The core of peptide synthesis involves joining two amino acids to form a peptide bond, a reaction that inherently releases a water molecule. While this might suggest a natural fit for aqueous environments, the practical challenges of amino acid solubility, particularly for those with protecting groups, have historically favored organic solvents. Nevertheless, innovative strategies and the development of specialized reagents are overcoming these hurdles, making peptide coupling in water a viable and increasingly adopted practice.
Moving peptide coupling to water offers several compelling benefits. Foremost among these is the significant reduction in environmental pollution. Organic solvents used in traditional peptide synthesis are often volatile, toxic, and difficult to dispose of responsibly. By replacing them with water, laboratories can minimize their ecological footprint, leading to cleaner production processes.
Furthermore, water as a solvent is inherently safer for laboratory personnel.作者：S Hazra·2022·被引用次数：53—52 They nicely studiedamide and peptide couplings in water, with or without TPGS-750-M and EtOAc as a co-solvent to illustrate the specificity of each ...

From an economic perspective, water is far less expensive than most organic solvents, and its ready availability simplifies procurement and storage. The development of water-based solid-phase peptide synthesis (SPPS) also opens avenues for scalable and efficient peptide production.
A primary obstacle in peptide coupling in water has been the poor solubility of many protected amino acids, which are essential intermediates in synthetic peptide chains. These protecting groups, crucial for directing the reaction to the correct sites and preventing unwanted side reactions, often render the amino acids hydrophobic. However, researchers have developed several ingenious solutions to this problem:
