General description

3-Methylpyrazole-5-carboxylic acid is a potent and selective D-amino acid oxidase (DAO) (also known as DAAO, DAMOX and OXDA) inhibitor that protects DAO cells from oxidative stress induced by D-Serine. 3-Methylpyrazole-5-carboxylic acid specifically prevents formalin-induced tonic pain.

Non-competitive N-methyl-d-aspartate (NMDA) blockers induce schizophrenic-like behavior in healthy volunteers and exacerbate symptomatology in schizophrenic patients. Hence, a compound able to enhance NMDA neurotransmission by increasing levels of d-serine, an endogenous full agonist at the glycine site of the NMDA

The administration of the antilipolytic agents sodium nicotinate (1 mmole/kg i.p.) or sodium 5-methylpyrazole-3-carboxylate (0.5 or 1.0 mmole/kg i.p.) to alloxan-diabetic rats produced a significant reduction in the plasma concentration of free fatty acids and a slight reduction in blood

5-Methylpyrazole-3-carboxylic acid forms salts with basically substituted adenine bases of type (4) or (5), which have significantly more lipolysis inhibitory activity than the free acid itself. The substance tested, 6-amino-9-[2-hydroxy-3-(N-methyl-N-2-hydroxyethyl)-aminopropyl]-purine-5-methyl pyrazole-3-carboxylate (16), causes a significant reduction of serum FFA levels

L-Kynurenine (KYN), a tryptophan metabolite, is metabolized to kynurenic acid (KYNA), which is an antagonist of N-methyl-D-aspartate and alpha7 nicotinic acetylcholine receptors, by kynurenine aminotransferase (KAT) I and KAT II. In this study, optically pure KYN, namely L-KYN or D-KYN
