Diflucortolone valerate

Diflucortolone valerate (CAS No.: 59198-70-8) is a synthetic small molecule corticosteroid ester and a diflucortolone derivative that is broadly classified within glucocorticoid receptor modulators for inflammation related biology research, and it is commonly used as a reference compound in dermatology oriented pharmacology studies to investigate steroid responsive transcriptional control of immune and barrier associated processes; mechanistically, available class level evidence indicates that this agent primarily engages the glucocorticoid receptor NR3C1 to regulate receptor dependent nuclear signaling, including transrepression of pro inflammatory transcription factor networks such as NF kappa B and AP 1 and transactivation of glucocorticoid responsive genes, thereby providing a robust tool for probing cytokine suppression, leukocyte signaling attenuation, and cellular programs linked to erythema, edema, and pruritus associated pathways in experimental systems; although publicly summarized records for this specific compound are often qualitative rather than fully parameterized, reported activity for potent topical corticosteroid class members is generally observed from nanomolar to low micromolar concentration ranges in cell based assays depending on endpoint selection, receptor context, and exposure duration, and its use in vitro and in vivo is typically framed around comparative efficacy profiling, mechanism focused assays, and anti inflammatory pathway benchmarking in keratinocyte, fibroblast, and immune cell models as well as preclinical skin inflammation paradigms, where the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
