proinflammatory induction. We previously demonstrated that the mono-carbonyl analogues of curcumin possessed improved pharmacokinetic profiles both in vitro and in vivo. In this study, we synthesized and examined a series of 5-carbon linker-containing mono-carbonyl analogues of curcumin with potent inhibitory activities against TNF-α and IL-6 release in LPS-stimulated RAW 264.7 macrophages. Discussion and conclusions
据报道姜黄素具有多功能的生物活性,特别是抑制促炎性诱导的能力。我们以前证明姜黄素的单羰基类似物在体外和体内均具有改善的药代动力学特征。在这项研究中,我们合成并检查了一系列含有5个碳连接基的姜黄素单羰基类似物,它们对LPS刺激的RAW 264.7巨噬细胞中的TNF-α和IL-6释放具有有效的抑制活性。给出了关于构效关系(SAR)的讨论和结论。被测化合物中两种最有效的类似物B75和C12,在巨噬细胞中表现出剂量依赖性的抗炎能力。这增加了姜黄素的单羰基类似物可能用作治疗各种炎性疾病的潜在药物的可能性。
