Boc-D-Tyr(OtBu)-Aib-Glu(OtBu)-Gly-OH is a protected tetrapeptide used in peptide synthesis. The Boc (tert-Butoxycarbonyl) group protects the N-terminus of the D-tyrosine (D-Tyr) residue, preventing it from reacting during synthesis. The side chain hydroxyl group of D-tyrosine and the carboxyl group of glutamic acid (Glu) are protected by OtBu (tert-butyl) groups, which shield these functional groups until selective deprotection is needed. Aib (α-aminoisobutyric acid), known for its ability to induce helical structures, is the third residue, and Gly (Glycine), the final amino acid, has a free carboxyl group at the C-terminus, indicated by -OH, allowing for further coupling or modifications. This peptide incorporates D-tyrosine, Aib, glutamic acid, and glycine into peptide sequences, with specific protections to ensure controlled and efficient synthesis. Synonyms: yXEG; ((S)-5-(tert-Butoxy)-2-(2-((R)-3-(4-(tert-Butoxy)phenyl)-2-((tert-butoxycarbonyl)amino)propanamido)-2-methylpropanamido)-5-oxopentanoyl)glycine; Boc-D-Tyr(tBu)-Aib-Glu(tBu)-Gly-OH. Grade: ≥90%. Molecular formula: C33H52N4O10. Mole weight: 664.80.
Boc-D-Tyr(OtBu)-Aib-OH
Boc-D-Tyr(OtBu)-Aib-OH is a protected dipeptide used in peptide synthesis. The Boc (tert-Butoxycarbonyl) group protects the N-terminus of the D-tyrosine (D-Tyr) residue, preventing unwanted reactions during synthesis. The hydroxyl group on the D-tyrosine side chain is protected by an OtBu (tert-butyl) group, safeguarding it from reactivity until selective deprotection is desired. Aib (α-aminoisobutyric acid) is the second amino acid in the sequence, a non-natural amino acid known for inducing helical structures in peptides. The -OH at the C-terminus indicates a free carboxyl group, allowing for further peptide coupling. This compound is utilized to introduce D-tyrosine and Aib into peptides, with specific protections ensuring controlled and selective synthesis while incorporating structural constraints. Synonyms: Boc-D-Tyr(tBu)-Aib-OH; N-tert-Butoxycarbonyl-O4-tert-butyl-D-tyrosyl-alpha-methyl-alanine; (R)-2-(3-(4-(tert-Butoxy)phenyl)-2-((tert-butoxycarbonyl)amino)propanamido)-2-methylpropanoic acid.
