代谢
通过体外实验,使用从哺乳动物肝脏中分离的微体,确定了将2-硝基丙烷(2-NP)氧化为丙酮和亚硝酸盐的酶系统。研究发现,经苯巴比妥预处理的大鼠肝脏微体中的细胞色素P-450可以与2-NP结合。随后报告称,经苯巴比妥或3-甲基胆蒽预处理的大鼠肝脏微体迅速催化2-NP氧化为丙酮和亚硝酸盐,后者产量大致相等。然而,令人惊讶的是,在低氧压力条件下,这一反应的速率并未降低。未经处理的对照组大鼠的制剂活性通常非常低。研究表明,大鼠的这种酶系统在代谢其他脂肪族硝基化合物方面是活跃的。...在使用小鼠进行研究时,研究人员得到了一些不同的结果。他们报告称,未经处理的小鼠肝脏微体迅速将2-NP脱硝为亚硝酸盐和丙酮,丙酮的产生至少是亚硝酸盐释放的两倍。这些作者认为多种形式的细胞色素P-450参与其中,并声称亚硝酸盐在反应混合物中被隔离,2-NP的脱硝可能涉及还原或至少非氧化途径以及氧化途径。他们还注意到,在测试的五种小鼠株中,肝脏微体酶促亚硝酸盐释放的速率存在很大差异。...未经诱导的兔肝微体能够脱硝一种与2-NP相关的化合物,2-硝基-1-苯基丙烷。除了氧化脱硝外,还在Wistar大鼠的培养肝细胞和中国仓鼠V79细胞中显示发生了还原途径。硝基还原通过细胞形成丙酮肟,即硝基硝基丙烷的互变异构体来表示。
The enzymatic system oxidizing 2-nitropropane (2-NP) to acetone and nitrite was identified through in vitro experiments using microsomes isolated from mammalian liver. /It was/ determined that cytochrome P-450, in liver microsomes from phenobarbital-pretreated rats, bound 2-NP. /It was/ subsequently reported that liver microsomes from rats pretreated with phenobarbital or 3-methylcholanthrene rapidly catalysed the oxidation of 2-NP to acetone and nitrite. The latter were produced in roughly equal quantities. Surprisingly, however, the rate of this reaction was not diminished under conditions of reduced oxygen pressure. The activity of preparations from untreated control rats was generally very low. /It was/ demonstrated that this enzyme system in rats was active in metabolizing other aliphatic nitro compounds. ...Working with mice, /researchers/ obtained somewhat different results. They reported rapid denitrification of 2-NP to nitrite and acetone by liver microsomes from untreated mice,and an acetone production at least twice the nitrite release. These authors suggested that multiple forms of cytochrome P-450 are involved, and claimed that nitrite is sequestered in the reaction mixture and that denitrification of 2-NP may involve a reductive or at least non-oxidative pathway as well as an oxidative pathway. They also noted large differences in the rates of hepatic microsomal enzymatic nitrite release among the five strains of mice tested. ...Hepatic microsomes from uninduced rabbits could denitrify a compound related to 2-NP, 2-nitro-1-phenylpropane. In addition to oxidative denitrification, a reductive pathway has been shown to occur in cultured hepatocytes from Wistar rats and in V79 Chinese hamster cells. Nitroreduction was indicated by the fact that the cells formed acetone oxime, the tautomeric form of nitrosopropane.

吸收、分配和排泄
[14C]-2-硝基丙烷(2-NP)的药物动力学在暴露于20或154 ppm的雄性大鼠中进行了研究。至少有40%的吸入化合物被吸收。通过气相色谱分析测量的2-NP血药浓度以明显的一级方式降低(半衰期= 48分钟)。放射性从血液中双相消除的半衰期是两到四倍长,表明代谢物有更大的积累潜力。主要的排泄途径是呼出的空气。大约一半的给药放射性以14CO2的形式回收。在两个暴露浓度下观察到的动力学参数的许多差异表明,在154 ppm及更高浓度下存在非线性动力学。男性和女性在摄取或呼出过程方面没有差异,但代谢过程不同。一级、低亲和力但高容量代谢途径在女性中活性超过两倍。在暴露浓度高达180 ppm时,可饱和途径在女性中占主导地位,但在男性中仅限于60 ppm。因为男性对2-NP吸入产生的肝毒性、遗传毒性和致癌性更敏感,所以得出结论,这些效应是由一级途径产生的代谢物引起的。
The pharmacokinetics of [14C]-2-nitropropane (2-NP) were studied in male rats exposed for 6 hr to 20 or 154 ppm. At least 40% of the inhaled compound was absorbed. Blood concentrations of 2-NP measured by gas chromatographic analysis decreased in an apparent first order manner (half life = 48 min). Half lives for the biphasic elimination of radioactivity from blood were two to four times longer, indicating that metabolites have a greater potential to accumulate. The major route of excretion was the expired air. About half of the administered radioactivity was recovered as 14CO2. Numerous differences in kinetic parameters observed at the two exposure concentrations indicated nonlinear kinetics at 154 ppm and higher.There were no differences in uptake or exhalation processes between males and females, but metabolic processes differed. A first-order, low-affinity but high capacity metabolic pathway was more than twice as active in females. The saturable pathway was predominant in females at exposure concentrations up to 180 ppm but only up to 60 ppm in males. Because males are more sensitive to hepatoxicity, genotoxicity, and carcinogenicity produced by inhalation of 2-NP, /it was/ concluded that these effects are produced by the metabolite resulting from the first-order pathway.

