5-Hydroxyindole
Based on 1 Customer Validation
5-Hydroxyindole is an orally active hydroxylated indole and tryptophan metabolite. 5-Hydroxyindole activates α7 nicotinic acetylcholine receptors and acts on intestinal L-type calcium channels. 5-Hydroxyindole slows down the desensitization of 5-HT3 receptor-mediated ion currents in cells. 5-Hydroxyindole causes convulsions and loss of consciousness. 5-Hydroxyindole is used in the study of neuroblastoma, schizophrenia, and diseases related to intestinal motility disorders.

5-Hydroxyindole (1 mM) enhances the Acetylcholine-evoked glutamate release in rat cerebellar slices[2].
5-Hydroxyindole (1-10 mM) can increase the amplitude of the maximum ion current evoked by 5-hydroxytryptamine (HY-B1473A) in mouse N1E-115 neuroblastoma cells[3].
5-Hydroxyindole (30-300 mM) increases the amplitude of the field excitatory postsynaptic potential in rat hippocampal slices[4].
5-Hydroxyindole (100 μM; 30 min) significantly increases 5-HT release from RIN14B cells[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
5-Hydroxyindole (30 mg/kg; p.o.; daily; 11 days) significantly decreases the total gut transit time (TGTT) and increases the defecation frequency in wild-type Groningen (WTG) adult male rats[5].

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 (18.78 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (18.78 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
