Background: The treatment and diagnosis of Alzheimer’s Disease (AD) are twoof the most urgent goals for research around the world. The cognitive decline is generallyassociated with the elevated levels of extracellular senile plaques, intracellular neurofibril-lary tangles (NFTs), and with a progressive shutdown of the cholinergic basal forebrainneurons transmission. Even if several key targets are under fervent investigation in the cureof AD, till now, the only approved therapeutic strategy is the treatment of symptoms byusing cholinesterases inhibitors. It has been demonstrated that both acetylcholinesterase(AChE) and butyrylcholinesterase (BuChE) enzymes are not only responsible of acetylcho-line levels, but also play an pivotal role in A -aggregation during the early stages of senileplaque formation. On the other hand the difficult management of AD is also related to ef-fective diagnostic methods and efficient assays for the study of pathological features. Insuch complex a wide framework, heterocyclic molecules are essential backbone to buildnew and selective drugs as well as diagnostic probes. Methods: The goal of this review is to examine a selected sample of relevant applications of five- and six-membered heterocycles in AD's therapeutic approaches. Results: Concerning the research on AD, the contribution of heterocyclic compounds is huge and here we report some representative examples. The review is organized in two main sections focused on five and six-membered het- erocycles. The analyzed cases have been classified on the base of the structural features of molecules, taking into account the progressive increase in heteroatoms number. Conclusion: The discovery of an effective therapy or a diagnostic protocol for AD is still far, but consistent improvements are underway and contribution of heterocyc- lic compounds will be consistent and hopefully determinant.
