All the chemical reactivity descriptors for the systems were calculated via Conceptual Density Functional Theory (CDFT). The potential bioavailability and druggability as well as the bioactivity scoresfor CCK-8 were predicted through different methodologies already reported in the literature which have been previously validated during the study of different peptidic systems. The conclusion was that the CCK-8 peptide will be moderately bioactive regarding all the interactions. %K Cholecystokinin Peptide Hormone (CCK-8) %K Conceptual DFT %K Chemical Reactivity %K Drug-likeness Features %K Bioactivity Scores %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=93348
