Synthesis and biological evaluation of novel 2-heteroarylimino-1,3-thiazolidin-4-ones as potential anti-tumor agents
摘要:
A series of 35 heteroarylimino-1,3-thiazolidinones with three sites of functionalization were synthesized and their antiproliferative properties were studied. The in vitro screening by MTT assay was performed against five cancer cell lines (human colon cancer cell lines HT29, HCT116 and SW620 and breast cancer cell lines MCF7 and MDA-MB-231). It was observed that N3-substituted thiazolidinones had moderate activities whereas 5-benzylidene thiazolidinones showed promising activities. To investigate the mechanism of action, detailed biological studies of six selected compounds (those presenting the lower mitotic index) were carried out on the human colon cancer HT29 cell line. Cell cycle assay revealed that those compounds induced cell accumulation in G2/M and in subG0/G1 phases of cell cycle. Moreover, dissipation of mitochondria membrane potential was observed as well as redox changes in treated cells. (C) 2015 Elsevier Masson SAS. All rights reserved.
在这项工作中,我们描述了从3-氨基硒吩(使用硫光气)开始的3-isothiocyanatoselenophenes的合成。然后在氢氧化铵存在下将那些化合物转化为相应的硫脲。使用DDQ在2-氨基硒代[3,2- d ]噻唑中环化。使用相同的途径从3-异硫氰酸根合噻吩获得2-氨基噻吩并[3,2- d ]噻唑。
