as a novel STING inhibitor.
  • cGAS Cyclic AMP-GMP synthase
  • 2’,3’-cGAMP can specifically bind to the “V”-shaped pocket formed by the dimer of the endoplasmic reticulum protein STING (also known as TMEM173, MITA, ERIS or MPYS) (Nature, 2008, 455(7213): 674-678; Nature, 2011, 478(7370): 515-518), thereby inducing the multimerization activation of the STING protein (Cell, 2013, 154(4): 748-62).
  • STING also known as TMEM173, MITA, ERIS or MPYS
  • the multimerized STING protein transfers from the endoplasmic reticulum to the Golgi compartment, and in the process recruits downstream kinase protein TBK1 and transcription factor IRF3.
  • TBK1 catalyzes the phosphorylation of STING and IRF3 after autophosphorylation activation (Nature, 2019, 567(7748):394-398; Nature, 2019, 569(7758):718-722).
  • Phosphorylated IRF3 further dimerizes and enters the nucleus, promoting the expression of type I interferons (type I interferons) and their related immune factors (interferon stimulated genes, ISGs).
  • STING protein can also activate the NF- ⁇ B signaling pathway by recruiting TBK1 and TRAF6 molecules, promoting the expression of inflammatory factors such as TNF- ⁇ and IL-6 (J Virol, 2014, 88(10):5328-41).
  • AGS syndrome (Aicardi-Goutines syndrome) (Am J Med Genet A, 2015, 167A(2): 296-312), systemic lupus erythematosus (SLE) (Nat Rev Rheumatol, 2018, 14(4): 214-228), Bloom syndrome (J Exp Med, 2019, 216(5): 1199-1213), SAVI (S TING-associated vasculopathy with onset in infantile diseases (N Engl J Med, 2014, 371(6):507-518), skin cancer (Nat Commun, 2014, 5:5166), tumor metastasis (Nature, 2018, 553(7689):467-472), progeria (Nature, 2017, 550(7676):402-406), sepsis (Shock, 2017, 47(5):621-631),
  • H-151 is an indole STING palmitoylation inhibitor (Nature 2018, 559, 269-273; EP3556362), which can significantly improve the symptoms of ALS (Cell, 2020, 183, 636-649).
  • H-151 has significant therapeutic effects in psoriasis models (Bri J Pharmacol, 2021, 178, 4907-4922).
  • H-151 has weak STING inhibitory activity and extremely poor pharmacokinetic properties (Brit J Pharmacol, 2021, 178, 4907-4922), which severely limits its clinical application.
  • IFM Due has developed a series of H-151 derivatives (WO2021138434).
  • the inventors reported for the first time a new class of STING inhibitors that act on cyclic dinucleotide binding sites (PNAS 2021, 118 (24): e2105465118; WO2021068951A1). Unfortunately, there is no STING inhibitor to date. In short, there is an urgent clinical need to develop new STING inhibitors.

