D-DOPA
-DOPA (-3,4-dihydroxyphenylalanine; dextrodopa) is similar to -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 -DOPA is moderately effective in the treatment of Parkinson's disease (PD) and dopamine-responsive dystonia (DRD) by stimulating the production of dopamine in the brain, -DOPA is biologically inactive. See also * -DOPA (Levodopa; Sinemet, Parcopa, Atamet, Stalevo, Madopar, Prolopa, etc.) * -DOPS (Droxidopa) * Methyldopa (Aldomet, Apo-Methyldopa, Dopamet, Novomedopa, etc.) * Dopamine (Intropan, Inovan, Revivan, Rivimine, Dopastat, Dynatra, etc.) * Norepinephrine Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as both a hormone and neurotransmitter.
