Salermide is a potent inhibitor of Sirt1/2 (Sirtuin 1/2) with a strong cancer-specific proapoptotic effect mediated by Sirt1. Class III histone deacetylases that are dependent on NAD+ (nicotinamide adenine dinucleotide-positive) include Sirt1 and Sirt2, which are involved in lifespan regulation. Since cancer is an age-related illness, focusing on sirtuins is becoming more and more popular as an antitumor tactic. Salermide is a reverse amide that significantly inhibits Sirt1 and Sirt2 in vitro. Salermide caused tumor-specific cell death in a variety of human cancer cell lines and was well tolerated by mice at concentrations up to 100 muM. Salermide's antitumor activity was mostly brought on by a significant induction of apoptosis. This suggested an in vivo mechanism of action via Sirt1 and was independent of global tubulin and K16H4 acetylation, ruling out a potential Sirt2-mediated apoptotic pathway. This is supported by the fact that cancer cells underwent apoptosis when Sirt1 but not Sirt2 was knocked down via RNA interference. Genetic p53 knockdowns demonstrated that Salermide's Sirt1-dependent proapoptotic effect is p53-independent, despite reports that p53 is a target of Sirt1. When combined, these findings point to the potential of salermide as an anticancer medication and provide light on the molecular pathway by which Sirt1 contributes to human carcinogenesis.

Enzyme Assay |
The deacetylase activity of recombinant His-tagged human Sirt1 and Sirt2 was measured using the HDAC fluorescent activity assay (BIOMOL, Plymouth, PA, USA). The reactions lasted 60 minutes at 37 °C. The mean and standard deviation of four separate experiments are used to express the results.

|
Cell Assay |
Cell lines (SW480, MDA-MB-231, MOLT4, KG1A, K562 and Raji) are used in the study. Cell viability is determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. IC50 index is calculated using four Salermide concentrations (25, 50, 75 and 100 μM) for 24 h. The percentage of apoptotic cells is determined with the FACSCalibur apparatus[1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.34 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
1 mM | 2.5350 mL | 12.6752 mL | 25.3505 mL | |
5 mM | 0.5070 mL | 2.5350 mL | 5.0701 mL | |
10 mM | 0.2535 mL | 1.2675 mL | 2.5350 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
