代谢
多环芳烃的K区与非K区醌都是人类胎盘NADP连接的15-羟基前列腺素脱氢酶的优秀底物。这些化合物的kcat/Km值范围从3到20 s/m。还原了甲萘醌和甲苯醌的谷胱甘肽硫醚具有相似的催化效率。此外,这些物质和某些其他谷胱甘肽硫醚是前列腺素B1氧化和多环芳烃醌还原的强效抑制剂。存在一种可能性,即多环芳烃和其他异生物质醌的潜在毒性可能通过胎盘中的氧化还原酶改变,这种酶对前列腺素来说是相对较差的底物,而胎盘组织中某些谷胱甘肽硫醚的存在可能会影响这种酶对这些醌和其他异生物质醌的还原。
Both K-region and non-K-region o-quinones of polycyclic aromatic hydrocarbons are excellent substrates for human placental NADP linked 15-hydroxyprostaglandin dehydrogenase. These compounds are reduced with kcat/Km values ranging from 3 to 20 s/m. The glutathione thioethers of menadione and toluquinone are reduced with similar catalytic efficiencies. Furthermore, these substances and certain other glutathione thioethers are potent inhibitors of prostaglandin B1 oxidation and polycyclic aromatic hydrocarbon quinone reduction. The possibility exists that the potential toxicity of quinones of polycyclic aromatic hydrocarbons and other xenobiotic substances may be altered in the placenta by an oxidoreductase for which prostaglandins are relatively poor substrates and the presence in placental tissue of certain glutathione thioethers could influence the reduction of these quinones and other xenobiotic substances by this enzyme.

  • 人类毒性摘录
/替代和体外测试/ 使用滋养层细胞系JEG-3研究菲、9,10-菲醌(PHEQ)、蒽和9,10-蒽醌单独以及与铜共同作用时的细胞毒性。终点是培养物减少alamar Blue(AB)的能力,这是能量代谢的指标,以及将羧基荧光素二醋酸乙酰氧甲基酯(CFDA AM)转化为羧基荧光素,这是膜完整性的指示。只有PHEQ引发了细胞毒性反应。PHEQ导致AB的浓度依赖性下降,但CFDA AM读数没有下降,这表明能量代谢受损。在铜的存在下,PHEQ的浓度-反应曲线向左移动,并且使用CFDA AM获得。Cu/PHEQ的协同作用归因于氧化还原循环的增加和产生的活性氧种(ROS),这会压倒抗氧化防御,首先损害能量代谢,然后是膜完整性。不透铜的螯合剂, bathocuproine,减少了PHEQ/铜的相互作用,但可渗透的螯合剂, neocuproine和铜共同作用是细胞毒性的。
/ALTERNATIVE and IN VITRO TESTS/ The trophoblast cell line, JEG-3, was used to study the cytotoxicity of phenanthrene, 9,10-phenanthrenequinone (PHEQ), anthracene, and 9,10-anthracenedione alone and with copper. The endpoints were the capacity of cultures to reduce alamar Blue (AB), a measure of energy metabolism, and to convert carboxyfluorescein diacetate acetoxymethyl ester (CFDA AM) to carboxyfluorescein, an indication of membrane integrity. Only PHEQ elicited a cytotoxic response. PHEQ caused a concentration-dependent decline in AB but not in CFDA AM readings, suggesting an impairment to energy metabolism. In the presence of copper, PHEQ concentration-response curves were shifted to the left for AB and were obtained with CFDA AM. The Cu/PHEQ synergy is attributed to an increase in redox cycling and production of reactive oxygen species (ROS), which overwhelm antioxidant defenses, damaging energy metabolism first and then membrane integrity. The impermeable copper chelator, bathocuproine, reduced the PHEQ/copper interaction, but the permeable chelator, neocuproine, and copper together were cytotoxic.

