8-Hydroxyquinoline
Based on 1 publication(s) in Google Scholar
8-Hydroxyquinoline (8-Quinolinol) is a lipophilic metal chelator that can be used as a fungicide .8-Hydroxyquinoline shows the MIC range of 27.56-55.11 μM (4-8 μg/mL) against the clinical isolates of Neisseria gonorrhoeae. 8-Hydroxyquinoline can bind to copper form complexes and transport copper into cells. 8-Hydroxyquinoline increases in the number of micronucleated polychromatic erythrocytes and can also make hair depigmented in mice.

8-Hydroxyquinoline (8-OHQ) (Compd 1) (mixture of CuCl2 at 10.0 μM, 1 hour) binds to copper and form complexes can facilitate transport of copper into human breast cancer DCIS cells[2].
8-Hydroxyquinoline (mixture of CuCl2 at 1-20 μM; 1 or 8 hour) binds to copper and form complexes induces cell death with a time and dose-dependent manner in DCIS cells[2].
8-Hydroxyquinoline (mixture of CuCl2 at 1-5 μM, 2-12 hour) inhibits proteasomal chymotrypsin-like activity[2].
8-Hydroxyquinoline (0-100 μM, 30 min) acts to inhibit inflammation through inhibition of NO production and iNOS expression through blockade of C/EBPb DNA-binding activity and NF-jB activation in Raw 264.7 cells[3].

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: ≥ 2.5 mg/mL (17.22 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
