Abstract: The present invention provides compounds capable of binding to an Fc receptor and modulating Fc receptor activity comprising a core lipophilic group in the form of an Aryl zing substituted with a group rich in p-electrons. The invention further provides for a method of treating an autoimmune disease involving Fc receptor activity using such compounds. A method for obtaining a compound which modulates Fc receptor activity is also provided, the method comprising: (a) providing or designing compounds having structural characteristics to fit in the groove of the Fc?RIIa structure; and (b) screening the compounds for modulating activity on the Fc receptor.

Abstract: A soluble multimeric polypeptide or protein is disclosed that is able to inhibit interaction of leukocyte Fc? receptors (Fc?R) and immunoglobulin G (IgG). The protein or polypeptide comprises two or more Fc binding regions linked in a head to tail arrangement, at least one of which is derived from an Fc?R type receptor, and an Fc domain of an immunoglobulin which has been modified to reduce or prevent binding to the said Fc binding regions and/or to alter effector function. Also described are polynucleotide molecules encoding the polypeptide or protein and the use thereof in methods of treating a subject for an immune-complex (IC)-mediated inflammatory disease.
