New Ras CAAX mimetics : design, synthesis, antiproliferative activity, and RAS prenylation inhibition / C. Bolchi, M. Pallavicini, L. Fumagalli, N. Ferri, A. Corsini, C. Rusconi, E. Valoti. - In: BIOORGANIC & MEDICINAL CHEMISTRY LETTERS. - ISSN 0960-894X. - 19:18(2009), pp. 5500-5504.
Abstract:
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 antiproliferative 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.
