Applications & Uses

Description

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide is a water-soluble carbodiimide available as hydrochloride salt. This compound is a carboxyl- and amine-reactive crosslinker that is water soluble and can activate carboxyl residues for their reaction with primary amines to form O-acylisourea as a reaction intermediate, which reacts with amide bonds to release isourea as a by-product. It can crosslink the carboxy-group of glutamate and aspartate to the side-chain primary amine of lysine and the amino group at the N-terminus. The crosslinker readily reacts at a pH range of 4.5–7.2 and only crosslinks the residues within their van der Waals distance. 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide is also widely used in fabricating different nanosystems implemented in drug/protein delivery systems. It is mainly used for surface crosslinking/immobilization of drugs to increase stability against environmental changes, such as pH or temperature[1-2].

Uses

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide is used as a carboxyl activating agent and activate phosphate groups in phospho mono and di esters. It is used in peptide synthesis, 3'-amino-3'-deoxyadenosine-5'-di- and triphosphates and in the preparation of antibodies like immunoconjugates. It plays a vital role for immobilization of large biomolecules in association with N-hydroxysuccinimide. It is also used in the acylation of phosphoranes.

General Description

N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide is commonly used in combination with N-hydroxysuccinimide (NHS) in carbodiimide coupling reaction to activate carboxyl group for coupling with amines to form amides.
