Mechanism of Action

Targets/IC₅₀/Ki	SIRT1 (Cell-free assay) 0.16 μM(EC50)
In vitro	The maximum activation ratio of SRT1720 versus the closest sirtuin homologues, SIRT2 (EC1.5 = 37 μM) and SIRT3 (EC1.5 > 300 μM) is up to 781%. SRT1720 binds to the SIRT1 enzyme-peptide substrate complex at an allosteric site amino-terminal to the catalytic domain and lower the Michaelis constant for acetylated substrates. SRT1720 could reduce fed glucose levels. SRT1720 does not have an effect on fasting glucose in chow-fed mice, revealing that pharmacological SIRT1 activation is unlikely to induce hypoglycaemia. SRT1720 significantly reduces the hyperinsulinaemia after 4 weeks, partially normalizing increased insulin levels. SRT1720 treatment increases mitochondrial capacity by 15% in gastrocnemius muscle as measured by citrate synthase activity. Higher concentrations of SRT1720 (15 μM) induces a modest (10-20%) decrease in normal cell viability. SRT1720 also significantly inhibits VEGF-dependent MM cell migration.
Kinase Assay	SIRT1 fluorescence polarization assay
Kinase Assay	In the SIRT1 FP assay, SIRT1 activity is monitored using a 20 amino acid peptide (Ac-Glu-Glu-Lys(biotin)-Gly-Gln-Ser-Thr-Ser-Ser-His-Ser-Lys(Ac)-Nle-Ser-Thr-Glu-Gly–Lys(MR121 or Tamra)-Glu-Glu-NH₂) derived from the sequence of p53. The peptide is N-terminally linked to biotin and C-terminally modified with a fluorescent tag. The reaction for monitoring enzyme activity is a coupled enzyme assay where the first reaction is the deacetylation reaction catalyzed by SIRT1 and the second reaction is cleavage by trypsin at the newly exposed lysine residue. The reaction is stopped and streptavidin is added in order to accentuate the mass differences between substrate and product. The sensitivity of the FP assay allows identification of SRT1720. The fluorescence polarization reaction conditions are as follows: 0.5 μM peptide substrate, 150 μM βNAD⁺, 0-10 nM SIRT1, 25 mM Tris-acetate pH 8, 137 mM Na-Ac, 2.7 mM K-Ac, 1 mM Mg-Ac, 0.05% Tween-20, 0.1% Pluronic F127, 10 mM CaCl 2, 5 mM DTT, 0.025% BSA, and 0.15 mM nicotinamide. The reaction is incubated at 37 °C and stopped by addition of nicotinamide, and trypsin is added to cleave the deacetylated substrate. This reaction is incubated at 37 °C in the presence of 1 μM streptavidin. Fluorescent polarization is determined at excitation (650 nm) and emission (680 nm) wavelengths.
In vivo	In DIO mice SRT1720 mimics several of the effects observed after calorie restriction including improved insulin sensitivity, normalized glucose and insulin levels, and increased mitochondrial capacity. In addition, in diet-induced obese and genetically obese mice, SRT1720 improves insulin sensitivity, lower plasma glucose, and increase mitochondrial capacity. Thus, SRT1720 is a promising new therapeutic agent for treating diseases of ageing such as type 2 diabetes. Consistent with improved glucose tolerance, the glucose infusion rate required to maintain euglycaemia is approximately 35% higher in SRT1720-treated fa/fa rats, and the total glucose disposal rate is increased by approximately 20%. SRT1720 also prevents multiple myeloma tumor growth.

Frequently Asked Questions

Question 1:
How can we prepare it for in vivo mouse studies?

Answer:
It can be dissolved in 30% PEG 400+0.5% Tween 80+5% Propylene glycol at 30mg/ml as a suspension, which is fine for oral gavage. We’ve also found that it can be dissolved in 2% DMSO+30% PEG 300+1% Tween 80+ddH2O at 3mg/ml clearly, making it suitable for injection. When preparing the solution, please dissolve the compound in DMSO clearly first, then add PEG and Tween. After they are mixed well, dilute with water.
