Peptide Manufacturing Boc-N-Me-Ile-OH CAS NO. 52498-32-5

1. Peptide API Manufacturing

Boc-N-Me-Ile-OH is widely used as a protected N-methyl amino acid building block for the synthesis of therapeutic peptides and peptide active pharmaceutical ingredient (API) intermediates. The incorporation of an N-methyl isoleucine residue can improve metabolic stability and proteolytic resistance of peptide drug candidates.

2. Cyclic Peptide Synthesis

Boc-N-Me-Ile-OH is commonly employed in the preparation of cyclic peptides and macrocyclic peptide drugs. N-Methyl amino acids help to rigidify peptide conformations, enhance membrane permeability, and improve pharmacokinetic properties.

3. Peptide Optimization

Boc-N-Me-Ile-OH is used in lead optimization to introduce N-methyl amino acid residues into peptide sequences. N-Methylation can reduce hydrogen bond donation, improve oral bioavailability, and increase resistance to enzymatic degradation while maintaining biological activity.

4. Medicinal Chemistry

Boc-N-Me-Ile-OH serves as a chiral intermediate for the synthesis of peptide analogues and bioactive compounds. It is frequently used in structure–activity relationship (SAR) studies to evaluate the influence of N-methyl substitution on biological activity and physicochemical properties.
