3-Hydroxyhippuric acid
Based on 1 publication(s) in Google Scholar
3-Hydroxyhippuric acid is an acylglycine. 3-Hydroxyhippuric acid inhibits kynureninase (Ki=60 μM). The concentration of 3-Hydroxyhippuric acid in autistic experimental groups is higher than that in control groups. 3-Hydroxyhippuric acid is a biomarker for Clostridium and is positively correlated with the content of Clostridium. 3-Hydroxyhippuric acid is one of the major metabolites of catechin-rich and wine polyphenol-rich diets. 3-Hydroxyhippuric acid can be used in the research of neurodegenerative diseases and autism spectrum disorders.

3-Hydroxyhippuric acid (four distinct concentrations) acts as a moderate competitive inhibitor of purified Homo sapiens kynureninase with a Ki of 60 μM[1].
3-Hydroxyhippuric acid (350 μM; 4-5 weeks) binds to the active site of Homo sapiens kynureninase at 80% occupancy, forming specific hydrogen bonds, π-stacking interactions, and ionic contacts, while inducing localized conformational shifts in active site and channel residues[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (10.66 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (10.66 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
