| This research reported the equilibrium solubility profile, solvent effect, Hansen solubility parameter, and solvation performance for MBQ-167 dissolved in aqueous mixtures of cosolvents (i.e., ethanol/isopropanol/acetonitrile/n-propanol, 1) using numerous computational methodologies. All experimentations for equilibrium solubility attainment were carried out using a common shake-flask technique at a pressure of p = 101.2 kPa and elevated temperatures (278.15–323.15 K). The obtained solubility data of MBQ-167 were the highest in neat cosolvents (1) at 323.15 K and the lowest in water (2) at 278.15 K. The solubility behavior was studied through the three-dimensional Hansen solubility parameters. The quantitative description of solvent effect was performed via modeling the MBQ-167 solubility by means of linear solvation energy relationships. Acceptable correlation results for solubility data were achieved through numerous mathematical models corresponding to modified van’t Hoff–Jouyban–Acree, mixture response surface, modified Wilson, Jouyban–Acree, and Apelblat with relative average errors of less than 6.22%. In addition, the solubility magnitude at 298.15 K was investigated via the extended Hildebrand solubility approach, which described the observed solubility data to within a RAD of <2.12%. A quantitative analysis of preferential solvation of MBQ-167 was made using the tool of inverse Kirkwood–Buff integrals. The preferential solvation parameters are positive in solutions with cosolvent-rich and middle compositions, indicating preferential solvation of the drug MBQ-167 by the cosolvent. MBQ-167 perhaps performs as a Lewis acid with isopropanol/ethanol/n-propanol molecules in the composition ranges, while for the acetonitrile solution, the solvation is contributed by the polarization effect. |
