  • UDP-Glycosyltransferase 3A Metabolism of Polycyclic Aromatic Hydrocarbons: Potential Importance in Aerodigestive Tract Tissues
    作者:Ana G. Vergara、Christy J.W. Watson、Gang Chen、Philip Lazarus
    DOI:10.1124/dmd.119.089284
    日期:2020.3
    Polycyclic aromatic hydrocarbons (PAHs) are potent carcinogens and are a primary risk factor for the development of lung and other aerodigestive tract cancers in smokers. The detoxification of PAHs by glucuronidation is well-characterized for the UDP-glycosyltransferase (UGT) 1A, 2A, and 2B subfamilies; however, the role of the UGT3A subfamily in PAH metabolism remains poorly understood. UGT3A enzymes are functionally distinct from other UGT subfamilies (which use UDP-glucuronic acid as a cosubstrate) due to their utilization of alternative cosubstrates (UDP- N -acetylglucosamine for UGT3A1, and UDP-glucose and UDP-xylose for UGT3A2). The goal of the present study was to characterize UGT3A glycosylation activity against PAHs and examine their expression in human aerodigestive tract tissues. In vitro metabolism assays using UGT3A2-overexpressing cell microsomes indicated that UGT3A2 exhibits glycosylation activity against all of the simple and complex PAHs tested. The V max/ K m ratios for UGT3A2 activity with UDP-xylose versus UDP-glucose as the cosubstrate ranged from 0.65 to 4.4 for all PAHs tested, demonstrating that PAH glycosylation may be occurring at rates up to 4.4-fold higher with UDP-xylose than with UDP-glucose. Limited glycosylation activity was observed against PAHs with UGT3A1-overexpressing cell microsomes. While UGT3A2 exhibited low levels of hepatic expression, it was shown by western blot analysis to be widely expressed in aerodigestive tract tissues. Conversely, UGT3A1 exhibited the highest expression in liver with lower expression in aerodigestive tract tissues. These data suggest that UGT3A2 plays an important role in the detoxification of PAHs in aerodigestive tract tissues, and that there may be cosubstrate-dependent differences in the detoxification of PAHs by UGT3A2. SIGNIFICANCE STATEMENT UGT3A2 is highly active against PAHs with either UDP-glucose or UDP-xylose as a cosubstrate. UGT3A1 exhibited low levels of activity against PAHs. UGT3A1 is highly expressed in liver while UGT3A2 is well expressed in extrahepatic tissues. UGT3A2 may be an important detoxifier of PAHs in humans.
    多环芳烃(PAHs)是强致癌物, 是吸烟者发生肺癌及口、咽等上呼吸道和上消化道癌症的首要风险因素。PAHs通过葡萄糖醛酸化反应解毒已在尿苷二磷酸葡糖基转移酶(UDP-glycosyltransferase, UGT)1A、2A和2B亚家族中得到充分阐释, 但UGT3A亚家族在PAH代谢中的作用至今仍未明了。UGT3A酶在功能上与其他亚家族截然不同, 它具有各自的供体底物:对UGT3A1而言是尿苷二磷酸N-乙酰葡糖胺, 而对于UGT3A2则是尿苷二磷酸葡萄糖与尿苷二磷酸木糖。本研究的目的是阐释UGT3A对PAHs的糖基化作用活性, 以及它在人上呼吸道和上消化道组织中的表达。通过UGT3A2过表达细胞微粒体进行的体外代谢实验表明UGT3A2对检测的所有单环和多环PAHs均有糖基化作用活性。以尿苷二磷酸木糖和尿苷二磷酸葡萄糖为供体底物的UGT3A2活性所表现出的V max/K m比率在0.65~4.4之间, 证明PAHs通过UGT3A2进行糖基化反应时, 与底物尿苷二磷酸葡萄糖相比, 底物尿苷二磷酸木糖可提速至4.4倍。UGT3A1过表达细胞微粒体表现出的对PAHs的糖基化作用活性较低。UGT3A2在肝脏中的表达水平偏低, 但通过Western blot分析可知上呼吸道和上消化道组织中的表达水平广泛。相反, UGT3A1则呈现出最高的肝表达量和较低的上呼吸道和上消化道组织表达量。这些数据表明, UGT3A2在上呼吸道和上消化道组织中对PAHs的解毒起着重要作用, 而且PAHs通过UGT3A2的解毒作用可能因供体底物的不同而存在差异。 [论著意义]UGT3A2对PAHs的活性较强, 供体底物为尿苷二磷酸葡萄糖或尿苷二磷酸木糖。UGT3A1对PAHs只表现出低水平活性。UGT3A1高度表达于肝脏, 而UGT3A2则高度表达于肝外组织。UGT3A2可能是人体内对PAHs的重要解毒酶。

    12-BP phenols and the BP 1,6-, 3,6-, 6,12-, and 9,10-quinones are now reported. The syntheses of the BP phenols (except 6-HO-BP) involve the key steps of Pd-catalyzed Suzuki−Miyaura cross-coupling of a naphthalene boronate ester with a substituted aryl bromide or triflate ester. The BP quinones were synthesized from the corresponding BP phenols by direct oxidation with the hypervalent iodine reagents
