Metabolite Identification
Common NameN-Acetyl-DL-leucine
DescriptionAcetylleucine, also known as tanganil, belongs to the class of organic compounds known as leucine and derivatives. Leucine and derivatives are compounds containing leucine or a derivative thereof resulting from reaction of leucine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Acetylleucine is also being developed as a possible treatment for several neurological disorders by IntraBio Inc. IntraBio is also investigating acetylleucine for the treatment of common inherited and acquired neurological diseases including Lewy body dementia, amyotrophic lateral sclerosis, restless legs syndrome, multiple sclerosis, and migraine Acetylleucine has received orphan drug designations from the U.S. Food & Drug Administration (FDA) and the European Commission. Acetylleucine is an extremely weak basic (essentially neutral) compound (based on its pKa). Acetylleucine is a modified amino acid used in the treatment of vertigo and cerebellar ataxia. Clinical trials with acetylleucine for the treatment of three orphan, fatal, neurodegenerative disorders are underway: Niemann-Pick disease type C, GM2 gangliosidoses (Tay-Sachs and Sandhoff diseases),, and ataxia–telangiectasia.
