MDL-800 (MDL800) is a first-in-class, selective, cellular active SIRT6 allosteric activator, increases SIRT6 deacetylation activity with EC50 of 10.3 uM in RHKK-ac-AMC and FDL assays; dramatically enhanced SIRT6 deacetylation activity by more than 22-fold, displays no activity toward SIRT1, SIRT3, SIRT4, and HDAC1-11 at 50-100 uM, as well as >10-fold selectivity toward SIRT2, SIRT5, and SIRT7; activates SIRT6 through a surface allosteric site induces H3K9ac and H3K56ac deacetylation and represses proliferation of HCC cells (IC50=23.3 uM); inhibits xenograft tumor growth of HCC cells in immunocompromised mice by activating the deacetylase activity of SIRT6.




SirReal2 (MZ25) is a novel potent, selective Sirt2 inhibitor with IC50 of 0.435 uM; displays >1,000-fold more potently than Sirt1, Sirt3, Sirt4, Sirt5 and Sirt6; increases α-tubulin acetylation in HeLa cells, significantly results in a dose-dependent depletion of BubR1.



JH-T4 is a potent small molecule SIRT2 inhibitor with IC50 of 0.3 uM (sirtuin deacylation activity), increase intracellular K-Ras4a lysine fatty acylation; inhibited both the deacetylation and defatty-acylation activity of SIRT2 in vitro with IC50 of 30-50 nM; JH-T4 is the first small molecule inhibitor that can modulate the lysine fatty acylation levels of K-Ras4a. JH-T4 also inhibits SIRT1 and SIRT3 in vitro.

SirT1 enhancer A03

66171-75-3 SirT1 enhancer A03 is a specific, orally bioavailable, brain penetrant apolipoprotein E4 (ApoE4)-targeted sirtuin1 (SirT1) enhancer, increases the levels of the neuroprotective enzyme SirT1 while not affecting levels of neurotoxic SirT2 in vitro in ApoE4-transfected cells (EC50=2 uM); increases SirT1 levels in the hippocampus of Alzheimer's disease (AD) model mice and elicits cognitive improvement while inducing no observed toxicity


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.


1031195-19-3 E1231 (E-1231) is a small molecule SIRT1 activator with EC50 of 0.83 uM, interactes with recombinant human SIRT1 protein and deacetylated liver X receptor-alpha (LXRα); increases ATP-binding cassette transporter A1 (ABCA1) expression in RAW 264.7 cells dependent on SIRT1 and LXRα, promotes cholesterol efflux and inhibited lipid accumulation in RAW 264.7 cells via SIRT1 and ABCA1; decreases total cholesterol and triglyceride levels in both serum and the liver in golden hamster hyperlipidemia models.


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.
