C-terminal constrained phenylalanine as a pharmacophoric unit in peptide-based proteasome inhibitors
摘要:
Here we report the synthesis and biological properties of peptide-based molecules bearing constrained analogues of phenylalanine at the C-terminal. Compounds were tested as proteasome subunits' inhibitors. Dehydro-peptides showed good inhibition, in particular against trypsin-like (T-L) proteasome activity while some C-terminal Tic-derivatives inhibit only caspase-like activity in enzymatic beta 1 subunits with a certain degree of efficacy. The best analogues of the series demonstrated good resistance to proteolysis and a capacity to permeate the cell membrane. (c) 2007 Elsevier Masson SAS. All rights reserved.

A new approach to the synthesis of dipeptides is described based on the formation of the NHCHR1CONH–CHR2CO bond by carbenoid N–H insertion, rather than the formation of the peptide bond itself.
