Delivery of polypeptides in multi-kilogram quantities within commercially competitive timelines is extremely challenging, especially when coupled with a desire to minimize environmental and economic impact. This case study explores how CPC Scientific’s advanced process improvements and efficiencies within solid-phase peptide synthesis (SPPS) have enabled multi-kilogram delivery of a pharmaceutically-relevant decapeptide within a challenging timescale, driving sustainable and cost-saving production for the client.
Our team has developed an innovative DMF recycling strategy that substantially reduces solvent consumption during solid-phase peptide synthesis. Minimizing use of DMF, a major environmental and cost contributor in peptide manufacturing, has improved process sustainability and cost efficiency. This method neatly demonstrates how targeted green chemistry practices can be successfully integrated into large-scale SPPS, supporting more environmentally responsible and economically viable peptide production.

In Part 1 of our Minimal Protection Group Strategies for SPPS, we discussed methods for eliminating sidechain protection on hydroxy-bearing amino acids such as serine, threonine, tyrosine, and hydroxyproline. By omitting t-butyl protection, we enhanced atom economy and avoided the use of hazardous solvents typically required to remove these protection groups. In Part 2, we present a new case study, expanding our approach to include the unprotected side chains of histidine, tryptophan, and arginine. We demonstrate the synthesis of a Goserelin peptide API impurity, showcasing how a convergent peptide fragment strategy can be used to eliminate the need for TFA and diethyl ether, eliminate side chain protection of Arginine, Histidine, and Tryptophan.
Solid-phase peptide synthesis (SPPS) approaches require that the side chains of certain amino acids be protected from undesired reactivity during synthesis. The installation and removal of these protection groups results in a lower atom economy in the production process. Removal of the protection groups often requires large volumes of trifluoroacetic acid (TFA) or other strong acids which can result in lower yields and pose a significant risk to the environment.
