Fluorometholone

Fluorometholone (CAS No.: 426-13-1) is a synthetic glucocorticoid widely utilized in biomedical research as a potent agonist of the glucocorticoid receptor, exhibiting pronounced anti-inflammatory and anti-allergic activities. By binding to intracellular glucocorticoid receptors with high affinity in the nanomolar range, it modulates gene transcription pathways involved in immune suppression, cytokine regulation, and inhibition of inflammatory mediator production, including effects on NF-κB and related signaling cascades. Fluorometholone is commonly applied in studies of ocular inflammation and dry eye disease, as well as broader investigations into steroid-responsive pathways, where it serves as a model compound for glucocorticoid pharmacology. In vitro, it has been shown to influence corneal epithelial cell viability and migration, supporting its relevance in epithelial biology and wound-healing assays. Its established use in ophthalmic and topical formulations further underpins its utility in translational research models examining inflammatory disorders of the eye and skin. Experimental applications typically employ concentration ranges tailored to specific assay systems, enabling its use in mechanistic studies, target validation, and anti-inflammatory drug screening.
