Solid phase peptide synthesis (SPPS) techniques are critical for developing and using peptides in various biomedical applications. However, typical synthesis routes used in SPPS are either resource-intensive (e.g., with automated synthesis or commercial services) or time-consuming (e.g., with manual benchtop synthesis). Here, a rapid manual synthesis method was developed to produce up to 8 peptides with fast cycle times simultaneously. Peptides synthesized manually were of equivalent or superior quality to those produced by in-house microwave-assisted automated peptide synthesis, with higher average crude purity of 70% compared to 50%. The method significantly reduced synthesis time, enabling the parallel coupling of up to 8 amino acids simultaneously in 15-20 min, as opposed to traditional benchtop peptide synthesis, which requires 80-150 min per amino acid. This approach offers an intermediate throughput between milligram-scale libraries and gram-scale single peptide synthesis, enabling rapid iteration for novel peptide designs without the need for expensive automated systems. As a result, peptide modifications, including incorporation of unnatural amino acids, can be explored, accelerating the development of peptides for a wide range of applications.
