Abstract A series of new chalcones containing fluoro atom at B ring have been designed, synthesized, and evaluated to be antiproliferative activity against a panel of human tumorcell lines. Some of the analogs (8, 9, 12, 45, 46 and 48) displayed powerful antiproliferative effects to certain human tumorcells, but all of them were devoid of any cytotoxicity towards the normal HEK 293.

摘要 已经设计、合成了一系列在 B 环上含有氟原子的新查尔酮,并评估了它们对一组人类肿瘤细胞系的抗增殖活性。一些类似物(8、9、12、45、46和48)对某些人类肿瘤细胞显示出强大的抗增殖作用,但它们都对正常的 HEK 293 没有任何细胞毒性。吖啶橙染色数据支持细胞毒性合成的类似物对肿瘤细胞的抗增殖作用是通过细胞凋亡介导的。化合物12和46使用 xCELLigence 测定法在人肝细胞癌细胞系中表现出浓度依赖性抗增殖活性。化合物对微管蛋白的计算机分子对接研究进一步支持了结构和抗增殖活性的关系,这表明我们的化合物干扰细胞分裂。 由 Ramaswamy H. Sarma 传达
Synthesis and anti-proliferative activity of fluoro-substituted chalcones
fluoro-substituted chalcone derivatives have been synthesized. All synthesized compounds were characterized by 1H nuclear magnetic resonance (NMR), 13C NMR, and elemental analysis. Their anti-proliferative activities were evaluated against five cancer cells lines, namely, A549, A498, HeLa, A375, and HepG2 using the MTT method. Most of the compounds showed moderate to high activity with IC50 values in
已经合成了一系列新颖的氟取代的查耳酮衍生物。所有合成的化合物均通过1 H核磁共振(NMR),13 C NMR和元素分析进行表征。使用MTT方法评估了它们对五种癌细胞系,即A549,A498,HeLa,A375和HepG2的抗增殖活性。大多数化合物显示出中等至高活性,IC 50值为0.029–0.729μM。在所有合成的化合物中,有10和19个对癌细胞表现出最有效的抗增殖活性,其中10个被认为是最有前途的化合物。

Flavonoids are plant phenolic compounds that have many interesting medicinal properties. Therefore, there is interest in the synthesis of non-natural flavonoids as they may possess new or enhanced biological activities. In this study, metabolically engineered Saccharomyces cerevisiae expressing 4-coumaroyl:CoA-ligase (4CL) and chalcone synthase (CHS) was explored as a platform for producing non-natural flavanones and dihydrochalcones. By precursor addition of cinnamic acid analogues to the engineered yeast, numerous non-natural flavanones and dihydrochalcones were formed in vivo. Also, several CHS derailment products were formed. Of the isolated compounds, one flavanone and three derailment products were found to be novel compounds. (C) 2010 Elsevier B.V. All rights reserved.
