Diclofensine HCl salt (also known as Ro-8-4650 HCl) is a novel and potent inhibitor of monoamine reuptake which blocks the uptake of dopamine, noradrenaline, and serotonin by rat brain synaptosomes with IC50 values of 0.74, 2.3, and 3.7 nM, respectively. Diclofensine is used as an antidepressant with equipotent inhibitive effects on the neuronal uptake of norepinephrine (NE), serotonin, and dopamine.

Solubility Data

Solubility (In Vitro)

H2O : ≥ 52 mg/mL (~144.97 mM) DMSO : ~6.67 mg/mL (~18.60 mM)

Solubility (In Vivo)

Solubility in Formulation 1: ≥ 0.67 mg/mL (1.87 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 6.7 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	2.7879 mL	13.9396 mL	27.8792 mL
	5 mM	0.5576 mL	2.7879 mL	5.5758 mL
	10 mM	0.2788 mL	1.3940 mL	2.7879 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.
