代谢
2-羟基-4-甲氧基苯甲酮(HMB)在大鼠离体肝细胞中的代谢和细胞毒性,以及HMB及其代谢物在MCF-7人类乳腺癌细胞中的拟雌激素活性,以及雌激素受体竞争性结合试验,分别进行了研究。用HMB培养肝细胞导致细胞活力浓度和时间依赖性下降,伴有细胞内ATP和腺苷酸池的丢失。在肝细胞悬浮液中低毒性水平(0.25 mM)的HMB被酶促转化为2,4-二羟基苯甲酮(DHB)和一个羟基化中间体,该中间体通过质谱联用HPLC暂时鉴定为2,2'-二羟基-4-甲氧基苯甲酮(DHMB)的同分异构体。此外,母体化合物和两个中间体迅速与葡萄糖醛酸结合,而未结合的DHMB和2,3,4-三羟基苯甲酮(THB)被鉴定为微量中间体。在另一实验中,DHB和THB以浓度依赖性方式竞争性地取代了与重组人雌激素受体α结合的17β-雌二醇:已知的拟雌激素化合物DES和BPA,以及DHB和THB的IC50分别约为1 x 10(-8),1 x 10(-5),5 x 10(-5)和5 x 10(-4) M。此外,DHB在10(-8)至10(-6) M的浓度下以浓度依赖性方式导致MCF-7细胞增殖。DHMB和THB在10(-7)和10(-6) M时也引起细胞数量轻微增加,而HMB在10(-9)至10(-4) M的浓度下对细胞增殖没有影响。根据竞争性结合的相对IC50和对MCF-7细胞增殖效应,可以得出雌激素活性的顺序为DHB>THB>DHMB。这些结果表明,一些羟基化中间体如DHB而非母体化合物通过生物转化充当了拟雌激素。
The metabolism and cytotoxicity of 2-hydroxy-4-methoxybenzophenone (HMB) in isolated rat hepatocytes and the xenoestrogenic activity of HMB and its metabolites in MCF-7 human breast cancer cells and an estrogen receptor competitive binding assay have been studied, respectively. The incubation of hepatocytes with HMB caused a concentration- and time-dependent decrease in cell viability, accompanied by loss of intracellular ATP and adenine nucleotide pools. HMB at a low-toxic level (0.25 mM) in the hepatocyte suspensions was converted enzymatically to 2,4-dihydroxybenzophenone (DHB) and a hydroxylated intermediate, which was tentatively identified as an isomer of 2,2prime prime or minute-dihydroxy-4-methoxybenzophenone (DHMB) as determined by mass spectroscopy coupled with HPLC. Furthermore, the parent compound and both intermediates were rapidly conjugated to glucuronides, whereas free unconjugated DHMB and 2,3,4-trihydroxybenzophenone (THB) were identified as trace intermediates. In another experiment, DHB and THB displaced competitively 17beta-estradiol bound to the recombinant human estrogen receptor alpha in a concentration-dependent manner: IC(50) of diethylstilbestrol and bisphenol A, which are known xenoestorogenic compounds, and DHB and THB was approximately 1 x 10(-8), 1 x 10(-5), 5 x 10(-5) and 5 x 10(-4) M, respectively. Further, DHB at concentrations from 10(-8) to 10(-6) M caused a concentration-dependent proliferation of MCF-7 cells. DHMB and THB at 10(-7) and 10(-6) M also elicited a slight increase in cell numbers, whereas HMB at concentrations from 10(-9) to 10(-4) M did not affect the cell proliferation. Based on the relative IC50 for the competitive binding and the proliferative effect on MCF-7 cells, it follows that in estrogenic potency, DHB>THB>DHMB. These results indicate that some hydroxylated intermediates such as DHB rather than the parent compound act as a xenoestrogen via biotransformation.

