Preparing and immobilizing antimicrobial osteogenic growth peptide on titanium substrate surface.

The inherent bioinertness and potential bacterial infection risk are the two leading causes for Ti implant failure. To improve osseointegration and antibiosis, in this work, a novel antimicrobial osteogenic growth peptide was first synthesized by conjugating osteogenic growth peptide (OGP) and ciprofloxacin (CIP). Then, the synthetic antimicrobial peptide was immobilized onto Ti implant surface for chemoselective binding via the amide reaction. Thereafter, the capabilities of modified Ti implant on osseointegration and antibiosis were measured with cell experiments and antimicrobial activity in vitro. The results showed that antimicrobial osteogenic growth peptide (OGP-CIP) was successfully prepared and grafted onto Ti implant surface. Moreover, the antimicrobial peptide-modified Ti implants could promote osteoblasts spreading and osteodifferentiation compared with unmodified Ti substrates. Meanwhile, in vitro bacteria studies (Staphylococcus aureus and Escherichia coli) proved that the antibacterial property of antimicrobial peptide functionalized Ti implant was improved obviously. The method used in this work is a feasible and promising strategy to win the race against invading bacteria and accelerate bone integration in orthopedic implantation. © 2018 Wiley Periodicals, Inc.
