DSPE-PEG-Folate (DSPE-PEG-FOL) conjugate,which can be incorporated into liposomes as a targeting ligand. Folatereceptors are cellular surface markers for numerous solid tumors and myeloidleukemias.

Folate targeted drug delivery has emergedas an alternative therapy for the treatment and imaging of many cancers andinflammatory diseases. Due to its small molecular size and high bindingaffinity for cell surface folate receptors (FR), folate conjugates have theability to deliver a variety of molecular plexes to pathologic cells withoutcausing harm to normal tissues. Complexes that have been successfully deliveredto FR expressing cells, to date, include protein toxins, immune stimulants,chemotherapeutic agents, liposomes, nanoparticles, and imaging agents. Thisreview will summarize the applications of folic acid as a targeting ligand andhighlight the various methods being developed for delivery of therapeutic andimaging agents to FR-expressing cells.
