Traditionally, drug design programs are focused on optimizing the specificity of lead compounds against a carefully selected drug target. Disappointingly, this approach to discover a “magic bullet” drug has not met with the expected success for CNS disorders. Transcriptomics and proteomic profiling of neurodegenerative diseases have indicated that they are poly-etiological in origin and that the processes leading to neuronal death are multifactorial. An emerging concept is the design of drug ligands that modulate multiple drug targets identified for a particular disease. In this review we explore some examples of multifunctional drugs which may be useful in the treatment of neurodegenerative diseases, such as Alzheimers and Parkinsons disease.
