Introduction to Peptide Linkers for ADC
Antibody - drug conjugates (ADCs) are a class of highly targeted therapeutic agents that combine the specificity of monoclonal antibodies with the potent cytotoxicity of small - molecule drugs. Peptide linkers play a crucial role in ADCs. They connect the antibody and the cytotoxic payload, and their properties significantly impact the performance of ADCs.
A good peptide linker should have several key characteristics. Firstly, it needs to be stable in the bloodstream to prevent premature release of the payload, which could lead to off - target toxicity. Secondly, it should be cleavable at the target site, such as within the tumor cells, to release the active drug. Peptide linkers can be designed to be cleaved by specific enzymes that are overexpressed in tumor tissues, like cathepsins. Additionally, the linker should not interfere with the binding affinity of the antibody to its antigen and should maintain the overall stability and pharmacokinetic properties of the ADC.
In China, there are several outstanding suppliers of peptide linkers for ADCs. Here are the top 10 suppliers in 2025:
