What is the Origin of Sirtuin Modulators?

The term and the underlying research originated with the discovery of sirtuins (SIRT1-SIRT7), which are homologs of the yeast Sir2 protein, a factor linked to transcriptional silencing and lifespan extension. The identification of natural compounds, such as resveratrol, as sirtuin activators propelled the concept of "modulators" into the health and wellness lexicon. This area of study is a key pillar of contemporary aging research and metabolic science.

What is the Mechanism of Sirtuin Modulators?

Sirtuin modulators function by binding to the sirtuin enzyme, either directly activating or inhibiting its deacetylase activity, which is dependent on the cofactor Nicotinamide Adenine Dinucleotide (NAD+). Activation of Sirtuin 1 (SIRT1), for example, deacetylates and thereby modulates the activity of numerous transcription factors involved in fat mobilization, glucose metabolism, and cellular stress response. This modulation promotes cellular resilience and can influence the sensitivity of peripheral tissues to endocrine signals.

Sirtuin Modulators

Meaning

Sirtuin Modulators are a class of compounds, either natural or synthetic, that can influence the activity of sirtuins, a family of NAD+-dependent protein deacetylases central to cellular metabolism, DNA repair, and stress resistance. These modulators are of significant interest in the longevity and hormonal health domains because sirtuin activity is intrinsically linked to mitochondrial function and the regulation of key metabolic hormones like insulin. Activating sirtuins is hypothesized to mimic the beneficial effects of caloric restriction.
