在牛、羊、山羊、鸡、火鸡、鸭、兔和鼠的肝脏部分中测量了几种药物代谢酶活性的途径。检查的途径包括对硝基的O-去甲基化、普鲁卡因的微粒体酯解和对硝基葡萄糖苷酸化,以及细胞质中磺胺二甲嘧啶的乙酰化和2-萘酚的磺化。对于大多数测量的酶促途径,山羊与绵羊(阉割公羊)相比更类似于牛(小公牛)。例外的是UDP-葡萄糖苷转移酶活性,山羊的活性显著高于所研究任何其他物种。在鸟类亚组中,鸡和火鸡通常是相似度最高的物种。与鸡和火鸡相比,鸭的芳基硫酸转移酶同工酶III和IV的活性特别低。兔子的N-乙酰转移酶活性非常高,而绵羊和山羊的活性非常低。
Several pathways of drug metabolizing enzyme activity were measured in hepatic fractions of cattle, sheep, goats, chickens, turkeys, ducks, rabbits and rats. The pathways examined included the O-demethylation of p-nitrophenol, microsomal ester hydrolysis of procaine and glucuronidation of p-nitrophenol, and the cytosolic acetylation of sulfamethazine and sulfation of 2-naphthol. For most enzymatic pathways measured, goats were more similar to sheep (wether) than to cattle (steers). The exception was UDP-glucuronyltransferase activity, which was significantly higher for the goat than for any other species studied. Within the avian subset, the chicken and turkey were usually the most similar species. The activities of arylsulfotransferase isozymes III and IV were particularly low for the duck compared to the chicken and turkey. N-acetyltransferase activity was very high for rabbits and very low for sheep and goats.

使用模型底物,在鲶鱼和大鼠的肝部分测量了几种药物代谢酶活性途径。检查的途径包括对对硝基苯甲醚的O-去甲基化、对盐酸普鲁卡因的微粒体酯解以及对硝基葡萄糖苷酸化和对磺胺噁唑的细胞质乙酰化和对2-萘酚的磺化。鲶鱼肝制剂在25°C和37°C下孵化。在37°C下,对硝基的氧化代谢仅为大鼠的1/8,在25°C下仅为大鼠的1/12。盐酸普鲁卡因解在鲶鱼微粒体制剂中可以忽略不计。在37°C下,对硝基葡萄糖苷酸化在鲶鱼和大鼠微粒体中是等效的。鲶鱼细胞质制剂显示的N-乙酰转移酶和芳基硫酸转移酶与大鼠的几乎相当。在鲶鱼肝部分中,葡萄糖苷酸化和硫酸化的速率在37°C时高于25°C。
Several pathways of drug metabolizing enzymic activity were measured in hepatic fractions of the channel catfish and rat using model substrates. The pathways examined included the O-demethylation of p-nitroanisole, microsomal ester hydrolysis of procaine and glucuronidation of p-nitrophenol and the cytosolic acetylation of sulfamethazine and sulfation of 2-naphthol. Catfish liver preparations were incubated at both 25 °C and 37 °C. The oxidative metabolism of p-nitrophenol was only 1/8 of that of the rat at 37 °C and 1/12 that of the rat at 25 °C. Procaine ester hydrolysis was negligible in catfish microsomal preparations. At 37 °C, p-nitrophenol glucuronidation was equivalent in catfish and rat microsomes. Catfish cytosolic preparations exhibited N-acetyltransferase and arylsulfotransferase nearly comparable to those of the rat. Rates of glucuronidation and sulfation were higher at 37 °C than at 25 °C in hepatic fractions of the catfish.

为了表征各种羧酸酯酶同工酶的底物特异性,一系列含有α-或β-萘酚或对硝基作为离去基团的碳酸酯、碳酸酯、氨基甲酸酯和羧酸酯被用作人类、大鼠和小鼠肝脏微粒体酯酶的底物;还测试了大鼠肝脏微粒体中的解酶A和B。α-萘酚碳酸酯、碳酸酯和羧酸酯比相应的β-萘酚异构体被哺乳动物肝脏酯酶更快地裂解。大多数底物与解酶A相比,被解酶B以更高的速率一致性地解。与相应的羧酸酯相比,α-和β-萘酚及对硝基碳酸部分使酶的特异性活性降低了约5倍,但在碱性条件下提高了稳定性。人类和小鼠肝脏微粒体酯酶活性比解酶B的酯酶活性低5个数量级。底物结构的功能团和亲脂性影响了哺乳动物酯酶的活性。
To characterize the substrate specificities of various isozymes of carboxylesterases, a series of carbonates, thiocarbonates, carbamates, and carboxylic acid esters containing alpha- or beta-naphthol or p-nitrophenol as leaving groups were tested as substrates of human, rat and mouse liver microsomal esterases; hydrolases A and B from rat liver microsomes were also tested. The carbonates, thiocarbonates, and carboxylic esters of alpha-naphthol were cleaved more rapidly than the corresponding beta-naphthol isomers by the mammalian liver esterases. The majority of the substrates was consistently hydrolyzed at higher rates by hydrolase B compared with hydrolase A. Compared with the corresponding carboxylates, the carbonate moiety of alpha- and beta-naphthol and p-nitrophenol lowered the specific activities of the enzymes by about 5 fold but improved stability under basic conditions. Human and mouse liver microsomal esterase activities were 5 orders of magnitude lower than the esterase activities of hydrolase B. The functional group and lipophilicity of the substrate structure influenced the activity of mammalian esterases.

