Research background and challenges
Peptide cyclisation is an important strategy to enhance peptide stability, biological activity and selectivity. Traditional cyclisation methods (예를 들어. chemical cross-linking, enzymatic cyclisation) suffer from low efficiency and many side reactions. Click chemistry, as an efficient and modular synthetic method, provides a new solution for peptide cyclisation. 하지만, the traditional click chemistry method has poor selectivity, can only react at a single site, and has harsh reaction conditions, which limits its application in the field of peptide cyclisation. Based on click chemistry, we rely on the introduction of a modular design, and have successfully combined click chemistry with peptide cyclisation to achieve highly efficient and precise cyclisation technology.

Click chemistry-driven peptide cyclisation is a highly efficient and precise cyclisation technique, which provides new tools and methods for peptide cyclisation and has a broad application prospect. With the continuous development of click chemistry technology, it is believed that this technology will play an increasingly important role in the field of peptide science.