  • 人类毒性摘录
/替代实验和体外测试/ 典型的抗氧化剂N-乙酰-L-半胱氨酸(NAC)通常能保护细胞免受活性氧种(ROS)诱导的氧化损伤。9,10-菲醌(9,10-PQ),是柴油尾气颗粒中的主要醌类物质,通过NAD(P)H:醌氧化还原酶1(NQO1)进行的两电子还原在红氧循环中产生ROS,这被认为是其细胞和遗传毒性的原因。在本研究中,我们显示NAC意外地增强了低NQO1活性的细胞中9,10-PQ的毒性。在四种人皮肤细胞系中,NQO1的表达和活性低于人腺癌细胞系A549和MCF7。在皮肤细胞中,添加NAC显著增强了9,10-PQ的细胞毒性。伴随着组蛋白H2AX磷酸化的DNA双链断裂的形成也显著增加。另一方面,在腺癌细胞中,添加NAC抑制了细胞和遗传毒性。两个对比实验:在原本低表达NQO1的CHO-K1细胞中过表达NQO1,以及通过RNAi转染在腺癌细胞系A549中敲减NQO1,也显示NAC在表达高NQO1活性的细胞系中抑制了9,10-PQ诱导的毒性,而在低NQO1活性的细胞系中增强了毒性。结果表明,NAC对9,10-PQ的细胞和遗传毒性的双重作用取决于组织特定的NQO1活性。
/ALTERNATIVE and IN VITRO TESTS/ A typical antioxidant, N-acetyl-L-cysteine (NAC) generally protects cells from oxidative damage induced by reactive oxygen species (ROS). 9,10-Phenanthrenequinone (9,10-PQ), a major quinone in diesel exhaust particles, produces ROS in redox cycling following two-electron reduction by NAD(P)H:quinone oxidoreductase 1 (NQO1), which has been considered as a cause of its cyto- and genotoxicity. In this study, we show that NAC unexpectedly augments the toxicity of 9,10-PQ in cells with low NQO1 activity. In four human skin cell lines, the expression and the activity of NQO1 were lower than in human adenocarcinoma cell lines, A549 and MCF7. In the skin cells, the cytotoxicity of 9,10-PQ was significantly enhanced by addition of NAC. The formation of DNA double strand breaks accompanying phosphorylation of histone H2AX, was also remarkably augmented. On the other hand, the cyto- and genotoxicity were suppressed by addition of NAC in the adenocarcinoma cells. Two contrasting experiments: overexpression of NQO1 in CHO-K1 cells which originally expressed low NQO1 levels, and knock-down of NQO1 in the adenocarcinoma cell line A549 by transfection of RNAi, also showed that NAC suppressed 9,10-PQ-induced toxicity in cell lines expressing high NQO1 activity and enhanced it in cell lines with low NQO1 activity. The results suggested that dual effects of NAC on the cyto- and genotoxicity of 9,10-PQ were dependent on tissue-specific NQO1 activity.

制备方法与用途

菲醌简介

天然菲醌分为邻菲醌及对菲醌两种类型。丹参含有多种菲醌衍生物,其中包括丹参醌ⅡA、丹参ⅡB、隐丹参醌、丹参酸甲酯和羟基丹参醌ⅡA等为邻醌类衍生物;丹参新醌甲、丹参新配乙、丹参新醌丙则属于对菲醌类化合物。尽管丹参配类结构上具有菲醌母核,但其生源属于二帖类,显示出抗菌和扩张冠状动脉的作用。

菲醌的性质

菲醌是一种橙黄色针状结晶。熔点为208.5-210℃,沸点超过360℃,能够升华,相对密度为1.405。它不溶于水,微溶于乙醇、苯和醋酸乙酯,并能溶于乙醚和热醋酸,在浓硫酸中溶解并呈现暗绿色。通过升华可以得到橙红色片状体。

菲醌与亚硫酸钠反应生成不稳定的亚硫酸氢盐,进一步氧化可得联苯二甲酸;还原成菲氢醌。它具有显著的抑菌能力,可用作拌种剂来防止谷物黑穗病和棉花苗期病害,并作为纸浆防腐剂使用。经氢氧化钠处理后可用于制备多效能植物生长调节剂整形素。

化学性质

菲醌为橙红色针状结晶,熔点207℃,沸点360℃,可溶于乙醇、冰醋酸、苯和硫酸,不溶于水。与亚硫酸氢钠生成的加成物可溶于水,这一特性可用于提纯菲醌。

    Bent N,N′‐diphenyl‐dihydrodibenzo[a,c]phenazine amphiphiles are introduced as mechanosensitive membrane probes that operate by an unprecedented mechanism, namely, unbending in the excited state as opposed to the previously reported untwisting in the ground and twisting in the excited state. Their dual emission from bent or “closed” and planarized or “open” excited states is shown to discriminate between
    弯曲的N,N'-二苯基-二氢二苯并[a,c]吩嗪两亲物被引入作为机械敏感膜探针,其通过前所未有的机制工作,即在激发态下不弯曲,而不是之前报道的在地面中不扭曲和在室温下扭曲。兴奋状态。它们从弯曲或“闭合”和平面化或“开放”激发态的双重发射被证明可以区分水中的胶束和固序(S o )、液体无序(L d )和本体膜中的单体。双发射光谱覆盖了足够的可见光范围,以产生发出带有比例编码信息的白光的囊泡。报告了通过扩展 π 系统和助色团来改善弯曲机械载体的策略,并证明了与双光子激发荧光 (TPEF) 显微镜对巨型单层囊泡中膜域成像的兼容性。

    Durch Kondensation entsprechend substituierter 1,4-Naphtho-chinone mittels Pyridin wurden das α-Trichlor-, α, α′-Hexachlor-, α- und β-Triacetamino- sowie das β-Trimethoxy-triphthaloyl-benzol neu hergestellt.
    通过将适当取代的1,4-萘醌与吡啶缩合,新制备了α-三氯-,α,α'-六氯-,α-和β-三乙酰氨基和β-三甲氧基-三邻苯二甲酰苯。
