Abstract: The unmet need for the development of effective drugs to treat Alzheimer's disease
has been steadily growing, representing a major challenge in drug discovery. In this context,
drug repurposing, namely the identification of novel therapeutic indications for approved
or investigational compounds, can be seen as an attractive attempt to obtain new medications
reducing both the time and the economic burden usually required for research and
development programs. In the last years, several classes of drugs have evidenced promising
beneficial effects in neurodegenerative diseases, and for some of them, preliminary clinical
trials have been started. This review aims to illustrate some of the most recent examples of
drugs reprofiled for Alzheimer’s disease, considering not only the finding of new uses for existing
drugs but also the new hypotheses on disease pathogenesis that could promote previously
unconsidered therapeutic regimens. Moreover, some examples of structural modifications
performed on existing drugs in order to obtain multifunctional compounds will also be
described.
