Maltol
Based on 2 publication(s) in Google Scholar
Maltol, a type of aromatic compound, is an antioxidant agent. Maltol enhances neural function by mitigating oxidative stress and cell apoptosis. Maltol is an inhibitor of oxidative damage in nerve cells and is effective in preventing diabetic peripheral neuropathy (DPN). Maltol is used extensively as a safe flavoring agent and food preservative. Maltol is a metal ion chelator that can be used in the field of catalysis, cosmetics, and medicine.

Maltol (0.1-0.5 mM) significantly increases the viability of RSC96 cells co-incubated with H2O2, elevates anti-apoptotic Bcl-XL expression, and reduces pro-apoptotic BAX and caspase-3 expression[1].
Maltol (2 mM; pretreatment for 2 hours) protects SH-SY5Y cells from H2O2-induced oxidative damage through antioxidant and anti-apoptotic mechanisms[2].

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 (19.82 mM); Clear solution
