t-Boc-N-amido-PEG2-acid Usage And Synthesis

Description

t-Boc-N-amido-PEG2-acid is a PEG linker containing a terminal carboxylic acid and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The Boc group can be deprotected under mild acidic conditions to form the free amine.

Uses

Boc-NH-PEG2-CH2CH2COOH is a PEG-based PROTAC linker can be used in the synthesis of PROTAC[1].

IC 50

PEGs; Alkyl/ether
