  Synthesis and Anti-bacterial Properties of Mono-carbonyl Analogues of Curcumin

  摘要：

  本文描述了三种单羰基姜黄素类似物的合成。对七种革兰氏阳性和革兰氏阴性细菌进行了体外抗菌活性测试，并讨论了取代基对芳环和连接张力的空间结构的影响。观察到，与姜黄素相比，部分衍生物显示出显著的活性，并且大多数衍生物对氨苄西林抵抗的阴沟肠杆菌表现出活性。化合物A12、B09、B13、B14和C09显示出显著的体外抗菌活性。结果显示，杂环或长链取代基可能增强姜黄素类似物的活性。

  The synthesis of three series of curcumin analogues with mono-carbonyl is described. Their in vitro anti-bacterial activities against seven Gram-positive and Gram-negative bacteria were tested and the effect of substituents on the aryl ring and the space structure of the linking strain were discussed. It was observed that part of the derivatives displayed significant activity when compared with curcumin and most of them exhibited activity against the ampicillin-resisted Enterobacter cloacae. Compounds A12, B09, B13, B14 and C09 show remarkable antibacterial activity in vitro. The result showed that heterocycle or long-chain substituents may enhance the activity of curcumin analogues.

  Curcumin has been extensively studied for its anti-inflammatory activities. However, its potential beneficial effects on various disease preventions and treatments are limited by its unstable structure. The beta-diketone moiety renders curcumin to be rapidly metabolized by aldo -keto reductase in liver. In the present study, a series of curcumin analogues with more stable chemical structures were synthesized and several compounds showed an enhanced ability to inhibit lipopolysaccharide ( LPS)-induced TNF-alpha and IL-6 synthesis in macrophages.

  A series of structurally novel mono-carbonyl curcumin analogues have been synthesized and biologically evaluated to test their inhibitory potencies and the structure-activity relationship (SAR) on human and rat 11 beta-hydroxysteroid dehydrogenase isoform (11 beta-HSD1) activities. 11 beta-HSD1 selective inhibitors have been discovered and compound A10 is discovered as a very potent with an IC50 value of 97 nM without inhibiting 11 beta-HSD2.
