代谢
Carworth farms, CF1雌鼠被通过腹腔注射给予p-aminopropiophenone(PAPP),剂量为10, 20, 30 mg PAPP/kg体重。使用湿化学方法在不同时间段分析尿液中的活性代谢物。PAPP以原形和乙酰衍生物的形式在尿液中排出。随着剂量的增加,PAPP剂量在尿液中的排出比例降低。
Carworth farms, CF1 female mice /were administered p-aminopropiophenone at/ doses /of/ 10, 20, 30 mg PAPP/kg bw by intraperitoneal injection. Wet chemistry methods were used to analyze an active metabolite in the urine at different time periods. PAPP was excreted in urine both unchanged and as the acetyl derivative. The proportion of the PAPP dose excreted in urine reduced with increasing dose.

乙基苯胺、对氯苯胺、对位和间位氨基丙酮、4-氨基联苯和2-氨基芴的N-羟基衍生物在注射后可在尿液中检测到。兔子以N-羟基衍生物的形式排泄了30%的对氨基丙酮和20%的4-氨基联苯。其他胺的N-羟基衍生物在尿液中的出现程度要小得多。豚鼠以N-羟基衍生物形式排泄的胺的比例比兔子要小;尿液中以N-羟基衍生物形式发现了15%的对氨基丙酮。狗只排泄了1%或更少的测试胺作为N-羟基衍生物。N-羟基-对氨基丙酮在很大程度上以共轭物的形式排泄,这种共轭物在酸性溶液中会分解。在广泛的剂量范围内,以N-羟基衍生物形式排泄的对氨基丙酮的比例是相同的。兔子的血液和尿液中N-羟基衍生物和硝基类似物的浓度关系与狗观察到的关系大相径庭。
The N-hydroxy derivatives of p-ethylaniline, p-chloroaniline, p- and m-aminopropiophenone, 4-aminobiphenyl, and 2-aminofluorene were found in the urine after injection. Rabbits excrete 30 per cent of the p-aminopropiophenone and 20 per cent of the 4-aminobiphenyl as N-hydroxy derivative. The N-hydroxy derivatives of the other amines appear in the urine to a much smaller extent. Guinea pigs excrete a smaller proportion of the amines as N-hydroxy derivative than rabbits; 15 per cent of p-amino-propiophenone was found in the urine as N-hydroxy derivative. Dogs excrete only 1 per cent or less of the amines tested as N-hydroxy derivative. N-Hydroxy-p-amino-propiophenone is excreted to a large extent as a conjugate which is split in acid solution. The fraction of p-aminopropiophenone excreted as N-hydroxy derivative is the same over a wide range of doses. The relationship between the concentration of N-hydroxy derivative, and nitroso analogue, in the blood and urine of rabbits is quite different from that observed in dogs.

Sprague Dawley大鼠通过灌胃给予单次5 mg PAPP/kg体重的剂量。大鼠尿液中包含三种主要成分,未改变的PAPP(10%)、N-乙酰-p-氨基苯甲酸(60%)以及一种未识别的极性化合物,作者认为这是N-乙酰-p-氨基苯甲酸的硫酸盐结合物(它可能是葡萄糖醛酸结合物)。4-N羟基氨基丙酰苯(PHAPP)通常被认为是直接产生高铁血红蛋白的物质,但这一物质或其降解产物并未被发现。
Sprague Dawley rats /were administered a single/ 5 mg PAPP/kg bw /dose/ by gavage. Rat urine contained three major components, unchanged PAPP (10%), N-acetyl-p-aminobenzoic acid (60%) and an unidentified polar compound which the authors concluded was the sulphate conjugate of N-acetyl-p-aminobenzoic acid (it could be the glucuronic acid conjugate). 4-N hydroxyl amino propiophenone (PHAPP) is generally believed to the proximate methaemoglobin generator, but this or degradation products of it were not found.

四只比格犬被给予0.5毫克/千克体重的PAPP进行排泄研究。四只动物各给予1毫克/千克体重进行代谢研究。PAPP主要通过尿液快速排泄。未观察到N-乙酰衍生物,放射性物质存在于未改变的PAPP、4-氨基-3-羟基苯丙酮以及β-羟基化衍生物中,均以硫酸盐结合物形式存在。
Four beagle dogs /were administered / 0.5 mg PAPP/kg bw ... for excretion studies. One mg/kg bw to four animals for metabolism studies. Excretion was rapid primarily in the urine.

