吸入alpha-蒎烯对映体后,研究了蒎烯醇的尿液排泄。健康的男性受试者在进行轻度运动的同时,暴露于10、225或450毫克/立方米(+)alpha-蒎烯或450毫克/立方米(-)alpha-蒎烯2小时。在暴露后收集呼出的空气样本,并在蒎烯暴露前后收集尿液样本。两种蒎烯的呼吸道消除相似;在450毫克/立方米的浓度下,(+)alpha-蒎烯总吸收量的7.7%和(-)alpha-蒎烯总吸收量的7.5%被消除。暴露于(+)alpha-蒎烯后4小时,蒎烯醇的尿液排泄率在450毫克/立方米时为1.7%,在10毫克/立方米剂量时为3.8%。(-)alpha-蒎烯的尿液排泄率相似。排泄数据的半对数图表明存在多个消除(+)alpha-蒎烯和(-)alpha-蒎烯的速率常数。在2小时暴露后,大部分蒎烯醇在20小时内被消除。未改变的alpha-蒎烯的肾排泄率小于0.001%。尿液蒎烯醇的测定可能作为暴露于萜烯的生物暴露指数有用。
The urinary excretion of verbenols after inhalation of alpha-pinene enantiomers was studied. Healthy male subjects were exposed to 10, 225, or 450 mg/cu m (+)alpha-pinene or 450 mg/cu m (-)alpha-pinene for 2 hr while performing light exercise. Exhaled air samples were collected after exposure, and urine samples were obtained before and after pinene exposure. Respiratory elimination of both pinenes was similar; at a concn of 450 mg/cu m, 7.7% of the total uptake of (+)alpha-pinene and 7.5% of the total uptake of (-)alpha-pinene was eliminated. Urinary excretion of verbenol 4 hr after exposure to (+)alpha-pinene ranged from 1.7% at 450 mg/cu m to 3.8% at a dose of 10 mg/cu m. Urinary excretion of (-)alpha-pinene was similar. A semilogarithmic plot of the excretion data suggested the existence of more than one rate constant for the elimination of (+)alpha-pinene and (-)alpha-pinene. Most of the verbenols were eliminated within 20 hr after a 2 hr exposure. The renal excretion of unchanged alpha-pinene was less than 0.001%. The determination of urinary verbenols may be useful as a biological exposure index for exposure to terpenes.

The biotransformation of (+)-, (-)-, and (+-)-alpha-pinenes, (-)-beta-pinene (nopinene), (-)-cis-pinane, (+)-3-carene, (-)-cis-carane, myrcene, and p-cymene in rabbits was investigated. The major metabolites were as follows: (-)-trans-verbenol from (+)-, (-)-, and (+/-)-alpha-pinenes; (-)-10-pinanol and (-)-1-p-menthene-7,8-diol from (-)-beta-pinene; (-)-alpha-terpineol and (-)-trans-sobrerol from (-)-cis-pinane; (-)-m-mentha-4,6-dien-8-ol, 3-caren-9-ol, (-)-3-carene-9-carboxylic acid, and 3-carene-9,10-dicarboxylic acid from (+)-3-carene; carane-9,10-dicarboxylic acid from (-)-cis-carane; and myrcene-3(10)-glycol, myrcene-1,2-glycol, uroterpenol, and p-cymene-9-carboxylic acid from p-cymene. These metabolisms include allylic oxidation, epoxidation, stereoselective gem-dimethyl hydroxylation and its oxidation, cleavage of a conjugated double bond by epoxidation, and regioselective oxidation, some of which are not found usually in chemical reactions, and due to which various new compounds were determined. This biotransformation of the monoterpene hydrocarbons gave some insect pheromones in high yield.

