Description

DL-DOPA, also known as (+-)-DOPA or (R,S)-DOPA or DL-3,4-dihydroxyphenylalanine is an alpha amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). DL-DOPA also belongs to the class of organic compounds known as tyrosines and derivatives. Tyrosines and derivatives are compounds containing tyrosine or a derivative thereof resulting from reaction of tyrosine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. DL-DOPA is a racemic mixture of both D-DOPA and L-DOPA. D-DOPA is similar to L-DOPA (levodopa), but with opposite chirality. Levo- and dextro- rotation refer to a molecule's ability to rotate planes of polarized light in one or the other direction. Whereas L-DOPA is moderately effective in the treatment of Parkinson's disease (PD) by stimulating the production of dopamine in the brain, D-DOPA was at one time thought to be biologically inactive. However, it has recently been found that D-DOPA can be converted to L-DOPA and then to dopamine via the human enzyme known as D-amino acid oxidase and that racemic mixtures of DL-DOPA can be effective in treating Parkinsonism (PMID: 17924443 ; PMID: 3129126 ; PMID: 17042912 ). The biological production or biosynthesis of D-DOPA is thought to occur through bacterial conversion of tyrosine. L-DOPA is found naturally in both animals and plants. It is made via biosynthesis from the amino acid L-tyrosine by the enzyme tyrosine hydroxylase. L-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines.
