Hinokitiol

Hinokitiol is a naturally occurring tropolone compound found in the heartwood of several trees, including Japanese cypress. It binds metal ions and has antimicrobial activity.

Metal chelation: The binding of a metal ion by a molecule at two or more sites. Hinokitiol coordinates metal ions through oxygen atoms in its ring.
Toothpaste: A paste or gel used with a toothbrush to clean teeth. Hinokitiol is included in some oral-care products for its antimicrobial properties.
Japanese cypress: A conifer native to Japan, valued for its durable, fragrant timber. Hinokitiol was isolated from the heartwood of Japanese cypress.
Usnic acid: A lichen-derived dibenzofuran compound with antimicrobial activity. Both are natural antimicrobial compounds, but their structures and sources differ.
Iron: A chemical element whose ions are essential cofactors in many biological processes. Hinokitiol can transport iron across membranes, affecting iron availability to cells.
Periodontal disease: Inflammatory conditions affecting the tissues that support the teeth. Hinokitiol has been studied for activity against bacteria associated with periodontal disease.
Taiwan cypress: A conifer native to Taiwan whose heartwood contains aromatic compounds. Hinokitiol also occurs in the heartwood of Taiwan cypress.
Chelator: A substance that binds a metal ion through multiple coordinating atoms. Unlike many chelators used to sequester metals, hinokitiol can facilitate metal transport.
Ionophore: A molecule that facilitates the movement of ions across a biological membrane. Its ability to shuttle metal ions across membranes gives hinokitiol ionophore-like behavior.
Cosmetics: Products applied to the body to cleanse, protect, or alter appearance. Hinokitiol is used in some cosmetic formulations as an antimicrobial ingredient.
