Overview

(NH2) 7-8ARM-PEG BocNH heterodox eight arm polyethylene glycol $r $n is commonly used in drug delivery for multi site amine coupling loaded drugs/prodrugs or crosslinked with materials. The PEG star shaped structure brings high water solubility, low immune recognition, and stronger spatial shielding. Seven free amine groups can achieve high drug loading density or multi-point grafting fixation, while single arm Boc protection allows for a stepwise coupling strategy (first loading/fixing with 7-amine, and then removing Boc for secondary functionalization as needed), making it suitable for constructing long cycle, controllable modification direction, and flexible loading PEG delivery systems or nanocarrier surface branching platforms.

(NH2) 7-8ARM-PEG-BocNH heterodox eight armed polyethylene glycol

8-arm PEG (skeleton):Eight arm star shaped polyethylene glycol hydrophilic polymer core skeleton.

7arm-Amine（–NH ₂）：Free amine nucleophilic reaction sites at the seven arm ends.

1arm-Tert-Butyloxycarbonylamino（–NH-Boc）：A temporarily capped amino group with Boc protection at the end of one arm.

This molecule is commonly used in drug delivery for multi site amine coupling loading of drugs/prodrugs or crosslinking with materials. The PEG star shaped structure brings high water solubility, low immune recognition, and stronger spatial shielding. Seven free amine groups can achieve high drug loading density or multi-point grafting fixation, while single arm Boc protection allows for a stepwise coupling strategy (loading/fixation with seven amine groups first, followed by secondary functionalization by Boc removal as needed), making it suitable for constructing PEG delivery systems or nanocarrier surface grafting platforms with long cycles, controllable modification directions, and flexible loading.
