KRN5 is a possible therapeutic candidate because it is less toxic than BBR according to tests for cytotoxicity, hERG K+ channel, cytochrome inhibition, and liver microsomal metabolic stability [1]. KRN5 at 1 μM inhibited the expression of NFAT5, IL-6, MCP-1, and GM-CSF (NFAT5 target molecules) in LPS-stimulated RAW264.7 macrophages [1].

| ln Vivo |
KRN5 (15 mg/kg and 60 mg/kg) taken orally every other day for three weeks, beginning on day 21, dose-dependently lessens the severity of arthritis [1]. Additionally, there was a significant decrease in the amount of serum anti-type II collagen IgG in the mice treated with KRN5. LPS-stimulated splenocytes in KRN5-treated CIA mice produced a considerably lower amount of TNF-α and IL-6 than did the mice treated with vehicle [1].
|
| Animal Protocol |
Animal/Disease Models: 8weeks old DBA/1J mice were immunized with bovine type II collagen [1].
Doses: 15 mg/kg and 60 mg/kg. Route of Administration: Take orally every other day (every other day) for 3 weeks. Experimental Results: Arthritis severity was diminished in a dose-dependent manner. |

| Solubility (In Vitro) |
DMSO : ~5 mg/mL (~10.88 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: 0.5 mg/mL (1.09 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 5.0 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: 0.5 mg/mL (1.09 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 5.0 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. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
