摘要

The present paper provides the first integrated assessment of the capacity of the flavonol, fisetin, to induce hormetic dose responses. Fisetin was shown to induce hormetic dose responses in cellular and in vivo animal model systems affecting a broad range of endpoints of potential therapeutic and public health significance across the entire lifespan. Fisetin was effective in slowing aging processes, acting as a senolytic agent in multiple organ systems, in an hormetic fashion. In addition, fisetin was broadly neuroprotective, including during fetal development, and preventing the toxicity of methylmercury. Since these findings indicate that fisetin may have the potential to induce multi-system chemoprotective effects, it indicates the need to better clarify the absorption and bioavailability of fisetin and ways to enhance its efficiency.
