Definitions

  • the present invention belongs to the field of medicine, and relates to 2-substituted piperidine derivatives, preparation methods thereof, pharmaceutical compositions comprising the compounds, and medical uses thereof.
  • the complement system is a part of the innate immunosurveillance, playing a critical role in eliminating pathogens and in the tissue homeostasis.
  • the complement cascade can be activated by three different pathways including classical (CP) , lectin (LP) , and alternative pathway (AP) .
  • the CP and LP are initiated on target surfaces by immune complexes and binding of mannan-binding lectin or ficolin to a particular of microbial sugar moiety pattern, respectively.
  • the AP does not require specific initiation.
  • the AP cascade is initiated by spontaneous hydrolysis of C3 (tick-over) and subsequent deposition of C3b on an activating surface.
  • the three complement activation pathways converge on two major events, C3 cleavage and C5 cleavage.
  • C3 convertases split C3 into C3a and C3b.
  • C3b forms additional AP C3 convertases (amplification) as well as C5 convertases.
  • C5 convertases cleave C5 into C5a and C5b.
  • the produced C5b initiates the formation of the C5b-9 membrane attack complex (MAC) with C6-C9, leading to lysis of bacteria and cells by insertion into a membrane.
  • the split products C3a and C5a function as anaphylatoxins to promote pro-inflammatory responses through activation and chemotaxis of leukocytes.
  • C3b also plays a key role in removing bacteria and cellular waste such as immune complexes and apoptotic cells through promoting phagocytosis by opsonization.
  • the down-stream effects of mannan-induced lectin complement pathway activation depend quantitatively on alternative pathway amplification. Mol. Immunol. 47, 373–380. https: //doi. org/10.1016/j. molimm. 2009.09.005 ) .
  • the spontaneous activated C3 forms C3 convertase by binding with factor B (FB) .
  • C3b and Bb After cleavage of FB into Bb by factor D, C3b and Bb generate the AP C3 convertase (C3bBb) .
  • the newly formed C3bBb cleaves more C3 to generate more AP C3 convertases, leading to the amplification of complement cascade.
  • This invention aims to provide compounds which modulate Factor B and treat disorders associated with the dysregulation of the Complement pathway.
