N-Carbamyl-L-glutamic acid

Uses

N-Carbamyl-L-glutamic Acid has been shown to have protective effects against ammonia intoxication and is used in the treatment of acute hyperammonemia.

Uses

carbamylphosphate synthetase activator

Definition

ChEBI: A urea that is the N-carbamoyl derivative of L-glutamic acid. An orphan drug used to treat a deficiency in the enzyme N-acetylglutamate synthase, which leads to acute hyperammonaemia.

Biological Activity

N-Carbamyl-L-glutamic acid (carglumic acid) is use to study its potential as a replacement therapy for N-acetylglutamate synthetase (NAGS) deficiency and to tre at hyperammonemia.

Synthesis

The general procedure for the synthesis of N-carbamoyl-L-glutamic acid from potassium cyanate and L-glutamic acid was as follows: 4 mmol of L-glutamic acid was dissolved in 20 mL of water and the solution was acidified using concentrated hydrochloric acid (37 μL, v/v). Subsequently, 12 mmol of potassium thiocyanate (KOCN) was added to the acidified solution. The reaction mixture was heated to 333 K under continuous stirring and maintained at this temperature for 4 hours. Upon completion of the reaction, the solution was cooled to room temperature and transferred to a glass vial sealed with a closure film, which was perforated to promote solvent evaporation until a white solid was observed to precipitate. Crystals of (I) suitable for X-ray single crystal diffraction analysis were grown at room temperature by slow evaporation of the ethanol solution (see Scheme 1). The yield of this synthetic method was 62% and the melting points of the resulting products ranged from 170°C to 171°C. This experimental procedure is an improvement and optimization of a previously reported method.