代谢
猴子体内的代谢途径比大鼠或狗更为复杂。虽然与大鼠相同的主体途径存在,但一些对氨基苯甲酸会以N-乙酰-p-氨基酚的形式出现。PAPP也会被代谢为对氨基苯甲酸,然后与甘氨酸结合形成对氨基马尿酸。对猴子血浆的甲醇提取物进行分析显示,有5%的放射性可归因于4,4'-二丙酰氧偶氮苯(DAPB)/在给予25毫克PAPP/千克体重(14)C标记后/,这可能是由于PHAPP[建议的亚铁血红素形成代谢物]所致。
The metabolic pathway in the monkeys was more complex than either the rat or dog. The same major pathway as rats occurs, but some of the p aminobenzoic acid appears as N-acetyl-p-aminophenol. PAPP is also metabolized to p-amino benzoic acid with is then conjugated with glycine to give para-aminohippuric acid. Analysis of methanol extract of monkey plasma showed 5% of the radioactivity was attributable to 4,4'-dipropionylazooxybenene (DAPB) /following 25 mg PAPP/kg bw (14)C-labeled)/, which could have resulted from PHAPP [the suggested methemoglobin forming metabolite].

氰化物解毒剂亚铁血红蛋白前体4-氨基苯丙酮(4-PAPP)的生物活化研究使用了大鼠和人类的微体。在大鼠肝脏和NADPH的单室和双室系统中,达普松和苯佐卡因比4-PAPP更有效地生成亚铁血红蛋白。在单室研究中,抑制4-PAPP介导的亚铁血红蛋白形成的效力顺序是西咪替丁(1.5 mM)>异烟肼(500 uM)/二乙基二硫代氨基甲酸(DDC,1 mM)>红霉素(500 uM)。在双室系统中,人类肝脏微体激活4-PAPP的过程被DDC和西咪替丁部分抑制。这些初步研究表明,4-PAPP可能在大鼠中通过细胞色素P450 2C11、2E1和3A代谢,在人类中可能通过细胞色素P450 2C、2E1和可能的3A4代谢。
The bioactivation of the cyanide antidote methemoglobin former 4-aminopropiophenone (4-PAPP) was studied using rat and human microsomes. With rat liver and NADPH in single and two-compartment systems, dapsone and benzocaine were more potent methemoglobin generators compared with 4-PAPP. In the single compartment studies, the order of potency of inhibition of 4-PAPP-mediated methemoglobin formation was cimetidine (1.5 mM)>isoniazid (500 uM)/diethyldithiocarbamate (DDC, 1 mM)>erythromycin (500 uM). Human liver microsomal activation of 4-PAPP in the two-compartment system was partially inhibited by both DDC and cimetidine. These preliminary studies suggest that 4-PAPP may be metabolized by /cytochromes P450/ 2C11, 2E1 and 3A in the rat and /cytochromes P450/ 2C, 2E1 and probably 3A4 in man.

