Partial molar volumes of the drugs Parvon Spas, Parvon Forte, Tramacip, and Parvodex in aqueous mixtures of methanol (MeOH), ethanol (EtOH), and propan-1-ol (1-PrOH) have been determined. The data have been evaluated using the Masson equation. The parameters, apparent molar volumes (φ v ), partial molar volumes (φ 0 v ), and S v values (experimental slopes) have been interpreted in terms of solute-solvent interactions. In addition, these studies have also been extended to determine the effect of these drugs on the solvation behavior of an electrolyte (sodium chloride), a surfactant (sodium dodecyl sulfate), and a non-electrolyte (sucrose). It can be inferred from these studies that all drug cations can be regarded as structure makers/promoters due to hydrophobic hydration. Furthermore, the results are correlated to understand the solution behavior of drugs in aqueous-alcoholic systems, as a function of the nature of the alcohol and solutes.

“…The changes in the absorption spectrum of solutes associated with the presence of micellar aggregates allow the discrimination between molecules in the different solubilization environments enabling the quantification of free or micelle-bound solute, whenever solute micellar binding/incorporation is accompanied by appropriate spectral shifts [14,27]. Sodium dodecyl sulfate critical micelle concentration (CMC) in the presence of MeOH (3%), and Tris buffer was determined through surface tension measurements, using a titrimetric procedure, and resorting to Gibbs equation (CMC ¼ 1.23 Â 10 À3 M) [32,36,[39][40][41]. The partition toward a micellar pseudo phase is described by a saturation curve, therefore, if the CMC is known, K p (K p ¼ x sulf,mic /x sulf,w ) where x sulf,w and x sulf,mic are equilibrium sulfenamide mole fractions in aqueous and micellar media) can be determined.…”

Several sulfenamide derivatives were designed as possible acetylcholinesterase (AChE) inhibitors. New sulfenamides were synthesized and proved to be stable under the physiological conditions used in the enzymatic assays. N‐benzyl‐2‐benzoxazolylsulfenamide (8) and N‐benzyl‐2‐benzimidazolylsulfenamide (9) revealed anti‐AChE activity with IC50 values of 0.6 and 0.8 μM, respectively, values of the same magnitude as those reported for galantamine and tacrine. The affinity for the biological site was evaluated in terms of interaction/partition toward sodium dodecyl sulfate (SDS) micelles. The inhibitory activity profiles were reasoned in terms of both partition toward a hydrophobic anionic environment and molecular geometry. The XCSN dihedral angle deviations from collinearity stood out as a major parameter linked to enzyme specificity. J. Heterocyclic Chem., (2011).
