• 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。

  Glucuronidation is often recognized as one of the rate-determining factors that limit the bioavailability of flavonols. Hence, design and synthesis of more bioavailable flavonols would benefit from the establishment of predictive models of glucuronidation using kinetic parameters [e.g., K m, V max, intrinsic clearance (CLint) = V max/ K m] derived for flavonols. This article aims to construct position (3-OH)-specific comparative molecular field analysis (CoMFA) models to describe UDP-glucuronosyltransferase (UGT) 1A9-mediated glucuronidation of flavonols, which can be used to design poor UGT1A9 substrates. The kinetics of recombinant UGT1A9-mediated 3-O-glucuronidation of 30 flavonols was characterized, and kinetic parameters ( K m, V max, CLint) were obtained. The observed K m, V max, and CLint values of 3-O-glucuronidation ranged from 0.04 to 0.68 μM, 0.04 to 12.95 nmol/mg/min, and 0.06 to 109.60 ml/mg/min, respectively. To model UGT1A9-mediated glucuronidation, 30 flavonols were split into the training (23 compounds) and test (7 compounds) sets. These flavonols were then aligned by mapping the flavonols to specific common feature pharmacophores, which were used to construct CoMFA models of V max and CLint, respectively. The derived CoMFA models possessed good internal and external consistency and showed statistical significance and substantive predictive abilities ( V max model: q 2 = 0.738, r 2 = 0.976, r pred2 = 0.735; CLint model: q 2 = 0.561, r 2 = 0.938, rpred2 = 0.630). The contour maps derived from CoMFA modeling clearly indicate structural characteristics associated with rapid or slow 3-O-glucuronidation. In conclusion, the approach of coupling CoMFA analysis with a pharmacophore-based structural alignment is viable for constructing a predictive model for regiospecific glucuronidation rates of flavonols by UGT1A9.

  葡糖醛酸化通常被认为是限制类黄酮醇生物利用度的决定速率的因素之一。因此，利用类黄酮醇的动力学参数（如 Km、Vmax、内在清除率（CLint）= Vmax/ Km）建立葡糖醛酸化的预测模型，将有利于设计合成更多生物可利用的类黄酮醇。本文旨在构建针对3-OH位点的特定比较分子场分析（CoMFA）模型，描述UDP-葡糖醛酸基转移酶（UGT）1A9介导的类黄酮醇葡糖醛酸化过程，该模型可用于设计不佳的UGT1A9底物。我们对重组UGT1A9介导的30种类黄酮醇的3-O-葡糖醛酸化动力学进行了表征，并获得了动力学参数（Km、Vmax、CLint）。观察到的3-O-葡糖醛酸化Km、Vmax和CLint值分别在0.04至0.68 μM、0.04至12.95 nmol/mg/min和0.06至109.60 ml/mg/min之间。为了模拟UGT1A9介导的葡糖醛酸化，我们将30种类黄酮醇分为训练集（23个化合物）和测试集（7个化合物）。然后通过将类黄酮醇映射到特定的共同特征药效团来对齐，从而构建了Vmax和CLint的CoMFA模型。得到的CoMFA模型具有良好的内在和外在一致性，显示出统计学意义和实质性的预测能力（Vmax模型：q2 = 0.738，r2 = 0.976，rpred2 = 0.735；CLint模型：q2 = 0.561，r2 = 0.938，rpred2 = 0.630）。从CoMFA建模得到的轮廓图清晰地表明了与快速或慢速3-O-葡糖醛酸化相关的结构特征。总之，结合CoMFA分析和基于药效团的结构对齐方法是可行的，可以构建用于UGT1A9介导的类黄酮醇区域特异性葡糖醛酸化速率的预测模型。
