代谢

对雄性白化大鼠口服给予alpha-terpineol的代谢命运进行了研究，并对其对肝脏微粒体细胞色素P-450系统的影响进行了探讨。为了进行代谢研究，每天一次给予alpha-terpineol，连续20天，剂量为600mg/kg体重；细胞色素P-450研究涉及最多9天的给药。...分离出的中性馏分显示存在一个主要成分（alpha-terpineol）和两个次要化合物。其中一个次要化合物被鉴定为p-薄荷烷-1,2,8-三醇。进一步的研究揭示了橄榄酸和二氢橄榄酸的甲基酯的存在。碳-1位置的烯丙基甲基酯的氧化似乎是主要的代谢途径。考虑到烯丙基甲基团在C-7位置的氧化可能发生在1,2-双键还原之前。给予alpha-terpineol后，肝脏微粒体细胞色素P-450的水平在给药1、2、3、6和9天后分别增加了72%、104%、90%、54%和52%。在重复给药的前3天内，肝脏微粒体NADPH-细胞色素c-还原酶的水平有所中度增加。对细胞色素b5和NADH-细胞色素c-还原酶没有显著影响。作者得出结论，alpha-terpineol的烯丙基甲基氧化是其在大鼠体内代谢转化的主要途径。特别注意到，在橄榄酸形成二氢橄榄酸的过程中，内环双键的还原。

The metabolic fate of alpha-terpineol administered orally to male albino-rats was investigated, and its effects on the liver microsomal cytochrome-P-450 system were studied. For metabolic studies, alpha-terpineol was given once daily for 20 days at a dose of 600mg/kg bw; cytochrome-P-450 studies involved dosing for up to 9 days. ...The neutral fraction isolated showed the presence of one major (alpha-terpineol) and two minor compounds. One of the minor compounds was identified as p-menthane-1,2,8-triol. Further study revealed the presence of the methyl esters of oleuropeic-acid and dihydrooleuropeic-acid. Allylic oxidation of C-1 methyl esters appeared to be the major metabolic pathway. It was considered likely that the allylic methyl group at C-7 was oxidized prior to the reduction of the 1,2-double bond. Administration of alpha-terpineol increased the levels of liver microsomal cytochrome-P-450 by 72, 104, 90, 54, and 52% after 1, 2, 3, 6, and 9 days of dosing, respectively. A moderate incr was noted in the levels of liver microsomal NADPH-cytochrome-c-reductase during the first 3 days of repeated dosing. No significant effect was noted on cytochrome-b5 and NADH-cytochrome-c-reductase. The authors conclude that the allylic methyl oxidation of alpha-terpineol is the major route for its metabolic transformation in the rat. The reduction of the endocyclic double bond was specifically noted in the formation of dihydrooleuropeic-acid from oleuropeic-acid.

代谢

松节油通过普通夜蛾（Spodoptera litura）幼虫的生物转化被研究。将松节油混合在人造饲料中，然后将饲料喂给S. litura的幼虫（第四至第五龄幼虫）。从幼虫的粪便中分离出代谢物并进行光谱分析。主要代谢物是7-羟基-松节油（p-薄荷-1-烯-7,8-二醇）和橄榄酸（8-羟基-p-薄荷-1-烯-7-酸）。幼虫粪便中的肠道细菌没有参与松节油的代谢。松节油被S. litura幼虫优先在C-7位置（烯丙基甲基基团）氧化。

Biotransformation of alpha-terpineol by the common cutworm (Spodoptera litura) larvae was investigated. alpha-Terpineol was mixed in an artificial diet, and the diet was fed to the larvae (fourth-fifth instar) of S. litura. Metabolites were isolated from the frass and analyzed spectroscopically. Main metabolites were 7-hydroxy-alpha-terpineol (p-menth-1-ene-7,8-diol) and oleuropeic acid (8-hydroxy-p-menth-1-en-7-oic acid). Intestinal bacteria from the frass of larvae did not participate in the metabolism of alpha-terpineol. alpha-Terpineol was preferentially oxidized at the C-7 position (allylic methyl group) by S. litura larvae.

