Benserazide is an inhibitor of dopadecarboxylase. It is often given with levodopa in the treatment of Parkinson's to prevent the conversion of levodopa to dopamine in the periphery, thereby increasing the amount that reaches the central nervous system an
L-(-)-α-Methyldopa hydrochloride is an alpha-adrenergic agonist psychoactive drug. It is used as a sympatholytic or antihypertensive. Methyldopa has a dual mechanism of action. It is a competitive inhibitor of the enzyme DOPAdecarboxylase, which converts
Catalpalactone exhibits high antitermitic, and cytotoxic activities, it exhibits potent inhibitory effects on lipopolysaccharide-induced NO synthesis in RAW 264.7 cells , with IC50 values of 9.80 microM. Catalpalactone can inhibit dopamine biosynthesis by
Levadopa Related Compound A is the 6-hydroxy derivative of the amino acid L-DOPA with neurotoxic properties. Exogenously administered 6-Hydroxy-L-DOPA is biotransformed by an amino acid decarboxylase to the highly potent and catecholamine-selective neurot
Methylspinazarin is a naphthoquinone bacterial metabolite that has been found in Streptomyces and is an inhibitor of catechol O-methyltransferase (COMT; IC50 = 0.8 μg ml).1 It is selective for COMT over tyrosine hydroxylase, DOPAdecarboxylase, and dopamine-β-hydroxylase at 100 μg ml. Methylspinazarin decreases blood pressure in spontaneously hypertensive rats when administered at a dose of 50 mg kg. |1. Chimura, H., Sawa, T., Takita, T., et al.
