Myeloid differentiation protein 2 (MD2), a key TLR4 adaptor protein for sensing LPS, plays an important role in inflammatory process and has been identified as a promising target for the treatment of a variety of inflammatory diseases. In our study, a series of benzoxazolone derivatives were synthesized, characterized and tested for anti-inflammatory activity in vitro. The compounds 3c, 3d and 3g demonstrated
髓样分化蛋白2(MD2)是传感LPS的关键TLR4接头蛋白,在炎症过程中发挥着重要作用,并已被确定为治疗多种炎症性疾病的有希望的靶点。在我们的研究中,合成了一系列苯并恶唑酮衍生物,对其进行了表征并测试了其体外抗炎活性。化合物3c、3d和3g表现出最大的抗 IL-6 抗炎活性,IC 为50值分别为10.14±0.08、5.43±0.51和5.09±0.88μM。此外,bis-ANS 置换测定表明这些化合物竞争性抑制探针 bis-ANS 和 MD2 蛋白之间的结合。最活跃的化合物3g显示通过Arg90结合与MD2蛋白直接结合,并且通过生物层干扰(BLI)测定确定解离常数值为1.52×10 -6 mol L -1 。我们的研究结果表明,化合物3g可能是一种有前途的先导化合物,作为 MD2 抑制剂,用于进一步抗炎剂的开发。
