FA-PEG-PAsp(DIP)-CA

FA-PEG-PAsp(DIP)-CA/Folic acid-PEG-PAsp(DIP)-cholic acid is likely used in drug delivery systems, potentially for targeting tumors or other specific tissues. By combining the targeting ability of folic acid, the circulation-enhancing properties of PEG, and the absorption-promoting effect of cholic acid, this molecule could improve the efficacy and safety of drug delivery.

PAsp(DIP):

A di-peptide chain containing aspartic acid and a di-peptide, with amide linkages to the PEG and cholic acid.
