Interaction study of L‑phenylalanine/glycyl‑L‑phenylalanine in water‑soluble 1‑decyl‑3‑methylimidazolium bromide ([C10mim]Br) ionic liquid: thermodynamic/physicochemical approaches

Recent times have witnessed notable progress in augmenting the efectiveness of pharmaceutical actions, leading to the creation of novel drug formulations and delivery technologies. A complete understanding of the molecular-level interactions between drug molecules and biological membranes is necessary to achieve optimal design in these processes. Comprehensive understanding of these interactions can be gained through thermodynamic research, which helps pharmaceutical professionals make well-informed decisions about which manufacturing compounds are most suited for a certain application. Because ionic liquids can interact with biological membranes and exert their efects on them, studying ionic liquids in combination with co-solvents in aqueous settings is important for many kinds of research. Using an Anton Paar DSA 5000 M apparatus, the densities, and speed of sound in a liquid mixture comprising L-phenylalanine and glycyl-L-phenylalanine within an aqueous 1-decyl-3-methylimidazolium bromide ([C10mim]Br), the ionic solution was measured. This was done across temperature ranges of 288.15 K, 298.15 K, 308.15 K, and 318.15 K and experimental pressure of p=0.1 MPa with concentrations of “0.000, 0.005, 0.030, and 0.050 mol kg–1”. From the experimental results, various acoustic and physicochemical properties were derived, including apparent molar properties, partial compression, isentropic compression, and transfer properties. These computations provided insights into intermolecular interactions within the combination of 1-decyl-3-methylimidazolium bromide, water, L-phenylalanine, and glycyl-L-phenylalanine. The mixture’s characteristics were explored through pair and triplet coefcients, taking into account empirical constants and expansibilities, thereby delving into solute–solvent, hydrophilic-hydrophilic, dipole–dipole, and ion-hydrophilic interactions.
