Purity: ≥98%
SD-06 is an inhibitor of p38 alpha MAP kinase which inhibits p38α with an IC50 value of 170 nM and inhibits LPS-stimulated TNF-release in rats with 83% inhibition at an oral dose of 1mg/kg. It could be applied to the treatment of arthritis.
| Targets |
p38 MAPK (IC50 = 110 nM)
|
|---|---|
| ln Vitro |
SD0006 is selective for p38α kinase over 50 other kinases screened (including p38γ and p38δ with modest selectivity over p38β). In cellular studies, it reduces the release of inflammatory mediators. Multiple proinflammatory proteins are expressed less frequently when SD0006 is present, both at the transcriptional and translational levels. While SD0006 has no direct COX-1 or COX-2 inhibitory activity in RASFs, it was able to completely inhibit the release of IL-1β-stimulated PGE2 with an IC50 of 96.2 nmol/l[1].
|
| ln Vivo |
In animal models of chronic inflammation and disease, SD0006 is successful in vivo. It has significant protective effects on bone density and paw joint integrity in the rat streptococcal-cell-wall induced arthritis model, demonstrating its efficacy. Additionally, SD0006 exhibits good oral anti-inflammatory efficacy and excellent interspecies agreement in rats, cynomolgus monkeys, and humans. In a rodent model of acute inflammation, it reduces pain and swelling[1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.28 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 25.0 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: ≥ 2.5 mg/mL (6.28 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 25.0 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. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (6.28 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.
