Carbidopa (Lodosyn) is an aromatic-L-amino-acid decarboxylase inhibitor (IC50: 29±2 μM). It is used in PARKINSON DISEASE to reduce peripheral adverse effects of LEVODOPA.

α-Hydroxyglutaric Acid Lithium, converted from glutamate in microorganisms and animals, is an inhibitor of α-ketoglutarate-dependent dioxygenase and 5-methylcytosine hydroxylase, and has an inhibitory effect on ATP synthase and mTOR signaling.

Carbidopa monohydrate (S(-)-Carbidopa) is an inhibitor of DOPA decarboxylase, preventing the conversion of levodopa to dopamine.

4-bromo-3-hydroxybenzoic acid is a potent inhibitor of the enzyme histidine decarboxylase.
