Pomalidomide-PEG2-azide is primarily utilized in the field of targeted drug delivery and bioconjugation. Its structure allows it to serve as a linker molecule, connecting therapeutic agents like pomalidomide to other biomolecules or drug carriers. This enables precise delivery of the drug to specific cells or tissues, enhancing therapeutic efficacy while minimizing off-target effects. It is particularly valuable in cancer research, where it aids in the development of antibody-drug conjugates (ADCs) or targeted therapies for conditions such as multiple myeloma. The azide group facilitates click chemistry reactions, allowing for efficient and stable conjugation with other molecules, while the PEG spacer improves solubility and reduces immunogenicity. This makes it a versatile tool in the design of advanced therapeutic systems.