代谢

以下是细长金黄杆菌对 alpha-terpineol 的新陈代谢细节。这种微生物对 alpha-terpineol 的降解产生了一系列酸性代谢物和中性代谢物。在酸性代谢物中，已经鉴定出了 beta-异丙基戊二酸、1-羟基-4-异丙烯基环己烷-1-羧酸、8-羟基枯酸、橄榄酸、枯酸和 p-异丙烯基苯甲酸。鉴定出的中性代谢物包括柠檬烯、p-对伞花烃-8-醇、2-羟基桉叶油醇和尿 terpenol。...看起来细长金黄杆菌至少通过三种不同的途径降解 alpha-terpineol。其中一条途径似乎是通过橄榄酸进行的，第二条途径可能是由 alpha-terpineol 的芳构化启动的。第三条途径可能涉及从 alpha-terpineol 形成柠檬烯及其进一步的代谢。

Details of the metabolism of alpha-terpineol by Pseudomonas incognita are presented. Degradation of alpha-terpineol by this organism resulted in the formation of a number of acidic and neutral metabolites. Among the acidic metabolites, beta-isopropyl pimelic acid, 1-hydroxy-4-isopropenyl-cyclohexane-1-carboxylic acid, 8-hydroxycumic acid, oleuropeic acid, cumic acid, and p-isopropenyl benzoic acid have been identified. Neutral metabolites identified were limonene, p-cymene-8-ol, 2-hydroxycineole, and uroterpenol. ... /I/t appears that P. incognita degrades alpha-terpineol by at least three different routes. While one of the pathways seems to operate via oleuropeic acid, a second may be initiated through the aromatization of alpha-terpineol. The third pathway may involve the formation of limonene from alpha-terpineol and its further metabolism.

代谢

在一条次要途径中，alpha-terpineol 的内环烯烃被环氧化，然后水解产生一个三醇代谢物 1,2,8-三羟基-对-孟烷，这也曾报道过在人类意外口服含有 alpha-terpineol 的松油消毒剂后的情况。

In a minor pathway, the endocyclic alkene of alpha-terpineol is epoxidized and then hydrolysed to yield a triol metabolite 1,2,8-trihydroxy- para-menthane, which was also reported in humans after inadvertent oral ingestion of a pine-oil disinfectant containing alpha-terpineol.

识别和使用：alpha-松油醇是一种无色固体。它用于香水制造；将脂肪变性以用于肥皂制造；烃类溶剂；用于树脂、纤维素酯和醚的溶剂；消毒剂；抗氧化剂；药物；香料成分。在美国，它目前没有注册为农药使用，但批准的农药用途可能会定期更改，因此必须咨询联邦、州和地方当局以获取当前批准的用途。人类暴露和毒性：在人类受试者中，alpha-松油醇具有较低的刺激性但强烈的气味。据报道，两名皮炎患者对alpha-松油醇敏感，尽管尝试使用稀释的alpha-松油醇溶液在志愿者中诱导皮肤敏感化并未成功。文献中描述的两起死亡案例均是由于意外摄入含有松油的产品，归因于异丙醇和1-alpha-松油醇的联合毒性。评估了互叶白千层精油（茶树油）对体外激活的人外周血白细胞产生氧衍生活性物种的调节特性，发现alpha-松油醇显著抑制了fMLP-、LPS-和PMA刺激的超氧阴离子产生；这表明这些成分在炎症期间对细胞类型的选择性调节潜力。动物研究：在兔子中，纯alpha-松油醇是一种中等程度的皮肤刺激物。在急性口服暴露后，啮齿类动物通常报告低毒性。研究了松油（一种商业上可用的消毒剂）在马中静脉给药后的急性毒性。alpha-松油醇被识别为松油的主要成分。在静脉注射0.1 mL/kg后，从马的组织中回收了alpha-松油醇，由于大量肺水肿，几分钟内死亡。在大鼠重复口服给药后，看到了肝脏影响的间接证据。在小鼠（通过注射治疗）的有限研究中没有看到肺致癌性的迹象。Terpineol在没有和有激活的情况下，都导致了Salmonella TA102测试菌株的his+回复突变体数量略有但与剂量相关的增加。研究了terpineol对大鼠坐骨神经复合动作电位（CAP）的影响。Terpineol诱导了CAP的剂量依赖性阻塞。

