  Evaluation of dimerization–inhibitory activities of cyclic peptides containing a β-hairpin loop sequence of the EGF receptor

  摘要：

  Structure-activity relationships of cyclic peptides mimicking the beta-hairpin structure of the 'dimerization arm' at residues 242-259 of the EGF receptor are examined. Cyclic peptides containing the arm head of the beta-hairpin loop showed inhibitory activity toward the EGF receptor's dimerization. Cyclic peptides containing a Retro-Inverso sequence of the dimerization arm showed clear inhibitory effects on the dimerization in vitro and efficiently suppressed the proliferation of A431 cells, which abundantly express the EGF receptor on their surface. The effects at a specific hydrophobic site of the loop structure were expected to enhance the interactions with the receptor. (C) 2012 Elsevier Ltd. All rights reserved.
