Definitions

  • the invention belongs to the field of medical technology and relates to the crystallization of a bridged heterocyclic substituted benzoic acid derivative or its salt and its preparation method, specifically to the crystallization of the compound of formula (II), the hydrochloride of the compound of formula (II) and its crystallization , and preparation method thereof.
  • the complement system is an important component of the body's innate immunity against infections such as foreign pathogens, bacteria, and parasites.
  • the complement system is also an important component of the connection between innate immunity and adaptive immunity.
  • Complement consists of plasma proteins, including soluble proteins, membrane-bound proteins and complement receptors. It is mainly produced by membrane proteins expressed in the liver or cell surface and plays a role in plasma, tissues or cells.
  • the complement system is mainly activated through three pathways: the classical pathway (CP), the lectin pathway (LP), and the alternative pathway (AP).
  • the AP pathway always maintains a low-level activation state to monitor the invasion status of foreign pathogens at any time.
  • Complement proteins are distributed on the surface of apoptotic cells, and complement activation is strictly regulated and is only used to clear apoptotic cells without further activating other innate or adaptive immune responses.
  • the complement system In the case of infection by foreign pathogens, the complement system is fully activated, producing inflammatory responses, opsonization or phagocytosis, etc., destroying the pathogens and ultimately activating the adaptive immune response.
  • Both complement inefficiency and overstimulation can be harmful and are associated with increased susceptibility to infections or non-communicable diseases, such as autoimmune diseases, chronic inflammation, thrombotic microangiopathies, transplant rejection and tumors.
  • Complement factor B acts on the AP pathway. Inhibiting Factor B activity can prevent the activation of the API pathway without interfering with the CP and LP pathways, and can avoid increasing the risk of infection due to complement system inhibition.
  • Factor B inhibitors There are currently no small molecule Factor B inhibitors on the market.
  • Novartis' factor B inhibitor LNP023 is in the clinical phase III research stage and is used for the treatment of PNH, IgAN, C3G and other diseases. Therefore, it is necessary to develop new small molecule inhibitors of the complement system Factor B, increase clinical research and verification, and use them in the treatment of various diseases caused by complement abnormalities to provide new treatment methods for unmet clinical needs.

背景技术
补体***是人体抵抗外源病原体、细菌和寄生虫等感染的重要的先天免疫组成,同时补体***也是先天免疫与适应性免疫衔接的重要组成。补体由血浆蛋白组成,包括可溶性蛋白、膜结合性蛋白和补体受体,主要由肝脏或细胞表面表达的膜蛋白产生,在血浆,组织或细胞内发挥作用。补体***主要通过三条通路激活:经典通路(classical pathway,CP)、凝集素通路(lectin pathway,LP)以及旁路通路(alternative pathway,AP)。
健康个体的正常生理状态下,AP通路一直保持低水平的活化状态以随时监测外来病原体入侵状态。补体蛋白分布在凋亡细胞表面,补体激活受到严格的调节,仅仅用于清除凋亡的细胞,而不会进一步激活其他先天免疫或适应性免疫反应。在外来病原体感染的情况下,补体***被全面激活,产生炎性反应,调理作用或吞噬作用等,破坏病原体并最终激活适应性免疫反应。补体的低效和过度刺激都可能对人体有害,并且与感染或非传染性疾病的易感性增加有关,比如自身免疫疾病,慢性炎症,血栓性微血管病,移植排斥和肿瘤等。
补体因子B(Factor B)作用于AP通路,抑制Factor B活性能够阻止API通路激活,且不干扰CP和LP通路,能够避免因补体***抑制增加感染风险。目前尚无小分子Factor B抑制剂上市,Novartis的factor B抑制剂LNP023处于临床III期研究阶段,用于PNH、IgAN、C3G等疾病的治疗。因此,有必要开发新型补体***Factor B小分子抑制剂,增加临床研究和验证并用于补体异常导致的各种疾病的治疗,为未满足临床需求提供新的治疗手段。