在大鼠肝脏中,研究了烷基胺对羟基类固醇硫酸转移酶(ST)活性的抑制作用。从WiSTar大鼠中制备了肝脏匀浆,并获得了胞浆组分。测定了针对脱氢表雄酮DHEA)、雄酮(AS)和2-萘酚(2NA)的ST活性。通过柱层析法对胞浆组分进行分级。三乙胺作为柱层析的洗脱溶剂用于纯化化学合成的3'-磷酸腺苷-5'-磷酸硫酸(PAPS),它抑制了AS和DHEA的雄激素硫酸化,但对皮质醇和2-NA的ST活性没有影响。比较了各种PAPS制剂的硫酸供体能力。检查了14种一级、二级和三级胺对DHEA皮质醇和2-NA的ST活性的抑制作用。一种二级胺,二正丁胺,和三种三级胺,三乙胺三正丙胺三正丁胺,无论性别如何,都能抑制DHEA ST活性40%至60%。然而,2-NA和皮质醇ST活性并未受到显著影响。部分纯化的羟基类固醇ST的林韦伯伯克图表明,三乙胺的抑制作用符合非竞争性抑制。这些结果提示,糖皮质激素ST与羟基类固醇ST似乎是不同的,这对于合成类固醇和作为药物给予的三级胺抑制人类肝脏ST活性具有重要意义。
The inhibition of hydroxysteroid-sulfotransferase (ST) activity in the rat liver by alkylamines was investigated. Liver homogenates were prepared from Wistar rats, and cytosolic fractions were obtained. ST activities towards dehydroepiandrosterone (DHEA), androsterone (AS), and 2-naphthol (2NA) were assayed. Cytosolic fractions were fractionated by column chromatography. Triethylamine, which was used as an elution solvent for column chromatography to purify chemically synthesized 3-phosphoadenosine-5-phosphosulfate (PAPS) inhibited androgen sulfation with AS and DHEA, but did not affect ST activities with cortisol and 2-NA. The sulfate donor ability of various PAPS preparations were compared. Fourteen primary, secondary, and tertiary amines were examined for inhibitory actions on ST activities towards DHEA, cortisol, and 2-NA. A secondary amine, di-n-butylamine, and three tertiary amines, triethylamine, tri-n-propylamine and tri-n-butylamine, inhibited DHEA ST activity by 40 to 60%, irrespective of sex. However, 2-NA and cortisol ST activities were not affected to any significant extent. Lineweaver Burk plots with partially purified hydroxysteroid ST indicated that the inhibition by triethylamine fitted a noncompetitive inhibition. The /results/ conclude that glucocorticoid ST appears to be distinct from the hydroxysteroid ST, and that this has implications for the inhibition of human liver ST activities by synthetic steroids and tertiary amines given as drugs.

