Folate-PEG1 acid is a small molecule linker that contains a folate group and a PEG (polyethylene glycol) chain. The folate group can selectively bind to folate receptors that are overexpressed on the surface of certain cancer cells, while the PEG chain can improve the solubility, stability, and biocompatibility of drugs. This linker is often used to attach drugs or imaging agents to folate receptors on cancer cells, enabling targeted delivery and enhanced efficacy. Folate-PEG1 acid is a valuable tool in the development of targeted therapeutics for various cancers, and has shown great promise in preclinical and clinical studies.
