Compound Overview

SIRT-IN-3 is a potent SIRT inhibitor, with an IC50 of 17 μM against SIRT1. It shows roughly 4-fold and 14-fold selectivity for SIRT1 over SIRT2 and SIRT3, respectively, corresponding to IC50 values of 74 μM and 235 μM against SIRT2 and SIRT3[1]. It is supplied as a white to yellow solid (C13H12N2O, MW 212.25) at 98.10% purity.

Safety

For Research Use Only. Not for use in diagnostic or therapeutic procedures, and not for human or veterinary use. Handle in accordance with the Safety Data Sheet and your institution's chemical hygiene plan.

In Vitro

SolventSolubilityNotes
DMSO125 mg/mL (588.93 mM)requires sonication; use freshly opened DMSO (absorbed moisture lowers solubility)

Aliquot the stock solution and store it at -80°C (up to 6 months) or -20°C (up to 1 month); protect from light; avoid repeated freeze-thaw cycles.

In Vivo

Choose the formulation that suits the animal model and route of administration; percentages are volume ratios of the final working solution. Start from a clear DMSO stock (see In Vitro above), add the co-solvents one at a time in the order listed, mixing after each addition, and prepare the working solution fresh on the day of dosing. If precipitation or phase separation occurs, gentle warming or sonication can help.

Protocol 1

Composition10% DMSO + 40% PEG300 + 5% Tween-80 + 45% saline
Result≥ 2.08 mg/mL (9.80 mM); clear solution
How to prepareGives a clear solution at ≥ 2.08 mg/mL (saturation not determined). For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 400 μL PEG300; then 50 μL Tween-80; then 450 μL saline to bring the volume to 1 mL. Saline: dissolve 0.9 g sodium chloride in ddH2O and make up to 100 mL.

Protocol 2

Composition10% DMSO + 90% (20% SBE-β-CD in saline)
Result≥ 2.08 mg/mL (9.80 mM); clear solution
How to prepareGives a clear solution at ≥ 2.08 mg/mL (saturation not determined). For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 900 μL 20% SBE-β-CD in saline. 20% SBE-β-CD in saline: dissolve 2 g SBE-β-CD powder in 10 mL saline until clear (4°C, store up to one week).

Protocol 3

Composition10% DMSO + 90% Corn Oil
Result≥ 2.08 mg/mL (9.80 mM); clear solution
How to prepareGives a clear solution at ≥ 2.08 mg/mL (saturation not determined). Use with caution if continuous dosing will exceed two weeks. For 1 mL of working solution: add 100 μL DMSO stock (20.8 mg/mL) to 900 μL corn oil.
