Cliquez sur la cyclisation des peptides basée sur la chimie: technologie de cyclisation efficace et précise

Research background and challenges

Peptide cyclisation is an important strategy to enhance peptide stability, biological activity and selectivity. Traditional cyclisation methods (par exemple. 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. Cependant, 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.


Percée technologique

Innovative peptide cyclisation design: We have developed new peptide cyclisation methods based on click chemistry reactions such as CuAAC, SPAAC, and inverse electron demand Diels-Alder reaction.
Pioneering modular design: achieving rapid referencing of different moieties for peptide functionalization

Avantages techniques

High efficiency and precision: effectively improve the cyclisation efficiency, high selectivity, low by-products and simple purification.
Mild reaction conditions: no need for violent reaction conditions, applicable to a variety of easily degradable peptides.
Modular design: easy to introduce different functional groups to achieve peptide functionalization.

Areas of application

Click chemistry-driven peptide cyclisation technology has a wide range of application prospects in the following fields:
Peptide drug research and development: improve the stability, biological activity and cell membrane permeability of peptide drugs, and develop new peptide drugs.
Biomaterials: construct functionalized peptide materials for tissue engineering, drug delivery and other fields.
Chemical biology: study peptide-protein interactions and develop novel biological probes and drug targets.


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.

Biographie:Zejun Peng possède une vaste expérience en chimie organique et en synthèse peptidique. Il maîtrise l'application combinée de la synthèse peptidique en phase solide (SPSS) et synthèse peptidique en phase liquide (LPPS), et est particulièrement doué pour surmonter les « séquences extrêmement difficiles à synthétiser » (comme les peptides à chaîne ultra longue, séquences hautement hydrophobes, et repliement de liaisons disulfure multiples). Sous sa direction, l'équipe a réussi à surmonter les goulots d'étranglement techniques dans plusieurs modifications spécialisées (comme la N-méthylation, PEGylation, et étiquetage fluorescent), maintenir un taux de réussite de synthèse supérieur à 98%.
