Metabolite Identification

Common Name

N-Acetyl-D-leucine

Description

N-Acetyl-D-leucine is a member of the amino acid derivative class, specifically an acetylated form of the D-enantiomer of leucine. Its chemical structure features an acetyl group attached to the nitrogen of the D-leucine backbone, which influences its biochemical interactions. N-Acetyl-D-leucine has been studied for its role in various metabolic pathways, particularly in relation to D-aminoacylase, where it exhibits substrate inhibition (K s = 35.5 ± 28.3 mM) (PMID:29509381 ). In comparative studies, N-acetyl-D-leucine has been evaluated alongside its isomers, revealing that it does not significantly impact behavioral recovery in models of vestibular compensation, unlike N-acetyl-L-leucine (PMID:26607469 ). This lack of effect is further supported by findings showing no significant changes in regional cerebral glucose metabolism (rCGM) in the vestibulocerebellum after administration of N-acetyl-D-leucine (PMID:25803613 ). Additionally, in brain and muscle tissues, N-acetyl-D-leucine levels were found to be higher than those of N-acetyl-L-leucine, which undergoes rapid conversion to L-leucine, suggesting a distinct metabolic fate for each isomer (PMID:32108176 ).
