Azido-PEG4-Glu-Val-Cit-PAB-MMAE is a chemical conjugate used extensively in targeted cancer therapies. Here are some key applications of Azido-PEG4-Glu-Val-Cit-PAB-MMAE:

Antibody-Drug Conjugates (ADCs): Azido-PEG4-Glu-Val-Cit-PAB-MMAE is a critical linker-payload component in the development of ADCs. These conjugates consist of monoclonal antibodies specific to cancer cell antigens, linked to cytotoxic drugs via the Azido-PEG4-Glu-Val-Cit-PAB-MMAE linker. Upon binding to the cancer cell, the ADC is internalized and the cytotoxic drug is released, killing the cell while sparing healthy tissues.

Directed Drug Delivery: This conjugate is engineered for targeted drug delivery, enhancing the selective toxicity of chemotherapeutic agents. The PEGylation ensures increased solubility and stability, while the Val-Cit dipeptide ensures the payload is released specifically in the presence of tumor-specific proteases. This strategy minimizes systemic side effects and improves therapeutic efficacy.

Cell Imaging and Tracking: Azido-PEG4-Glu-Val-Cit-PAB-MMAE can be utilized in advanced cell imaging techniques. By tagging specific cells with this conjugate, researchers can track and image the distribution and proliferation of these cells in real-time. This application is critical for understanding tumor dynamics and the pharmacokinetics of therapeutic interventions.

Pharmacokinetic Studies: Researchers use Azido-PEG4-Glu-Val-Cit-PAB-MMAE in pharmacokinetic and biodistribution studies to assess the behavior of new drug candidates in the body. By conjugating drugs to this linker-payload, scientists can study how drugs are absorbed, distributed, metabolized, and excreted. These insights are vital for optimizing dosage regimens and improving drug safety profiles.

The molarity calculator equation

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2
