3-arm PEG5000-NCO

3-Arm PEG5000-NCO is a three-armed PEG derivative. The core structure of 3-Arm PEG5000-NCO consists of three PEG chains, each terminal of which is modified with an isocyanate (-NCO) group. The isocyanate groups in 3-Arm PEG5000-NCO can undergo rapid addition reactions with molecules containing amino (-NH2) or hydroxyl (-OH) groups to form stable carbamate or urea bonds, which can be used in applications such as constructing targeted drug delivery systems and modifying nanoparticles.

Description

In Vitro

The structure of PEG-NCO comprises two key parts that work synergistically:
Isocyanate (-NCO) group: Reacts with functional groups such as amino (-NH2) or hydroxyl (-OH) groups to form stable urea or carbamate bonds.
PEG chain: Acts as a hydrophilic spacer, forming a hydration layer on the particle surface, reducing non-specific adsorption and immune system recognition and clearance, thus prolonging the carrier's circulation time in vivo.
