Abstract

Provided are methods to detect of modulators of the Receptor for Advanced Glycated Endproducts (RAGE). The invention comprises a method for detection of RAGE
modulators comprising: adsorbing a RAGE ligand onto a solid surface; adding a compound of interest and a protein comprising RAGE or fragment thereof, to the preadsorbed ligand;
adding an antibody which binds to RAGE or fragment thereof and a secondary antibody which binds to the anti-RAGE antibody; measuring the secondary antibody bound to the anti-RAGE antibody; and comparing the amount of RAGE bound to the ligand in the presence of varying amounts of the compound of interest. In an embodiment, the fragment of RAGE is sRAGE. In one aspect, the invention use of compounds detected by the method for treatment of AGE-related syndromes including complications associated with diabetes, kidney failure, lupus nephritis or inflammatory lupus nephritis, amyloidoses, Alzheimer's disease, cancer, inflammation, and erectile dysfunction.
