Hydrogel membranes are often used as physical barriers in oral tissue reconstruction and facial surgery to isolate connective and epithelial tissues and form a closed space for undisturbed bone healing. In this study, gelatin and hyaluronic acid were crosslinked with genipin and loaded with a hinokitiol additive as a bacteriostatic agent for potential applications as regeneration membranes. This bifunctional membrane had biocompatibility and antibacterial activities on each membrane side for proper biodegradation. Different membrane groups of gelatin/hyaluronic acid were obtained via a solution casting technique and were genipin crosslinked. The membrane groups were further loaded with adequate hinokitiol at a loading concentration of up to 0.16 g/L (hinokitiol to phosphate buffered saline). Fourier transform infrared spectroscopy showed that gelatin and hyaluronic acid were crosslinked with genipin through cross-linking amide bond (CONH) formation with a cross-linking degree of over 84%. The groups with hinokitiol showed substantial antibacterial activity. Meanwhile, the addition of hinokitiol on hydrogel membranes did not significantly affect the tensile strength. However, it decreased the solubility of the membranes by slowing down the relaxation and degradation of their molecular junctions as hinokitiol is a hydrophobic compound with low permeability. Consequently, the degradation of hydrogel membranes with hinokitiol was delayed. In vitro cytocompatibility indicated that the cell viability of the groups with hinokitiol increased with incubation time, demonstrating that cell viability and proliferation were not affected by cell culture testing.

Hinokitiol, a natural lipophilic chelator, appears capable of replacing several iron transporters after they have been genetically ablated. Divalent metal-ion transporter (DMT1) is the major iron importer in enterocytes and erythroblasts. We have compared DMT1 and hinokitiol in multiple fashions to learn if the smaller molecule is a suitable substitute using two HEK293 cell lines engineered to overexpress different isoforms of DMT1. Both the macromolecule and the lipophilic chelator enable import of ferrous ions into HEK293 cells. Hinokitiol also mediates ferric ion import but DMT1 cannot do so. While DMT1 can also import Mn2+ ions, hinokitiol lacks this ability. The Michaelis-Menten analysis for kinetics of macromolecular catalysis is also suitable for hinokitiol-supported iron import. To compare hinokitiol to DMT1 relative to other metal ions that DMT1 can transport, we employed an organic extraction procedure with which we initially matched the results obtained for Fe2+, Fe3+ and Mn2+, and then showed that multiple other cations were unlikely to enter via hinokitiol. The small chelator thus shares some functional properties with DMT1, but distinct difference were also noted.

Hinokitiol, a component of the essential oil isolated from Cupressaceae, possesses antibacterial and antifungal activities and has been used in oral care products. In this study, the antibacterial activities of hinokitiol toward various oral, nasal and nasopharyngeal pathogenic bacteria, including Streptococcus mutans, Streptococcus sobrinus, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Fusobacterium nucleatum, methicillin-resistant and -susceptible Staphylococcus aureus, antibiotic-resistant and -susceptible Streptococcus pneumoniae, and Streptococcus pyogenes were examined. Growth of all these bacterial strains was significantly inhibited by hinokitiol, minimal inhibitory concentrations of hinokitiol against S. mutans, S. sobrinus, P. gingivalis, P. intermedia, A. actinomycetemcomitans, F. nucleatum, methicillin-resistant S. aureus, methicillin-susceptible S. aureus, antibiotic-resistant S. pneumoniae isolates, antibiotic-susceptible S. pneumoniae, and S. pyogenes being 0.3, 1.0, 1.0, 30, 0.5, 50, 50, 30, 0.3-1.0, 0.5, and 0.3 μg/mL, respectively. Additionally, with the exception of P. gingivalis, hinokitiol exerted bactericidal effects against all bacterial strains 1 hr after exposure. Hinokitiol did not display any significant cytotoxicity toward the human gingival epithelial cell line Ca9-22, pharyngeal epithelial cell line Detroit 562, human umbilical vein endothelial cells, or human gingival fibroblasts, with the exception of treatment with 500 μg/mL hinokitiol, which decreased numbers of viable Ca9-22 cells and gingival fibroblasts by 13% and 12%, respectively. These results suggest that hinokitiol exhibits antibacterial activity against a broad spectrum of pathogenic bacteria and has low cytotoxicity towards human epithelial cells.
