Western blot analysis of NLRP3 inflammasome-related protein expression in Citalopram-treated HK-2 cells at concentrations of 0, 10, 20, and 40 μM. GAPDH was used as the internal control. The LPS+ATP-induced NLRP3 inflammasome in HK-2 cells was incubated with the test compounds and LPS (2 μg/mL) for 24 h and subsequently treated with ATP (4 mM) for 2 h. # p < 0.05 compared with the LPS+ATP group. * p < 0.05 compared with the control group. Data are shown as the means ± standard deviations of three individual experiments, n = 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 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (7.71 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 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 (25.0 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.
