RESUMO
Despite the applicability of histone deacetylase inhibitors (HDACis) for cancer treatment, several works in the literature have shown that these inhibitors can be used in several other diseases, such as neurodegenerative diseases (NDs). This review begins by discussing the signaling pathways of HDACs, focused on the context of NDs, presenting a discussion about the pharmacophoric features of HDACis and crystal structure analysis and discussing interesting case studies from the literature about the development of HDACis. Additionally, a discussion about the consequences of isoform-selective inhibition vs pan-HDACis on neurotoxic effects and clinical trial investigations of HDACis for NDs is also presented. Finally, we describe our perspective related to the future use of these inhibitors in the pharmacotherapy of NDs.
