| Targets |
Epoxiconazole targets lanosterol 14α-demethylase (CYP51), a cytochrome P450 enzyme involved in ergosterol biosynthesis. It acts as a competitive inhibitor of CYP51, blocking the conversion of lanosterol to ergosterol. This inhibition disrupts fungal cell membrane integrity and function, leading to fungal growth inhibition and cell death.
|
|---|---|
| ln Vitro |
In vitro, Epoxiconazole inhibits lanosterol 14α-demethylase (CYP51) activity, blocking ergosterol biosynthesis in fungal cells. The compound demonstrates broad-spectrum antifungal activity against various plant pathogenic fungi. Specific IC50 values for CYP51 inhibition are available from enzymatic assays. Epoxiconazole shows potent activity against Ascomycetes, Basidiomycetes, and Deuteromycetes fungi.
|
| ln Vivo |
In vivo, Epoxiconazole is used as a broad-spectrum agricultural fungicide for the control of fungal diseases in cereals, fruits, and vegetables. It is applied as a foliar spray or seed treatment. The compound provides systemic and protective activity against a wide range of fungal pathogens, including Septoria, Fusarium, and Rhynchosporium species.
|
| Enzyme Assay |
The in vitro enzyme activity assay for Epoxiconazole involves measuring its inhibitory effect on lanosterol 14α-demethylase (CYP51) activity. Recombinant fungal CYP51 enzyme is incubated with varying concentrations of Epoxiconazole and its substrate, lanosterol, in the presence of NADPH. The extent of demethylation is measured by HPLC or mass spectrometry. The IC50 for CYP51 inhibition is determined from dose-response curves.
|
| Cell Assay |
In vitro cellular assays for Epoxiconazole involve treating cultured fungal cells with varying concentrations of the compound. Fungal growth is assessed by measuring optical density or colony formation. Ergosterol content in fungal cell membranes is measured by HPLC or spectrophotometry. The compound's antifungal activity is evaluated by comparing growth inhibition and ergosterol reduction to untreated controls.
|
| Animal Protocol |
In vivo animal experiments for Epoxiconazole typically use plant models of fungal infection rather than animals. Infected plants are treated with Epoxiconazole via foliar spray or seed treatment at various doses. Disease severity is assessed by measuring lesion size or fungal biomass. The compound's protective and curative activities are evaluated. As an agricultural fungicide, Epoxiconazole is not typically tested in animal models for efficacy.
|
| ADME/Pharmacokinetics |
Epoxiconazole has a molecular weight of 329.76 (C17H13ClF N3O). As a triazole fungicide, it is absorbed by plants and provides systemic protection. The compound is metabolized in plants and soil. In mammals, Epoxiconazole is metabolized by cytochrome P450 enzymes and excreted via urine and feces. Specific PK parameters in humans are not extensively documented.

| Toxicity/Toxicokinetics |
Toxicity Data
LC50 (Rat) > 5,300 mg/m3 Epoxiconazole has been extensively studied for its toxicological profile as an agricultural chemical. Potential adverse effects in mammals may include hepatotoxicity, reproductive toxicity, and endocrine disruption due to CYP51 inhibition. The compound is classified as a potential endocrine disruptor. Complete toxicology data are available from regulatory submissions for agricultural 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.
