5-Acetylsalicylic acid

5-Acetylsalicylic acid (CAS No.: 13110-96-8) is a salicylate related to aspirin and is broadly categorized as a small molecule anti inflammatory research compound for life sciences applications, with particular relevance to inflammation biology, intestinal immunology, and microbiota associated xenobiotic metabolism studies; current evidence describes it as an active metabolite generated in gut associated biotransformation contexts and functionally linked to nonsteroidal anti inflammatory pharmacology, making it suitable for mechanistic investigation in preclinical discovery workflows focused on inflammatory bowel disease biology and mucosal immune regulation. At the molecular level, direct target level selectivity data for this specific compound remain limited, and therefore mechanism oriented interpretation is generally framed through salicylate class effects, including modulation of prostaglandin associated inflammatory signaling and related cytokine regulatory networks, while experimental observations indicate mild cytotoxic activity in B16F10 cells and support its use as a probe to examine inflammatory phenotypes rather than as a highly potent broad spectrum cytotoxin. Quantitative potency constants such as validated IC50 or EC50 values are not consistently established for this molecule in the available dataset, so reported activity is best considered to fall within context dependent pharmacology that is often evaluated across micromolar concentration windows in cell based assays, with study specific optimization required for readouts such as inflammatory mediator production, epithelial barrier response, immune cell activation states, and microbiome influenced metabolic conversion. In translationally oriented nonclinical research, it is commonly positioned for use in in vitro intestinal or immune cell models, inflammation linked co culture systems, and in vivo animal models of colitis or related gut inflammation paradigms, where the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
