In J774A.1 and BMDM cells, NIC-0102 (Compound 27) (7.5, 15, 30, 60 nM; 1h) selectively suppresses LPS-induced NLRP3 inflammasome activation [1]. Inducing NLRP3 polyubiquitination, NIC-0102 (7.5, 15, 30, 60 nM; 1h) inhibits the proteasome in LPS-primed J774A.1 cells during their activation step [1]. In LPS-primed J774A.1 cells, NIC-0102 (7.5, 15, 30, 60 nM; 1h) shows inhibitory effects on NF-κB during the priming step of the NLRP3 pathway [1]. In J774A.1 cells, LPS-induced NLRP3-ASC interaction and ASC oligomerization are blocked by NIC-0102 (15, 60 nM; 1h) [1].

Cell Viability Assay[1]
Cell Types: J774A.1 and BMDM cells (LPS primed) Tested Concentrations: 7.5, 15, 30, 60 nM Incubation Duration: 1 hour Experimental Results: Inhibition of IL-1β release in a dose-dependent manner. Western Blot Analysis[1] Cell Types: J774A.1 cells (LPS primed) Tested Concentrations: 7.5, 15, 30, 60 nM Incubation Duration: 1 hour Experimental Results: Dose-dependent inhibition of release of mature IL-1β and caspase- J774A.1 The presence of 1 p20 subunit in cell supernatants did not affect pro-IL-1β, pro-caspase-1, NLRP3, or ASC in cell lysates. Increased polyubiquitinated NLRP3 protein in a dose-dependent manner and Dramatically increased the amounts of c-Cbl and Cbl-b. At 60 nM, it demonstrated an inhibitory effect on NF-κB subunit p65, phosphorylated p65 and NLRP3 protein, and NF-κB-dependent TNF-α secretion was slightly diminished at this time.

| Animal Protocol |
Animal/Disease Models: Male C57BL/6 mice (6 to 8 weeks old; DSS-induced ulcerative colitis model) [1].
Doses: 0.125, 0.25 and 0.5 mg/kg Route of Administration: po (oral gavage); every 72 hrs (hrs (hours)) for 10 days. Experimental Results: Significant suppression of body weight and fecal occult blood. Colon length was shortened in a dose-dependent manner. Resulting in a dose-dependent decrease in tissue-associated IL-1β concentrations and significant inhibition of pro-IL-1β. Animal/Disease Models: Male C57BL/6 mice (6 to 8 weeks old) [1]. Doses: 0.5 mg/kg (intravenous (iv) (iv)injection); 1 mg/kg (oral) Route of Administration: intravenous (iv) (iv)injection; po (oral gavage); single. Experimental Results: 1.19 pharmacokinetic/PK/PK parameters of NIC-0102 in male C57BL/6 mice [1].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

| 5 mM | 0.4782 mL | 2.3910 mL | 4.7819 mL | |
| 10 mM | 0.2391 mL | 1.1955 mL | 2.3910 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
