Biological Activity

Description AS057278 (3-Methylpyrazole-5-carboxylic acid, MPC) is an inhibitor of D-amino acid oxidase (DAAO).
Targets
DAAO [2]
0.91 μM
In vitro

No inhibitory effect on DASOX were observed with AS057278 at the concentration of 10 μM and no inhibitory effect on serine racemase were observed with AS057278 at the concentration of 50 μM[2].

In vivo MPC is able to increase brain d-serine levels and ameliorate PCP-induced abnormal behavior in SD rat[1]. MPC increaseS D-serine fraction in rat cortex and midbrain (10 mg/kg i.v.). AS057278 was able to normalize phencyclidine (PCP)-induced prepulse inhibition after acute (80 mg/kg) and chronic (20 mg/kg b.i.d.) oral administration in mice. AS057278 after oral chronic treatment (10 mg/kg b.i.d.) was able to normalize PCP-induced hyperlocomotion[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