吸收、分配和排泄
在暴露于728 mg/m³(200 ppm)浓度3小时后,血浆中大约含有0.4%的2-硝基丙烷(2-NP)和7.2%的吸入2-NP的代谢物。这些代谢物主要是丙酮,但也包括少量异丙醇。这些百分比是根据实验结果和对实验室大鼠的规范性数据估算的,并且支持2-NP快速肺部吸收,因为不考虑2-NP及其代谢物在体内其他部位的隔离以及暴露期间代谢的2-NP的损失。
...Immediately following exposure to 728 mg/cu m (200 ppm) for 3 hr, plasma contained approximately 0.4% as 2-nitropropane (2-NP) and 7.2% as metabolitesof the 2-NP inhaled. The metabolites were mainly acetone but also included a small amount of isopropanol. These percentages were estimated from the results ... and normative data for the laboratory rat, and support rapid pulmonary uptake of 2-NP since 2-NP and its metabolites sequestered elsewhere in the body and loss of metabolized 2-NP during exposure were not considered.

吸收、分配和排泄
对大鼠经腹腔注射2-硝基丙烷(2-NP)的吸收速率进行了研究。注射25 mg/kg剂量后10分钟,血液中含有所给剂量的3.3%的2-NP和1.9%的代谢物、丙酮和异丙醇,表明吸收率超过了5.2%,因为在这最初的时期内,假定部分剂量已经从体内和体内的其他组织中丢失。这些百分比是根据实验室大鼠的数据和标准数据估算出来的。50 mg/kg剂量的结果部分不同。10分钟的平均值较低,且标准偏差很大。这可能是由于大鼠在最初对2-NP的吸收速率上有很大差异,或者是实验问题,例如注射到胃肠腔而不是腹膜腔。注射后10分钟,血液中仅含有剂量的1.4%的2-NP和1.3%的丙酮和异丙醇。这些数据表明,从腹膜腔吸收相对较快,并提示50 mg/kg剂量相对较慢的吸收可能反映了吸收机制的饱和,因为血浆中的初始浓度并未超过25 mg/kg剂量后的浓度。
The rate of 2-nitropropane (2-NP) uptake by rats from intraperitoneal injection was examined. Ten minutes after an injection of 25 mg/kg, the blood plasma contained 3.3% of the dose as 2-NP and 1.9% as metabolites, acetone, and isopropanol, indicating an uptake of >5.2% since presumably some of the dose was already lost from the body and to other tissues in the body during this initial period. These percentages were estimated from the data ... and normative data for the laboratory rat. A dose of 50 mg/kg yielded partially dissimilar results. The 10-min average value was low and also had a very large standard deviation. This may have reflected large differences among the rats in their initial uptake rates for 2-NP or an experimental problem such as injection into the gastrointestinal tract rather than the peritoneal cavity. Blood plasma contained, 10 min after injection, only 1.4% of the dose as 2-NP and 1.3% as acetone and isopropanol. These data indicate that uptake from the peritoneal cavity is fairly rapid, and suggest that the relatively slower uptake of the 50-mg/kg dose may have reflected saturation of the uptake mechanisms, since initial concentrations in the plasma did not exceed those following the 25-mg/kg dose.

    Convenient synthetic method for 4-arylethylpyrazoles and 4-styrylpyrazoles was developed using $\alpha}$-alkenyl-$\alpha},\beta}$-enones readily accessed from the Morita-Baylis-Hillman reaction. For the synthesis of 4-arylethylpyrazole, the reactions with arylhydrazines needed to be carried out in o-dichlorobenzene under $N_2$ balloon atmosphere. On the other hand, 4-styrylpyrazoles required the reactions in ethanol under $O_2$ balloon atmosphere.
    开发了一种便捷的合成4-芳基乙基吡唑和4-苯乙烯基吡唑的方法,该方法利用了可通过Morita-Baylis-Hillman反应轻易获得的α-烯基-α,β-烯酮。对于4-芳基乙基吡唑的合成,需在氮气球气氛下于邻二氯苯中进行与芳基肼的反应。另一方面,4-苯乙烯基吡唑的合成则需要将反应置于乙醇中并在氧气球气氛下进行。
