  Synthesis of Cα methylated carboxylic acids: isosteres of arginine and lysine for use as N-terminal capping residues in polypeptides

  摘要：

  Replacement of the N-terminal alpha-amine with the isosteric methyl functionality in bioactive peptides can influence various pharmacokinetic parameters, including hydrophobicity and stability. C-alpha methylated amino acid analogues are thus of great interest to expand the repertoire of nonnatural synthons available as N-terminal 'capping' residues for peptide-based drug design. Several novel arginine and lysine analogues stereo selectively modified in the C-alpha position with a methyl group in place of the alpha-amine were prepared. (c) 2005 Elsevier Ltd.
