  Synthetic chalcones, flavanones, and flavones as antitumoral agents: Biological evaluation and structure–activity relationships

  摘要：

  A series of synthetic chalcones, flavanones, and flavones has been synthesized and evaluated for antitumor activity against the human kidney carcinoma cells TK-10, human mammary adenocarcinoma cells MCF-7 (estrogen receptor-positive), and human colon adenocarcinoma cells HT-29. The most active series is the chalcone ones with the best results against TK-10 and HT-29 cells. Fourteen out of 53 analyzed compounds resulted very active against at least two of the studied tumoral cells. Alkaline single cell gel electrophoresis, comet assay, was performed as a study of the chromosomal aberrations promoted by the compounds on normal cells. Four active and two inactive chalcones were studied in the comet assay against normal human kidney cells (HK-2). A structure-activity relationship analysis of these compounds was performed and for 4- and 3,4-disubstituted derivatives a quantitative correlation was obtained in the case of anti-HT-29 activity.

  for the conversion of 2′-hydroxychalcones to flavanones and flavones has been developed. The reagent efficiently promoted one-pot conversion of 2′-hydroxychalcones to flavones through flavanones involving cyclization and oxidative dehydrogenation. By changing the stoichiometery of the reagents, the reaction can be tuned to generate either flavanone or flavone. The developed protocol was found to be applicable

  A nanosilica-supported dual acidic ionic liquid on the basis of 1-methyl-3-(4-sulfobutyl)imidazolium hydrogen sulfate was synthesized and used as an efficient, green, non-corrosive, non-toxic, heterogeneous, and reusable catalyst for the synthesis of some new and known substituted flavanones. The synthesis was done by the condensation of 2'-hydroxyacetophenone with different aldehydes and the subsequent

  Design and synthesis of the simplified analogues as natural SLs alternatives provide a viable avenue for the efficient control of these parasitic weeds. We herein disclose the development of a novel class of SLs analogues derived from dihydroflavonoids as potent seed germinators of parasitic weeds. It was shown that one of them displayed a higher potential toward the seed germination of the broomrapes

  扫帚（Orobanche和Phelipanche spp。）和金缕梅（Strigaspp。）是一类寄生杂草，广泛分布于全球的热带，亚热带和温带地区。由于它们与宿主植物具有完全一致的生命周期，因此很难通过使用常规除草剂来选择性地控制它们。通过小分子信号传导剂诱导这些杂草种子的自杀萌发是管理寄生性杂草的有前途的策略。作为一类天然存在的萜类代谢产物，类固醇内酯（SLs）具有重要的生物学活性，包括刺激杂草种子发芽，抑制枝条分支等。但是，这些天然SL的广泛应用受到其极低的天然丰度和复杂的分子结构的极大限制。作为天然SL替代品的简化类似物的设计和合成为有效控制这些寄生杂草提供了可行的途径。我们在此公开了衍生自二氢类黄酮作为寄生杂草的有效种子发芽剂的新型SLs类似物的开发。结果表明，与阳性对照GR24相比，它们中的一个对扫帚种子的萌发具有更高的潜力。这些SLs类似物的结构-活性关系在对stragolac

  A synthesis of chiral flavanones via the condensation of tricarbonyl(h6-arylbenzaldehyde)chromium(0) and o-hydroxyacetophenone in a shorter time at room temperature have been developed. The tricarbonylchromium(0) group was removed by virtue of light and the enantioenriched flavanones was formed with highly enantioselectivity (> 95 % ee).
