Product Introduction

Bioactivity
Description
Esonarimod (KE-298) is an antirheumatic drug designed to alleviate symptoms associated with rheumatoid arthritis.
In vitro
The IC50 of Esonarimod is 117.5 μg/mL. In RAW264.7 cells, Esonarimod (KE-298) (10 to 300 μg/mL) suppresses the production of NO in a dose-dependent manner.
In vivo
After repeated oral administration of Esonarimod (14C-KE-298), the radioactivity rapidly decreases with no accumulation observed.
Kinase Assay
To test enzyme activity of NOS, the lysate from RAW264.7 cells (a protein concentration of 37.5 μg/200 μL) is incubated for 3 h at 37°C with 100 mM of L-arginine in the presence of Esonarimod (KE-298) and the conversion of L-arginine to nitrite is monitored.
Cell Research
For in vitro experiment, Esonarimod (KE-298) is dissolved in ethanol and diluted with culture medium or distilled water.RAW264.7 cells are used in this study. For NO production, RAW264.7 cells [2×105/0.2 mL of RPMI-1640 supplemented by 10% heat inactivated fetal bovine serum (FBS), penicillin G (100 U/mL), and streptomycin (100 μg/mL)] are stimulated with 100 ng/mL of Escherichia coli 026:B6 lipopolysaccharide in the presence of Esonarimod (KE-298) (0, 10, 30, 100, 200, 300 μg/mL) in 96 well plates and incubated 24 h at 37°C in an atmosphere of 5% CO2 in air. After incubation, the supernatants are collected and assayed for nitrite (NO2-) instead of NO[1].
Animal Research
Seven-week-old male Wistar rats is administered Esonarimod (5 mg/kg once daily) orally by gastric intubation.

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
