Without interfering with the high-salt-induced production of NFAT5 and its target genes, KRN2 specifically suppresses the expression of pro-inflammatory genes, such as Nos2 and Il6 [1]. KRN2 directly blocks the DNA binding region between NF-κB p65 and its Nfat5 exon 1 upstream site (base pairs -3000 to +1) and dose-dependently suppresses NF-κB p65's binding to Nfat5 promoter 1. exchanges [1].

| ln Vivo |
AIA, in which innate immune cells predominate, can be successfully inhibited by KRN2 (3 mg/kg, intraperitoneal injection, once day, for two weeks) [1]. In mice, CIA and AIA can be efficiently inhibited by KRN2 (3 mg/kg, intraperitoneal injection, daily), which also decreases the generation of pro-inflammatory cytokines, autoantibodies, and macrophage infiltration [1].

| Animal Protocol |
Animal/Disease Models: 8weeks old C57BL/6 mice were intradermally injected with 2 mg of Freund's complete adjuvant [1].
Doses: 3 mg/kg. Doses: intraperitoneal (ip) injection daily for 2 weeks Experimental Results: Effectively inhibits AIA. Animal/Disease Models: 8weeks old DBA/1J mice were immunized with bovine type II collagen [1]. Doses: 3 mg/kg. Mode of Route of Administration: Daily intraperitoneal (ip) injection. Experimental Results: Effectively inhibited CIA and AIA in mice and diminished the production of pro-inflammatory cytokines and autoantibodies as well as macrophage infiltration. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1.83 mg/mL (3.49 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 18.3 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1.83 mg/mL (3.49 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 18.3 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 1.83 mg/mL (3.49 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
