  Sanguinamide B analogs: identification of active macrocyclic structures

  摘要：

  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.

  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.