含有紫外线过滤剂的防晒霜推荐使用,以减少太阳紫外线辐射造成的损害。最近,苯甲酮(BP)型紫外线过滤剂已广泛用作保湿产品和防晒乳液中的紫外线稳定剂;然而,关于长期接触这些化合物的潜在有害影响的信息非常有限。因此,我们使用气相色谱-质谱(GC-MS)研究了大鼠中BP型紫外线过滤剂的毒物代谢动力学。为了研究BP型紫外线过滤剂的代谢,我们分析了母化合物BP和2-羟基-4-甲氧基苯甲酮(HMB)。在大鼠中,BP主要转化为苯甲醇(BH)和4-羟基苯甲酮(HBP)(即A型紫外线过滤剂)。相比之下,HMB转化为至少三个中间体,包括2,4-二羟基苯甲酮(DHB),它是通过邻去甲基化形成的,随后转化为2,3,4-三羟基苯甲酮(THB),以及2,2'-二羟基-4-甲氧基苯甲酮(DHMB),它是通过HMB的芳香羟基化形成的(即B型紫外线过滤剂)。接下来,BP的毒物代谢动力学曲线在BP给药后约4小时达到峰值浓度(Cmax)2.06+/-0.46微克/毫升。单次口服HMB后,HMB的Cmax在3小时内(Tmax)达到21.21+/-11.61微克/毫升,然后与BP的动力学曲线相比迅速下降。与母化合物相比,这些代谢物在大鼠血液中的浓度随时间下降得更慢。因此,我们的结果表明,从长远来看,这些代谢物可能比母化合物具有更显著的不良影响。
Sunscreens containing UV filters are recommended to reduce damage caused by solar UV radiation. Recently, benzophenone (BP)-type UV filters have become widely used as UV stabilizers in skin-moisturizing products and sunscreen lotions; however, very little information is available regarding the potential harmful effects of prolonged exposure to these compounds. Therefore, we investigated the toxicokinetics and metabolism of BP-type UV filters in rats using gas chromatography-mass spectrometry (GC-MS). To examine the metabolism of BP-type UV filters, we analyzed the parent compounds BP and 2-hydroxy-4-methoxybenzophenone (HMB). In rats, BP was mainly converted to benzhydrol (BH) and 4-hydroxybenzophenone (HBP) (i.e., type A UV filters). In contrast, HMB was converted into at least three intermediates, including 2,4-dihydroxybenzophenone (DHB), which was formed via o-demethylation and subsequently converted into 2,3,4-trihydroxybenzophenone (THB), and 2,2'-dihydroxy-4-methoxybenzophenone (DHMB), which formed via the aromatic hydroxylation of HMB (i.e., type B UV filters). Next, the toxicokinetic curve for BP showed a peak concentration (Cmax) of 2.06+/-0.46 ug/mL at approximately 4h after BP administration. After a single oral dose of HMB, the Cmax of HMB reached 21.21+/-11.61 ug/mL within 3 hr (Tmax), and then declined rapidly compared to the kinetic curve of BP. The concentration of these metabolites in rat blood decreased much more slowly over time compared to the parent compounds. Thus, our results indicate that such metabolites might have more significant adverse effects than the parent compounds over the long term.

