Prothioconazole

(Synonyms: JAU-6476)

Customer Review

Based on 1 Customer Validation

Prothioconazole is an orally active broad-spectrum fungicide. Prothioconazole weakly inhibits CaCYP51 activity in Candida albicans, with an apparent IC₅₀ of approximately 120 μM. Prothioconazole disrupts Microtubule stability by reducing the acetylation level of α-tubulin. Prothioconazole induces Mitochondrial dysfunction, oxidative stress, DNA damage, and Apoptosis. Prothioconazole accumulates ¹⁴-methylated sterols and depletes ergosterol in cells, culture media, plants, and animals. Prothioconazole interferes with pyruvate metabolism and glycolysis/gluconeogenesis processes in mouse liver, downregulates Fasn mRNA expression, and induces hepatotoxicity and renal metabolic disorders. Prothioconazole reduces the fertility of female mice. Prothioconazole inhibits body weight gain and increases liver/kidney indices in mice. Prothioconazole can be used in studies related to candidiasis.

In Vitro

Prothioconazole shows weak binding affinity to purified *Candida albicans* CaCYP51, with an apparent dissociation constant K_d of 6.3 μM. It generates a type I difference spectrum instead of the typical type II difference spectrum produced by azole antifungal agents^[1].
Prothioconazole (100 μM) competitively inhibits the binding of Lanosterol (HY-W020033) to purified *Candida albicans* CaCYP51, increasing the apparent K_s of Lanosterol by 2.5-fold to 62.2 μM^[1].
Prothioconazole (0-100 μM) weakly inhibits CaCYP51 activity of Candida albicans in a cell-free system, with an apparent IC₅₀ of approximately 120 μM, and only achieves an inhibition rate of 45% at a concentration of 100 μM^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Prothioconazole (10 mg/kg/day; p.o.; daily; 30 days) exposure in female mice induces reproductive toxicity by disrupting oocyte maturation, fertilization, and early embryo development via mitochondrial dysfunction, oxidative stress, DNA damage, and apoptosis, reducing offspring numbers by ~34%^[2].
Prothioconazole (1-5 mg/kg BW/day; p.o.; daily; 28 days) administration to male ICR mice causes dose-dependent oxidative stress, metabolic disruption, and reduced growth phenotypes, with more severe effects observed in liver tissue compared to kidney tissue^[3].
Prothioconazole (1-5 mg/kg; p.o.; daily; 30 days) induces dose-dependent liver metabolic dysfunction and hepatotoxicity in female ICR mice, disrupting glycolipid metabolism via changes in key gene expression, metabolite levels, and liver histology^[4].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
