Background:

Chloroxine is one of the important 8-hydroxyquinoline derivative. Chloroxine has effective antibacterial, antifungal, antiprotozoal and antiamoebic activities, especially used in treating the intestinal amebiasis. Chloroxine is also used in the treatment of dandruff and seborrheic dermatitis of the scalp[1][2].

By using the Jouyban-Acree model, the Chloroxine solubility is well correlated obtaining RAD values lower than 3.64% and RMSD values lower than 8.82?×?10?6. Chloroxine is preferentially solvated by water for the studied mixtures in water-rich compositions; while within intermediate and co-solvent-rich compositions, Chloroxine is preferentially solvated by DMSO (DMF, NMP or 1,4-dioxane) in DMSO (DMF, NMP or 1,4-dioxane)?+?water mixtures. It is shown that the change in solvent-solvent interaction energy accounted by cavity term governed the solubility variation of Chloroxine in all aqueous mixtures[1].
