代谢
JP-8喷气燃料是由芳香烃和脂肪烃组成的复杂混合物。这项研究旨在确定半挥发性正构烷烃壬烷C9、癸烷C10和十四烷C14)在大鼠肝脏微粒体氧化中的体外代谢速率常数。通过气相色谱测量母化合物的消失来评估代谢。将不同浓度的正构烷烃与成年雄性F-344大鼠的肝脏微粒体一起孵化。壬烷癸烷的非线性动力学常数分别为V(max)(nmol/mg蛋白质/min)= 7.26 +/- 0.20和2.80 +/- 0.35,K(M)(uM)= 294.83 +/- 68.67和398.70 +/- 42.70。通过内在清除率(V(max)/K(M))评估的代谢能力,壬烷大约是癸烷的四倍(0.03 +/- 0.005比0.007 +/- 0.001)...这些结果表明,正构烷烃的代谢清除率与其链长呈负相关。这些代谢速率常数将用于更新现有的非烷和癸烷的基于生理的药代动力学(PBPK)模型,作为开发JP-8的PBPK模型的一部分。
Jet propellant 8 (JP-8) jet fuel is a complex mixture of aromatic and aliphatic hydrocarbons. The aim of this study was to determine in vitro metabolic rate constants for semivolatile n-alkanes, nonane (C9), decane (C10), and tetradecane (C14), by rat liver microsomal oxidation. The metabolism was assessed by measuring the disappearance of parent compound by gas chromatography. Various concentrations of n-alkanes were incubated with liver microsomes from adult male F-344 rats. Nonlinear kinetic constants for nonane and decane were V(max) (nmol/mg protein/min) = 7.26 +/- 0.20 and 2.80 +/- 0.35, respectively, and K(M) (uM) = 294.83 +/- 68.67 and 398.70 +/- 42.70, respectively. Metabolic capacity as assessed by intrinsic clearance (V(max)/K(M)) was approximately four-fold higher for nonane (0.03 +/- 0.005) than for decane (0.007 +/- 0.001)... These results show a negative correlation between metabolic clearance and chain length of n-alkanes. These metabolic rate constants will be used to update existing physiologically based pharmacokinetic (PBPK) models for nonane and decane as part of developing a PBPK model for JP-8.

代谢
壬烷,是喷气推进燃料8(JP-8)的一个组成部分,在混合人肝微粒体(pHLM)的作用下代谢为2-壬醇2-壬酮。细胞色素P450(CYP)同种物1A2、2B6和2E1将壬烷代谢为2-壬醇,而酒精脱氢酶、CYPs 2B6和2E1将2-壬醇代谢为2-壬酮壬烷2-壬醇睾酮雌二醇或N,N-二乙基-m-甲苯酰胺(DEET)的代谢没有显著影响,但抑制了甲萘威的代谢。JP-8对睾酮雌二醇甲萘威的代谢有适度的抑制作用,但对DEET的代谢影响更为显著。JP-8被显示能抑制CYPs 1A2和2B6介导的DEET代谢,这表明至少JP-8的一些成分可能被CYPs 1A2和/或2B6代谢。
Nonane, a component of jet-propulsion fuel 8 (JP-8), is metabolized to 2-nonanol and 2-nonanone by pooled human liver microsomes (pHLM). Cytochrome P450 (CYP) isoforms 1A2, 2B6 and 2E1 metabolize nonane to 2-nonanol, whereas alcohol dehydrogenase, CYPs 2B6 and 2E1 metabolize 2-nonanol to 2-nonanone. Nonane and 2-nonanol showed no significant effect on the metabolism of testosterone, estradiol or N,N-diethyl-m-toluamide (DEET), but did inhibit carbaryl metabolism. JP-8 showed modest inhibition of testosterone, estradiol and carbaryl metabolism, but had a more significant effect on the metabolism of DEET. JP-8 was shown to inhibit CYPs 1A2 and 2B6 mediated metabolism of DEET, suggesting that at least some of the components of JP-8 might be metabolized by CYPs 1A2and/or 2B6.

代谢
先前的研究已经证实,吡硫磷(CPS)、氟虫腈和非烷都可以被人肝微粒体(HLM)和多种细胞色素P450(CYP)同种物代谢。然而,这三种底物之间的代谢相互作用尚未被描述。在本研究中,探讨了CPS与HLM或CYP同种物共同培养或预培养对氟虫腈或非烷作为底物的影响。在共同培养和预培养实验中,CPS显著抑制了HLM对氟虫腈或非烷的代谢,尽管CPS对氟虫腈代谢的抑制效果比对非烷更有效。CPS显著抑制了CYP3A4对氟虫腈以及CYP2B6对非烷的代谢。在两种情况下,与CPS预培养相比,共同培养导致的抑制更大,这表明这种抑制是基于机制的。
Previous studies have established that chlorpyrifos (CPS), fipronil, and nonane can all be metabolized by human liver microsomes (HLM) and a number of cytochrome P450 (CYP) isoforms. However, metabolic interactions between these three substrates have not been described. In this study the effect of either coincubation or preincubation of CPS with HLM or CYP isoforms with either fipronil or nonane as substrate was investigated. In both co- and preincubation experiments, CPS significantly inhibited the metabolism of fipronil or nonane by HLM although CPS inhibited the metabolism of fipronil more effectively than that of nonane. CPS significantly inhibited the metabolism of fipronil by CYP3A4 as well as the metabolism of nonane by CYP2B6. In both cases, preincubation with CPS caused greater inhibition than coincubation, suggesting that the inhibition is mechanism based.