IDENTIFICATION AND USE: alpha-Terpineol is a colorless solid. It used in perfumes manufacturing; denaturing fats for soap manufacture; hydrocarbon solvent; solvent for resins, cellulose esters, and ethers; disinfectants; antioxidants; medicines; constituent of flavorings. It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. HUMAN EXPOSURE AND TOXICITY: In human subjects, alpha-terpineol had a low irritative potency but a strong odor. Two dermatitis patients were reported to be sensitized to alpha-terpineol, although attempts to induce skin sensitization in volunteers using a dilute solution of alpha-terpineol were unsuccessful. Two fatalities described in the literature were both due to accidental ingestion of a pine oil-containing products and were attributed to combined toxicity of isopropanol and 1-alpha-terpineol. The regulatory properties of the essential oil of Melaleuca alternifolia (tea tree oil) on the production of oxygen derived reactive species by human peripheral blood leukocytes activated in vitro was evaluated and found that alpha-terpineol significantly suppressed fMLP-, LPS- and PMA-stimulated superoxide production; suggesting the potential for selective regulation of cell types by these components during inflammation. ANIMAL STUDIES: In rabbits neat alpha-terpineol was a moderate skin irritant. Following acute oral exposure, a low toxicity was generally reported in rodents. Acute toxicity of pine oil (a commercially available disinfectant) after intravenous administration in horses was studied. alpha-Terpineol was identified as a major constituent of pine oil. alpha-Terpineol was recovered from equine tissues after iv injection of 0.1 mL/kg, death due to massive pulmonary edema occurred within minutes. Indirect evidence of liver effects was seen in rats given repeated oral doses. No indication of lung carcinogenicity was seen in a limited study in mice (treated by injection). Terpineol caused a slight but dose-related increase in the number of his+ revertants with Salmonella TA102 tester strain both without and with activation. The effects of terpineol on the compound action potential (CAP) of rat sciatic nerve were studied. Terpineol induced a dose-dependent blockade of the CAP.

  Hydration of alkenes using first row transition metals (Fe, Co, Mn) under oxygen atmosphere (Mukaiyama‐type hydration) is highly practical for alkene functionalization in complex synthesis. Different hydration protocols have been developed, however, control of the stereoselectivity remains a challenge. Herein, highly diastereoselective Fe‐catalyzed anaerobic Markovnikov‐selective hydration of alkenes

  在氧气气氛下使用第一行过渡金属（Fe、Co、Mn）进行烯烃水合（Mukaiyama 型水合）对于复杂合成中的烯烃官能化非常实用。已经开发了不同的水合方案，然而，立体选择性的控制仍然是一个挑战。在此，报道了使用硝基芳烃作为氧化试剂的高度非对映选择性铁催化的烯烃厌氧马尔可夫尼科夫选择性水合。硝基部分在自由基化学中尚未得到很好的探索，并且已知硝基芳烃可以抑制自由基过程。我们的研究结果表明廉价的硝基芳烃作为自由基转化中的氧供体的潜力。制备的仲醇和叔醇具有优异的马尔可夫尼科夫选择性。该方法具有官能团耐受性大的特点，也适用于后期化学官能化。厌氧方案在反应效率和选择性方面优于现有的水合方法。