苯并苯酮-3(2-羟基-4-甲氧基苯并苯酮,BZ-3)是一种广泛用于医药、化妆品和工业中的紫外线吸收剂,用作防晒剂和固色剂。人们通过皮肤和口服途径接触该化学物质。通过皮肤吸收的化学物质的生物利用度与通过口服途径的不同。在Sprague-Dawley大鼠经皮给药100毫克/千克体重(体重)后,研究了BZ-3的处置情况。在不同的时间间隔收集血液样本,并通过高效液相色谱法分析母体化合物及其代谢物。吸收迅速,因为在给药后5分钟内就在血浆中检测到了母体化合物及其代谢物。吸收的半衰期(t1/2)为3.45小时,对应的吸收速率常数为0.2小时^-1。在给药后2.5小时达到35 +/- 4.5微克/毫升(平均值 +/- 标准误差,S.E.)的血浆峰值浓度。从血浆中消失呈双相,具有不同的半衰期(α相为1.3小时,β相为15.05小时),血浆浓度与时间曲线下的面积为211.1 +/- 38.2微克/毫升/小时(平均值 +/- S.E.)。BZ-3及其代谢物也大量与血浆蛋白结合。在血浆中鉴定出三种代谢物,2,4-二羟基苯并苯酮(DHB)和2,2'-二羟基-4-甲氧基苯并苯酮(DHMB)是血浆中检测到的主要代谢物,而2,3,4-三羟基苯并苯酮(THB)以微量形式被检测到。组织分布研究发现THB是主要代谢物,其次是DHB(自由型和结合型)在所有检查的组织中。肝脏含量最高,其次是肾脏、脾脏和睾丸。
Benzophenone-3 (2-hydroxy-4-methoxybenzophenone, BZ-3) is a UV absorber that is used extensively in medicine, cosmetics and industry as a sunscreen and color fastener. Exposure to the chemical is through the dermal and oral route. Bioavailability of the chemical absorbed through the skin is different from that seen through the oral route. The disposition of BZ-3 was investigated after dermal administration of 100 mg/kg body weight (body wt.) in Sprague-Dawley rats. Blood samples were collected at various intervals and the parent compound and its metabolites were analyzed by HPLC. Absorption was rapid as the parent compound and its metabolites were detected in plasma 5 min post-administration. The half-life (t1/2) of absorption was 3.45 hr corresponding to an absorption rate constant of 0.2 hr-1. Peak plasma concentration of 35 +/- 4.5 ug/mL (mean +/- standard error of the mean, S.E.) was attained at 2.5 hr post-administration. Disappearance from the plasma was biphasic with different half-lives (1.3 for alpha phase and 15.05 hr for beta phase), the area under the plasma concentration versus time curve was 211.1 +/- 38.2 ug/mL/hr (mean +/- S.E). There was also extensive binding of BZ-3 and its metabolites to plasma proteins. Three metabolites were identified in plasma, 2,4-dihydroxybenzophenone (DHB) and 2,2'-dihydroxy-4-methoxybenzophenone (DHMB) were the major metabolites detected in the plasma, while 2,3,4-trihydroxybenzophenone (THB) was detected in trace amounts. Tissue distribution studies revealed that THB was the major metabolite followed by DHB (both free and conjugated) in all tissues examined. The liver contained the highest amount followed by the kidney, spleen and testes, respectively.

当苯甲酮-3(2-羟基-4-甲氧基苯甲酮;BP-3)与未经处理的大鼠肝微粒体在NADPH存在的条件下孵化时,形成了5-羟基化代谢物,2,5-二羟基-4-甲氧基苯甲酮(5-OH-BP-3),作为BP-3的主要新代谢物。之前报道的4-去甲基化代谢物,2,4-二羟基苯甲酮(2,4-diOH-BP),作为BP-3体内的主要代谢物也被检测到。然而,在体外形成的5-OH-BP-3的量与2,4-diOH-BP大致相同。SKF 525-A和酮康唑可以抑制产生5-OH-BP-3的氧化酶活性,而奎尼丁和磺胺苯唑部分抑制。产生2,4-diOH-BP的氧化酶活性可以被SKF 525-A、酮康唑和alpha-萘黄酮抑制,磺胺苯唑部分抑制。地塞米松、苯巴比妥和3-甲基胆蒽处理的大鼠肝微粒体中,产生5-OH-BP-3的氧化酶活性增强。3-甲基胆蒽和苯巴比妥处理的大鼠肝微粒体中,产生2,4-diOH-BP的活性增强。当研究重组大鼠细胞色素P450异构体催化BP-3的代谢时,5-羟基化由P450 3A2、1A1、2B1、2C6和2D1催化,而4-去甲基化由P450 2C6和1A1催化。
When benzophenone-3 (2-hydroxy-4-methoxybenzophenone; BP-3) was incubated with liver microsomes of untreated rats in the presence of NADPH, the 5-hydroxylated metabolite, 2,5-dihydroxy-4-methoxybenzophenone (5-OH-BP-3), was formed as a major novel metabolite of BP-3. The 4-desmethylated metabolite, 2,4-dihydroxybenzophenone (2,4-diOH-BP), previously reported as the major in vivo metabolite of BP-3, was also detected. However, the amount of 5-OH-BP-3 formed in vitro was about the same as that of 2,4-diOH-BP. The oxidase activity affording 5-OH-BP-3 was inhibited by SKF 525-A and ketoconazole, and partly by quinidine and sulfaphenazole. The oxidase activity affording 2,4-diOH-BP was inhibited by SKF 525-A, ketoconazole and alpha-naphthoflavone, and partly by sulfaphenazole. The oxidase activity affording 5-OH-BP-3 was enhanced in liver microsomes of dexamethasone-, phenobarbital- and 3-methylcholanthrene-treated rats. The activity affording 2,4-diOH-BP was enhanced in liver microsomes of 3-methylcholanthrene- and phenobarbital-treated rats. When examined recombinant rat cytochrome P450 isoforms catalyzing the metabolism of BP-3, 5-hydroxylation was catalyzed by P450 3A2, 1A1, 2B1, 2C6 and 2D1, while 4-desmethylation was catalyzed by P450 2C6 and 1A1.

