Key Synthesis Methods
Solid-Phase Peptide Synthesis (SPPS)
Most widely used method. Peptides assembled on insoluble resin support. Highly adaptable for large-scale production.
Liquid-Phase Peptide Synthesis (LPPS)
Classical method for solution synthesis. Valuable for industrial-scale production of shorter peptides.
Hybrid Approaches
Combines SPPS and LPPS. Useful for longer peptides to improve yield and reduce waste.
Emerging Technologies
Continuous Flow SPPS
Uses pumps and columns. Reduces solvent use and reaction times.
Microwave-Assisted SPPS
Speeds up coupling reactions. Improves yields for difficult sequences.
Chemoenzymatic Synthesis
Employs enzymes for ligation. Greener alternative for longer peptides.
Challenges in High-Scale Synthesis
Yield and Purity
Decreases with peptide length
Cost
Excess reagents and high-purity amino acids
Waste
5-10 tons of solvent per kg of peptide
Purification
HPLC bottlenecks production
