Imaging agents of formulas (I)-(V) and methods for detecting neurological disorders comprising administering to a patient in need compounds of formulas (I)-(V) capable of binding to tau proteins and β-amyloid peptides are presented herein. The invention also relates to methods of imaging Aβ and tau aggregates comprising introducing a detectable quantity of pharmaceutical formulation comprising a radiolabeled compound of formulas (I)-(V) and detecting the labeled compound associated with amyloid deposits and/or tau proteins in a patient. These methods and compositions enable preclinical diagnosis and monitoring progression of AD and other neurological disorders.

Novel benzimidazole derivatives are synthesized by the reaction of 2-substituted 1,3-bis(dimethyl-amino)-trimethinium salts with 2-aminobenzimidazole in the presence of acetic acid or triethylamine in acetonitrile as the solvent. The ultraviolet spectral behavior of these compounds is examined in DMSO. (C) 2014 Elsevier Ltd. All rights reserved.
