Doses: 250 mg/ kg Route of Administration: po (oral gavage) Experimental Results: Inhibition of NLRP3 activity, immunopositive pancreatic cell area Dramatically diminished to (21,30 ± compared to the value in the untreated animal group (75,19±7,69% ), respectively (5,44) and (39,31±5,24)%. Promote the correction of pancreatic dysfunction during alloxan-induced diabetes by inhibiting the activation of NLRP3 inflammasome in pancreatic cells. |

Pikamilon has been shown to increase blood flow to the cerebral cortex of conscious rats and rabbits. Increased blood flow was observed with intravenous, intraperitoneal and systemic administration. Topical application of pycamilone significantly dilates pial arterioles. Dilation mainly occurs in arterioles with an initial diameter of 10-20 micrometers. The dilating effect of pycamilone decreases with increasing diameter of pial arterioles. [1]
In rats, seizures were induced by repeated injections of Pikamilon (PTX) (intraperitoneal injection every 30 minutes, with an initial dose of 0.9 mg/kg and subsequent doses of 0.7 mg/kg). Pikamilon (PM) and isopiamilone (IPM) were administered intraperitoneally 30 minutes before PTX injection. Following pre-administrative injection of PM and IPM, epileptiform activity (EFA) recorded from brain structures was classified into two types: one type showed only spike-and-slow-wave discharges (SWD) (61.3%), and the other type showed regular cortical spike-and-wave activity accompanied by transient SWD (38.7%). In the first type of EFA rats, the frequency and duration of SWD were significantly reduced after injection of PM and IPM at a dose of 50 mg/kg. In the second type of EFA rats, even injection of smaller doses (20 mg/kg) of the drugs reduced the intensity of SWD. IPM was more effective as a protective anticonvulsant. [2] |

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).

*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.
