Synta66 is an inhibitor of Orai, which forms the pore of the CRAC channel. Synta66 (10 μM) attenuates peak SOCE in Müller glia. Synta66 (10 μM) prevents orai channels mediating the residual SOC current in Trpc1 / Müller cells[1]. Synta66 (10 μM) nearly completely blocks the Ca2+ entry signal evoked by CaCl2 addition, whereas it moderately reduces Ca2+ mobilization from stores with 10% to 30% in platelet. Synta66 (10 μM) suppresses human platelet activation in plasma and whole-blood thrombus formation. Synta66 (10 μM) also inhibits murine platelet responses and thrombus formation[2]. Synta66 (10 μM) inhibits LAD2 human mast cell line. Synta66 (10 μM) significantly inhibits FcεRI stimulated histamine and TNFα secretion, and has differential effects on FcεRI stimulated prostaglandin D2 and cytokine release in human lung mast cells (HLMCs)[3].

Solvent & Solubility
DMSO : 77.5 mg/mL (219.95 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: 2.58 mg/mL (7.32 mM); Suspended solution; Need ultrasonic and warming
This protocol yields a suspended solution of 2.58 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.8 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: ≥ 2.58 mg/mL (7.32 mM); Suspended solution
This protocol yields a suspended solution of ≥ 2.58 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.8 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Human Lung Mast Cell (HLMCs) are cultured in DMEM+Glutamax media containing 1% antibiotic-antimycotic solution, 1% non-essential amino acids, 10% fetal calf serum and supplemented with 100 ng/mL human stem cell factor, 50 ng/mL IL-6 and 10 ng/mL IL-10. For histamine assays mast cells are isolated from human lung tissue and used within 24 h[3].
