| Targets |
Methyl 13-cis-4-oxoretinoate acts as a retinoic acid receptor (RAR) agonist. By binding to and activating RARs, it modulates gene expression involved in cell differentiation, proliferation, and apoptosis. Its activity as a retinoid metabolite suggests it may play a role in the biological effects of retinoids in neuroblastoma and other tissues. The compound is related to 13-cis-retinoic acid (isotretinoin), a well-known retinoid used in dermatology and oncology, and its 4-oxo metabolite is an important intermediate in retinoid metabolism.

|---|---|
| ln Vitro |
In vitro, methyl 13-cis-4-oxoretinoate activates retinoic acid receptors (RARs) in cell-based reporter assays. It has been studied in neuroblastoma cells as a retinoid metabolite. Its activity is characterized by concentration-dependent RAR activation, induction of differentiation markers, and inhibition of cell proliferation in various cell lines. As a retinoid, it likely exhibits similar in vitro activities to other RAR agonists, including induction of differentiation in leukemia and neuroblastoma cells and modulation of keratinocyte differentiation.
|
| ln Vivo |
In vivo, methyl 13-cis-4-oxoretinoate is promising for research in dermatological diseases and cancers. As a retinoid, it may exhibit similar in vivo effects to other retinoids, including induction of differentiation, inhibition of tumor growth, and modulation of immune responses. However, detailed in vivo studies specifically on this compound are limited. Its identification as a metabolite in neuroblastoma suggests it may contribute to the biological activity of retinoids in this tumor type.

| Enzyme Assay |
In vitro enzyme/receptor binding studies for methyl 13-cis-4-oxoretinoate typically involve radioligand binding assays using recombinant retinoic acid receptors (RARα, RARβ, RARγ) or RXR receptors. Competitive binding experiments with labeled retinoic acid are performed to determine binding affinity (Ki) at the different receptor subtypes. Transactivation assays in cells transfected with RAR or RXR expression vectors and reporter genes are used to measure agonist activity. Standard protocols involve incubating cells with increasing concentrations of the compound and measuring luciferase or other reporter activity.
|
| Cell Assay |
In vitro cellular assays for methyl 13-cis-4-oxoretinoate include studies using neuroblastoma cell lines, keratinocytes, or other retinoid-responsive cells. Cells are treated with serial dilutions of the compound, and differentiation is assessed by morphological changes and expression of differentiation markers (e.g., cytokeratins in keratinocytes, neuronal markers in neuroblastoma). Proliferation is measured by [3H]-thymidine incorporation or cell counting. Apoptosis is quantified by flow cytometry with Annexin V/PI staining. Reporter assays using RAR-responsive luciferase constructs are also employed.
|
| Animal Protocol |
In vivo animal studies for methyl 13-cis-4-oxoretinoate would typically involve mouse models of cancer (e.g., neuroblastoma xenografts) or dermatological diseases (e.g., psoriasis-like skin inflammation). Animals are treated with the compound via oral or intraperitoneal administration, and tumor growth, skin differentiation, or inflammation is assessed. However, specific published in vivo studies for this particular compound are limited. Related retinoids have well-established in vivo efficacy, and this compound is expected to show similar activity in relevant models.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties of methyl 13-cis-4-oxoretinoate are expected to be similar to other retinoid esters, with good oral absorption and extensive metabolism. As a methyl ester, it may be hydrolyzed to the active acid form (13-cis-4-oxoretinoic acid) in vivo. Retinoids are highly protein-bound, distribute widely in tissues, and are metabolized in the liver via cytochrome P450 enzymes. The compound has a molecular weight of 328.20 g/mol and a molecular formula of C21H28O3. Detailed PK parameters would require specific studies.
|
| Toxicity/Toxicokinetics |
Toxicological data for methyl 13-cis-4-oxoretinoate are likely similar to other retinoids, which are known teratogens and can cause significant side effects including mucocutaneous dryness, headache, hepatotoxicity, hyperlipidemia, and bone toxicity. Retinoids are strictly contraindicated during pregnancy due to severe teratogenic effects. Long-term use requires monitoring of liver function, lipid levels, and bone density. The compound is intended for research use only and has not been approved for clinical therapeutic use.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