/The study objective was/ to investigate the protective effect of 2,4-dihydroxybenzophenone (BP-1) on acute hepatotoxicity and neurotoxicity induced by cocaine in mice, and its possible mechanism. Male ICR mice were pretreated with BP-1 (100, 200, 400 mg/kg, ig, 4 d), cocaine (75 mg/kg) was injected 30 minutes after BP-1 administration on day 4.Twenty-four hours after the injection of cocaine, the serum activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were assayed by HITACHI-7170A automatic analyzer. The content of malondialdehyde (MDA) and the content of reduced glutathione (GSH) and oxidized glutathione (GSSG) were examined, and the ratio of GSH/GSSG was calculated, and histopathological analyses were also made. Male ICR mice were pretreated with BP-1(100, 200, 400 mg/kg, ig, 3 d), cocaine (20 mg/kg) was injected 30 minutes after BP-1 administration on day 3.The locomotor activity during 0-180 minutes of mice was recorded individually for each animal immediately after cocaine injection. After the administration of cocaine, compared with corresponding solvent group, the activities of ALT [(1571+/-1161) IU/L vs. (30 +/-16) IU/L, P<0.05], AST [(408 +/- 226) IU/L vs. (101 +/- 12) IU/L, P<0.05] and LDH [(3963 +/- 1431) IU/L vs. (1935 +/- 287) IU/L, P<0.05] were significantly increased; the ratio of GSH/GSSG [(5.11 +/- 0.63) vs. (6.88 +/- 1.13),P<0.05] was decreased and the content of MDA [(1.97 +/- 1.36) umol/g vs. (0.07 +/- 0.06) umol/g, P<0.01] was significantly increased. With the pretreatment of BP-1, compared with cocaine treatment group, the serum ALT [(112 +/- 96 )IU/L, (54 +/- 20) IU/L, (35 +/- 15) IU/L, P<0.05],AST [(130 +/- 33) IU/L,(107 +/- 5) IU/L, (99 +/- 9) IU/L, P<0.05] and LDH [(1 667 +/- 564) IU/L, (1 507 +/- 365) IU/L, (1 249 +/- 349) IU/L, P<0.01] were significantly decreased, the ratios of GSH/GSSG [(7.33 +/- 1.84), (9.28 +/- 0.67), (10.5 +/- 1.20), P<0.05] were increased and the contents of MDA [(1.82 +/- 1.19) umol/g, (0.49 +/- 0.31) umol/g, (0.35 +/- 0.30) umol/g, P<0.05] were decreased. Significant amelioration in liver histopathology was also presented in the BP-1 treatment groups. The BP-1 pretreated mice showed significant reduction in activity counts evoked by cocaine (20 mg/kg), and shorten the time for activity counts to become normal. BP-1 has protective effect on acute hepatotoxicity and neurotoxicity of mice induced by cocaine. Its mechanisms might be associated with its antioxidant activity.

