IL-6 in a range of 81–89%, 09–42% at 10 and 1 μM, respectively, concentration. Exceptionally, the compound 20e was observed to be an effective inhibitor of TNF-α (54%) and IL-6 (97%), (47%) at 10 and 1 μM concentrations with minimum toxicity (22%) against CCK-8 cells. With few exceptions, all other compounds were found to be excellent inhibitors of IL-6 and moderate to excellent inhibitors of TNF-α, however
通过曼尼希反应合成了一系列含氮的二苯甲酮类似物,并评估了其对促炎细胞因子TNF-α和IL-6的抑制作用。研究了DPPH(1,1-二苯基-2-吡咯肼)的自由基清除活性及其动力学,从而确定了测试样品的抗氧化能力。所有合成的化合物在浓度分别为10和1μM时,对IL-6的活性均显示在81-89%,09-42%范围内。复合20e在浓度为10和1μM的条件下,MHC被认为是TNF-α(54%)和IL-6(97%)(47%)的有效抑制剂,对CCK-8细胞的毒性最小(22%)。除少数例外,发现所有其他化合物都是IL-6的优良抑制剂,是TNF-α的中度至优良抑制剂,但是这些化合物的毒性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16a,17g,18f,18g,19g和20e具有显着的抗氧化活性。
