%HA: Percentage of hydrophobic amino acids, GRAVY: Hydrophobicity. a Evaluated by prediction through the use of the online computer tool APD3: Antimicrobial Peptide Calculator and Predictor (http://aps.unmc.edu/AP/). b Chromatographic purity measured by area percentage. AcOx: Oxolinic acid, Fc: ferrocen motif, Glc(Ac4): Tetra acetylated Glucose, Ahx: 6-aminohexanoic residue, AcFer: Ferulic acid.
