Curcumin has been reported to possess multiple bioactivities, such as antioxidant, anticancer, and anti-inflammatory properties, however the clinical application of curcumin has been significantly limited by its instability and poor metabolism. Modification of curcumin has led to discovery and development of lots of novel therapeutic candidates. In recent years acute and chronic inflammation has been the focus of numerous studies in various diseases. Here, we synthesized a series of asymmetrical curcumin analogs with high in vitro chemical stability, and their anti-inflammatory activity was evaluated in LPS-stimulated macrophages. According to the bio-screening results and QSAR analysis, these analogs exhibited potent activities against LPS-induced TNF-α and IL-6 release. Among the analogs of the potent anti-inflammatory activity, compounds 3b8 and 3b9 exhibited significant protection and possess enhanced anti-inflammatory activity thereby attenuated the LPS-induced septic death in mice.
姜黄素已被报道具有多种生物活性,如抗氧化、抗癌和抗炎特性,然而其不稳定性及代谢特性不佳显著限制了其在临床中的应用。对姜黄素的改造已使得众多新型治疗候选药物的发现及开发成为可能。近年来,急慢性炎症已在多种疾病中成为众多研究的重点。本文合成了一系列体外化学稳定性高的非对称姜黄素类似物,并在LPS激发的小胶质细胞中评估了它们的抗炎活性。根据生物筛选结果及QSAR分析,这些类似物显示出对LPS诱导的TNF-α和IL-6释放的强大抑制作用。在具有强大抗炎活性的类似物中,化合物3b8和3b9表现出了显著的保护作用,并具有增强的抗炎活性,从而减轻LPS引发的小鼠败血性死亡。