该研究的目的是研究2,4-二羟基苯甲酮(BP-1),一种用作紫外线吸收剂的苯甲酮衍生物,对C57BL/6J小鼠对乙酰氨基酚(APAP)诱导的肝毒性的影响。小鼠每天早晨分别以200、400和800毫克/千克体重的剂量口服BP-1,持续4天,然后在皮下给予肝毒性剂量的APAP(350毫克/千克体重)。在APAP中毒后24小时,测量血清酶,包括血清丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、乳酸脱氢酶(LDH),并检查肝脏组织病理学变化。BP-1给药显著降低了血清ALT、AST和LDH水平。肝脏组织病理学检查显示,BP-1给药以剂量依赖性方式拮抗了APAP诱导的肝脏病理损伤。进一步的测试表明,BP-1预处理显著减少了APAP诱导的肝脂质过氧化,并明显改善了谷胱甘肽的耗竭。BP-1可以有效保护C57BL/6J小鼠免受APAP诱导的肝毒性,减少氧化应激可能是保护机制的一部分。
/The study objective was/ to examine the effects of 2,4-dihydroxybenzophenone (BP-1), a benzophenone derivative used as an ultraviolet light absorbent, on acetaminophen (APAP)-induced hepatotoxicity in C57BL/6J mice. Mice were administered orally with BP-1 at doses of 200, 400 and 800 mg/kg body weight respectively every morning for 4 d before a hepatotoxic dose of APAP (350 mg/kg body weight) was given subcutaneously. Twenty four hours after APAP intoxication, the serum enzyme including serum alaine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) were measured and liver histopathologic changes were examined. BP-1 administration dramatically reduced serum ALT, AST and LDH levels. Liver histopathological examination showed that BP-1 administration antagonized APAP-induced liver pathological damage in a dose-dependent manner. Further tests showed that APAP-induced hepatic lipid peroxidation was reduced significantly by BP-1 pretreatment, and glutathione depletion was ameliorated obviously. BP-1 can effectively protect C57BL/6J mice from APAP-induced hepatotoxicity, and reduction of oxidative stress might be part of the protection mechanism.

苯并苯酮-3【2-羟基-4-甲氧基苯并苯酮(HMB),氧苯酮,Spectra-Sorb UV-9光吸收剂】被广泛应用于许多化妆品和防晒霜中作为紫外线吸收剂。本研究旨在调查HMB(按100毫克/千克体重口服给药)的代谢情况。通过高效液相色谱分析,识别出2,4-二羟基苯并苯酮(DHB)、2,2'-二羟基-4-甲氧基苯并苯酮(DHMB)和2,3,4-三羟基苯并苯酮(THB)作为自由和结合形式的代谢物。HMB在给药后5分钟内被迅速吸收、代谢,并在血浆中(作为自由和蛋白结合形式)检测到。母化合物及其代谢物(自由和结合形式)在给药后6小时内在大多数组织中检测到。DHB在大多数组织中都有存在,在肝脏中浓度最高。DHMB仅在肝脏、脾脏和心脏中以结合形式检测到。在生物样本中也检测到微量的THB。尿液是HMB及其代谢物消除的主要途径,而粪便则是次要途径。本研究揭示了HMB代谢的主要途径为O-脱烷基化。
Benzophenone-3 [2-hydroxy-4-methoxybenzophenone (HMB), oxybenzone, Spectra-Sorb UV-9 light absorber] is used in many cosmetics and sunscreens as a UV absorber. This study was conducted to investigate the metabolism of HMB (100 mg/kg body weight administered orally). 2,4-Dihydroxybenzophenone (DHB), 2,2'-dihydroxy-4-methoxybenzophenone (DHMB), and 2,3,4-trihydroxy-benzophenone (THB) metabolites were identified as free and conjugated forms by HPLC analysis. HMB was rapidly absorbed, metabolized, and detected in plasma (as free and protein bound) at 5 min postadministration. The parent compound and metabolites (free and conjugated) were detected at 6 hr in most tissues. DHB was present in most tissues with the highest concentration in the liver. DHMB was only detected as the conjugated form in liver, spleen, and heart. Trace amounts of THB were also detected in biological samples. Urine was the primary route, whereas feces was the secondary route of elimination of HMB and its metabolites. This study revealed O-dealkylation as the major pathway of HMB metabolism.

