Abstract:
The study highlights the balance of the intermolecular forces governing the interaction between drugs and mucin. The interaction strength is expressed as a retention factor k (data retrieved from the literature (Gargano et al., 2014)) obtained by a new bio-affinity chromatographic method in which the stationary phase is based on covalently immobilized mucin (porcine gastric mucin, PGM). A quantitative structure-property relationship (QSPR) between logk and 82 VolSurf+ descriptors was established and mechanistically interpreted. Results evidence that all blocks contribute similarly to the model; moreover, hydrogen bonding donor (HBD) properties of solutes favor the interaction with mucin; and thus, support their detrimental role on drug permeability.

Intermolecular Forces in Solutions
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...
