JNK3 inhibitor-4 (compound 15d) (1, 5, 10, 20 μM; 24 h or 48 h) prevents transported primary cortical neurons from being cytotoxically affected by Aβ1-42 [1]. 10 μM Aβ1-42 or 0.5 μM Anisomycin induces c-jun phosphorylation and APP phosphorylation in cortical neurons; JNK3 inhibitor-4 (50 μM; 4 10, 20 μM; 24 h, 48 h) blocks these processes [1]. h) The Caco-2 test revealed that it was highly permeable, and the PAMPA test indicated that it had blood-brain barrier (CNS+) permeability based on an effective permeability coefficient (Pe) > 4 [1]. JNK3 inhibitor-4 also has IC50 values of 5.78, 11.7, 15.1, 1.18, 3.10, 1.19, 0.280, 0.970, 0.860, and 0.340 μM, respectively, and inhibits GSK3α (h), GSK3β (h), JNK1, 2, MKK6, MOK, SAPK2a (h), SAPK2a (T106 M) (h), SAPK2b (h), MKK4, JNK1α1 (h), and JNK2α1 (h).

ln Vivo |
JNK3 inhibitor-4 (compound 15d) can improve cognition in Alzheimer's disease models. JNK3 inhibitor-4 (10 mg/kg or 30 mg/kg; intravenous injection; 3 times a week for 1 month) exhibited substantial improvement in the Y maze test and mouse stirring test compared with the APP/PS1 drug-loaded group. Significantly improved spontaneous changes and delayed response behavior in mice (day 27 or 30), and showed model relevance [1] JNK3 inhibitor-4 (30 mg/kg; injected intravenously; single dose; recorded 0- 6h) showed blood-brain barrier permeability in SD tandem with a brain/vessel concentration ratio of 0.02 (26ng/g vs 1084).

Solubility (In Vivo) |
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).

Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
1 mM | 2.0940 mL | 10.4699 mL | 20.9398 mL | |
5 mM | 0.4188 mL | 2.0940 mL | 4.1880 mL | |
10 mM | 0.2094 mL | 1.0470 mL | 2.0940 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.
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.
