4-Vinylcyclohexene dioxide (VCD), a metabolite of 4-vinylcyclohexene (VCH), is synthesized in industries as an intermediate diluent for epoxy resins and other epoxides[1]. VCD induces caspase-dependent apoptosis of oocytes in primordial and primary follicles[2]. VCD in low-dose has hormone-like effects and can activate primordial follicles, leading to rapid depletion of primordial follicles[2]. It can be used to study premature ovarian insufficiency and menopause[2][3].
4-Vinylcyclohexene dioxide (0.5, 1, 1.5, and 2mM; 24h) dose-dependently reduces the viability of goat ovarian granulosa cells (GCs), alters their cell cycle distribution, and triggers caspase-dependent apoptosis[2].
4-Vinylcyclohexene dioxide (100, 250 and 500mg/kg/day, 28 days, p.o.) enhanced lipid peroxidation in rats by increasing the malondialdehyde (MDA) levels in ovary and uterus[4]. 4-Vinylcyclohexene dioxide (100, 250 and 500mg/kg/day, 28 days, p.o.) significantly decreased the body weight gain and organo-somatic indices of the testes and epididymis in matured male Wistar rats[5].

4-Vinylcyclohexene dioxide(VCD)是4-乙烯基环己烯(VCH)的代谢产物,在工业上被合成为环氧树脂和其他环氧化物的中间稀释剂[1]。VCD诱导原始卵泡和初级卵泡中卵母细胞的caspase依赖性凋亡[2]。低剂量的VCD具有激素样作用,可以激活原始卵泡,导致原始卵泡迅速耗竭[2]。它可用于研究卵巢功能不全和更年期[2][3]。
4-Vinylcyclohexene dioxide(0.5、1、1.5和2mM,24小时)剂量依赖性地降低山羊卵巢颗粒细胞(GCs)的活力,改变其细胞周期分布,并引发caspase依赖性细胞凋亡[2]。
4-Vinylcyclohexene dioxide(100、250和500mg/kg/天,28天,口服)通过增加卵巢和子宫中的丙二醛(MDA)水平增强大鼠的脂质过氧化[4]。4-Vinylcyclohexene dioxide(100、250和500mg/kg/天,28天,口服)显著降低成熟雄性Wistar大鼠的体重增加和睾丸和附睾的器官体质指数[5]。
