  Co-pigmentation and flavonoid glycosyltransferases in blue Veronica persica flowers

  摘要：

  Glycosylation is one of the key modification steps for plants to produce a broad spectrum of flavonoids with various structures and colors. A survey of flavonoids in the blue flowers of Veronica persica Poiret (Lamiales, Scrophulariaceae), which is native of Eurasia and now widespread worldwide, led to the identification of highly glycosylated flavonoids, namely delphinidin 3-O-(2-O-(6-O-p-coumaroyl-glucosyl)-6-O-p-coumaroyl-glucoside)-5-O-glucoside (1) and apigenin 7-O-(2-O-glucuronosyl)-glucuronide (2), as two of its main flavonoids. Interestingly, the latter flavone glucuronide (2) caused a bathochromic shift on the anthocyanin (1) toward a blue hue in a dose-dependent manner, showing an intermolecular co-pigment effect. In order to understand the molecular basis for the biosynthesis of this glucuronide, we isolated a cDNA encoding a UDP-dependent glycosyltransferase (UGT88D8), based on the structural similarity to flavonoid 7-O-glucuronosyltransferases (F7GAT) from Lamiales plants. Enzyme assays showed that the recombinant UGT88D8 protein catalyzes the 7-O-glucuronosylation of apigenin and its related flavonoids with preference to UDP-glucuronic acid as a sugar donor. Furthermore, we identified and functionally characterized a cDNA encoding another UGT, UGT94F1, as the anthocyanin 3-O-glucoside2 ''-O-glucosyltransferase (A3Glc2 '' GlcT), according to the structural similarity to sugar-sugar glycosyl-transferases classified to the cluster IV of flavonoid UGTs. Preferential expression of UGT88D8 and UGT94F1 genes in the petals supports the idea that these UGTs play an important role in the biosynthesis of key flavonoids responsible for the development of the blue color of V. persica flowers.

  A methoxyflavonoid, chrysoeriol, selectively inhibits the formation of a carcinogenic estrogen metabolite in MCF-7 breast cancer cells

  摘要：

  A 17 beta-estradiol (E-2) is hydrolyzed to 2-hydroxy-E-2 (2-OHE2) and 4-hydroxy-E-2 (4-OHE2 ) via cytochrome P450 (CYP) 1A1 and 1B1, respectively. In estrogen target tissues including the mammary gland, ovaries, and uterus, CYP1B1 is highly expressed, and 4-OHE2 is predominantly formed in cancerous tissues. In this study, we investigated the inhibitory effects of chrysoeriol (luteorin-3'-methoxy ether), which is a natural methoxyflavonoid, against activity of CYP1A1 and 1B1 using in vitro and cultured cell techniques. Chrysoeriol selectively inhibited human recombinant CYP1B1-mediated 7-ethoxyresorufin-O-deethylation (EROD) activity 5-fold more than that of CYP1A1-mediated activity in a competitive manner. Additionally, chrysoeriol inhibited E-2 hydroxylation was catalyzed by CYP1B1, but not by CYP1A1. Methylation of 4-OHE2, which is thought to be a detoxification process, was not affected by the presence of chrysoeriol. In human breast cancer MCF-7 cells, chrysoeriol did not affect the gene expression of CYP1A1 and 1B1, but significantly inhibited the formation of 4-methoxy E-2 without any effects on the formation of 2-methoxy E-2. In conclusion, we present the first report to show that chrysoeriol is a chemopreventive natural ingredient that can selectively inhibit CYP1B1 activity and prevent the formation of carcinogenic 4-OHE2 from E-2.

  chemical synthesis, to perform SAR analysis of velutin structural analogues. The SAR study revealed that the substitution of functional groups at C5, C7, C3′, and C4′ of the flavone backbone affects biological activities related to melanin synthesis. The coexistence of hydroxyl and methoxy at the C5 and C7 position is essential for inhibiting tyrosinase activity. However, 1,2-diol compounds substituted

