DBCO-Val-Cit-PABC-OH Catalog number: BADC-01256

DBCO-Val-Cit-PABC-OH is a versatile linker used primarily in the field of targeted drug delivery. Here are some key applications of DBCO-Val-Cit-PABC-OH:

Antibody-Drug Conjugates (ADCs): DBCO-Val-Cit-PABC-OH is integral in the synthesis of Antibody-Drug Conjugates, where it serves as a cleavable linker between the antibody and the cytotoxic drug. In the tumor microenvironment, the linker is designed to be cleaved by specific enzymes, releasing the therapeutic agent directly to the target cells. This targeted delivery minimizes off-target effects and enhances the efficacy of anticancer therapies.

Click Chemistry: The DBCO group in DBCO-Val-Cit-PABC-OH enables its use in bioorthogonal “click” reactions, facilitating the attachment of biological molecules under mild conditions. This is particularly useful in labeling and tracking biomolecules in living systems, allowing researchers to study biological processes in real-time. Such applications enhance our understanding of molecular dynamics and interactions in complex biological systems.

Prodrug Development: DBCO-Val-Cit-PABC-OH can be employed in the design of prodrugs, which are inactive compounds that convert into active drugs once inside the body. The Val-Cit peptide linkage ensures that the drug is released in response to specific enzymatic activities found in target tissues, such as tumors. This approach improves the specificity and safety profile of the therapeutic agents, reducing systemic toxicity.

Controlled Drug Release: The cleavable nature of the Val-Cit-PABC linker allows for controlled release mechanisms in drug delivery systems. Researchers can design drug formulations that release their payloads in response to the physiological environment, optimizing the timing and dosage of drug delivery. This is particularly beneficial in chronic diseases where maintaining therapeutic levels of medication over extended periods is crucial.
