1Object-affected harmful factors
If aqueous solutions are used in solid-phase peptide synthesis methods, then environmental impact is reduced and solvent consumption is lowered, but additional steps or specialized equipment are required, increasing operational complexity
Solution Approach 1:
The patent uses surfactants as intermediary substances to enable the condensation reaction between protected amino acids and peptides in aqueous media. The surfactant forms micelles that solubilize the hydrophobic protected amino acids and facilitate their reaction with peptides, thereby allowing environmentally friendly aqueous synthesis without requiring specialized equipment or complex additional steps
2Extent of automation
If conventional solid-phase peptide synthesis methods are used, then peptide synthesis can be automated, but large amounts of organic solvents are consumed
Solution Approach 1:
The patent changes the fundamental parameter of the reaction medium from organic solvents to aqueous solutions. By using water as the solvent and incorporating surfactants to enable reactant solubility and reaction efficiency, the method maintains automation capability while dramatically reducing organic solvent consumption and eliminating the need for repeated washing steps
