| Boc-Tyr(OtBu)-Leu-OH | Boc-Tyr(OtBu)-Leu-OH is a protected dipeptide used in peptide synthesis. The Boc (tert-Butoxycarbonyl) group protects the N-terminus of the tyrosine (Tyr) residue, preventing it from reacting during the synthesis process. The hydroxyl group on the tyrosine side chain is further protected by a tBu (tert-butyl) group, ensuring that it remains unreactive until selective deprotection is needed. Leu (Leucine) is the second amino acid in the sequence, contributing hydrophobic properties. The -OH at the C-terminus indicates a free carboxyl group, allowing for further peptide bond formation. This compound is used to introduce tyrosine and leucine into peptides while maintaining control over the reactivity of the functional groups for precise and efficient synthesis. Synonyms: ((S)-3-(4-(tert-Butoxy)phenyl)-2-((tert-butoxycarbonyl)amino)propanoyl)-L-leucine; Boc-Tyr(tBu)-Leu-OH; YL. Grade: ≥95%. Molecular formula: C24H38N2O6. Mole weight: 450.58. | |

It includes tyrosine (Tyr), ?-aminoisobutyric acid (Aib), glutamic acid (Glu), glycine (Gly), and leucine (Leu), with Boc (tert-Butyloxycarbonyl) and tBu (tert-butyl) groups protecting the amino and hydroxyl groups of tyrosine and glutamic acid residues. The peptide has a free -OH group at the C-terminus, allowing for further modifications or coupling. This nonapeptide is designed for controlled reactivity and stability, making it suitable for applications in peptide synthesis, drug design, and functional peptide research. Synonyms: Boc-Tyr(tBu)-Aib-Glu(tBu)-Gly-Glu(OtBu)-Glu(OtBu)-Tyr(OtBu)-Leu; ((S)-2-((S)-5-(tert-Butoxy)-2-((S)-5-(tert-butoxy)-2-(2-((S)-5-(tert-butoxy)-2-(2-((S)-3-(4-(tert-butoxy)phenyl)-2-((tert-butoxycarbonyl)amino)propanamido)-2-methylpropanamido)-5-oxopentanamido)acetamido)-5-oxopentanamido)-5-oxopentanamido)-3-(4-(tert-butoxy)phenyl)propanoyl)-L-leucine; Boc-Tyr(OtBu)-Aib-Glu(OtBu)-Gly-Glu(OtBu)-Glu(OtBu)-Tyr(OtBu)-Leu-OH; Boc-Tyr(tBu)-Aib-Glu(tBu)-Gly-Glu(tBu)-Glu(tBu)-Tyr(tBu)-Leu-OH.

| H-Glu(OtBu)-Glu(OtBu)-Tyr(OtBu)-Leu-OMe | H-Glu(OtBu)-Glu(OtBu)-Tyr(OtBu)-Leu-OMe is a protected tetrapeptide used in peptide synthesis. The sequence contains two glutamic acid (Glu) residues, a tyrosine (Tyr) residue, and a leucine (Leu) residue. The side chains of the glutamic acid and tyrosine residues are protected by OtBu (tert-butyl) groups, preventing their carboxyl and hydroxyl groups from reacting prematurely during the synthesis process. The N-terminus of the first glutamic acid is free, indicated by H-, and the C-terminus of the leucine residue is esterified as OMe (methyl ester), which can be used for further chemical modifications or as a temporary protection for the carboxyl group. This protected tetrapeptide is designed to facilitate the controlled and efficient incorporation of these amino acids into peptide chains. Synonyms: EEYL; tert-Butyl (S)-4-amino-5-(((4S,7S,10S)-7-(4-(tert-butoxy)benzyl)-4-isobutyl-15,15-dimethyl-3,6,9,13-tetraoxo-2,14-dioxa-5,8-diazahexadecan-10-yl)amino)-5-oxopentanoate; L-α-Glutamyl-L-α-glutamyl-O-(1,1-dimethylethyl)-L-tyrosyl-L-leucine 1,2-bis(1,1-dimethylethyl) 4-methyl ester; L-Leucine, L-α-glutamyl-L-α-glutamyl-O-(1,1-dimethylethyl)-L-tyrosyl-, 1,2-bis(1,1-dimethylethyl) 4-methyl ester.
