The syntheses and bioactivities of symmetrical curcumin and its analogues have been the subject of interest by many medicinal chemists and pharmacologists over the years. To improve our understanding, we have synthesized a series of unsymmetrical monocarbonyl curcumin analogues and evaluated their effects on prostaglandin E2 production in lipopolysaccharide-induced RAW264.7 and U937 cells. Initially
多年来,对称姜黄素及其类似物的合成和生物活性一直是许多药物化学家和药理学家关注的主题。为了增进我们的理解,我们合成了一系列不对称的单羰基姜黄素类似物,并评估了它们对脂多糖诱导的RAW264.7和U937细胞中前列腺素E 2产生的影响。最初,化合物8b和8c在LPS刺激的RAW264.7(8b,IC 50 = 12.01μM和8c,IC 50 = 4.86μM)和U937(8b,IC 50)中均表现出对PGE 2产生的强烈抑制作用。 = 3.44μM和8c,IC 50 = 1.65μM)细胞。在位置放置香兰素的Ar 2进一步提高效力时两种化合物15A和15B显著降低PGE 2分泌水平(RAW264.7:15A,IC 50 = 0.78μM和15b中,IC 50 = 1.9μM,而U937:15A,IC 50 = 0.95μM和15b,IC 50 = 0.92μM)。进一步的实验
