  三甲氧基查尔酮衍生物抑制巴西利什曼原虫的生长：合成，生物学评估，分子建模和结构-活性关系（SAR）

  摘要：

  在这项工作中，我们描述了一系列查尔酮衍生物的合成，抗菌活性以及分子建模和结构-活性关系（SAR）评估。在这些化合物中，甲氧基查耳酮2h，2i，2j，2k和2l表现出显着的抗菌活性（IC 50  <10μM）。有趣的是2i（IC 50  = 2.7μM），2j（IC 50  =  3.9μM ）和2k（IC 50 = 4.6μM）衍生物表现出比对照药物喷他idine（IC 50 = 6.0μM）。我们的SAR研究表明，在苯环A上进行甲氧基二邻取代的重要性以及这些分子的前沿轨道HOMO系数分布与其活性之间的关系。活性最高的化合物2h，2i，2j，2k和2l符合Lipinski的5法则，这在理论上对于良好的药物吸收和通过生物膜的渗透非常重要。2j的电位分布（IC 50  = 3.9μM，CC 50  = 216μM）表明，这种查耳酮衍生物是一种命中化合物，需要在抗衰老药物设计中进一步探索。

  induced enzymes involved is potentially an important strategy for obtaining antiinflammatory agents. In the search for hits to obtain lead compounds for new drugs of this class, 14 synthetic chalcones derived from 2,4,6-trimethoxyacetophenone were evaluated in terms of their inhibitory action, in vitro, in relation to NO production in murine macrophages of the line RAW 264.7 induced by bacterial lipopolysaccharides

  通过改变所涉及的诱导酶的表达来抑制一氧化氮（NO）的产生可能是获得抗炎药的重要策略。为了寻找此类新药的先导化合物，在寻找成功的途径中，评估了14种衍生自2,4,6-三甲氧基苯乙酮的合成查耳酮在体外对小鼠巨噬细胞NO生成的抑制作用。细菌脂多糖（LPS）诱导的RAW 264.7品系。所有化合物都是在碱性条件下通过苯乙酮与相应的醛之间的醛缩合获得的。在四个独立的实验中，通过剂量与抑制作用曲线计算出的平均IC（50）值在1.34至27.60microM之间变化，并与阳性对照化合物1400W（IC（50）= 3）进行了比较。78microM），一种高度选择性的iNOS抑制剂（诱导型一氧化氮合酶）。八个查耳酮的平均IC（50）值小于或等于1400W的平均IC（50）值，这表明这些分子可能充当炎症过程的抑制剂。QSAR研究表明，B环中的吸电子基团似乎增加了亚硝酸盐生成的抑制，主要是在2位时。A环的邻位取代似乎是活性所必需的。

  A series of chalcones was evaluated as antimitotic agents. One of these, (E)-1-(2,5-dimethoxyphenyl)-3-[4-(dimethylamino)phenyl]-2-methyl-2-pr open- 1-one) (73), was found to be an effective antimitotic agent at a concentration of 4 nM in an in vitro HeLa cell test system. When evaluated in experimental tumor models in vivo, this compound exhibited antitumor activity against L1210 leukemia and B16 melanoma.

  22 Flavokawain derivatives (FKd) were obtained by one step syntheses in order to conduct a SAR study to understand the structural requirements for optimum and selective cytotoxicity. FKd and natural flavokawains A and B found into kava, a South Pacific traditional beverage, were evaluated against nine cancer and one healthy cell lines. The targeted cell cycle phases as well as the effects on the induction of apoptosis and cell cycle protein levels were investigated. Therapeutic improvements (more activity and selectivity) were achieved with FKd compared to natural flavokawains and notably with the 2',3,4',6'-tetramethoxychalcone (FKd 19). FKd induced a Gl/S arrest on p53 wild-type cells and an M arrest on p53 mutant-type, via the up-regulation of p21 and cyclin B1 proteins, followed by apoptosis. Moreover, FKd exhibited a 24 h-effect on Akt/mTor normal cells versus a 48 h-effect on Akt/mTor up-regulated cells. The SAR study resulted in the conclusion that trimethoxy A-ring allowed the best compromise between cytotoxicity and selectivity, as well as the substitution of the meta position on the B-ring and the use of halogens substituents.

  A series of 2'-substituted chalcone derivatives has been found to show potent inhibition of the production of IL-1beta from human peripheral blood monocytes stimulated with lipopolysaccharide (LPS), with IC50 values in the 0.2-5.0-muM range. Some members of the series have also shown inhibition of septic shock induced in mice by injection of LPS, although with low potency. Qualitative structure-activity relationships have shown that the enone is required for activity, which may be mediated by conjugate addition of a biological nucleophile to the chalcone. Electron-poor aromatic rings beta to the ketone give enhanced potency. Although electronic effects in the other ring (directly attached to the ketone) are minimal, this ring must possess an ortho substituent for good activity without cytotoxicity, suggesting a degree of selectivity which would not be expected for simple, nonspecific alkylating agents.

  Browning of fruits and vegetables is a serious issue in the food industry, as it damages the organoleptic properties of the final products. Overproduction of melanin causes aesthetic problems such as melisma, freckles and lentigo. In this study, a series of chalcones (1-10) have been synthesized and examined for their tryrosinase inhibitory activity. The results showed that flavokawain B (1), flavokawain A (2) and compound 3 were found to be potential tyrosinase inhibitors, indicating IC50 14.20-14.38 mu M values. This demonstrates that 4-substituted phenolic compound especially at ring A exhibited significant tyrosinase inhibition. Additionally, molecular docking results showed a strong binding affinity for compounds 1-3 through chelation between copper metal and ligands. The detailed molecular docking and SARs studies correlate well with the tyrosinase inhibition studies in vitro. The structures of these compounds were elucidated by the 1D and 2D NMR spectroscopy, mass spectrometry and single X-ray crystallographic techniques. These findings could lead to design and discover of new tyrosinase inhibitors to control the melanine overproduction and overcome the economic loss of food industry. (C) 2014 Elsevier B.V.
