Definitions

  • the present application relates to a class of compounds that can be used for coupling reactions and their conjugates, methods for preparing the compounds and conjugates, pharmaceutical compositions of the conjugates, and applications of the conjugates in treating tumor-related diseases.
  • ADCs Antibody-drug conjugates
  • ADCs are made by coupling monoclonal antibody drugs targeting specific antigens and small molecule cytotoxic drugs through linkers. They have both the powerful killing effect of traditional small molecule chemotherapy and the tumor targeting of antibody drugs.
  • Zynlonta As of the approval of Zynlonta in April 2021, 12 ADC drugs have been approved for marketing worldwide, including 7 for the treatment of hematological tumors and 5 for the treatment of solid tumors.
  • Antibody-drug conjugates consist of antibodies, linkers, and payloads.
  • the conjugation methods of antibodies and drug-linkers (payload-linkers) are mainly divided into non-site-specific conjugation and site-specific conjugation.
  • non-site-specific conjugation methods were used, mainly lysine conjugation and cysteine conjugation.
  • the drug was directly conjugated to the amino acid residues on the antibody by chemical methods, without involving the transformation or modification of the antibody.
  • the number of conjugated toxin molecules and the conjugation sites could not be determined, and the uniformity was poor.
  • the currently commonly used site-specific conjugation method is to perform specific conjugation through genetic engineering sites or special connectors to achieve more uniform conjugation, which can achieve the connection of cytotoxins at specific sites.
  • Antibody-drug conjugates produced by site-specific conjugation can reduce the fluctuations in efficacy, pharmacokinetics, and CMC quality control caused by different conjugation sites and the number of conjugations.
  • the common site-specific coupling methods include THIOMAB technology, non-natural amino acid coupling technology, glutamine enzymatic coupling technology, Sortase transpeptidase coupling technology and ThioBridge technology.
  • THIOMAB technology non-natural amino acid coupling technology
  • glutamine enzymatic coupling technology glutamine enzymatic coupling technology
  • Sortase transpeptidase coupling technology ThioBridge technology.
  • the modification of antibodies by antibody engineering or enzymatic coupling may have a certain impact on the structural stability of antibodies, and at the same time have certain requirements for CMC.
  • some ThioBridge technologies that use chemical coupling also have certain defects.
  • DBM dibromomaleimides
  • DBM dibromomaleimides
  • other thiol-containing biological groups undergo replacement effects, which are unstable in plasma, resulting in reduced efficacy and increased toxic side effects (Chem.-Eur.J., 2019, 25, 43-59.). Therefore, the development of new linker structures is still of great significance

Description

可用于偶联反应的化合物及其偶联物
本申请是以CN申请号为202211509417.1、申请日为2022年11月29日的申请,CN申请号为202211536550.6、申请日为2022年12月2日的申请,和CN申请号为202211573193.0、申请日为2022年12月8日的申请为基础,并主张它们的优先权,这些CN申请的公开内容在此作为整体引入本申请中。
技术领域
本申请涉及一类可用于偶联反应的化合物及其偶联物、所述化合物和偶联物的制备方法、所述偶联物的药物组合物以及所述偶联物在治疗肿瘤相关疾病中的应用。
背景技术
近年来,抗体偶联药物是肿瘤精准治疗的热门方向之一,为肿瘤治疗带来希望。抗体偶联药物(Antibody-Drug Conjugates,ADC)由靶向特异性抗原的单克隆抗体药物和小分子细胞毒药物通过连接子偶联而成,兼具传统小分子化疗的强大杀伤效应及抗体药物的肿瘤靶向性。截止到2021年04月Zynlonta的批准,全球已有12款ADC药物获批上市,其中7款用于治疗血液系统肿瘤,5款用于治疗实体瘤。
抗体偶联药物由抗体、linker及payload组成。抗体和药物-连接体(payload-linker)的偶联方法主要分为非定点偶联和定点偶联。早期使用的是非定点偶联法,主要由赖氨酸偶联和半胱氨酸偶联,利用化学方法直接将药物与抗体上氨基酸残基进行偶联,不涉及抗体的改造或修饰,其偶联的毒素分子个数和偶联位点都不能确定,均一性欠佳。目前常用的定点偶联方式即通过基因工程位点或者特殊的连接头进行特异性偶联,实现更均一地偶联,能在特定位点实现细胞毒素的连接。定点偶联生产的抗体偶联药物,可以减少因偶联位点和偶联个数不同而造成药效、药代以及CMC质控的波动。
目前常见的定点偶联方式THIOMAB技术、非天然氨基酸偶联技术、谷氨酰胺酶促偶联技术、Sortase转肽酶偶联技术以及ThioBridge技术等。其中,利用抗体工程化或者酶促偶联,对抗体的改造修饰,可能会对抗体的结构稳定性有一定影响,同时对CMC有一定要求。另外利用化学偶联的部分ThioBridge技术也有一定的缺陷,例如DBM(dibromomaleimides)类连接子和其他含巯基的生物基团发生置换作用,而在血浆中不稳定,造成药效降低,毒副作用增加(Chem.-Eur.J.,2019,25,43-59.)。因此,开发新型的连接子结构对于研发出具有良好药效及安全性的抗体偶联药物仍具有重要意义。
发明内容
本申请的一个目的在于提供用于化学偶联的新型连接子,该类连接子反应活性高,偶联条件温和、操作简便,可以实现定点偶联,得到的生物活性偶联物均一性和血浆稳定性较好,体内外药效明确。

