  Oxazole-Based Peptide Macrocycles:  A New Class of G-Quadruplex Binding Ligands

  摘要：

  Herein we report on the synthesis and DNA binding properties of a new class of water soluble oxazole-based peptide macrocycles that bind selectively to quadruplex DNA, with no detectable binding to duplex DNA. We have recently identified one quadruplex in the proto-oncogene c-kit that is suspected to act as a regulatory element for the expression of the c-kit gene. Here we provide the first example of a ligand binding to and stabilizing the c-kit quadruplex. Moreover, we show that these macrocycles show a preference for the c-kit quadruplex as compared to the human telomeric quadruplex.
