Abstract A series of asymmetric indole curcumin analogs were synthesized and evaluated as possible inhibiters of pro-inflammatory enzymes such as COX-2, pro-inflammatory cytokines as TNF-α and IL-6, trypsin and β-glucuronidase. They were also tested for antioxidant activities. The results showed that compounds 5e and 5h were found to be the most potent inhibitors of COX-2 (83.33%, 82.50%) and β-glucuronidase
摘要合成了一系列不对称吲哚姜黄素类似物,并作为可能的促炎酶抑制剂,如COX-2,促炎细胞因子如TNF-α和IL-6,胰蛋白酶和β-葡萄糖醛酸苷酶抑制剂。还对它们的抗氧化活性进行了测试。结果表明,化合物5e和5h是最有效的COX-2抑制剂(83.33%,82.50%)和β-葡萄糖醛酸苷酶(67.80%,64.12%)。在10 µM的浓度下,所有合成的化合物在71-100%的范围内均显示出对IL-6的有希望的活性。化合物5f,5h,5e,5c和5d对TNF-α(28-51%)和IL-6(87-98%)表现出显着的抑制作用,对CCK-8细胞的毒性低(45-51%)。除少数例外,发现所有其他化合物均对优秀的IL-6抑制剂和中度TNF-α抑制剂有良好的作用。然而,这些化合物的毒性特征需要在进一步的优化研究中加以改善。在测试的化合物中,发现5c,5b,5j和5g具有出色的还原活性,而5b,5c和5h是中等的DPPH(1