苯并苯酮-3(2-羟基-4-甲氧基苯并苯酮,BZ-3)是一种广泛用于医药、化妆品和工业中的紫外线吸收剂,用作防晒剂和固色剂。人们通过皮肤和口服途径接触该化学物质。通过皮肤吸收的化学物质的生物利用度与通过口服途径的不同。在Sprague-Dawley大鼠经皮给药100毫克/千克体重(体重)后,研究了BZ-3的处置情况。在不同的时间间隔收集血液样本,并通过高效液相色谱法分析母体化合物及其代谢物。吸收迅速,因为在给药后5分钟内就在血浆中检测到了母体化合物及其代谢物。吸收的半衰期(t1/2)为3.45小时,对应的吸收速率常数为0.2小时^-1。在给药后2.5小时达到35 +/- 4.5微克/毫升(平均值 +/- 标准误差,S.E.)的血浆峰值浓度。从血浆中消失呈双相,具有不同的半衰期(α相为1.3小时,β相为15.05小时),血浆浓度-时间曲线下的面积为211.1 +/- 38.2微克/毫升/小时(平均值 +/- S.E.)。BZ-3及其代谢物也大量与血浆蛋白结合。在血浆中鉴定出三种代谢物,2,4-二羟基苯并苯酮(DHB)和2,2'-二羟基-4-甲氧基苯并苯酮(DHMB)是血浆中检测到的主要代谢物,而2,3,4-三羟基苯并苯酮(THB)仅以微量检测到。组织分布研究表明,THB是主要代谢物,其次是DHB(自由型和结合型)在所有检查的组织中。肝脏含量最高,其次是肾脏、脾脏和睾丸。
Benzophenone-3 (2-hydroxy-4-methoxybenzophenone, BZ-3) is a UV absorber that is used extensively in medicine, cosmetics and industry as a sunscreen and color fastener. Exposure to the chemical is through the dermal and oral route. Bioavailability of the chemical absorbed through the skin is different from that seen through the oral route. The disposition of BZ-3 was investigated after dermal administration of 100 mg/kg body weight (body wt.) in Sprague-Dawley rats. Blood samples were collected at various intervals and the parent compound and its metabolites were analyzed by HPLC. Absorption was rapid as the parent compound and its metabolites were detected in plasma 5 min post-administration. The half-life (t1/2) of absorption was 3.45 hr corresponding to an absorption rate constant of 0.2 hr-1. Peak plasma concentration of 35 +/- 4.5 ug/mL (mean +/- standard error of the mean, S.E.) was attained at 2.5 hr post-administration. Disappearance from the plasma was biphasic with different half-lives (1.3 for alpha phase and 15.05 hr for beta phase), the area under the plasma concentration versus time curve was 211.1 +/- 38.2 ug/mL/hr (mean +/- S.E). There was also extensive binding of BZ-3 and its metabolites to plasma proteins. Three metabolites were identified in plasma, 2,4-dihydroxybenzophenone (DHB) and 2,2'-dihydroxy-4-methoxybenzophenone (DHMB) were the major metabolites detected in the plasma, while 2,3,4-trihydroxybenzophenone (THB) was detected in trace amounts. Tissue distribution studies revealed that THB was the major metabolite followed by DHB (both free and conjugated) in all tissues examined. The liver contained the highest amount followed by the kidney, spleen and testes, respectively.

    摘要:
    由于芳基碳氢键的相对惰性、酚类产物的较高反应性导致过度氧化的副产物以及经常不足的区域选择性,芳烃的可持续、非定向和选择性催化羟基化仍然是一项持续的研究挑战。我们报告说,铁由受生物启发的l-胱氨酸衍生的配体可以催化非定向芳烃碳氢羟基化,过氧化氢作为末端氧化剂。该反应以其广泛的底物范围、出色的选择性和良好的产率而著称,并且表现出与氧化敏感官能团的相容性,如醇、多酚、醛,甚至硼酸。该方法非常适合通过多重碳氢羟基化合成多酚,以及天然产物和药物分子的后期功能化。
