d-amino acid oxidase

D-Amino acid oxidase, an enzyme that metabolizes exogenous D-amino acids in animals for detoxification, also regulates the level of D-serine in the brain [1].

Sodium benzoate (Benzoic acid sodium salt) is a D-Amino Acid Oxidase Inhibitor.Sodium Benzoate is a Food Preservative.

AS057278 (3-Methylpyrazole-5-carboxylic acid) is an D-amino acid oxidase (DAAO) inhibitor.

Luvadaxistat (TAK-831) is an orally active, potent and highly selective inhibitor of D-amino acid oxidase (DAAO) with an IC50 value of 14 nM for the oxidative deamination of D-serine.Luvadaxistat is used in the study of schizophrenia and cognitive disorders.

D-Cysteine, the D-isomer of cysteine, is a powerful inhibitor of E. coli growth and is mediated by D-amino acid oxidase to produce H2S, serving as a neuroprotective agent against cerebellar ataxia. Additionally, D-cysteine can inhibit the growth and cariogenicity of a two-species biofilm formed by Streptococcus mutans and Streptococcus hemoglobin.

D(-)-2-Aminobutyric acid is a substrate of D-amino acid oxidase.

Pyrrole-2-carboxylic acid (Minaline) was first identified as a degradation product of sialic acids, then as a derivative of the oxidation of the D-hydroxyproline isomers by mammalian D-amino acid oxidase. The latter relationship results from the lability of the direct oxidation product, A'-pyrroline-4-hydroxy-2-carboxylic acid, which loses water spontaneously to form the pyrrole. A similar reaction is catalyzed by the more specific allohydroxy-D-proline oxidase of Pseudomonas. In whole animal observations, pyrrole-2-carboxylate (PCA) ' was identified in rat or human urine after administration of the D-isomers of hydroxyproline, a finding ascribable to the action of D-amino acid oxidase. Urinary excretion of N-(pyrrole-2-carboxyl) glycine has been reported in a 5-year-old affected with type II hyperprolinemia; The child has mild developmental delay, recurrent seizures of the grand mal type and EEG alterations.

DAAO inhibitor-1 is a potent D-amino acid oxidase (DAAO) inhibitor with an IC50 of 0.12 μM.

D-Kynurenine (ZINC901103) is a metabolite of D-tryptophan and an agonist of GPR109B. D-Kynurenine activates AhR and promotes the conversion of the epithelium to mesenchyme. D-Kynurenine serves as a substrate in the fluorescence analysis of D-amino acid oxidase.

Thiolactomycin is a novel reversible dual inhibitor of D-amino acid oxidase (DAO) and D-Aspartate oxidase (DDO).

D-DOPA is an enantiomer of the dopamine precursor L-DOPA . It can be converted to L-DOPAviasequential oxidation and transamination, which are mediated by D-amino acid oxidase (DAAO) and DOPA transaminase, respectively, in rat kidney homogenates.1It reduces the number of dopaminergic neurons in primary rat embryonic mesencephalic cultures in a concentration-dependent manner.2Intraventricular administration of D-DOPA (200 μg/animal) increases striatal dopamine levels in rats.3D-DOPA (20 mg/kg, i.p.) induces contralateral turns in a rat model of Parkinson's disease induced by 6-OHDA .4 1.Wu, M., Zhou, X.-J., Konno, R., et al.D-dopa is unidirectionally converted to L-dopa by D-amino acid oxidase, followed by dopa transaminaseClin.

DAO-IN-1 (compound 10) is a potent DAO (D -amino acid oxidase) inhibitor with an IC50=269 ± 77nM for human DAO that ameliorates schizophrenia by increasing D -serine levels in the brain.

Sodium benzoate (Standard) is the standard substance of Sodium benzoate, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Sodium benzoate (Benzoic acid sodium salt) is a D-Amino Acid Oxidase Inhibitor.Sodium Benzoate is a Food Preservative.

Oganomycin GA is a fermentation product from the bacterium Streptomyces (Streptomyces str. oganonensis YG 19Z). By introducing sodium p-hydroxycinnamate into the fermentation medium, Oganomycin A is produced. Under the influence of D-amino acid oxidase, Oganomycin A is converted into the glutaric acid derivative Oganomycin GA, which exhibits greater efficacy against Gram-negative bacteria than against Gram-positive bacteria.

Oganomycin GB is derived from the bacterium Streptomyces (Streptomyces str. oganonensis YG 19Z). When sodium para-hydroxycinnamate is added to the fermentation medium, Oganomycin A is produced. This compound is converted into its glutaric acid derivative, Oganomycin GA, via the action of D-amino acid oxidase. After the removal of sulfate ester through acidic hydrolysis, both A and GA yield Oganomycin B and Oganomycin GB. The effectiveness of Oganomycin GB is greater against Gram-negative bacteria compared to Gram-positive bacteria.
