Definitions

  • the disclosure relates to the inhibition of the complement alternative pathway, and particularly to inhibition of factor B. It also relates to treatment of patients suffering from conditions and diseases associated with complement alternative pathway activation.
  • the complement system is a crucial component of the innate immunity system and comprises a group of proteins that are normally present in an inactive state. These proteins are organized in three activation pathways: the classical, the lectin, and the alternative pathways (V. M. Holers, In Clinical Immunology: Principles and Practice, ed. R.R. Rich, Mosby Press; 1996, 363-391). Molecules from microorganisms, antibodies or cellular components can activate these pathways resulting in the formation of protease complexes known as the C3-convertase and the C5-convertase.
  • the classical pathway is a calcium/magnesium-dependent cascade, which is normally activated by the formation of antigen-antibody complexes.
  • the alternative pathway is a magnesiumdependent cascade that is activated by deposition and activation of C3 on certain susceptible surfaces (e.g., cell wall polysaccharides of yeast and bacteria, and certain biopolymer materials).
  • Factor B is a suitable target for the inhibition of this amplification of the complement pathways because its plasma concentration in humans is typically about 200 pg/mL (or about 2 pM), and it has been shown to be a critical enzyme for activation of the alternative complement pathway (P.H. Lesavre and H.J. Muller-Eberhard. J. Exp. Med., 1978; 148: 1498-1510; J.E. Volanakis et al., New Eng. J. Med., 1985; 312:395-401).
  • the present disclosure provides compounds that modulate, and/or inhibit, activation of the alternative complement pathway.
  • the present disclosure provides compounds that modulate, and/or inhibit, factor B activity and/or factor B mediated complement pathway activation.
  • factor B modulators are preferably high affinity factor B inhibitors that inhibit the catalytic activity of complement factor B, such as primate factor B and particularly human factor B.

  • a method of treating age-related macular degeneration comprising administering to a subject in need thereof an effective amount of a composition comprising a compound of Formula (I), or a pharmaceutically acceptable salt or a stereoisomer or an isotopically labeled compound thereof.

  • Macular degeneration is a clinical term that is used to describe a family of diseases that are characterized by a progressive loss of central vision associated with abnormalities of Bruch’s membrane, the choroid, the neural retina and/or the retinal pigment epithelium.
  • the macula lutea which is about 1 to % cm in diameter.
  • the macula provides detailed vision, particularly in the center (the fovea), because the cones are higher in density and because of the high ratio of ganglion cells to photoreceptor cells. Blood vessels, ganglion cells, inner nuclear layer and cells, and the plexiform layers are all displaced to the side (rather than resting above the photoreceptor cells), thereby allowing light a more direct path to the cones.

  • Age-related macular degeneration is associated with progressive loss of visual acuity in the central portion of the visual field, changes in color vision, and abnormal dark adaptation and sensitivity.
  • Two principal clinical manifestations of AMD have been described as the dry, or atrophic, form and the neovascular, or exudative, form.
  • the dry form is associated with atrophic cell death of the central retina or macula, which is required for fine vision used for activities such as reading, driving or recognizing faces.
  • About 10-20% of these AMD patients progress to the second form of AMD, known as neovascular AMD (also referred to as wet AMD).
  • Neovascular AMD is characterized by the abnormal growth of blood vessels under the macula and vascular leakage, resulting in displacement of the retina, hemorrhage and scarring. This results in a deterioration of sight over a period of weeks to years.
  • Neovascular AMD cases originate from Intermediate or advanced dry AMD. The neovascular form accounts for 85% of legal blindness due to AMD. In neovascular AMD, as the abnormal blood vessels leak fluid and blood, scar tissue is formed that destroys the central retina.
