Request The Product List ofSirtuin Sirtuin

Sirtuin (Sir2 proteins) are a class of proteins that possess either mono-ADP-ribosyltransferase, or deacylase activity, including deacetylase, desuccinylase, demalonylase, demyristoylase and depalmitoylase activity. Sirtuins regulate important biological pathways in bacteria, archaeaand eukaryotes. Sirtuins have been implicated in influencing a wide range of cellular processes like aging, transcription, apoptosis, inflammation and stress resistance, as well as energy efficiency and alertness during low-calorie situations. Sirtuins can also control circadian clocks and mitochondrial biogenesis.

Inaxaplin

2446816-88-0

Inaxaplin is a potent apolipoprotein L1 (APOL1) function inhibitor with IC50 of < 0.25μM toward thallium assay and trypanosoma assay.

H9142

Nicotinamide riboside Chloride

23111-00-4

Nicotinamide riboside Chloride is an orally active NAD+ precursor, increases NAD+ levels and activates SIRT1 and SIRT3. Nicotinamide riboside is a source of vitamin B3 (niacin) and enhances oxidative metabolism, protection against high fat diet-induced metabolic abnormalities. Nicotinamide riboside reduces cognitive deterioration in a transgenic mouse model of Alzheimer’s disease.

Nicotinamide riboside

1341-23-7

Nicotinamide riboside is an orally active NAD+ precursor, increases NAD+ levels and activates SIRT1 and SIRT3. Nicotinamide riboside is a source of vitamin B3 (niacin) and enhances oxidative metabolism, protection against high fat diet-induced metabolic abnormalities. Nicotinamide riboside reduces cognitive deterioration in a transgenic mouse model of Alzheimer’s disease.

Dalosirvat

1360540-81-3

Dalosirvat a potent small molecule sirtuin (SIRT) activator.

H2843

YK-3-237

1215281-19-8

A novel small molecule sirtuin-1 (SIRT1) activator that reduces acetylation of mutant 53 and exhibits anti-proliferative effects against TNBC cells carrying mutant p53; demonstrates proliferation inhibition in breast cancer cell panel with EC50 of 0.1-5 uM, also induces PARP-dependent apoptotic cell death and arrests the cell cycle at G2/M phase; enhances expression of α-SMA and fibronectin in cultured rat renal interstitial fibroblasts (NRK-49F).

H2842

UBCS039

358721-70-7

UBCS039 (UBCS-039) is the first synthetic activator of the NAD+-dependent protein lysine deacetylase SIRT6 with EC50 of 38 uM; shows robust activating effects on Sirt6-dependent H3K18ac deacetylation of full-length histone proteins and complete HeLa nucleosomes, with no statistically significant effects on basal Sirt1, 2, and 3 deacetylation activities; induces autophagosome accumulation and promotes autophagic flux in human cancer cells, triggers ROS accumulation and activates the AMPK/ULK1 signaling pathway.

H2841

Thiomyristoyl

1429749-41-6

Thiomyristoyl is a highly selective and potent SIRT2 inhibitor with IC50 of 28 nM, displays no significant activity against SIRT1/3/5/6/7 (Ic50>100 uM); promotes c-Myc ubiquitination and degradation, exhibits broad anticancer effect in various human cancer cells while having limited effects on non-cancerous cells; demonstrates in vivo effect in mouse models of breast cancer.

H2840

Tenovin-D3

1258283-70-3

A novel selective, small-molecule inhibitor of sirtuin SITR2 with IC50 of 21.8 uM; shows much weaker actvity for SIRT1 (IC50>90 uM), SIRT3 and HDAC8; promotes expression of the cell-cycle regulator and p53 target p21(WAF1/CIP1) (CDKN1A) in a p53-independent manner, fails to increase p53 levels or transcription factor activity.

H2839

Tenovin-1

380315-80-0

Tenovin-1 (Tenovin1) is a small molecules that activate p53 and decreases tumor growth through inhibition of the protein-deacetylating activities of SirT1 and SirT2; causes significantly greater growth inhibition, cell death via apoptosis, as well as superior p53 promoter upregulation in wtp53 MyLa cells when combined with vorinostat; elicits caspase-mediated cell death in p53 wild-type cells, but caspase-independent cell death in p53 null cells.

H2838

SRTCX1003

1203480-93-6

SRTCX1003 (SRTCX-1003) is a small molecule activator of SIRT1 (STAC) with EC1.5 of 0.61 uM, enhances deacetylation of cellular p65 protein with IC50 of 1.42 uM in cellular p65 acetylation assay; suppresses TNFα-induced NF-κB transcriptional activation and reduction of LPS-stimulated TNFα secretion in a SIRT1-dependent manner, decreases the production of the proinflammatory cytokines TNFα and IL-12 in acute mouse model of LPS-induced inflammation.
