Product Description
Dichlorisone acetate is a synthetic corticosteroid used as an anti~inflammatory agent.
Dichlorisone acetate (CAS 79-61-8) is a synthetic glucocorticoid corticosteroid with potent anti-inflammatory activity. With the molecular formula C₂₃H₂₈Cl₂O₅ and a molecular weight of 455.37 g/mol, it is a pregnane-class steroid distinguished by its 9α,11β-dichloro substitution pattern. It is primarily used as a topical anti-inflammatory agent for treating various inflammatory and allergic skin conditions.
Biological Activity I Assay Protocols (From Reference)
Targets
Dichlorisone acetate functions as a glucocorticoid receptor (GR) agonist. It diffuses across cell membranes and binds to the cytosolic GR. The ligand-receptor complex then translocates to the nucleus, where it modulates gene transcription, leading to the suppression of pro-inflammatory mediators and the induction of anti-inflammatory proteins. It also exhibits binding affinity for the mineralocorticoid receptor (NR3C2) and other receptors.
ln Vitro
Dichlorisone acetate exerts its primary effect as a potent anti-inflammatory agent in vitro. Its activity is linked to its interaction with the glucocorticoid receptor and downstream signaling pathways. It has also demonstrated antiviral activity, showing inhibition of SARS-CoV-2-induced cytotoxicity in Caco-2 cells at 10 µM. Its specific IC₅₀ for various targets is available in bioactivity databases.
ln Vivo
In vivo, dichlorisone acetate is used for its anti-inflammatory properties. It is applied topically to treat inflammatory and allergic conditions. Its activity is mediated through the glucocorticoid receptor. The compound has also been studied for its effects on metabolic disorders and has been used as an internal standard in analytical methods for quantifying glucocorticoids in equine plasma.
Enzyme Assay
In vitro receptor binding assays are used to characterize its affinity for the glucocorticoid receptor and other nuclear receptors. These assays typically involve competitive binding studies using radiolabeled ligands and membrane preparations from cells expressing the target receptor. Functional assays measure GR-mediated transcriptional activity using reporter genes in cell lines.
Cell Assay
Dichlorisone acetate is used in cell culture to study glucocorticoid signaling. It is typically applied to cells at micromolar concentrations. Its anti-inflammatory effects are assessed by measuring the production of inflammatory cytokines and other mediators. Its antiviral activity has been evaluated in Caco-2 cells.
Animal Protocol
In vivo animal studies for dichlorisone acetate are not extensively documented in the provided literature. It has been used in research related to alopecia and as a standard in analytical studies. Toxicological studies have been conducted to assess its safety profile.
ADME/Pharmacokinetics
Published pharmacokinetic data for dichlorisone acetate is limited. The compound has a molecular weight of 455.37 g/mol and is soluble in DMSO. It is a synthetic corticosteroid, and its pharmacokinetic properties are expected to be similar to other topical glucocorticoids, with absorption through the skin and metabolism in the liver.
Toxicity/Toxicokinetics
The toxicological profile of dichlorisone acetate is characteristic of topical corticosteroids. Common local side effects include burning, stinging, and dryness. Prolonged use can lead to systemic absorption and adrenal suppression. The compound is considered a hazardous substance and should be handled with appropriate safety precautions.
Additional Infomation
Dichlorisone is a corticosteroid hormone.
Dichlorisone acetate is a synthetic glucocorticoid corticosteroid used as an anti-inflammatory agent. It is also known as Diloderm and Dermocid. It is not approved for systemic use in humans and is primarily a research tool for studying glucocorticoid receptor signaling and inflammation.
