Why Incorporate Fmoc-N-Methylated Building Blocks?

N-methylation replaces the amide hydrogen on the peptide backbone with a methyl group. This structural modification provides several biochemical advantages:

  • Conformational Rigidity: Restricts backbone flexibility, helping stabilize specific active peptide conformations for improved receptor selectivity.

  • Proteolytic Stability: Protects peptide bonds against enzymatic cleavage, extending in vivo half-life.

  • Preventing Aggregation: Disrupts interchain hydrogen bonding during SPPS, mitigating beta-sheet formation and aggregation during sequence elongation.
