4-Phenylimidazole(4-Phl) is used to study cytochrome P450 interaction with protein-ligand as a heme ligand in the crystallization process of recombinant human tryptophan 2, 3-dioxygenase.

Nitisinone (SC0735)(SC0735) is an enzyme 4-hydroxyphenylpyruvate dioxygenase inhibitor.

Benzylideneaniline (N-Benzylideneaniline) is a potent inhibitor of xyloglucan-α,β-dioxygenase, a key enzyme in the oxidative cleavage of the central double bond of xyloglucan.

4-Methylcatechol (3,4-Dihydroxytoluene) is a metabolite of homoprotocatechuic acid. It is both a substrate and a suicide inhibitor of Catechol 2,3-dioxygenase. 4-Methylcatechol (3,4-Dihydroxytoluene) is known to induce the production of brain-derived neurotrophic factor (BDNF). Recent studies have suggested that a lack of brain-derived neurotrophic factor (BDNF) in the limbic system may cause neuropathic pain.

4-Hydroxyphenylpyruvic acid is an enzyme inhibitor.4-Hydroxyphenylpyruvic acid (4-HPPA) is a keto acid that is involved in the tyrosine catabolism pathway. It is a product of the enzyme (R)-4-hydroxyphenyllactate dehydrogenase (EC 1.1.1.222) and is formed during tyrosine metabolism. The conversion from tyrosine to 4-HPPA is catalyzed by tyrosine aminotransferase. Additionally, 4-HPPA can be converted to homogentisic acid which is one of the precursors to ochronotic pigment. The enzyme 4-hydroxyphenylpyruvic acid dioxygenase (HPD) catalyzes the reaction that converts 4-hydroxyphenylpyruvic acid to homogentisic acid. A deficiency in the catalytic activity of HPD is known to lead to tyrosinemia type III, an autosomal recessive disorder characterized by elevated levels of blood tyrosine and massive excretion of tyrosine derivatives into urine. It has been shown that hawkinsinuria, an autosomal dominant disorder characterized by the excretion of 'hawkinsin,' may also be a result of HPD deficiency . Moreover, 4-hydroxyphenylpyruvic acid is also found to be associated in phenylketonuria, which is also an inborn error of metabolism. There are two isomers of HPPA, specifically 4HPPA and 3HPPA, of which 4HPPA is the most common.

1. Palmatine (Burasaine) is an inhibitor of dopamine generation. 2. Palmatine could potentially be developed for the treatment of flavivirus infections. 3. Palmatine has been used in the treatment of jaundice, dysentery, hypertension, inflammation, and liver-related diseases.

Indoximod (NLG-8189) is a methylated tryptophan with immune checkpoint inhibitory activity. Indoximod inhibits the enzyme indoleamine 2, 3-dioxygenase (IDO), which degrades the essential amino acid tryptophan, and may increase or maintain tryptophan levels important to T cell function. Tryptophan depletion is associated with immunosuppression involving T cell arrest and anergy.

2-Methylindole has antibacterial activity against Rhizoctonia solani and can inhibit indoleamine 2,3-dioxygenase and AchE. It is often used in organic synthesis and biochemical experiments.

IDO-IN-7 (NLG-919 analogue) is a potent inhibitor of the IDO (indoleamine-(2, 3)-dioxygenase) pathway.

IDO1-IN-1 (2 HzBTZ) is an indoleamine 2,3-dioxygenase 1 (IDO1) inhibitor.

4,5-Dichlorocatechol serves as a substrate for the broad-spectrum chlorocatechol 1,2-dioxygenase in Pseudomonas chlororaphis RW71. Its inhibition constant (Ki) values for the dioxygenase enzyme are 30 nM with the Chlorobenzoate-degrading strain Pseudomonas putida AC27, and 4 nM for the dioxygenase in Acidovorax sp. strain PS14.
