  Solid phase synthesis of a ΨCH2NH pseudopeptide by ligation of a peptidyl aldehyde with a resin-bound amino peptide

  摘要：

  Solid phase synthesis of psi[CH2NH] pseudopeptide 3 was accomplished by reductive amination of peptidyl aldehyde 1 with resin bound amino peptide 2. No epimerization took place during the aldehyde preparation or the reductive amination step. This convergent strategy should facilitate the synthesis of analogues of the neuropeptide PACAP.

• Oxazole-Based Peptide Macrocycles:  A New Class of G-Quadruplex Binding Ligands
  作者：Katja Jantos、Raphaël Rodriguez、Sylvain Ladame、Pravin S. Shirude、Shankar Balasubramanian

  DOI：10.1021/ja064713e

  日期：2006.10.1

  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.
