6-Maleimidocaproic acid Structural

What is 6-Maleimidocaproic acid?

Description

6-Maleimidocaproic acid contains a maleimide group and a terminal carboxylic acid. 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 maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.

Chemical properties

White to yellow solid, powder, crystals or crystaline powder.

The Uses of 6-Maleimidocaproic acid

6-Maleimidohexanoic acid is used as a probe for introducing maleimides groups into biomolecules and active pharmaceutical ingredients. Further, it is used with N-hydroxysuccinimide ester as a bifunctional cross-linking reagent. In addition to this, it acts as a probe for thiol groups in membrane proteins.

Definition

ChEBI: 6-Maleimidocaproic acid is a medium-chain fatty acid. It contains a maleimide group and a terminal carboxylic acid. 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 maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.

What are the applications of Application

6-Maleimidocaproic acid is a sulfhydryl reactive heterobifunctional crosslinking reagent. It can be widely used probe for introducing maleimides groups into biomolecules. A probe for thiol groups in proteins. Spacer Arm: 9.4 Angstroms. Probe for thiol groups (SH-groups) in membrane proteins.

Synthesis

Maleic anhydride (29.4 g, 0.3 mol) and 6-aminocaproic acid (39.35 g, 0.3 mol) were refluxed in glacial acetic acid (900 mL) for 16 h. Acetic anhydride (30.6 g, 0.3 mol) was added dropwise over a period of 2 hand reflux was continued for 1 h. The acetic acid was removed under vacuum at 70 °C to yield yellow syrup which solidified. The material was chromatographed over silica using dichloromethane-methanol-acetic acid (100:5:1) affording a crystalline solid (6-Maleimidocaproic acid).
