Pomalidomide-PEG6-NH2 hydrochloride is primarily used in the development of targeted drug delivery systems. Its structure allows for conjugation with therapeutic agents, enhancing their solubility and bioavailability. This compound is particularly valuable in cancer research, where it aids in the creation of prodrugs that can selectively target tumor cells while minimizing damage to healthy tissues. The PEG6 linker improves the pharmacokinetic properties of the drug, ensuring prolonged circulation in the bloodstream. Additionally, it is utilized in the synthesis of antibody-drug conjugates (ADCs), enabling precise delivery of cytotoxic agents to cancer cells. Its application extends to biochemical research, where it serves as a tool for studying protein interactions and cellular pathways.
