Givinostat (ITF2357) suppresses total LPS-induced IL-1β production robustly compared with the reduction by ITF3056. At 25, 50, and 100 nM, Givinostat reduces IL-1β secretion more than 70%. Givinostat suppresses the production of IL-6 in PBMCs stimulated with TLR agonists as well as the combination of IL-12 plus IL-18. IL-6 secretion decreases to 50% at 50 nM Givinostat, but at 100 and 200 nM, there is no reduction. Givinostat (ITF-2357) inhibits JS-1 cell proliferation in a concentration-dependent manner in the CCK-8 assay. Treatment with Givinostat (ITF-2357) ≥500 nM is associated with significant inhibition of JS-1 cell proliferation. Also, the cell inhibition rate significantly differs between the group cotreated with Givinostat (ITF-2357) ≥250 nM plus LPS and the group without LPS treatment.
Givinostat (ITF2357) at 10 mg/kg is used as a positive control and reduces serum TNFα by 60%. Pretreatment of Givinostat (ITF-2357) starting at 0.1 mg/kg significantly reduces the circulating TNFα by nearly 90%. To achieve a significant increase in serum IL-1β production, a higher dose of LPS is injected (10 mg/kg), and blood is collected after 4 h.