  Velutin是天然植物中的一种黄酮，具有多种有益的活性，例如美白皮肤，以及抗炎，抗过敏，抗氧化和抗菌活性。但是，尚未研究velutin的结构与其抗黑素生成活性之间的关系。在这项研究中，我们通过化学合成获得了12种维他汀衍生物，这些化合物在黄酮骨架的C5，C7，C3'和C4'处被氢，羟基和甲氧基官能团取代，以进行维他汀结构类似物的SAR分析。SAR研究表明，黄酮骨架的C5，C7，C3'和C4'处的官能团取代会影响与黑色素合成有关的生物学活性。羟基和甲氧基在C5和C7位置的共存对于抑制酪氨酸酶活性至关重要。然而，在黄酮骨架的C3'和C4'处取代的1,2-二醇化合物诱导黑素瘤细胞凋亡。此外，在C3'和C4'处被甲氧基或氢取代对于抑制黑色素生成是必不可少的。因此，这项研究将有助于开发天然来源的功能材料，以调节黑色素的合成。
• Accurate Prediction of Glucuronidation of Structurally Diverse Phenolics by Human UGT1A9 Using Combined Experimental and In Silico Approaches

  日期：2012.6

  Catalytic selectivity of human UGT1A9, an important membrane-bound enzyme catalyzing glucuronidation of xenobiotics, was determined experimentally using 145 phenolics and analyzed by 3D-QSAR methods. Catalytic efficiency of UGT1A9 was determined by kinetic profiling. Quantitative structure activity relationships were analyzed using CoMFA and CoMSIA techniques. Molecular alignment of substrate structures was made by superimposing the glucuronidation site and its adjacent aromatic ring to achieve maximal steric overlap. For a substrate with multiple active glucuronidation sites, each site was considered a separate substrate. 3D-QSAR analyses produced statistically reliable models with good predictive power (CoMFA: q2 = 0.548, r2 = 0.949, r pred 2  = 0.775; CoMSIA: q2 = 0.579, r2 = 0.876, r pred 2  = 0.700). Contour coefficient maps were applied to elucidate structural features among substrates that are responsible for selectivity differences. Contour coefficient maps were overlaid in the catalytic pocket of a homology model of UGT1A9, enabling identification of the UGT1A9 catalytic pocket with a high degree of confidence. CoMFA/CoMSIA models can predict substrate selectivity and in vitro clearance of UGT1A9. Our findings also provide a possible molecular basis for understanding UGT1A9 functions and substrate selectivity.

  通过实验使用145种酚类化合物，并通过3D-QSAR方法分析，确定了人UGT1A9的催化选择性。UGT1A9是一种重要的膜结合酶，催化外源性物质的葡糖醛酸化反应。通过动力学分析确定了UGT1A9的催化效率。使用CoMFA和CoMSIA技术分析了定量结构活性关系。通过将葡糖醛酸化位点及其相邻的芳香环重叠，实现了底物结构的最大立体重叠。对于具有多个活性葡糖醛酸化位点的底物，每个位点被视为单独的底物。3D-QSAR分析产生了统计上可靠的模型，具有良好的预测能力（CoMFA：q2=0.548，r2=0.949，r pred 2=0.775；CoMSIA：q2=0.579，r2=0.876，r pred 2=0.700）。通过轮廓系数图阐明了底物中负责选择性差异的结构特征。将轮廓系数图叠加在UGT1A9的同源模型的催化口袋中，能够高度自信地识别UGT1A9的催化口袋。CoMFA/CoMSIA模型可以预测底物的选择性和UGT1A9的体外清除率。我们的发现还提供了理解UGT1A9功能和底物选择性的可能分子基础。

The latter, hitherto unreported enzyme, catalysed the formation of 3-O-methyl ethers of galangin and quercetin. The stepwise O-methylation of a number of compounds, especially quercetin and quercetagetin, tends to suggest a coordinated sequence of O-methylations on the surface

  essential for the antidiabetic activity of flavonoids, we synthesized two series of flavonoids, 5,7‐dihydroxyflavanones and 5,7‐dihydroxyflavones. In a screening for potential antidiabetic activity, most of the flavonoids showed a remarkable in vitro activity, and compounds 1f, 2d, and 3c were significantly more effective than the positive control, metformin.