    多环芳烃(PAH)是有机物燃烧时产生的广泛环境污染物。 PAHs存在于汽车尾气和烟草烟雾中,最近被指定为人类致癌物。目前的证据表明,PAH 被酶促激活,产生与 DNA 相互作用的诱变代谢物。有证据表明存在三种激活途径:二醇环氧化物途径、自由基-阳离子途径和醌途径。这些途径对人类肺癌的相对重要性尚未确定。我们现在报道了原型 PAH 致癌物苯并[ a ]芘 (BP) 的主要苯酚和醌异构体的合成,已知或怀疑这些异构体是人支气管肺泡细胞中 BP 的代谢产物。合成方法被设计为适用于BP代谢物的13 C标记类似物的制备。这些化合物需要作为敏感 LC−MS/MS 方法的标准品,用于分析肺细胞中形成的 BP 代谢物。目前已报道了 1-、3-、6-、9- 和 12-BP 苯酚以及 BP 1,6-、3,6-、6,12- 和 9,10-醌的高效新型合成方法。 BP 苯酚(6-HO-BP 除外)的合成涉及萘硼酸酯与取代的芳基溴或三氟甲磺酸酯的
  • Modulation of Cytochrome P4501-mediated Bioactivation of Benzo[a]pyrene by Volatile Allyl Sulfides in Human Hepatoma Cells
    作者:Hyang Sook CHUN、Hyun Jung KIM、Eun Hye CHOI
    DOI:10.1271/bbb.65.2205
    日期:2001.1
    Allyl sulfides such as diallyl sulfide (DAS), diallyl disulfide (DADS), and diallyl trisulfide (DATS), typical flavor components of Allium vegetables, have been shown to inhibit benzo[a]pyrene (B[a]P)-induced carcinogenesis in animal models. As a possible mechanism of this inhibition, the effect of these volatile substances on cytochrome P450 (CYP)1 (CYP1A1, 1A2 and 1B1)-mediated bioactivation of B[a]P was investigated using a human hepatoma cell model (HepG2). DADS and DATS inhibited the B[a]P-induced ethoxyresorufin O-deethylase (EROD) activity, a marker enzyme for CYP1, by 30-90% and 70-95% at 100-1,000 μM concentration, respectively. The cell viability, an indicator of the capacity to inhibit B[a]P bioactivation, was increased by treatments of 100-1,000 μM DADS and 10-100 μM DATS. Immunoblot results indicated that the B[a]P inducible CYP1A2 protein was suppressed by 100-1,000 μM of DADS and 10-100 μM of DATS, but CYP1A1 and 1B1 were not detectable in any microsomes. Analysis of B[a]P metabolites revealed that the level of 7,8-diol formed was significantly reduced in the DADS and DATS treated microsomes as compared to the control. The level of 9,10-diol and 4,5-diol formed was also lowered by the allyl sulfide treatments. These results suggest that the protective mechanism of allyl sulfides on B[a]P-induced carcinogenesis is possibly related with the modulation of CYP1-mediated bioactivation of B[a]P.
    烯丙基硫醚,如二烯丙基硫醚(DAS)、二烯丙基二硫化物(DADS)和二烯丙基三硫化物(DATS),是薤白蔬菜的典型风味成分,在动物模型中已被证明可抑制苯并[a]芘(B[a]P)诱导的致癌作用。作为这种抑制作用的可能机制,我们使用人肝癌细胞模型(HepG2)研究了这些挥发性物质对细胞色素 P450 (CYP)1(CYP1A1、1A2 和 1B1)介导的 B[a]P 生物活化的影响。在 100-1,000 μM 浓度下,DADS 和 DATS 对 B[a]P 诱导的乙氧基瑞香素 O-脱乙基酶(EROD)活性(一种 CYP1 的标记酶)的抑制率分别为 30%-90% 和 70%-95%。细胞存活率是抑制 B[a]P 生物活化能力的指标,100-1,000 μM DADS 和 10-100 μM DATS 处理可提高细胞存活率。免疫印迹结果表明,B[a]P 诱导的 CYP1A2 蛋白受到 100-1,000 μM 的 DADS 和 10-100 μM 的 DATS 的抑制,但在任何微粒体中都检测不到 CYP1A1 和 1B1。对 B[a]P 代谢物的分析表明,与对照组相比,在 DADS 和 DATS 处理过的微粒体中形成的 7,8-二醇水平明显降低。烯丙基硫醚处理也降低了形成的 9,10-二醇和 4,5-二醇的水平。这些结果表明,烯丙基硫醚对 B[a]P 诱导的癌变的保护机制可能与调节 CYP1 介导的 B[a]P 生物活化有关。

    reagents o-iodoxybenzoic acid (IBX) and bis(trifluoro-acetoxy)iodobenzene (BTI) are shown to be general reagents for regio-controlled oxidation of polycyclic aromatic phenols (PAPs) to specific isomers (ortho, para, or remote) of polycyclic aromatic quinones (PAQs). The oxidations of a series of PAPs with IBX take place under mild conditions to furnish the corresponding ortho-PAQs. In contrast, oxidations
    高价碘试剂邻碘苯甲酸 (IBX) 和双(三氟乙酰氧基)碘苯 (BTI) 被证明是将多环芳香酚 (PAP) 区域控制氧化成特定异构体(邻、对或远程)的通用试剂。) 的多环芳香醌 (PAQ)。IBX 对一系列PAP的氧化在温和条件下发生,以提供相应的邻位PAQ。相比之下,同一系列PAP与 BTI 的氧化表现出不同的区域特异性,在结构上可行的情况下提供对位PAQ 和邻位-PAQs 或其他情况下的远程 PAQ 异构体。根据高价碘试剂的固有区域选择性以及苯酚前体的结构要求,可以预测形成的特定 PAQ 异构体的结构。IBX 和 BTI 被推荐作为 PAPs 到 PAQs 的区域控制氧化的首选试剂。
