葡萄糖醛酸苷基转移酶(UGT)酶催化葡萄糖醛酸化反应是人体主要的代谢和解毒途径。了解UGT识别底物的机制对于预测其对体内外源/药物处置的贡献具有重要意义。在这种兴趣的刺激下,在缺乏完整哺乳动物UGT晶体结构的情况下,建立了2D/ 3d定量结构活性关系(QSAR)和药效团模型。本文综述了模拟人类UGT底物的最新进展,包括具有多个葡萄糖醛酸化位点的底物。由于这些酶具有共同的催化机制和/或重叠的底物选择性,因此对同源酶(即植物和细菌UGT,都属于糖基转移酶(GT1) 1家族)的底物选择性(和区域选择性)有更好的了解。
The UDP-glucuronosyltransferase (UGT) enzyme catalyzes the glucuronidation reaction which is a major metabolic and detoxification pathway in humans. Understanding the mechanisms for substrate recognition by UGT assumes great importance in an attempt to predict its contribution to xenobiotic/drug disposition in vivo. Spurred on by this interest, 2D/3D-quantitative structure activity relationships (QSAR) and pharmacophore models have been established in the absence of a complete mammalian UGT crystal structure. This review discusses the recent progress in modeling human UGT substrates including those with multiple sites of glucuronidation. A better understanding of UGT active site contributing to substrate selectivity (and regioselectivity) from the homologous enzymes (i.e., plant and bacterial UGTs, all belong to family 1 of glycosyltransferase (GT1)) is also highlighted, as these enzymes share a common catalytic mechanism and/or overlapping substrate selectivity.
