Triazolo-β-aza-ε-amino acid and its aromatic analogue (AlTAA/ArTAA) in the peptide backbone mark a novel class of conformationally constrained molecular scaffolds to induce β-turn conformations. This was demonstrated in a Leu-enkephalin analogue and in other designed peptides.
Triazolo-β-aza-ε-氨基酸及其芳香类似物(AlTAA/ArTAA)在肽骨架中标记了一类新型的构象受限分子支架,可诱导β-转角构象。这在Leu-enkephalin类似物和其他设计的肽中得到了证明。
