What is Click Chemistry?

Click chemistry is a set of chemical reactions that are highly efficient, modular, and selective. These reactions are typically used for the synthesis of complex molecules and drug conjugates. Click chemistry reactions are characterized by their high yield, fast reaction rate, and compatibility with a wide range of functional groups. The most commonly used click chemistry reactions include copper-catalyzed azide-alkyne cycloaddition (CuAAC), strain-promoted alkyne-azide cycloaddition (SPAAC), and thiol-ene click reactions. These reactions have been widely used in drug discovery and development, bioconjugation, and materials science.

Application of PEG in Click Chemistry

In click chemical operations, PEGylation is frequently employed to improve the solubility, stability, and bioavailability of medicines and other compounds. Specifically, PEG is covalently joined to an interest molecule during PEGylation. PEGylation can improve the pharmacokinetics and pharmacodynamics of drugs by reducing their immunogenicity and clearance rate. PEGylation can also improve the effectiveness of click chemistry processes by increasing the solubility and stability of the reactants. Moreover, PEGylation can increase the bioactivity of drug conjugates made by click chemistry by decreasing non-specific binding and lengthening their stay in circulation.

Our PEG & Click Chemistry Technologies

BOC Sciences can provides click chemistry solutions for the synthesis of complex molecules and drug conjugates. Our PEGylation services can improve drug solubility, stability, and half-life, as well as reduce immunogenicity and toxicity. We also offer a variety of PEGylation linkers to ensure optimal conjugation efficiency and bioactivity.

Copper-catalyzed Azide-alkyne Cycloaddition (CuAAC)

Copper-catalyzed azide-alkyne cycloaddition (CuAAC) is one of the most widely used click chemistry reactions. CuAAC is the process by which a triazole ring is formed when an azide and an alkyne react with a copper catalyst. This reaction can be carried out under simple reaction conditions and is very efficient and selective. CuAAC is an effective tool for click and PEGylation chemistry. It allows for the efficient and selective conjugation of molecules, resulting in improved solubility, stability, and bioactivity. BOC Sciences offers a wide range of CuAAC services for PEGylation and click chemistry, as well as custom synthesis of PEGylated molecules and drug conjugates.

Strain-promoted Alkyne-azide Cycloaddition (SPAAC)

Strain-promoted alkyne-azide cycloaddition (SPAAC) is a type of click chemistry reaction that involves the reaction of an alkyne and an azide group in the absence of a copper catalyst. SPAAC is a highly efficient and selective reaction that can be performed under mild reaction conditions, making it ideal for PEGylation and click chemistry applications. Among the several SPAAC services offered by BOC Sciences are PEGylation, click chemistry, bespoke PEGylated molecule synthesis, and drug conjugates.

Thiol-ene Click Reactions

Thiol-ene click reactions are a type of click chemistry reaction that involves the reaction of a thiol group and an alkene group in the presence of a photoinitiator. One of the main applications of thiol-ene click reactions in PEGylation and click chemistry is the conjugation of PEG to a molecule of interest. This involves the functionalization of the molecule with a thiol or alkene group, followed by the reaction with a PEG derivative containing the complementary functional group. BOC Sciences supplies a wide range of thiol-ene click reaction solutions for PEG & click chemistry to facilitate the application of PEG in drug development and medical diagnostics.
