(S)-TROX-1
Based on 1 Customer Validation
(S)-TROX-1 is the S-enantiomer of TROX-1 (HY-120751). TROX-1 is a selective, orally active and brain-penetrant N-type calcium channel (Cav2.2) inhibitor with an IC50 value of 0.11 μM. TROX-1 exerts state-dependent and use-dependent inhibition, preferentially targets open/inactivated channels, blocks depolarization-associated calcium influx, and fully blocks calcium influx in rat dorsal root ganglion neurons. TROX-1 reverses inflammatory-induced hyperalgesia, nerve injury-induced allodynia. TROX-1 can be used for the research of pain.

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (229.96 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
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 (5.75 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 (5.75 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.
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.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Ca2+ Staining Technique
Ca2+ staining is an experimental technique that utilizes specific fluorescent probes (such as Fluo-4 AM, Fura-2, etc.) to qualitatively or quantitatively detect dynamic changes in intracellular Ca2+ concentrations; this is achieved by monitoring the changes in fluorescent signals generated when these probes bind to free intracellular calcium ions. The underlying principle relies primarily on the presence of chelating groups within the probe's molecular structure that possess high affinity for calcium ions.

Primary Dorsal Root Ganglion Sensory Neuron Culture
Primary dorsal root ganglion sensory neuron culture isolates DRG neuronal somata from rodent or human ganglia, dissociates tissue enzymatically and mechanically, and maintains post-mitotic sensory neurons in vitro for readouts such as neurite outgrowth, immunocytochemical marker expression, calcium imaging, electrophysiology, RNA/protein analysis, or neuropeptide release assays. The method reflects peripheral sensory neuron biology because DRG neurons are primary sensory neurons whose cell bodies reside in dorsal root ganglia and whose cultured dissociated cells can retain neuronal morphology, sensory-neuron marker expression, and stimulus-responsive properties depending on the downstream assay.
