  Synthesis and study of benzothiazole conjugates in the control of cell proliferation by modulating Ras/MEK/ERK-dependent pathway in MCF-7 cells

  摘要：

  By applying a methodology, a series of benzothiazole-pyrrole based conjugates (4a-r) were synthesized and evaluated for their antiproliferative activity. Compounds such as 4a, 4c, 4e, 4g-j, 4m, 4n, 4o and 4r exhibited significant cytotoxic effect in the MCF-7 cell line. Cell cycle effects were examined for these conjugates at 2 mu M as well as 4 mu M concentrations and FACS analysis show an increase of G2/M phase cells with concomitant decrease of G1 phase cells thereby indicating G2/M cell cycle arrest by them. Interestingly 4o and 4r are effective in causing apoptosis in MCF-7 cells. Moreover, 4o showed down regulation of oncogenic expression of Ras and its downstream effector molecules such as MEK1, ERK1/2, p38 MAPK and VEGF. The apoptotic aspect of this conjugate is further evidenced by increased expression of caspase-9 in MCF-7 cells. Hence these small molecules have the potential to control both the cell proliferation as well as the invasion process in the highly malignant breast cancers. (C) 2013 Elsevier Ltd.

  We report the visible-light-induced radical coupling reaction of silyl enol ethers with α-bromocarbonyl compounds to give 1,4-dicarbonyls. The reaction was effectively accelerated using an inexpensive organic dye (eosin Y) as a photoredox catalyst. 1,4-Dicarbonyl compounds alone were afforded, without the generation of carbonyl adducts of the α-halocarbonyls, which are usually generated in the presence

  我们报道了可见光诱导的甲硅烷基烯醇醚与α-溴羰基化合物的自由基偶联反应，得到1,4-二羰基。使用廉价的有机染料（曙红Y）作为光氧化还原催化剂可有效地促进反应。仅提供1，4-二羰基化合物，而没有生成α-卤代羰基的羰基加合物，α-卤代羰基的羰基加合物通常是在氟阴离子或路易斯酸的存在下生成的。将多种甲硅烷基烯醇醚，α-溴代酮，α-溴代酸酯和α-溴代酰胺应用于该系统以产生偶联化合物。

  1-Phenylpentane-1, 4-diones, and (E)-5-hydroxy-5-phenylpent-3-en-2-ones were synthesized via organophosphine-catalyzed addition reaction of but-3-en-2-one with aldehydes. The features of the present protocols include high selectivity, operational simplicity, atom economy, and mild reaction conditions without transition metals. © 2010 Wiley Periodicals, Inc.

  Alkyne-1,4-diols are readily available substrates which are isomerised to 1,4-diketones using Ru(PPh3)(3)(CO)H-2/xantphos as a catalyst. In situ cyclisation into furans, pyrroles and pyridazines has been achieved under suitable conditions. (C) 2009 Elsevier Ltd. All rights reserved.
• 2,5-Disubstituted furans from 1,4-alkynediols

  日期：2007.7

  1-4-Alkynediols serve as readily available starting materials for isomerisation to 1,4-diketones, which can be converted in situ into the corresponding furans by acid-catalysed dehydration. A range of 2,5-disubstituted furans was prepared using the ruthenium-based catalyst Ru(PPh3)(3)(CO)H-2 with Xantphos at 1 mol % loading. (C) 2007 Published by Elsevier Ltd.
