At 30 μM, Tau Aggregation and Neuroinflammation-IN-1 (Compound 30) (0–40 μM) decreases the survival rate of SH-SY5Y cells; at high doses, it does not appear to be hepatotoxic to LO2 cells, and at 20 μM, it has no discernible hepatotoxicity to BV2 cells. In LPS-stimulated BV2 cells, tau aggregation and neuroinflammation-IN-1 (2.5, 5 and 10 μM; 24 hours) reduces NO release by 41% while maintaining the anti-inflammatory action of usnate [1].

In rats with OA-induced memory impairment, tau aggregation and neuroinflammation-IN-1 (5 and 10 mg/kg; for 14 days) markedly enhanced conventional reference spatial memory and cognitive functions [1].

| Cell Assay |
Cytotoxicity assay
Cell Types: SH-SY5Y, LO2 and BV-2 cells [1] Tested Concentrations: 0, 10, 20, 30 and 40 μM Incubation Duration: 24 hrs (hours) Experimental Results: The survival rate of SH-SY5Y cells was diminished at 30 μM, Even at high concentrations (up to 40 μM), there was no obvious liver toxicity to LO2 cells and no effect on BV2 cell viability at 20 μM. |
| Animal Protocol |
Animal/Disease Models: Male SD rat (250-270 g; OA microinjected into the right dorsal hippocampus) [1]
Doses: 5 and 10 mg/kg Route of Administration: intraperitoneal (ip) injection; 7 days after OA injection Continuing IP injection for 7 days resulted in significant improvements in conventional reference spatial memory and cognitive abilities in rats. |

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).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.1718 mL | 10.8592 mL | 21.7184 mL | |
| 5 mM | 0.4344 mL | 2.1718 mL | 4.3437 mL | |
| 10 mM | 0.2172 mL | 1.0859 mL | 2.1718 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.
