Cyclic analogues of neurotensin (NT) C-terminal fragments NT(8-13) and NT(9-13) were produced via intramolecular nucleophilic substitution of the Tyr(11) phenoxide anion on a 6-bromohexanoyl side chain substituted at position 8 or 9 and tested for NT receptor binding affinity.

Recent evidence is consistent with neurotensin (NT)(8-13) adopting a Type I beta-turn conformation while binding the NT receptor, which would place the cationic side-chains of Arg(8) and Arg(9) in close proximity. Thi...

Recent evidence is consistent with neurotensin (NT)(8-13) adopting a Type I beta-turn conformation while binding the NT receptor, which would place the cationic side-chains of Arg(8) and Arg(9) in close proximity. This was the basis for the design, synthesis and analysis of truncated NT(9-13) analogues 1-5 with dicationic position 9 side-chains to emulate the functions of the 8 and 9 side-chains of NT(8-13).
