  Design, synthesis and biological evaluation of estradiol-PEG-linked platinum(II) hybrid molecules: Comparative molecular modeling study of three distinct families of hybrids

  摘要：

  The synthesis of a series of 17 beta-estradiol-platinum(II) hybrid molecules is reported. The hybrids are made of a PEG linking chain of various length and a 2-(2'-aminoethyl)pyridine ligand. They are prepared from estrone in only 5 chemical steps with an overall yield of 22%. The length of the PEG chain does not influence the solubility of the compounds as it remains relatively constant throughout the series. MTT assays showed that the derivative with the longest PEG chain showed the best activity against two human breast cancer cell lines (MCF-7 and MDA-MB-231). The novel PEG-hybrids are also compared in terms of activities with two other families of 17 beta-estradiol-platinum(II) hybrids that we reported in previous studies. Molecular modeling study performed on a representative member of each family of hybrids reveals distinct molecular interactions with the estrogen receptor alpha which further corroborates their notably contrasting cytocidal activities on breast cancer cell lines. This study also shows that lipophilicity and the orientation of the tether chain between the estrogenic portion and the platinum(II) core contribute markedly to the biological activity of the various families of hybrids. The most active hybrids are those possessing an alkyl tether chain at position 16 beta of the steroid nucleus. For example. derivative 3 (p = 6) is about 16 times more potent on MCF-7 breast cancer cells than the corresponding 16 alpha-PEG-hybrids (2b) made in this study. (C) 2010 Elsevier Inc.
