The Cracked Potential of Boron-containing Compounds in Alzheimer's Disease.

Abstract

Alzheimer's disease (AD) is a relevant neurodegenerative disease worldwide. Its relevancy is mainly due to its high prevalence and high global burden. Metalloids have attracted attention as their serum levels seem to differ between affected patients and healthy individuals. On the other hand, atoms of some metalloids have been included in bioactive molecules, exerting some interesting effects, mainly due to their ameliorative effects in neurodegeneration. In this sense, boron-containing compounds (BCC) have been explored to regulate or prevent neurodegeneration. As an example, boric acid has been reported as a compound with antioxidant, anti-inflammatory and neurotrophic effects. Other natural BCCs have also shown amelioration of metabolic conditions often related to increased risk of neurodegenerative maladies. However, in recent years, additional organoboron compounds have been reported as active in several processes linked to neurodegeneration and especially attractive as regulators of the origin and progression of AD. In this mini-review, some data are collected suggesting that some natural BCC could be used as preventive agents, but also the potential of some BODIPYs as tools for diagnosis and some other BCC (particularly boronic acids and pinacol boronic esters) for acting as promising therapeutic agents for AD.
