B022 is a potent and selective inhibitor of NF-κB-inducing kinase (NIK) with an IC50 value of 15.1nM [1]. B022 can prevent fat formation and inhibit the non-classical NF-κB signaling pathway, and reduce the phosphorylation level of RelA in the cytoplasm[2]. B022 has been widely used to inhibit the production of nitric oxide and alleviate liver damage[3].
In vitro, B022 treatment (20μM) for 48 hours significantly inhibited LTα1/β2-stimulated nuclear translocation of RelB and p52 in SNU-1196 cells[4]. Treatment with 10μM B022 for 16 hours significantly inhibited H2O2-induced cell death in INS-1 832/13 cells, and reversed the inhibitory effect of NIK on insulin secretion-related genes (such as Insulin1/2, Pdx-1, and Neurod1)[5].
In vivo, B022 was injected into the tail vein every 3 hours at the 25μg/kg dose for a total of 9 hours, which could alleviate the acute liver inflammation and damage induced by CCl4 in mice[6]. Intraperitoneal injection of 30mg/kg dose of B022 once a day for 10 consecutive days can alleviate the clinical symptoms of experimental autoimmune myasthenia gravis (EAMG) rats, reduce serum antibody levels, and improve the morphological changes at the neuromuscular junction and complement deposition[7].

Protocol
| Cell experiment [1]: | |
|
Cell lines |
INS-1 832/13 cells |
|
Preparation Method |
INS-1 832/13 cells were cultured at 37°C and 5% CO2 in RPMI-1640 medium supplemented with 10% fetal bovine serum (FBS) and 50mM β-mercaptoethanol. INS-1 832/13 cells were treated with H2O2 (50μM) in the presence of B022 at different doses (0, 1, 5, and 10μM) for 16h and cell viability was measured. |
|
Reaction Conditions |
0, 1, 5, and 10μM; 16h |
|
Applications |
B022 treatment significantly inhibited H2O2-induced cell death in INS-1 832/13 cells in a concentration-dependent manner. |
| Animal experiment [2]: | |
|
Animal models |
Lewis rats |
|
Preparation Method |
Female Lewis rats (6-8 weeks old) weighing 160-180g were housed in temperature (23±2°C) and light-controlled (12:12-hour light-dark cycle) animal care facility with food and tap water ad libitum. The rats were provided with standard rat chow and water. The EAMG rat model was induced with rat AChR97-116 peptide (DGDFAIVKFTKVLLDYTGHI). The rats were immunized subcutaneously at the tail base with a total 200μl emulsion containing 75μg of rat AChR97-116 peptide in phosphate buffer saline emulsified in an equal volume of complete Freund’s adjuvant containing 1mg mycobacterium tuberculosis strain H37RA. Then, the rats were boosted on day 30 with the same dose of AChR97-116 peptide in incomplete Freund’s adjuvant. After the second immunization, clinical scores were assessed every day, and then we selected ongoing EAMG rats with onset clinical scores of 1-1.5 for therapeutic experiments. EAMG rats in the B022 group were intraperitoneally given 30mg/kg B022 for 10 days and the EAMG model group was injected with an equal volume of cosolvent. |
|
Dosage form |
30mg/kg/day for 10 days; i.p. |
|
Applications |
B022 treatment alleviated the clinical symptoms of EAMG rats and exhibited protective consequences in the EAMG rat model. |