毒理性
  • 毒性总结
识别和使用:2-萘酚是一种白色、叶片状或白色粉末,带有微弱的酚类气味。2-萘酚的主要用途是在染料颜料工业中,例如作为偶氮染料的偶联组分,以及制造重要的中间体,如3-羟基-2-萘甲酸(BON)及其酰胺(萘酚AS)、2-萘磺酸磺酸1-亚硝基-2-萘酚。基于2-萘酚的主要药物产品有抗真菌的托萘酯,通过与硫光气和N-甲基-间甲苯胺反应制备;半合成的青霉素萘夫西林,通过2-乙氧基制备;以及抗炎药萘普生,通过2-甲氧基制备。它还曾用作治疗脱发(斑秃)的刺激剂,也用作驱虫剂,以及治疗疥疮的消毒剂。人类暴露和毒性:广泛应用的2-萘酚软膏已导致系统性副作用,包括呕吐和死亡。摄入可能导致肾损伤、呕吐、腹泻、腹痛、晕厥、惊厥和溶血性贫血。有报道称,20名患者因为全身涂抹含有7.5% 2-萘酚的软膏50克,每天早晚各一次,连续2天治疗疥疮后,出现了眼底充血,许多人视网膜上出现了非常小的白色和色素斑点。两例中注意到了玻璃体混浊。只有一例观察到晶状体的异常,这只在晶状体后皮质上有一个点。报道称视力下降了两例,但这些病人在治疗前眼睛都不正常。动物研究:在实验中,家兔通过胃给药或涂抹皮肤给予2-萘酚,最一致的眼部变化是视网膜上出现小的白色闪亮斑点,很快就变成了色素性。随着每天继续给药,这些斑点变得更加多且大小增加。视网膜血管和虹膜通常会出现充血。房有时略显混浊,玻璃体早期通常变混浊,但随后即使继续给药也会清除。角膜和结膜从未受到影响。另一项研究报告称,在成年家兔中毒的眼睛视网膜上观察到了杆状和锥状细胞的小点状退行性变和色素上皮中色素量的不规则变化。核层和神经纤维层以及睫状上皮中出现了空泡。当给怀孕的家兔给予2-萘酚时,后代出现了先天性白内障、神经上皮的退行性变和视网膜色素细胞的肥大。进行了一项体内研究,研究了调节致白内障生物活性和解毒的关键生物化学途径的化学探针。在56或100毫克/千克的剂量平下,没有注意到2-萘酚引起的白内障或致死效应;然而,177和562毫克/千克的剂量在1.5小时内杀死了所有动物。生态毒性研究:作为测试系统,鱼胚胎和幼虫是最敏感的,幼年大头鱼和节肢动物具有中等敏感性,藻类和蜗牛对测试化合物最不敏感。
IDENTIFICATION AND USE: 2- Naphthol is a white, bulky leaflets or white powder with faint phenol-like odor. The principal uses for 2-naphthol are in the dyes and pigments industries, eg, as a coupling component for azo dyes, and to make important intermediates, such as 3-hydroxy-2-naphthalenecarboxylic acid (BON) and its anilide (naphthol AS), 2-naphtholsulfonic acids, aminonaphtholsulfonic acids, and 1-nitroso-2-naphthol. The major pharmaceutical products based on 2-naphthol are the antifungal tolnaftate, produced by reaction with thiophosgene and N-methyl-m-toluidine; the semisynthetic penicillin nafcillin, produced via 2-ethoxynaphthalene; and the anti-inflammatory naproxen, produced via 2-methoxynaphthalene. It is also was used as a counterirritant in alopecia, also as an anthelmintic, and as an antiseptic in treatment of scabies. HUMAN EXPOSURE AND TOXICITY: The extensive application of 2-naphthol ointments has been responsible for systemic side effects, including vomiting and death. Ingestion can produce renal damage, vomiting, diarrhea, abdominal pain, syncope, convulsions, and hemolytic anemia. Twenty patients who were treated for scabies by rubbing 50 g of a salve containing 7.5% 2-naphthol over the whole body morning and evening for 2 days were reported to have developed hyperemia of the fundus and many had very small white and pigmented spots in the retina. Vitreous opacities were noticed in two cases. Only in one case was abnormality of the lens observed, and this was only a dot in the posterior cortex. Visual acuity was reported to be impaired in two cases, but neither of these had normal eyes before the treatment. ANIMAL STUDIES: Experimentally in rabbits the most consistent ocular change induced by admin 2-naphthol either by stomach or by application to the skin was a development in the retina of small white shiny flecks which soon became pigmented. These became more numerous and increased in size as daily admin of the chemical continued. The retinal vessels and the iris commonly became hyperemic. The aqueous was sometimes slightly turbid, and the vitreous commonly became turbid early, but then cleared despite continuing admin of naphthol. The cornea and conjunctiva were never involved. The other study reported that in the retinas of poisoned adult rabbits spotty degeneration of the rods and cones and irregular variation in the amt of pigment in the pigment epithelium were observed. Vacuoles were present in the nuclear and nerve fiber layer and the ciliary epithelium. When 2-naphthol was administered to pregnant rabbits, the offspring had congenital cataracts, degeneration of the neuroepithelium, and hypertrophy of the retinal pigment cells. An in vivo study was conducted of the biochemical pathways modulating the cataractogenicity of naphthalene. Male mice were treated with naphthalene or its metabolites and with various chemical probes that modulate critical biochemical pathways relevant to naphthalene bioactivation and detoxification. No cataractogenic or lethal effects from 2-naphthol were noted at dose levels of 56 or 100 mg/kg; however doses of 177 and 562 mg/kg killed all the animals within 1.5 hr. ECOTOXICITY STUDIES: As test systems, fish embryos and larvae were the most sensitive, juvenile fathead minnows and arthropods had intermediate sensitivity and algae and snails were the most resistant to the test compounds.

    The O-methylation of alcohols and phenols with stoichiometric amounts of dimethyl sulfate in 1,4-dioxan or triglyme in the presence of solid potassium hydroxide and small amounts of water represents a useful method for the synthesis of methylethers in high yields and with high selectivity. The complete consumption of dimethyl sulfate in this reaction avoids the problems connected with the work-up of reaction mixtures still containing excess amounts of this toxic reagent.
