Outline of Final Research Achievements |
Two functional artificial peptide were synthesized chemically by the fusion with Histatin 5 or Lactoferricin peptide motif, known as antimicrobial peptide, and Zirconia binding peptide motif. These peptides dissolved in solvents were coated on the surface of Zirconia disc, and then, P. gingivalis, well-known as periodontopathic bacterium, was incubated for two days at 37°C under aerobic condition. Subsequently, the activity of these peptides was evaluated with determination of viable bacteria count. The viable bacteria count in theses peptides were reduced gradually in a concentration dependent manner of peptide. From the result, it suggested that two novel functional artificial peptides have antimicrobial activity against a P gingivalis.
