Abstract: Compounds containing two mono- or disubstituted triazine rings covalently linked by an organic linker, but not linked directly to each other, may be used to treat autoimmune diseases. Autoimmune diseases which are amenable to treatment with compounds of this invention include rheumatoid arthritis, systemic lupus erythematosus (SLE), idiopathic (immune) thrombocytopenia (ITP), glomerulonephritis and vasculitis. The present invention also relates to reducing drug toxicity which often accompanies traditional therapies for autoimmune diseases. The compounds may also be used to bind antibody in vitro or ex vivo.

Abstract: The present invention describes new compounds which are useful for binding to the tail or Fc portion of immunoglobulins and so have utility in those applications which require the non-covalent binding interaction of a molecule with the Fc portion of immunoglobulins. Such applications include the detection and purification of immunoglobulins as well as the treatment of certain autoimmune diseases.
