| 摘要 |
<p>Peptides containing at least one D-2-alkyltryptophan residue in their amino acid chain and having pharmacological activity similar to that of analogous peptides containing natural unsubstituted D-tryptophan residues in place of at least one D-2-alkyltryptophan. These new peptides are more resistant to oxidative degradation which usually takes place, for example, in the presence of reactive radicals or during high energy sterilization than unsubstituted tryptophan containing peptides.</p> |
