Expert Opinion on Therapeutic Patents, 2009
The sirtuin family of deacetylase enzymes comprises seven proteins (SIRT1-7) that are dependent on NAD(+) for their activity. Three proteins are located in the nucleus, three in the mitochondria and only one is predominantly cytoplasmic. Caloric restriction and oxidative stress generally up-regulate their expression. SIRT1, the orthologue of yeast Sir2,

Sirtuins are involved in numerous biological processes such as cell survival and metabolism, aging, and DNA repair; thus they modulate crucial metabolic pathways. The seven members of the Sirtuin family are more and more seen as potential targets for the treatment of cancer, metabolic, neurodegenerative, and cardiovascular diseases.

Sirtuins have emerged as important proteins in aging, stress resistance and metabolic regulation. Three sirtuins, SIRT3, 4 and 5, are located within the mitochondrial matrix. SIRT3 and SIRT5 are NAD(+)-dependent deacetylases that remove acetyl groups from acetyllysine-modified proteins and yield 2'-O-acetyl-ADP-ribose and nicotinamide.

Sirtuin 1-7 (SIRT1-7) are deacetylases that are dependent on NAD(+) for their activity. SIRT1 down-regulates p53 activity, increasing lifespan, cell survival, and neuroprotection; it also deacetylates peroxisome proliferator-activated receptor-gamma and its coactivator 1alpha, promoting fat mobilization, increasing mitochondrial size and number, and ...

The nematode Caenorhabditis elegans (C. elegans) has four Sir2 paralogs, sir-2.1, sir-2.2, sir-2.3, and sir-2.4. Thus far, most of the research tools to study worm sirtuins have been developed for sir-2.1, due to its homology to yeast SIR2 and human SIRT1.

Flavonoids as Sirtuin Modulators
Current Topics in Medicinal Chemistry, 2022Abstract: Sirtuins (SIRTs) are described as NAD+-dependent deacetylases, also known as class III histone deacetylases. So far, seven sirtuin genes (SIRTS 1–7) have been identified and characterized in mammals and also known to occur in bacteria and eukaryotes.

Sirtuins: Multifaceted Drug Targets
Current Molecular Medicine, 2011Sirtuin (Sir2) proteins being key regulators of numerous cellular processes have been, over the recent past, the subject of intense study. Sirs have been implicated in diverse physiological processes ranging from aging and cancer to neurological dysfunctions.
