  Mechanistic Studies of Sanguinamide B Derivatives: A Unique Inhibitor of Eukaryotic Ribosomes

  摘要：

  Described are mechanistic studies of two Sanguinamide B (San B) derivatives. These compounds were identified as eukaryotic ribosomal inhibitors. Two biotinylated San B derivatives were synthesized and used to capture protein targets in a pull-down assay. LC/MS/MS analysis of the San B-captured targets identified several proteins that comprise eukaryotic ribosomal subunits. The translation inhibitory effect of San B was confirmed using an in vitro translation assay. Moreover, an evaluation of cell death mechanisms is reported.

  The first total synthesis of Sanguinamide B is reported, prepared via an efficient synthetic strategy. The natural product, trans,trans-Sanguinamide B (1), was generated in a thermodynamic ratio with trans,cis-Sanguinamide B (2) and cis,cis-Sanguinamide B (3). Complete conversion of the cis,cis-Sanguinamide B conformer (3) to the natural product (1) and the trans,cis- conformer (2) was achieved by

  We report the synthesis of three new sanguinamide B (San B) analogs. We substituted in amino acids along the San B backbone with an N-Me, glycine, or an aromatic moiety (Phe or D-Phe) generating twelve derivatives in total. Testing in HCT-116 colon cancer cell lines resulted in establishing a structure-activity relationship. Our data show that the substitution of L- or D-Phe adjacent to the thiazole in the San B backbone locks the macrocycle into a single conformer, but only D-Phe analogs are cytotoxic. We demonstrate that the conformation of the macrocycle is extremely sensitive to stereochemistry and amino acid placement. (C) 2014 Elsevier Ltd. All rights reserved.
