  TPA-induced up-regulation of activator protein-1 can be inhibited or enhanced by analogs of the natural product curcumin

  摘要：

  The activator protein-1 (AP-1) family of transcription factors, including the most common member c-Jun-c-Fos, participates in regulation of expression of numerous genes involved in proliferation, apoptosis, and tumorigenesis in response to a wide array of stimuli including pro-inflammatory cytokines, growth factors, stress, and tumor promoters. A number of plant polyphenols including curcumin, a yellow compound in the spice turmeric, have been shown to inhibit the activation of AP-1. Curcumin is a polyphenolic dienone that is potentially reactive as a Michael acceptor and also is a strong anti-oxidant. Multiple activities reported for curcumin, including inhibition of the stress-induced activation of AP-1, have been suggested to involve the anti-oxidant properties of curcumin. In the present study, a library of analogs of curcumin was screened for activity against the TPA-induced activation of AP-1 using the Panomics AP-1 Reporter 293 stable cell line which is designed for screening potential inhibitors. Numerous analogs were identified that were more active than curcumin, including analogs that were not anti-oxidants and analogs that were not Michael acceptors. Clearly, anti-oxidant activity or reactivity as a Michael acceptor is not an essential feature of active compounds. In addition, a number of analogs were identified that enhanced the TPA-induced activation of AP-1. The results from screening were confirmed using BV-2 microglial cells where curcumin and analogs were shown to inhibit LPS-induced COX-2 expression; analogs identified as more potent than curcumin in the screening assay were also more potent than curcumin in preventing COX-2 expression.

  Synthesis and biological evaluation of new curcumin derivatives as antioxidant and antitumor agents

  摘要：

  Twenty-four new compounds were prepared, taking curcumin as a lead, in order to explore their antioxidant and antitumor properties. The capacities of these derivatives to scavenge the 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical cation (ABTS(.+)), and to protect human red blood cells (RBCs) from oxidative haemolysis were investigated. In addition, the percentage viability of different cell lines (Hep G2, WI38, VERO and MCF-7) was tested. The result of the antitumor testing was generally in accordance with those of the antioxidant assays. Compounds which bear o-methoxy substitution to the 4-hydroxy function in the phenyl ring (7g, 5g and 3g) exhibited significantly higher ABTS(.+)-scavenging, antihaemolysis, and antitumor activities than other derivatives. In addition, molecular modelling studies were carried out for biologically active and inactive compounds, to study the structure-activity relationship, with the aim to elucidate which portions of the molecules are critical for the antioxidant and antitumor activity.

  anti-oxidant properties. There are conflicting reports concerning the structural/electronic basis of the anti-oxidant activity of curcumin. Curcumin is a symmetrical diphenolic dienone. A series of enone analogues of curcumin were synthesized that included: (1) curcumin analogues that retained the 7-carbon spacer between the aryl rings; (2) curcumin analogues with a 5-carbon spacer; and (3) curcumin

  从香料姜黄获得的天然产物姜黄素（二氟甲酰甲烷，1,7-双（4-羟基-3-甲氧基苯基）-1,6-庚二烯-3,5-二酮）具有多种生物活性，包括抗癌，抗炎和抗血管生成活性。这些生物活性中的一些可能源自其抗氧化特性。关于姜黄素抗氧化活性的结构/电子基础的报道相互矛盾。姜黄素是对称的二酚二烯酮。合成了一系列姜黄素的烯酮类似物，包括：（1）保留在芳基环之间的7-碳间隔基的姜黄素类似物；（2）具有5碳间隔基的姜黄素类似物; （3）具有3个碳间隔基的姜黄素类似物（查耳酮）。这些系列包括保留或不包含酚基的成员。通过TRAP测定法和FRAP测定法测定抗氧化活性。大多数具有抗氧化活性的类似物保留了类似于姜黄素的酚环取代基。但是，许多没有酚取代基的类似物也是有活性的。这些非酚类类似物能够形成稳定的以碳为中心的叔基。

  A method is described for cancer treatment through NFκB inhibition. NFκB is a direct or ultimate target for small molecule inhibitors. These small molecule inhibitors are aimed at suppression of NFκB directly or by indirect suppression of IKK, SFK kinases, or other upstream kinases. The present invention includes small molecule inhibitors comprising three, five, and seven carbon unsaturated spacers having one or two carbonyls, flanked by substituted aryl rings. The small molecule inhibitors can be symmetrical or unsymmetrical.
