TTP488 is an antagonist at the Receptor for Advanced Glycation End products, is evaluated as a potential treatment for patients with mild-to-moderate Alzheimer's disease (AD).Target: RAGEin vitro: TTP488 is an orally active, centrally acting antagonist of RAGE-RAGE ligand interaction. Chronic oral dosing of TTP488 in AD transgenic mice led to a reduction of amyloid load in the brain, improves performance on behavioral testing and normalization of electrophysiological recordings from hippocampal slices.[1]in vivo: The small molecule RAGE antagonist, TTP488, is developed by Trans-Tech Pharma. The TTP488 or control peptide is administered i.p. daily at a dose of 100 mcg/d.[3] Successful use of the RAGE inhibitor TTP488 in Phase II testing has led to a Phase III clinical trial for AD patients.[2]
