Biological Activity


Targets IC50: 1.02 Μm (hAChE)[1]. IC50: 7.03 μM (hBChE)[1].
ln Vitro NLRP3-IN-33 (12o) (1-30 μM; 24 h) had no significant cytotoxic effect in PC-12 cells[1]. NLRP3-IN-33 has antioxidant activity and can inhibit the production of free radicals with an IC50 value of 6.19 μM. 12o (1-20 μM; 24 h) effectively alleviated oxidative stress induced by H2O2 (600 μM; 24 h) in PC-1 cells and had a neuroprotective effect[1]. NLRP3-IN-33 (1-20 μM; 24 h) also inhibited the activation of NLRP3 inflammasome in PC-1 cells and reduced mitochondrial-induced reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) damage caused by LPS (1 μg/mL) and ATP (5 mM) in HMC-3 cells[1].
ln Vivo NLRP3-IN-33 (12o) (0.05-0.02 mg/mL) can more effectively reduce mitochondrial and cellular oxidative stress in the Drosophila AD model at a low dose (0.05 mg/mL) [1]. LRP3-IN-33 (5 mg/kg; intraperitoneal injection; once a day for 22 consecutive days) can improve memory impairment and cognitive impairment in the Scopolamine (HY-N0296) (1.4 mg/kg; intraperitoneal injection; once a day for 5 consecutive days)-induced AD mouse model [1].
Cell Assay Western Blot Analysis[1]
Cell Types: HMC-3 Concentration: 12.5 μM, 25 μM
Incubation Duration: 24 h
Experimental Results: Inhibited the NLRP3 inflammasome activation and caspase-1 release. Significantly decreased the expression of NF-κB and NLRP3 proteins.
Animal Protocol Animal/Disease Models:Alzheimer's disease (AD) fractional model[1]
Doses: 1 mg/kg, 5 mg/kg
Route of Administration: Intraperitoneal injection (i.p.); Once daily for 22 days. Received scopolamine (HY-N0296) (1.4 mg/kg; i.p.; once daily for 5 days) on the last 5 days of the experiment (day 18 to day 22).
Experimental Results: Significantly shortened escape latency time as compared to the scopolamine-treated group.

Solubility Data


Solubility (In Vitro) May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples
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
(e.g. IP/IV/IM/SC)
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution 50 μL Tween 80 850 μL Saline)
*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)]
*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.

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

Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose
Oral Formulation 6: Mixing with food powders

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (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.