松节油(α-蒎烯)在人体中的毒物动力学进行了研究。研究组由8名健康男性组成,平均年龄31岁。他们在吸入室中以0、10、225或450 mg/m³的(+)-α-蒎烯或450 mg/m³的(-)-α-蒎烯暴露2小时。在暴露期间,他们在自行车测功机上以50瓦的速率进行运动。(+)-α-蒎烯(-)-α-蒎烯的平均肺摄取量达到了暴露浓度的59%。绝对摄取量随浓度线性增加。血液中α-蒎烯浓度最初迅速上升,然后逐渐减少。暴露结束时血液中的平均浓度与吸入浓度线性相关。α-蒎烯从血液中的消除是三阶段的。吸入的(+)-α-蒎烯在三个阶段的消除半衰期分别为4.8、39和695分钟。(-)-α-蒎烯的消除半衰期为5.6、40和555分钟。未改变的α-蒎烯的累积尿排泄量不到每剂量的0.001%。(+)-α-蒎烯(-)-α-蒎烯的呼吸道消除分别为总摄取量的7.7%和7.5%。五名受试者抱怨眼睛、鼻子和喉咙刺激。没有看到与暴露相关的肺功能变化。在测试的浓度下,肝脏代谢α-蒎烯的能力没有超过。(+)-α-蒎烯(-)-α-蒎烯表现出相似的药代动力学行为。α-蒎烯易于代谢,未改变的α-蒎烯的消除非常低。
The toxicokinetics of alpha-pinene (a-pinene) were studied in humans. The study group consisted of eight healthy males, average age 31 years. They were exposed to 0, 10, 225, or 450 mg/cu m (+)-alpha-pinene or 450 mg/cu m (-)-alpha-pinene for 2 hr in an inhalation chamber. During exposure they exercised on a cycle ergometer at the rate 50 watts. Average pulmonary uptake of (+)-alpha-pinene and (-)-alpha-pinene amounted to 59% of the exposure concn. Absolute uptake increased linearly with concn. Blood alpha-pinene concn increased rapidly at first then tapered off. Mean blood concn at the end of exposure were linearly related to inhaled concn. Elimination of alpha-pinene from the blood was triphasic. Half times for elimination of inhaled (+)-alpha-pinene from the blood during the three phases were 4.8, 39, and 695 minutes. Elimination half times fo (-)-alpha-pinene were 5.6, 40, and 555 minutes. Cumulative urinary excretion of unchanged alpha-pinene amounted to less than 0.001% of each dose. Respiratory elimination of (+)-alpha-pinene and (-)-alpha-pinene was 7.7 and 7.5% of total uptake, respectively. Five subjects complained of eye, nose, and throat irritation. No exposure related changes in lung function were seen. At the concn tested the capacity of the liver to metabolize alpha-pinene is not exceeded. (+)-alpha-Pinene and (-)-alpha-pinene show similar pharmacokinetic behavior. alpha-Pinene is readily metabolized and elimination of unchanged alpha-pinene is very low.

... Eight male volunteers were exposed to 450 mg/cu m turpentine by inhalation (2 hr, 50 W) in an exposure chamber. ...The mean relative uptakes of alpha-pinene, beta-pinene, and 3-carene were 62%, 66%, and 68% respectively, of the amount supplied. Between 2% and 5% of the net uptake was excreted unchanged in the expired air after the end of exposure. The mean blood clearance 21 hours after exposure (CL21hr) of alpha-pinene, beta-pinene and 3-carene, were 0.8, 0.5, and 0.4 l.per kg per hr, respectively. The mean half lives (t1/2) of the last phase of alpha-pinene, beta-pinene, and 3-carene averaged 32, 25, and 42 hours, respectively. The t1/2s agreed with previously calculated half lives from single exposures. The total blood clearance CL21hr of 3-carene found in this turpentine study was lower, and CL4hr of 3-carene was significantly lower than the values obtained from similar exposure to pure 3-carene. The subjects attending both exposure to turpentine and to pure alpha-pinene at 450 mg/cu m had lower CL4hr during the exposure to turpentine ...

制备方法与用途

蒊烯简介

蒎烯是松节油和众多植物精油的主要成分,其分子结构中同时存在双键、桥环和手性碳原子,是一类具有特殊结构且具有良好应用前景的化合物。近年来,α-蒎烯β-蒎烯在药物活性方面的研究报道备受关注,这不仅有助于完善这两种化合物的生物活性研究,也促进了相关药物活性衍生化合物的研发。

制备合成

α-蒎烯在松节油中的含量最高,在各地松节油产品中占75%以上甚至超过90%,通过蒸馏可直接将α-蒎烯从松节油中分离出来。利用其不同的性质,可以将其合成一系列精细化工原料或产品。
