  • Patent number: 10966945
    Abstract: This patent pertains to selective inhibition of assembly of the membrane attack complex of complement by use of less than 1 kDa molecular weight forms of the aurin tricarboxylic acid synthetic complex (ATAC), and their derivatives. It further pertains to the use of these materials to treat human conditions where there is evidence of self destruction of host tissue by the membrane attack complex. These diseases include, but are not limited to, Alzheimer disease, age related macular degeneration, and atherosclerosis.
