Fosfosal

Fosfosal (CAS No.: 6064-83-1) is a synthetic small molecule classified as a non acetylated salicylic acid derivative and phosphonooxy substituted aromatic acid that is primarily positioned in inflammation biology and pain related pharmacology research as a tool compound for mechanistic studies rather than clinical translation, with reported anti inflammatory and analgesic like bioactivity and additional antibacterial observations in experimental systems; current evidence indicates that its mechanism is associated with modulation of inflammatory mediator networks through salicylate related biology while showing limited direct suppression of prostaglandin biosynthesis in vitro, so it is commonly investigated as a comparator for cyclooxygenase dependent versus cyclooxygenase independent signaling, including effects linked to cellular stress response pathways and transcriptional regulation of inflammatory genes, although definitive single protein target assignment remains incomplete in publicly summarized datasets; consistent with this profile, published research descriptions generally report activity across nanomolar to micromolar to low millimolar exposure windows depending on assay format and biological endpoint, and antibacterial effects are typically discussed qualitatively or in broad micromolar relevant ranges when strain and medium conditions vary; in biomedical discovery workflows it is used in cell based inflammation models, microbial susceptibility assays, and selected animal pharmacology paradigms to benchmark pathway selective anti inflammatory phenotypes, examine structure activity relationships within salicylate analog series, and support early stage screening cascades focused on inflammatory signaling modulation and host response biology, and the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