背景技术
细胞质中的DNA在固有免疫系统的激活中发挥重要作用(Curr Opin Immunol,2018,55:31-37)。cGAS(Cyclic AMP-GMP synthase)能够识别异常暴露的胞浆DNA,并以ATP和GTP为底物催化合成2’,3’-cGAMP(2’-3’/3’-5’cyclic GMP-AMP)。2’,3’-cGAMP能特异性地结合到内质网蛋白STING(也被称为TMEM173,MITA,ERIS或MPYS)二聚体形成的“V”形口袋内(Nature,2008,455(7213):674-678;Nature,2011,478(7370):515-518),进而诱导STING蛋白的多聚化激活(Cell,2013,154(4):748-62)。多聚化的STING蛋白由内质网向高尔基体室转移,并在此过程中招募下游的激酶蛋白TBK1和转录因子IRF3,TBK1在自磷酸化激活后催化STING和IRF3的磷酸化(Nature,2019,567(7748):394-398;Nature,2019,569(7758):718-722)。磷酸化的IRF3进一步二聚化入核,促进I型干扰素(type I interferons)及其相关免疫因子的表达(interferon stimulated genes,ISGs)。此外,STING蛋白也能通过招募TBK1和TRAF6分子,激活NF-κB信号通路,促进TNF-α和IL-6等炎症因子的表达(J Virol,2014,88(10):5328-41)。
STING通路的异常激活会导致自身免疫疾病和炎症疾病的发生发展(Nature Immunology,2017,18(7):716-724)。与STING信号通路异常激活相关的疾病包括:AGS综合症(Aicardi-Goutières syndrome)(Am J Med Genet A,2015,167A(2):296-312)、系统性红斑狼疮(systemic lupus erythematosus,SLE)(Nat Rev Rheumatol,2018,14(4):214-228)、Bloom综合症(J Exp Med,2019,216(5):1199-1213)、SAVI(STING-associated vasculopathy with onset in infancy)疾病(N Engl J Med,2014,371(6):507-518)、皮肤癌(Nat Commun,2014,5:5166)、肿瘤转移(Nature,2018,553(7689):467-472)、早衰症(Nature,2017,550(7676):402-406)、脓毒症(Shock,2017,47(5):621-631)、急性胰腺炎(Gastroenterology,2018,154(6):1822-1835)、帕金森疾病(Nature,2018,561(7722):258-262)、非酒精性脂肪肝及肝纤维化(Gastroenterology,2018,155(6):1971-1984;Proceedings of the National Academy of Sciences,2017,114(46):12196-12201)、肺炎(Nature Communications,2018,9(1))、慢性肾炎及肾纤维化(Cell Metabolism,2019,DOI:10.1016/j.cmet.2019.08.003)、渐冻症(Cell,2020,183,636-649)、银屑病(Brit J Pharmacol,2021,178,4907-4922)和缺血性再灌注损伤(Nature Medicine,2017,23(12):1481-1487)等,而抑制STING信号通路的激活可能会改善上述疾病的发生发展。总之,STING抑制剂具有广泛的临床应用前景。
目前,文献报道的STING抑制剂的种类屈指可数(Cell Reports 2018,25,3405-3421;ACS Med.Chem.Lett.2019,10(1),92-97;Nature 2018,559,269-273;EP3556362;PNAS 2021,118(24):e2105465118)。H-151是一个吲哚类STING棕榈酰化抑制剂(Nature 2018,559,269-273;EP3556362),其可显著改善渐冻症的症状(Cell,2020,183,636-649)。本发明人的研究首次发现,H-151的皮肤外用制剂在银屑病模型上具有显著疗效(Bri J Pharmacol,2021,178,4907-4922)。然而,H-151的STING抑制活性较弱,且药代动力学性质极差(Brit J Pharmacol,2021,178,4907-4922),这严重限制了其临床应用。最近,IFM Due公司发展了一系列H-151的衍生物(WO2021138434)。此外,本发明人首次报道了一类作用于环二核苷酸结合位点的新型STING抑制剂(PNAS 2021,118(24):e2105465118;WO2021068951A1)。令人遗憾的是,迄今尚无任何STING抑制 剂进入临床研究阶段。总之,研制新型STING抑制剂具有非常迫切的临床需求。
另一方面,尽管已获批上市的含氟药物的数量达到了数百种,然而含有三氟甲硫基的药物很少见,尤其是三氟甲硫基团尚未出现在现有STING抑制剂的结构中。

(1)文献报道的STING抑制剂H-151作用在STING的棕榈酰化位点的疏水口袋(Nature 2018,559,269-273),但H-151的STING抑制活性较弱,且代谢稳定性较差,口服生物利用度极低(Brit J Pharmacol,2021,178,4907-4922),这严重影响了其成药性。与H-151相比,本发明的脲类化合物的STING抑制活性有了显著提高,且同时具有显著改善的代谢稳定性,因而具有更好的成药性。
(2)本发明设计的特定结构脲类化合物,通过体内实验发现该结构中含有三氟甲硫基团相比较不含三氟甲硫基团类似结构化合物具有更加优异的体内疗效。