如本文中所使用,术语“杂环基”、“杂环”是指其中至少一个环原子是选自N、O和S的杂原子且其余环原子是C的饱和或部分不饱和的(即在环内具有一个或多个双键和/或三键)环状基团。例如,“5-12元杂环(基)”是具有4-11个(如2、3、4、5、6、7、8或9个)环碳原子和一个或多个(例如1个、2个、3个或4个)独立地选自N、O和S的杂原子的饱和或部分不饱和杂环基。“5-12元含氮杂环(基)”是成环原子中至少一个为N的杂环(基)。杂环基的实例包括但不限于:环氧乙烷基、氮丙啶基、氮杂环丁基(azetidinyl)、氧杂环丁基(oxetanyl)、四氢呋喃基、二氧杂环戊烯基(dioxolinyl)、吡咯烷基、吡咯烷酮基、咪唑烷基、吡唑烷基、吡咯啉基、四氢吡喃基、哌啶基、吗啉基、二噻烷基(dithianyl)、硫吗啉基、哌嗪基或三噻烷基(trithianyl)。所述杂环基可任选地被一个或多个(例如1个、2个、3个或4个)适合的取代基取代,并且可以任选地和一个或多个芳环、杂芳环形成并环结构。

如果取代基被描述为“任选地被……取代”,则取代基可(1)未被取代或(2)被取代。如果取代基的碳被描述为任选地被取代基列表中的一个或多个取代,则碳上的一个或多个氢(至存在的任何氢的程度)可单独和/或一起被独立地选择的任选的取代基替代。如果取代基的氮被描述为任选地被取代基列表中的一个或多个取代,则氮上的一个或多个氢(至存在的任何氢的程度)可各自被独立地选择的任选的取代基替代。

除非指明,否则如本文中所使用,取代基的连接点可来自取代基的任意适宜位置。

本文中可使用实线(——)、实楔形或虚楔形描绘本发明的化合物的碳-碳键。使用实线以描绘键连至不对称碳原子的键欲表明,包括该碳原子处的所有可能的立体异构体(例如,特定的对映异构体、外消旋混合物等)。使用实或虚楔形以描绘键连至不对称碳原子的键欲表明,存在所示的立体异构体。当存在于外消旋混合物中时,使用实及虚楔形以定义相对立体化学,而非绝对立体化学。除非另外指明,否则本发明的化合物意欲可以立体异构体(其包括顺式及反式异构体、光学异构体(例如R及S对映异构体)、非对映异构体、几何异构体、旋转异构体、构象异构体、阻转异构体及其混合物)的形式存在。本发明的化合物可表现一种以上类型的异构现象,且由其混合物(例如外消旋混合物及非对映异构体对)组成。