硝基苯、苯胺、对氨基甲苯(p-AT)、对氨基苯乙酮(p-AAP)和对氨基丙酮(p-APP)在小鼠中作为高铁血红蛋白形成剂具有广泛不同的活性。通过腹膜内给药后的循环水平评估,p-AT是这一系列化合物中活性最弱的,但硝基苯和苯胺即使在致死剂量下也仅表现出较弱的活性。上述系列中的三个羟基胺类似物在小鼠中作为高铁血红蛋白形成剂的活性大致相当。此外,在0.1摩尔/千克的剂量下,每种化合物都产生了短暂的methemoglobinemia,与p-APP引起的现象非常相似。邻氨基酚也产生了具有相似时间特征的高铁血红蛋白血症,但这个化合物的活性大约低十倍。对氨基酚的活性更弱,大约与苯胺相当。当苯胺或硝基苯与亚硝酸钠联合给药时,循环中的高铁血红蛋白水平得以延长。然而,当它们与p-APP联合给药时,并未观察到这种协同作用。亚甲基蓝在体内减弱了对p-APP和亚硝酸盐的高铁血红蛋白反应。然而,在产生等效峰值循环水平的剂量下,它对后者更有效。在时间模式上,亚硝酸盐在体内(完整小鼠)和体外(小鼠红细胞悬浮液)的效果相似。相比之下,由苯基羟基胺引起的高铁血红蛋白血症在红细胞中的持续时间似乎比在完整动物中长。显然,红细胞外的因素在终止某些诱导型高铁血红蛋白血症中起着重要作用。
Nitrobenzene, aniline, p-aminotoluene (p-AT), p-aminoacetophenone (p-AAP) and p-aminopropiophenone (p-APP) have widely different activities as methemoglobin-forming agents in mice. As assessed by circulating levels after intra-peritoneal administration, p-AT was the least potent compound of the series, but nitrobenzene and aniline were also only weakly active even at lethal doses. Three hydroxylamine analogues from the above series were all about equipotent as methemoglobin forming agents in mice. Moreover, at a dose of 0.1 mole/kg each produced a transient methemoglobinemia that was remarkably similar to that resulting from p-APP. A methemoglobinemia with similar temporal characteristics was also produced by o-aminophenol, but this compound is about ten times less potent. p-Aminophenol was even weaker, being about as active as aniline. When aniline or nitrobenzene was given in combination with sodium nitrite, circulating methemoglobin levels were prolonged. Such a synergism was not seen when either was given in combination with p-APP. Methylene blue in vivo attenuated the methemoglobinemic response to both p-APP and nitrite. It was more effective, however, against the latter, as evaluated at doses that produced equivalent peak circulating levels. In its time pattern the effect of nitrite was similar in vivo (intact mouse) and in vitro (mouse red cell suspension). In contrast, methemoglobinemia produced by phenylhydroxylamine appears to persist longer in red cells than in the intact animal. Apparently, factors external to the red cell are important in terminating some kinds of induced methemoglobinemias.

预先用亚硝酸钠或对-氨基苯丙酮处理已被证明可以保护犰狳、兔子和老鼠免受静脉注射硫化钠导致的死亡。保护程度与预期的变性血红蛋白血症水平相关。用亚硝酸盐或PAPP预先处理小鼠,在连续暴露于三种不同浓度的硫化氢蒸气中时,显著延长了它们的存活时间,但在中间浓度下获得了最大的保护效果。在某些条件下,丙二醇也通过一种非特异性的作用,可能是通过抑制呼吸,延长了存活时间。本文讨论了变性血红蛋白血症对硫化物的保护机制,以及硫化变性血红蛋白的形成及其在体内的可能命运。
Pretreatment with sodium nitrite or p-aminopropiophenone has been shown to protect armadillos, rabbits, and mice from death by parenteral sodium sulfide. The degree of protection correlated with anticipated levels of methemoglobinemia. Pretreatment of mice with nitrite or PAPP significantly prolonged their survival during continuous vapor exposure to any one of three concentrations of hydrogen sulfide, but the greatest protection occurred at the intermediate concentration. Under certain conditions propylene glycol also prolonged survival time, probably by a nonspecific action in depressing respirations. The mechanism of protection against sulfide by methemoglobinemia is discussed with reference to the formation of sulfmethemoglobin and its possible fate in vivo.

吸收、分配和排泄
Sprague Dawley 大鼠通过灌胃接受了一次性的 5 毫克 PAPP/千克体重的剂量。大鼠的排泄速度很快,主要在尿液中,但也有 9% 在粪便中,以及一小部分放射性标记(4-6%)在呼出的空气中被发现。[作者声称这仅适用于雄性,这个结论是有缺陷的。这个估计是基于放射性标记研究的。对于雄性大鼠,标签位于羰基原子上,而对于雌性大鼠,标签位于苯环上。很可能呼出的标签来自代谢为 CO2,这在研究中只会出现在雄性大鼠中。]
Sprague Dawley rats /were administered a single/ 5 mg PAPP/kg bw /dose/ by gavage. Rat excretion was rapid primarily in the urine, but 9% in feces, and a small proportion of a radio label 4-6% was found in expired air. [The authors claim this only applies in males, this conclusion is flawed. The estimate is based on radiolabel studies. The label was on the carbonyl atom for the male rats but on the benzene ring for the females. It is likely that the exhaled label was from metabolism to CO2, which would only be seen in the males in the study.]

