Usage

Description

O-(2-AMinoethyl)-O'-[2-(Boc-aMino)ethyl]tetraethylene Glycol, also known as t-Boc-N-Amido-PEG5-amine, is a polyethylene glycol (PEG) derivative featuring a Boc-protected PEG linker with a free amino group and five PEG units. O-(2-AMinoethyl)-O'-[2-(Boc-aMino)ethyl]tetraethylene Glycol is characterized by its hydrophilic PEG spacer, which enhances solubility in aqueous media, and a reactive amino group that can interact with carboxylic acids and activated NHS esters. The Boc group can be deprotected under mild acidic conditions, freeing the amine for further reactions.

LDV peptidomimetics equipped with biotinylated spacer-arms: Synthesis and biological evaluation on CCRF-CEM cell line

The tripeptide Leu-Asp-Val (LDV) is known to bind α4β 1 integrin in leukemia cells. Here we have synthesized a LDV peptidomimetic equipped with a biotin-conjugated spacer-arm. Compound 9 acts as an inhibitor of the α4β1 integrin in an adhesion assay using fluorescently labeled, α4β 1 integrin-expressing leukemia CCRF-CEM cells. Furthermore, when bound to neutravidin-coated plates, compound 9 could capture CCRF-CEM cells. Such biotin-conjugated LDV peptidomimetic may thus represent a novel tool for biotechnological applications using avidin interaction for leukapheresis or leukemia cell targeting.
