Decarboxylase

L-Ornithine ((S)-2, 5-diaminopentanoic acid) is a non-protein amino acid. L-Ornithine is mainly used in the urea cycle to remove excess nitrogen from the body. L-Ornithine is renoprotective. L-Ornithine has antifatigue effects.

Eflornithine hydrochloride hydrate (DFMO hydrochloride hydrate) is a specific and irreversible inhibitor of the ornithine decarboxylase (ODC). Eflornithine hydrochloride hydrate has antitumor activity and has also been used in the hirsutism Eflornithine hydrochloride hydrate has antitumor activity and is also used in the treatment of hirsutism.

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.

Tritoqualine is used as an inhibitor of histidine decarboxylase.