本发明的化合物的药学上可接受的盐包括其酸加成盐及碱加成盐。
适合的酸加成盐由形成药学可接受盐的酸来形成。实例包括天冬氨酸盐、苯甲酸盐、碳酸氢盐/碳酸盐、葡庚糖酸盐、葡糖酸盐、硝酸盐、乳清酸盐、棕榈酸盐及其它类似的盐。

适合的盐的综述参见Stahl及Wermuth的“Handbook of Pharmaceutical Salts:Properties,Selection,and Use”(Wiley-VCH,2002)。用于制备本发明的化合物的药学上可接受的盐的方法为本领域技术人员已知的。
如本文中所使用,术语“酯”意指衍生自本申请中各个通式化合物的酯,其包括生理上可水解的酯(可在生理条件下水解以释放游离酸或醇形式的本发明的化合物)。本发明的化合物本身也可以是酯。
本发明的化合物可以溶剂合物(优选水合物)的形式存在,其中本发明的化合物包含作为所述化合物晶格的结构要素的极性溶剂,特别是例如水、甲醇或乙醇。极性溶剂特别是水的量可以化学计量比或非化学计量比存在。
本领域技术人员会理解,由于氮需要可用的孤对电子来氧化成氧化物,因此并非所有的含氮杂环都能够形成N-氧化物;本领域技术人员会识别能够形成N-氧化物的含氮杂环。本领域技术人员还会认识到叔胺能够形成N-氧化物。用于制备杂环和叔胺的N-氧化物的合成方法是本领域技术人员熟知的,包括用过氧酸如过氧乙酸和间氯过氧苯甲酸(MCPBA)、过氧化氢、烷基过氧化氢如叔丁基过氧化氢、过硼酸钠和双环氧乙烷(dioxirane)如二甲基双环氧乙烷来氧化杂环和叔胺。这些用于制备N-氧化物的方法已在文献中得到广泛描述和综述,参见例如:T.L.Gilchrist,Comprehensive Organic Synthesis,vol.7,pp748-750;A.R.Katritzky和A.J.Boulton,Eds.,Academic Press;以及G.W.H.Cheeseman和E.S.G.Werstiuk,Advances in Heterocyclic Chemistry,vol.22,pp 390-392,A.R.Katritzky和A.J.Boulton,Eds.,Academic Press。
在本发明的范围内还包括本发明的化合物的代谢物,即在给药本发明的化合物时体内 形成的物质。这样的产物可由例如被给药的化合物的氧化、还原、水解、酰胺化、脱酰胺化、酯化、酶解等产生。因此,本发明包括本发明的化合物的代谢物,包括通过使本发明的化合物与哺乳动物接触足以产生其代谢产物的时间的方法制得的化合物。
本发明在其范围内进一步包括本发明的化合物的前药,其为自身可具有较小药理学活性或无药理学活性的本发明的化合物的某些衍生物当被给药至身体中或其上时可通过例如水解裂解转化成具有期望活性的本发明的化合物。通常这样的前药会是所述化合物的官能团衍生物,其易于在体内转化成期望的治疗活性化合物。关于前药的使用的其他信息可参见“Pro-drugs as Novel Delivery Systems”,第14卷,ACS Symposium Series(T.Higuchi及V.Stella)。本发明的前药可例如通过用本领域技术人员已知作为“前-部分(pro-moiety)(例如“Design of Prodrugs”,H.Bundgaard(Elsevier,1985)中所述)”的某些部分替代本发明的化合物中存在的适当官能团来制备。
本发明还涵盖含有保护基的本发明的化合物。在制备本发明的化合物的任何过程中,保护在任何有关分子上的敏感基团或反应基团可能是必需的和/或期望的,由此形成本发明的化合物的化学保护的形式。这可以通过常规的保护基实现,例如,在T.W.Greene&P.G.M.Wuts,Protective Groups in Organic Synthesis,John Wiley&Sons,1991中所述的那些保护基,这些参考文献通过援引加入本文。使用本领域已知的方法,在适当的后续阶段可以移除保护基。
