N-Acetyl-L-proline Usage And Synthesis

Chemical Properties

white to off-white powder

Uses

N-Acetyl-L-proline is an aminoacid used in the synthesis of pharmaceutical compounds useful in preventing and treating disorders and syndromes associated with the nervous, vascular, musculoskeletal, o r cutaneous systems.

Definition

ChEBI: N-acetyl-L-proline is a N-acetyl-L-amino acid, a N-acylpyrrolidine, a pyrrolidinemonocarboxylic acid and a L-proline derivative.

Biochem/physiol Actions

N-acetyl-L-proline is an analog of the COOH-terminal dipeptide portion of preferred substrates of angiotensin-converting enzyme (ACE). It may be used in studies of the binding of substrates and inhibitors by ACE and to differentiate the specificities of various aminoacylases.

Description

N-Acetyl-L-proline (NALP) is an N-acetyl derivative of L-proline, which has wide application in medicine and is commonly utilized as a biologically active supplement. It can also act as an intermediate for synthesizing pharmaceuticals for preventing and treating some disorders and syndromes associated with the nervous, vascular, musculoskeletal, or cutaneous systems. In laboratories, it could play the role of a simple model for the secondary structure of proline-containing peptides. NALP can be acetylated from L-proline via a standard method, in the environment of acetic acid, or by the action of acetic anhydride on aqueous solutions of the products of the alkaline hydrolysis of gelatin followed by extraction. However,  these methods may result in the production of many byproducts[1].
