the combined use of FT‐IR, NMR and MS spectral data. All the compounds were screened in vitro for their ability to inhibit the enzyme xanthine oxidase as per the reported procedure along with DPPH free radical scavenging assay. Compounds 5j, 5k and 5l demonstrated satisfactory potent xanthine oxidase inhibitory activities with IC50 values, 3.6, 8.1 and 9.9 μm, respectively, whereas compounds 5k, 5n and
设计并合成了一系列2-(取代的苄基氨基)-4-甲基噻唑-5-羧酸,作为非布索坦的结构类似物。与将环直接与噻唑部分连接的非布索坦相比,亚甲基胺间隔基被结合在苯环和噻唑环之间。引入亚甲基胺的目的是提供一种杂原子,该杂原子有望促进黄嘌呤氧化酶活性位点残基内的氢键键合。所有化合物的结构都是通过结合使用FT-IR,NMR和MS光谱数据确定的。根据所报道的方法连同DPPH自由基清除测定法,体外筛选所有化合物抑制黄嘌呤氧化酶的能力。化合物5j,5k和5升证明令人满意的效黄嘌呤氧化酶与IC抑制活性50个值,3.6,8.1和9.9 μ米分别,而化合物5K,5N和5P证明具有IC适中的抗氧化活性50 15.3,17.6和19.6 μ米分别连同黄嘌呤氧化酶抑制活性。与非布索坦相比,化合物5k显示出适度的黄嘌呤氧化酶抑制活性以及抗氧化活性。还研究了所有化合物在酶活性位点(PDB ID-1N5X)的结合亲和力。
