Based on biological properties of epoxyquinols from natural sources, bromo
and epoxyquinols derived from estrone were synthesized and screened against
Fem-X. HeLa and K-562 cell lines. Evidence was found that the bromine atom
and the epoxy moiety significantly increase the antiproliferative activity
within the series. (C) 2001 Elsevier Science Ltd. All rights reserved.
