In the present work, a sterically constrained noncoded amino acid, 1-aminocyclohexane-1-carboxylic acid (Acc), was substituted in position 8 of the peptide chain of bradykinin (BK) and position 6, 7, or 8 of its B2 receptor antagonist [D-Arg0,Hyp3,Thi,(5,8)D-Phe7]BK, previously synthesized by

Endomorphin (EM2, Tyr-Pro-Phe-Phe-NH(2)) can assume various conformations related to cis/trans-rotamers of the amide linkage of Tyr-Pro. To control isomerization, restricted or flexible components have been introduced at the Pro position. We focused on [Chx(2)]EM2, an EM2 analogue substituting 1-aminocyclohexane-1-carboxlylic acid

Secondary structure formation and stability are essential features in the knowledge of complex folding topology of biomolecules. To better understand the relationships between preferred conformations and functional properties of beta-homo-amino acids, the synthesis and conformational characterization by X-ray diffraction analysis

The synthesis and some pharmacological properties of two sets of analogues, one consisting of six peptides with 1-aminocyclohexane-1-carboxylic acid (Acc) in position 2 and the other with the amino acid in position 3, have been described. All the peptides were

The delivery of large neutral amino acids (LNAAs) to brain across the blood-brain barrier (BBB) is mediated by the L-type neutral amino acid transporter present in the membranes of the brain capillary endothelial cell. In experimental animals, the L-system transporter
