Deciphering Drug Targets for Alzheimer’s Disease

Abstract

Alzheimer’s disease (AD) is a chronic neurodegenerative disorder characterized by progressive degeneration in the brain and shrinking (atrophy) of the brain size with the association of multiple factors/targets. The traditional “one medicine, one target” approach tends to be insufficient due to the complexity of AD. Till now, no established strategy for the treatment of AD is available. Therefore, it is of prime importance to catch the promising targets from the reported several targets. Target fishing here plays a pivotal role in a drug discovery without prior knowledge about their role in AD. Computational approaches are now considered an integral component of drug discovery with exceptional theoretical assumptions over the decades. Ligand and structure-based in silico approaches are able to provide a rational solution to the answer of target fishing. With this background, the objective of the book chapter was mainly to describe the powerful in silico tools for the optimization of the target based on literature reports and in silico tools available for target prioritization.
