Biological Activity

Targets	NF-κB 1.58 μM (EC50)
ln Vitro	In SH-SY5Y neuroblastoma cells, NF-κΒ activator 2 (compound 61) (1 μM, 6 h) stimulates SOD2 mRNA expression[1].
ln Vivo	In mice, NF-κB activator 2 (1 mg/kg; iv) has an appropriate half-life of 0.96 hours[1]. Comparable half-lives (2.86 hours), oral bioavailability (15.6%), and Cmaxes (92 ng/mL) are shown by NF-κΒ activator 2 (5 mg/kg; po)[1].

Solubility Data

Solubility (In Vitro)

DMSO :~250 mg/mL (~838.17 mM)

Solubility (In Vivo)

Solubility in Formulation 1: ≥ 2.08 mg/mL (6.97 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 20.8 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	3.3527 mL	16.7633 mL	33.5267 mL
	5 mM	0.6705 mL	3.3527 mL	6.7053 mL
	10 mM	0.3353 mL	1.6763 mL	3.3527 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.
