Synthesis and growth inhibition activity of fluorinated derivatives of tamoxifen
摘要:
The design and synthesis of 11 fluorinated derivatives of tamoxifen are described. Growth inhibition values (GI(50)) on human HT-29, M21, MCF7, and MDA-MB-231 tumor cells are also reported. In general, the GI(50) values are similar or slightly higher than tamoxifen with the most active compound on MCF7 cell line having a GI(50) = 3.6 mu M. Surprisingly, as opposed to tamoxifen, both geometrical isomers behave similarly. We hypothesize that this behavior is due to in vitro isomerization of the compounds. (C) 2013 Elsevier Ltd.
