  单酮类姜黄素对致龋菌的抗菌活性

  摘要：

  我们根据最低抑菌浓度 (MIC) 值评估了 25 种单酮类姜黄素 (MKC) 对一组有代表性的致龋菌的抗菌活性。姜黄素 A (10) 对变形链球菌 (MIC = 50 μg/ml) 和缓和链球菌 (MIC = 50 μg/ml) 显示出有前景的活性，以及​​对血链球菌 (MIC = 100 μg/ml)、干酪乳杆菌的中等活性(MIC = 100 μg/ml) 和唾液链球菌 (MIC = 200 μg/ml)。结果表明化合物 10 的活性高于其双β-二酮类似物。此外，化合物 3a（1,5-双（4-甲基苯基）戊烷-3-one）和 7b（1,5-双（4-溴苯基）戊烷-3-醇）对 S. mitis 具有中等活性（MIC = 100 μg/ml）和唾液链球菌（MIC = 200 μg/ml）。

• Effects of diarylpentanoid analogues of curcumin on chemiluminescence and chemotactic activities of phagocytes
  作者：Ibrahim Jantan、Syed Nasir Abbas Bukhari、Nordin Haji Lajis、Faridah Abas、Lam Kok Wai、Malina Jasamai

  A series of 43 curcumin diarylpentanoid analogues were synthesized and evaluated for their inhibitory effects on the chemiluminescence and chemotactic activity of phagocytes in vitro.

  The effects of the compounds on the respiratory burst of human whole blood and isolated human polymorphonuclear leukocytes (PMNs) were evaluated using a luminol-based chemiluminescence assay and their effect on chemotactic migration of PMNs was investigated using the Boyden chamber technique.

  Compounds 6, 17, 25 and 30 exhibited significant inhibitory activity on the oxidative burst of PMNs. The presence of methoxy groups at positions 2 and 5, and methoxylation and fluorination at positions 4 and 2 of both phenyl rings, respectively, may contribute significantly to their reactive oxygen species inhibition activity. Compounds 7, 17, 18, 24 and 32 showed strong inhibition of the chemotaxis migration of PMNs. Chlorination at various positions of both phenyl rings of cyclohexanone diarylpentanoid resulted in compounds with potent inhibitory effects on PMN migration.

  The results suggest that some of these diarylpentanoid analogues are able to modulate the innate immune response of phagocytes at different steps, emphasizing their potential as a source of new immunomodulatory agents.

  摘要 目的 合成了一系列43个姜黄素二芳基戊酮类似物，并评估它们对体外吞噬细胞化学发光和趋化活性的抑制作用。 方法 使用基于流明的化学发光测定法评估化合物对人全血和分离的人多形核白细胞（PMNs）呼吸爆发的影响，并利用Boyden室技术研究它们对PMNs趋化迁移的影响。 主要发现 化合物6、17、25和30在PMNs的氧化爆发上表现出显著的抑制活性。在两个苯环的2和5位置有甲氧基基团，以及在4和2位置分别有甲氧化和氟化基团的存在，可能会显著促进它们对活性氧化物种的抑制活性。化合物7、17、18、24和32显示出对PMNs趋化迁移的强烈抑制作用。在环己酮二芳基戊酮类似物的两个苯环的不同位置进行氯化，导致化合物对PMN迁移具有强效抑制作用。 结论 结果表明，这些二芳基戊酮类似物中的一些能够调节吞噬细胞的先天免疫反应的不同步骤，强调它们作为新的免疫调节剂来源的潜力。

  A series of 46 curcumin related diarylpentanoid analogues were synthesized and evaluated for their antiinflammatory, antioxidant and anti-tyrosinase activities. Among these compounds 2,13 and 33 exhibited potent NO inhibitory effect on IFN-gamma/LPS-activated RAW 264.7 cells as compared to L-NAME and curcumin. However, these series of diarylpentanoid analogues were not significantly inhibiting NO scavenging, total radical scavenging and tyrosinase enzyme activities. The results revealed that the biological activity of these diarylpentanoid analogues is most likely due to their action mainly upon inflammatory mediator, inducible nitric oxide synthase (iNOS). The present results showed that compounds 2,13 and 33 might serve as a useful starting point for the design of improved anti-inflammatory agents. (C) 2009 Elsevier Masson SAS. All rights reserved.

  Two series of curcumin analogues, a total of twenty-four compounds, were synthesized and evaluated. The most potent compound, compound 23, showed potent growth inhibitory activities on both prostate and breast cancer lines with IC50 values in sub-micromolar range,fifty times more potent than curcumin. Curcumin analogues might be potential anti-tumor agents for breast and prostate cancers. (C) 2009 Elsevier Ltd. All rights reserved.

  We evaluated the antimicrobial activity of 25 monoketone curcuminoids (MKCs) against a representative panel of cariogenic bacteria in terms of their minimum inhibitory concentration (MIC) values. Curcumin A (10) displayed promising activity against Streptococcus mutans (MIC = 50 μg/ml) and Streptococcus mitis (MIC = 50 μg/ml) as well as moderate activity against S. sanguinis (MIC = 100 μg/ml), Lactobacillus
