4-Vinyl-1-cyclohexene (VCH), is converted by multiple forms of cytochrome P450 (CYP) to two monoepoxides (4-vinyl-1-cyclohexene 1,2-epoxide [VCH-1,2-epoxide], 4-vinyl-1-cyclohexene 7,8-epoxide [VCH-7,8-epoxide]), and 4-vinyl-1-cyclohexene diepoxide (VCD). A greater degree of formation of these epoxides by female B6C3F1 mice as compared to Fischer

4-Vinylcyclohexene (VCH), an ovarian toxicant in mice, is known to irreversibly deplete ovarian follicles as a consequence of VCH diepoxide formation. Because ovotoxicity requires repeated dosing of VCH, the effect of consecutive daily doses of VCH (7.5 mmol/kg/day) on mouse
4-Vinylcyclohexene diepoxide (VCD) destroys preantral ovarian follicles in rats. Female 28-day Fisher 344 (F344) rats were dosed (30 days) with VCD (80 mg/kg per day, i.p.) or vehicle, and animals were evaluated for reproductive function at subsequent time points for

4-Vinylcyclohexene (VCH), an occupational chemical, causes destruction of small preantral follicles (F1) in mice. Previous studies suggested that VCH is bioactivated via cytochromes P450 (CYP450) to the ovotoxic, diepoxide metabolite, VCD. Whereas hepatic CYP450 isoforms 2E1, 2A, and 2B can

Microsomal epoxide hydrolase (mEH) is involved in the detoxification of xenobiotics that are or can form epoxide metabolites, including the ovotoxicant, 4-vinylcyclohexene (VCH). This industrial chemical is bioactivated by hepatic CYP450 to the diepoxide metabolite, VCD, which destroys mouse small
