DSPE-PEG2000-iRGD is a PEG compound composed of DSPE and the αv-integrin targeting peptide (iRGD). The iRGD peptide binds to αv-integrins and subsequently undergoes proteolytic cleavage within tumors, producing CRGDK/R, which interacts with neuropilin-1. This compound is characterized by its tumor-targeting and tumor-penetrating properties, making DSPE-PEG2000-iRGD suitable for drug delivery applications.
