Application

Methoxypolyethylene glycol amine can:
  • Form dendritic micelles to enhance the solubility of hydrophobic compounds.
  • Conjugate with an anticancer drug methotrexate (MTX) to form MTX-PEG with potential application as drug carriers.
  • Couple with polyethylenimine (PEI) to form graft copolymers which can be used as nonviral gene vectors.

Other Notes

Oligomer used to prepare PEG-ylated conjugates having the advantage of reduced immunogenicity and increased serum half life
