5-Iodotubercidin (also known as NSC 113939, 5-ITu) is a novel and potent adenosine kinase inhibitor with IC50 of 26 nM. It inhibits nucleoside transporter, CK1, insulin receptor tyrosine kinase, phosphorylase kinase, PKA, CK2 and PKC. 5-Iodotubercidin increases fatty acid oxidation activity and glycogen synthesis in hepatocytes. In cultured rat hepatocytes, 5-iodotubercidin inhibits both acetyl-CoA carboxylase and de novo synthesis of fatty acids and cholesterol.
| ln Vitro |
5-Iodotubercidin (NSC 113939) has IC50 values of 0.4, 3.5, 5-10, 5-10, 10.9, and 27.7 μM, respectively, and inhibits CK1, insulin receptor tyrosine kinase, phosphorylase kinase, PKA, CK2, and PKC[1]. 5-A significant drop in ATP concentration and a corresponding, minor increase in AMP concentration are caused by iodotubercidin (20 μM). 5. Iodotubercidin lowers the rates of fatty acid and cholesterol synthesis as well as the activity of ACC. The intracellular concentration of malonyl-CoA is significantly reduced by 5-iodotubercidin, which is consistent with the iodotubercidin-mediated Inhibition of ACC[4].

| ln Vivo |
5-Iodotubercidin (1 mL/kg, ip) has been shown to be effective against bicuculline-induced seizures after AKI was administered locally to the prepiriform cortex[2].

Solubility in Formulation 1: ≥ 2.5 mg/mL (6.38 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.38 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*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.
