Role of 4-Hexylresorcinol in the Field of Tissue Engineering

Abstract

4-hexylresorcinol (4-HR), as a derivative of phenolic lipids, has biological and pharmacological properties that are beneficial when used with a biomaterial. It has antimicrobial and antiseptic activity and can thus prevent contamination and infection of biomaterials. 4-HR suppresses the nuclear factor kappa B (NF-κB) signaling pathway related to osteoclast differentiation. The suppression of NF-κB increases the bone formation marker and contributes to new bone formation. The tumor necrosis factor-α (TNF-α) is a pro-inflammatory cytokine produced by macrophages and suppressed by 4-HR. Suppression of TNF-α decreases osteoclast activity and promotes wound healing. 4-HR increases the vascular endothelial growth factor and has an anti-thrombotic effect. When incorporated into silk vascular patches, it promotes endothelium wound healing. Recently, 4-HR has exhibited biological properties and has been successfully incorporated into various biomaterials. Consequently, it is a useful pharmacological chemical that can be used with biomaterials in the field of tissue engineering.