化合物对THP1-Dual细胞STING信号通路的抑制活性评价
实验原理:THP1-Dual是商品化的NF-κB及IRF信号通路的双报告基因检测细胞。其中,通过检测分泌的荧光素酶,可以评价IRF信号通路的转录活性。同时,这株细胞表达cGAS和STING蛋白,导入外源双链DNA可以激活cGAS-STING信号通路,从而增强IRF的转录活性。因此,利用转染外源HT-DNA来激活细胞内的cGAS-STING-IRF信号通路,加入化合物干预STING信号通路后,通过检测分泌的荧光素酶来评价化合物对STING的抑制活性。
实验试剂与材料:热灭活血清(Biological Industries),1640培养基(Biological Industries),青霉素-链霉素双抗(Biological Industries),THP1-DualTMCells(InvivoGen),HT-DNA(Sigma Aldrich,配制为2.5mg/mL的储存液),Opti-MEM(Gibco),Lipo6000(碧云天),QUANTI-LucTM(InvivoGen)。
实验方法:(1)细胞种板:将生长状态良好的THP1-Dual细胞离心、重悬并计数。取部分细胞与预先配制好的HT-DNA工作液(例如:将含有1μg的HT-DNA储存液与2μL的Lipo6000混合于0.5mL的Opti-MEM中,室温静置10min即可使用)混合,配制成HT-DNA浓度为0.5μg/mL,细胞浓度为80万个/mL的培养基溶液,取100μL加入到96孔板中,为实验孔;并向对照孔中加入不含HT-DNA的相应细胞溶液。(2)细胞给药:将待测化合物配制成10mM的储存液,并用培养基梯度稀释成20、4、0.8、 0.16、0.008、0.0064、0.00128μM的药液,并向实验孔中依次加入100μL药液,对照孔和模型孔加入100μL培养基。放入培养箱中培养16~18h后检测。(3)检测:将QUANTI-LucTM粉末按说明书用纯化水配制成检测液,分装后放于4℃保存。向白色不透光的384孔板中加入10μL的检测液。将96孔板取出,并用96孔板离心机1000rpm离心1min后,依次吸取4μL的上清液,加入到加有检测液的96孔板中,利用酶标仪检测化学发光。(4)数据处理:固定浓度下化合物的抑制率按以下公式计算:某浓度下化合物的抑制率=1-(某浓度下化合物孔的化学发光值-对照孔的化学发光值)/(模型孔的化学发光值-对照孔的化学发光值)×100%;再根据化合物各个浓度下的抑制率拟合出曲线,计算出化合物的半数抑制率(IC50值)。
实验结果:化合物对THP-1Dual细胞STING信号通路的抑制活性结果如表2和表3所示。

STING抑制剂化合物对人肝微粒体的代谢稳定性研究
人肝微粒体代谢稳定性评价是药物研发中临床前评价候选化合物药代动力学性质的重要手段,该实验参照文献方法(Pharmacol Rep.2006,58,453-472)进行。
实验温孵体系(体积为250μL,n=3)包括肝微粒体、受试物工作溶液和磷酸盐缓冲液。将温孵体系于37℃共孵育一个小时,加入NADPH溶液后计时开始,每个时间点以加入终止液终止反应,取样间点为0,5,15,30,45min,共5个点。对照药采用Diclofenac。阴性对照不加NADPH,取样时间点为0,60min。用LC-MS/MS进行分析,通过受试物剩余量的百分率的自然对数与时间作图测得斜率的绝对值k,按以下公式进行计算:T1/2(半衰期)=ln2/k=0.693/k。实验结果如表4所示。
表4、化合物对人肝微粒体的代谢稳定性

实验结果(表4)表明,H-151被人肝微粒体快速代谢,其半衰期T1/2只有8.81min,表明其代谢稳定性较差。而本发明化合物的人肝微粒体代谢稳定性有非常显著的提升。本发明的其他一些化合物也具有很好的人肝微粒体代谢稳定性。

实验动物:Balb/c雌性小鼠,8周龄,购自浙江维通利华实验动物有限公司。
受试药物配置:将7.2g PEG400加热至55~60℃,加入200mg受试药搅拌,并使用超声波清洗器超声溶解,期间反复颠倒混匀数次,溶解后将2.8g PEG3350加热至55~60℃溶解后与混合有受试药的PEG400混匀,分装成1g/管,配制成2%的受试药软膏,小鼠背部涂抹0.2g/只。同时配制不含化合物的对照软膏。
造模给药:将小鼠随机分为空白组、模型组、I-1组(涂抹2%的I-1软膏)和I-176组(涂抹2%的I-176软膏),每组5只。小鼠背部脱毛,露出2cm×3cm的皮肤区域。脱毛后适应2天。5%咪喹莫特(Imiquimod,IMQ)乳膏50mg/只涂抹后背,每天一次,造模7天。同时给予给药组相应受试药软膏,对照组以及模型组动物给予对照软膏,0.2g/只,每天1次,共给药7天。每天称重,拍摄后背照片并进行PASI(银屑病皮损面积和严重程度指数)打分。
实验结果(图1)表明,涂抹咪喹莫特乳膏后,小鼠背部显著出现红斑、增厚和鳞屑等银屑病样病理表型,而涂抹化合物I-1和I-176软膏后,可以显著改善这些病理特征。同时,根据PASI打分(图2)也可以看出,化合物I-1和I-116可以显著减少模型小鼠后背银屑病样的炎症损伤、皮肤增厚和鳞屑生成。说明这些化合物具有显著的免疫调节功效,可用于银屑病的治疗,进一步提示其可用于预防和治疗感染性疾病、炎性疾病、自身免疫性疾病、代谢性疾病、器官纤维化疾病、心脑血管疾病、呼吸系统疾病、中枢神经系统疾病、癌症或癌前期综合征等疾病。本发明的其他化合物也具有类似的疗效。
