  New Ras CAAX mimetics: Design, synthesis, antiproliferative activity, and RAS prenylation inhibition

  摘要：

  Mimetics of the C-terminal CAAX tetrapeptide of Ras protein were designed replacing cysteine (C) by 2-hydroxymethylbenzodioxane or 2-aminomethylbenzodioxane, respectively etherified and amidified with 2'-methyl or 2'-methoxy substituted 2-carboxy-4-hydroxybiphenyl and 2,4-dicarboxybiphenyl. These pluri-substituted biphenyl systems, used as internal spacer and AA dipeptide bioisoster, were linked to the methyl ester Of L-methionine, glycine or L-leucine by an amide bond. The resultant twelve pairs of stereoisomers at the dioxane C-2 were tested for anti proliferative effect finding the maximum activity for derivatives with methyleneoxy linker between benzodioxane and 2'-methylbiphenyl. Of these compounds, the one with terminal methionine and S configuration proved a good Ras prenylation inhibitor in a cell-based assay. (C) 2009 Elsevier Ltd. All rights reserved.
