Abstract:

Alzheimers disease is one of the most challenging threats to the healthcare system in society. One of the main characteristic of Alzheimers disease (AD) pathology is formation of amyloid plaques from accumulation of amyloid beta peptide. The therapeutic agents that are currently available for AD including acetylcholinesterase inhibitors (AchEIs) and the N-methyl-D-aspartate (NMDA) antagonist are focused on improving the symptoms and do not revert the progression of the disease. This limitation coupled with the burgeoning increase in the prevalence of AD and resultant impact on healthcare economics calls for more substantial treatments for AD. According to the leading amyloid hypothesis, cleavage of amyloid precursor protein to release amyloid beta peptide is the critical event in pathogenesis of Alzheimers disease. Recently treatment strategies have been focused on modifying the formation, clearance and accumulation of neurotoxic amyloid beta peptide. This article reviews different therapeutic approaches that have been investigated to target amyloid beta ranging from secretase modulators, antiaggregation agents to amyloid immunotherapy. Authors review the different novel drugs which are in clinical trials.
