MPEG-amine (MW 4000)

MPEG-amine (MW 4000) can synthesize folate-conjugated polymer micelles for encapsulating the anticancer agent 9-nitrocamptothecin . Folate-conjugated polymer micelles serve as effective carriers for poorly soluble anticancer drugs, bypass macrophages, and utilize folate receptor (FR) -mediated endocytosis to target tumor cells.
