    A substituent group of a suitable size and the trimethoxybenzene had a certain influence on the bioactivity of the flavonoid salicylate derivatives. Compound 2 and its salicylate derivatives 7a–7g containing the trimethoxybenzene exhibited more antiproliferative activity. Among them, compound 7g displayed the most potent antiproliferative activity against MGC-803 cells and MFC cells with the concentration

  • Accurate Prediction of Glucuronidation of Structurally Diverse Phenolics by Human UGT1A9 Using Combined Experimental and In Silico Approaches
    作者:Baojian Wu、Xiaoqiang Wang、Shuxing Zhang、Ming Hu
    DOI:10.1007/s11095-012-0666-z
    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。

    作者:Hong Gao、Jun Nishida、Shizuka Saito、Jun Kawabata
    DOI:10.3390/12010086
    日期:——
    Baicalein (1), 6-hydroxyapigenin (6), 6-hydroxygalangin (13) and 6-hydroxy-kaempferol (14), which are naturally occurring flavonoids from a set of 14 hydroxy-flavones tested, exhibited high inhibitory effects on tyrosinase with respect to L-DOPA,while each of the 5,6,7-trihydroxyflavones 1, 6, 13 or 14 acted as a cofactor tomonophenolase. Moreover, 6-hydroxykaempferol (14) showed the highest activity andwas a competitive inhibitor of tyrosinase compared to L-DOPA. 5,6,7-Trihydroxyflavones 1, 6, 13 or 14 showed also high antioxidant activities. Hence, weconclude that the 5,6,7-trihydroxy-flavones are useful as good depigmentation agentswith inhibitory effects in addition to their antioxidant properties.
    从一组14种羟基黄酮中,天然存在的黄酮类化合物Baicalein(1)、6-羟基芹菜素(6)、6-羟基高良姜素(13)和6-羟基山柰酚(14)对酪氨酸酶关于L-多巴显示出高抑制效果,其中每一种5,6,7-三羟基黄酮1、6、13或14作为单酚酶的辅因子。此外,6-羟基山柰酚(14)表现出最高的活性,并且与L-多巴相比是酪氨酸酶的竞争性抑制剂。5,6,7-三羟基黄酮1、6、13或14也显示出高抗氧化活性。因此,我们得出结论,5,6,7-三羟基黄酮除了其抗氧化特性外,还具有良好的脱色素抑制效果,是有用的脱色素剂。
  • A New Synthesis for Acacetin, Chrysoeriol, Diosmetin, Tricin and Other Hydroxylated Flavones by Modified Baker-Venkataraman Transformation
    作者:N. Pandurangan
    DOI:10.2174/1570178611999140206115633
    日期:2014.2
    Baker-Venkataraman (BV) rearrangement is the method of choice for the synthesis of flavones. The major limitation of BV is that it requires extensive protections and deprotections of hydroxyl groups which make the process lengthy and cumbersome. In the present study, a three step efficient method has been developed using simple protecting groups and easily available starting materials. New syntheses
    Baker-Venkataraman(BV)重排是合成黄酮的选择方法。BV的主要局限性在于它需要对羟基进行广泛的保护和脱保护,这会使该过程冗长且麻烦。在本研究中,使用简单的保护基团和容易获得的原料开发了一种三步有效的方法。描述了新的合成醋氨蝶呤,瓜油酚,薯met皂素,甘油三酸酯和其他羟基黄酮。
