Discovery and development of N-cadherin antagonists.

This article describes over 20 years of research on antagonists of the cell adhesion molecule, N-cadherin. Four types of antagonists are discussed: synthetic linear peptides, synthetic cyclic peptides, non-peptidyl peptidomimetics of the disulfide linked cyclic peptide N-Ac-CHAVC-NH(2) and monoclonal antibodies directed against the N-cadherin ectodomain. The biological activities of these antagonists are also discussed. In particular, the ability of N-cadherin antagonists to act as anti-cancer drugs is considered.
