COX-2 20 μM (IC50) |
MIF 6.81 μM (IC50) |
Iguratimod (T-614) is an antirheumatic agent, acts as an inhibitor of COX-2, with an IC50 of 20 μM (7.7 μg/mL), but shows no effect on COX-1. Iguratimod (0.1, 1, 10 μg/mL) inhibits bradykinin-stimulated PGE2 release from fibroblasts. Iguratimod suppresses the COX activity from bradykinin stimulated fibroblasts in a concentration-dependent manner, with an IC50 of 48 μg/mL. Iguratimod (10 and 30 μg/mL) also dose-dependently inhibits COX-2 mRNA levels[1]. In addition, Iguratimod potently inhibits macrophage migration inhibitory factor (MIF) with an IC50 of 6.81 μM. Iguratimod is synergetic with glucocorticoids in vitro[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (6.68 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Protocol
Briefly, human Raji B cells are plated at a density of 0.5 × 104 cells/well in a 96-well plate and synchronized by incubation for 24 h in RPMI 1640 medium supplemented with 0.1-0.5% FBS. Synchronized cells are pretreated with Iguratimod or vehicle for 30 min prior to stimulation with macrophage migration inhibitory factor (MIF) for 24 h. At 20 h BrdU is added to cells and quantified using a BrdU Cell proliferation assay kit[3].

Mice[3]
Endotoxemia is induced by intraperitoneal injection of LPS from E. coli O111:B4. In BALB/c animals, 5 mg/kg LPS is used as a lethal dose for survival experiments; animals are treated with Iguratimod (20 mg/kg i.p.) 0.5 h prior to LPS, 6 h after LPS, and then once daily for 3 days and monitored for survival over 2 weeks. In C57BL/6 animals, 20 mg/kg LPS is used as non-lethal dose for plasma cytokine experiments; animals are pretreated with Iguratimod (20 mg/kg i.p.) twice, one dose each at 2 and 0.5 h prior to LPS administration, and euthanized at 90 min post-LPS by CO2 asphyxiation with cervical dislocation. Blood is collected by cardiac puncture and allowed to clot 20 min at room temperature and 20 min at 4°C; sera are isolated by centrifugation at 300 × g for 10 min and stored at −20°C for further analysis by TNFα ELISA (1:3 dilution)[3].
