5-LOX inhibition is among the desired characteristics of anti-inflammatory drugs, while 15-LOX has also been considered as a drug target. Similarity in inhibition behavior between soybean LOX-1 and human 5-LOX has been observed and soybean LOX (sLOX) type 1b has been used for the evaluation of LOX inhibition in drug screening for years. After prediction of LOX inhibition by PASS and docking as well as toxicity by PROTOX and ToxPredict sixteen (E)-N-(thiazol-2-yl)-6-(4-hydroxy-6-methoxy-7-methyl-3-oxo-1,3-dihydroisobenzofuran-5-yl)-4-methylhex-4-enamide derivatives with lengths varying from about 15–20 Å were evaluated in vitro for LOX inhibitory action using the soybean lipoxygenase sLOX 1b. Docking analysis was performed using soybean LOX L-1 (1YGE), soybean LOX-3 (1JNQ), human 5-LOX (3O8Y and 3V99) and mammalian 15-LOX (1LOX) structures. Different dimensions of target center and docking boxes and a cavity prediction algorithm were used. The compounds exhibited inhibitory action between 2.5 μΜ and 165 μΜ. Substituents with an electronegative atom at two-bond proximity to position 4 of the thiazole led to enhanced activity. Docking results indicated that the LOX structures 1JNQ, 3V99 and 1LOX can effectively be used for estimation of LOX inhibition and amino acid interactions of these compounds.
抑制 5-LOX 是抗炎药物的理想特性之一,而 15-LOX 也被认为是药物靶点之一。已观察到大豆 LOX-1 与人类 5-LOX 的抑制行为具有相似性,因此大豆 LOX(sLOX)1b 型多年来一直被用于药物筛选中 LOX 抑制性的评估。在通过 PASS 和对接预测 LOX 抑制作用以及通过 PROTOX 和 ToxPredict 预测毒性之后,16 个 (E)-N-(噻唑-2-基)-6-(4-羟基-6-甲氧基-7-甲基-3-氧代-1,3-二氢异苯并呋喃-5-基)-4-甲基己-4-烯酰胺衍生物在体外使用大豆脂氧合酶 sLOX 1b 对 LOX 抑制作用进行了评估。利用大豆 LOX L-1 (1YGE)、大豆 LOX-3 (1JNQ)、人类 5-LOX (3O8Y 和 3V99) 和哺乳动物 15-LOX (1LOX) 的结构进行了对接分析。研究采用了不同尺寸的靶中心和对接盒以及空腔预测算法。这些化合物在 2.5 Μ 至 165 Μ 之间表现出抑制作用。在噻唑的第 4 位与一个电负性原子通过双键结合的取代基可提高活性。Docking 结果表明,LOX 结构 1JNQ、3V99 和 1LOX 可有效地用于估计这些化合物的 LOX 抑制作用和氨基酸相互作用。