吸收、分配和排泄
PAPP从0.4 mg/kg bw/day灌胃剂量的生物利用度为32 +/- 10%(生物利用度取决于配方,范围为20 - 47%),达到最高高铁血红蛋白浓度的时间为60 - 90分钟。报告指出,高铁血红蛋白的峰值滞后于血浆药物浓度峰值至少60分钟。这份报告提出PAPP被细胞色素P450(可能是在肺部)氧化,然后进入血液,其中一些活性代谢物氧化血红蛋白。这项研究表明,通过口服途径吸收相对较高且迅速……达到高铁血红蛋白浓度峰值前的时间较短(对于PAPP大约为90分钟),这表明该物质容易被代谢和排泄,这与分子的结构相符(猫除外)。
The bioavailability of the PAPP from /a/ 0.4 mg/kg bw/day gavage dose was 32 +/- 10% (the bioavailability depended on the formulation, the range being 20 - 47%), and the time to the maximum methemoglobin concentration was 60 - 90 minutes. The peak methemoglobin was stated to lagged behind the peak plasma drug concentration by at least 60 minutes. This report proposes that PAPP is oxidized by cytochrome P450 (possibly in the lung) and then enters the blood where some of active metabolite oxidizes hemoglobin. This study demonstrates relatively high and rapid absorption via the oral route ... The short period time before the peak methemoglobin concentration (about 90 minutes for PAPP) indicates that the substance is readily metabolized and excreted, as would be expected from the structure of the molecule (with the possible exception of cats).

    (±)-2-(N-tert-Butylamino)-3′-[125I]-iodo-4′-azidopropiophenone: A dopamine transporter and nicotinic acetylcholine receptor photoaffinity ligand based on bupropion (Wellbutrin, Zyban)
    摘要:
    Towards addressing the knowledge gap of how bupropion interacts with the dopamine transporter (DAT) and nicotinic acetylcholine receptors (nAChRs), a ligand was synthesized in which the chlorine of bupropion was isosterically replaced with an iodine and a photoreactive azide was added to the 4'-position of the aromatic ring. Analog (+/-)-3 (SADU-3-72) demonstrated modest DAT and alpha 4 beta 2 nAChR affinity. A radioiodinated version was shown to bind covalently to hDAT expressed in cultured cells and affinity-purified, lipid-reincorporated human alpha 4 beta 2 neuronal nAChRs. Co-incubation of (+/-)-[I-125]-3 with non-radioactive (+/-)-bupropion or (-)-cocaine blocked labeling of these proteins. Compound (+/-)-[I-125]-3 represents the first successful example of a DAT and nAChR photoaffinity ligand based on the bupropion scaffold. Such ligands are expected to assist in mapping bupropion-binding pockets within plasma membrane monoamine transporters and ligand-gated nAChR ion channels. (C) 2011 Elsevier Ltd. All rights reserved.

    report that Zn[N(SiMe(3))(2)](2) is a mild ammonia equivalent and base for the palladium-catalyzed amination of aryl halides and triflates. In contrast to LiN(SiMe(3))(2), the combination of Zn[N(SiMe(3))(2)](2) and LiCl coupled with aryl halides and triflates containing base-sensitive functionality in high yields. In addition, aryl bromides coupled with aryl and alkylamines with the combination of

    A novel highly selective Ag-catalyzed intermolecular amination of fluoroarenes has been developed. This transformation starts from readily available 4-carbonyl fluorobenzene and NaN3 or other nitrogen-source, via amination followed by C–F bond cleavage, thus affording the desired 4-carbonyl arylamine products under mild conditions. The reaction is accelerated using a small amount of water. This pathway

    PI3Kα/mTOR ATP-competitive inhibitors are considered as one of the promising molecularly targeted cancer therapeutics. Based on lead compound A from the literature, two similar series of 2-substituted-4-morpholino-pyrido[3,2-d]pyrimidine and pyrido[2,3-d]pyrimidine analogs were designed and synthesized as PI3Kα/mTOR dual inhibitors. Interestingly, most of the series gave excellent inhibition for both