Fischer 344雄性大鼠通过灌胃给予正壬烷后,尿液中含有的代谢物包括γ-戊内酯δ-己内酯2,5-己二酮、δ-庚内酯、1-庚醇2-壬醇3-壬醇4-壬醇4-壬酮和5-甲基-2-(3-氧代丁基)呋喃。代谢过程强烈倾向于形成单醇和内酯,这些是适当取代的羟基羧酸的产品。使用气相色谱(GC)和气相色谱/质谱(GC/MS)识别了代谢物。高压液相色谱(HPLC)使得能够在给予正壬烷的大鼠尿液中检测到丁二酸戊二酸这两种二羧酸
The urinary metabolites of n-nonane in male Fischer 344 rats, after administering the hydrocarbon by gavage, included gamma-valerolactone, delta-hexanolactone, 2,5-hexanedione, delta-heptanolactone, 1-heptanol, 2-nonanol, 3-nonanol, 4-nonanol, 4-nonanone and 5-methyl-2-(3-oxobutyl)furan. Metabolism strongly favored the formation of monoalcohols and lactones, which are the products of appropriately substituted hydroxy carboxylic acids. The metabolites were identified using gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). High pressure liquid chromatography (HPLC) permitted the detection of the dicarboxylic acids malonic acid and glutaric acid in the n-nonane dosed rat urines.

吸收、分配和排泄
尽管这种暴露场景是职业常态,但经皮涂抹的喷气燃料碳氢化合物(HC)通过预先暴露于JP-8的皮肤的吸收尚未被研究。将猪暴露于浸泡了JP-8的棉布1天和4天,并每天重复暴露。预处理和未处理的皮肤随后被切割并放置在体外扩散细胞中。五个暴露皮肤的细胞和四个未暴露皮肤的细胞被用含有非烷、癸烷十一烷十二烷十三烷十四烷十五烷十六烷乙基苯邻二甲苯、三甲基苯(TMB)、环己基苯CHB)、二甲基萘DMN)的14种不同HC的+乙醇(50:50)作为稀释剂的混合物处理。另外五个含有JP-8暴露皮肤的细胞只被稀释剂处理,以确定喷气燃料HC在皮肤中的残留潜力。数据显示,通过1天和4天JP-8预暴露皮肤的吸收,非烷、十一烷十二烷十三烷的吸收分别增加了2-3倍和3-4倍...计算了研究HC的通量、扩散率和渗透性参数。燃料预暴露皮肤中HC吸收增加的可能机制可能是通过电子显微镜指示的角质层脂质提取。这项研究表明,喷气燃料HC的单次剂量应用数据不能用于预测重复暴露的毒性潜力,并且对于某些化合物,可能在暴露后几天内持续吸收。
The percutaneous absorption of topically applied jet fuel hydrocarbons (HC) through skin previously exposed to JP-8 has not been investigated, although this exposure scenario is the occupational norm. Pigs were exposed to JP-8 soaked cotton fabrics for 1 and 4 days with repeated daily exposures. Pre-treated and untreated skin was then dermatomed and placed in in-vitro diffusion cells. Five cells with exposed skin and four cells with unexposed skin were dosed with a mixture of 14 different HC consisting of nonane, decane, undecane, dodecane, tridecane, tetradecane, pentadecane, hexadecane, ethyl benzene, o-xylene, trimethyl benzene (TMB), cyclohexyl benzene (CHB), naphthalene, and dimethyl naphthalene (DMN) in water + ethanol (50:50) as diluent. Another five cells containing JP-8 exposed skin were dosed with diluent only in order to determine the residue potential of jet fuel HC in skin. The data indicated that there was 2-3-fold and 3-4-fold increase in absorption of nonane, undecane, dodecane and tridecane through 1 and 4 days JP-8 pre-exposed skin respectively... The absorption parameters of flux, diffusivity and permeability were calculated for the studied HC. The possible mechanism of increased HC absorption in fuel pre-exposed skin may be via lipid extraction from stratum corneum as indicated by electron microscopy. This study suggests that single dose application data for jet fuel HC cannot be used to predict the toxic potential for repeated exposures and that for certain compounds, persistent absorption may occur days post-exposure.

    Trialkylsilylium cation equivalents partnered with halogenated carborane anions (such as Et(3)Si[HCB(11)H(5)Cl(6)]) function as efficient and long-lived catalysts for hydrodehalogenation of C-F, C-Cl, and C-Br bonds with trialkylsilanes as stoichiometric reagents. Only C(sp(3))-halogen bonds undergo this reaction. The range of C-F bond-containing substrates that participate in this reaction is quite broad and

    Cyanoborohydrides are efficient reagents in the reductive addition reactions of alkyl iodides and electron-deficient olefins. In contrast to using tin reagents, the reaction took place chemoselectively at the carbon–iodine bond but not at the carbon–bromine or carbon–chlorine bond. The reaction system was successfully applied to three-component reactions, including radical carbonylation. The rate constant

    An improved method for the decarbonylation of aliphatic ­aldehydes by using a commercially available Pd/C catalyst is described. The reaction conditions are suitable for linear, cyclic, or sterically demanding substrates, as they afford the corresponding alkanes in yields of up to 99%. In addition, this Pd/C-catalyzed method exhibits good functional-group tolerance. A comparison of previously reported
