毒理性
鉴定和使用:诺特卡酮能形成晶体;然而,商业产品是无色至淡黄色的液体。它用于饮料中赋予葡萄柚风味;与其他柑橘油一起用于香精配方。潜在的生物基杀虫剂,用于杀死蚂蚁、白蚁、蚊子、蟑螂和蜱虫,包括Ixodes scapularis(黑腿蜱),其叮咬可以传播细菌,导致人类和其他动物患上网格病。人类暴露和毒性:没有找到人类数据。动物研究:在一项为期28天的研究中,雄性和雌性大鼠通过口服灌胃每天给予10毫克/千克体重的诺特卡酮。没有报告出现临床可观察的毒性迹象。组织病理学检查显示,接受10毫克/千克体重诺特卡酮治疗的雄性大鼠的肾小管上皮细胞内积聚了球形嗜酸性物质。这一发现与透明滴状肾病的存在一致,这是由于肾近端小管上皮细胞内α-2u-球蛋白过度积聚所致。近端小管上皮细胞内α-2u-球蛋白的积聚被认为对人类没有相关性。生态毒性研究:诺特卡酮的封装提高了对蜱虫控制的毒性,减少了诺特卡酮的挥发性,并减少了植物的植物毒性。
IDENTIFICATION AND USE: Nootkatone forms crystals; however, commercial product is a colorless to yellowish liquid. It is used in beverages to impart grapefruit flavor; in fragrance compositions with other citrus oils. Potential bio-based pesticide to kill ants, termites, mosquitoes, cockroaches, and ticks, including Ixodes scapularis (blacklegged tick), whose bite can transmit bacteria that cause Lyme disease in humans and other animals. HUMAN EXPOSURE AND TOXICITY: No human data were found. ANIMAL STUDIES: In a 28-day study, rats (male and female) were given nootkatone at a dose of 10 mg/kg bw per day by oral gavage. No clinically observable signs of toxicity were reported. Histopathological examination revealed accumulation of globular eosinophilic material in the tubular epithelium of male rats treated with nootkatone at a dose of 10 mg/kg bw per day. This finding is consistent with the presence of hyaline droplet nephropathy, which results from the excessive accumulation of alpha-2u-globulin in renal proximal tubular epithelial cells. Accumulation of alpha-2u-globulin in the proximal tubular epithelium is considered to be of no relevance to humans. ECOTOXICITY STUDIES: Encapsulation of nootkatone improved toxicity for tick control, reduced nootkatone volatility, and reduced plant phytotoxicity.
