4'-Hydroxyacetophenone

4'-Hydroxyacetophenone (CAS No.: 99-93-4) is a naturally occurring small-molecule phenolic compound commonly isolated from medicinal plants such as Artemisia and Illicium species, recognized for its hepatoprotective, choleretic, antiviral, and anti-inflammatory properties. It modulates biological systems through the regulation of cellular signaling pathways associated with cytoskeletal dynamics, particularly by remodeling actin organization, which contributes to the inhibition of cancer cell adhesion, invasion, and migration. In vitro studies indicate that it suppresses hepatitis B virus particle secretion and inflammatory responses at low micromolar to micromolar concentrations, supporting its relevance in antiviral and immunomodulatory research. Additionally, its broader bioactivity profile includes antifungal effects and roles in plant defense-related metabolic changes, reflecting diverse biological interactions. Owing to these properties, 4'-Hydroxyacetophenone is widely utilized in cell-based assays and exploratory in vivo models to investigate mechanisms underlying inflammation, viral infection, and tumor progression, as well as in early-stage drug discovery efforts targeting cytoskeleton-associated pathways and liver-related disorders, with experimental dosing and exposure conditions varying according to specific study designs.
