Application:
5-Benzyl L-Glutamate N-Carboxyanhydride (H-Glu(OBzl)-NCA) (CAS: 3190-71-4) is used as the pharmaceutical intermediates. H-Glu(OBzl)-NCA can be used as an intermediate of Glatiramer Acetate (CAS: 147245-92-9). Glatiramer Acetate is a random basic synthetic copolymer of L-alanine, L-lysine, l-glutamic acid and L-tyrosine in a molar ratio of 6:1.9:4.7:1. Glatiramer acetate is an immunomodulator used in treatment of multiple sclerosis. 5-Benzyl L-Glutamate N-Carboxyanhydride is a reactive derivative of L-glutamic acid, where the amino acid has been cyclised as an N-carboxyanhydride (NCA), a class of reagent known as Leuchs’ anhydrides. 5-Benzyl L-Glutamate N-Carboxyanhydride reacts with nucleophiles such as alcohols and amines to form esters and amides respectively. The opening of the N-carboxyanhydride to an ester or amide releases the amino acid amine which can also react as a nucleophile leading to polymerisation. These poly-amide polymers have been investigated as delivery platforms of Small Interfering RNA (si-RNA).
