HMGB1-IN-1 (compound 6) displays strong NO inhibitory effect in RAW264.7 cells with IC50 value of 15.9 ± 0.6 μM. HMGB1-IN-1 inhibit the HMGB1/NF-κB/NLRP3 pathway. HMGB1-IN-1 shows good anti-inflammatory activity and good anti-sepsis effects in kidney injury.
HMGB1-IN-1 (compound 6) (0-30 μM, 0-48 h) not only decreases IL-1β and TNF-α levels in RAW264.7 cells and HK-2 cells, but also down-regulates the levels of NLRP3, P-NF-κB p65 and HMGB1 in activated HK-2 cells in a dose-dependent manner[1].
HMGB1-IN-1 (compound 6) (15-30 mg/kg, intraperitoneal injection) shows good anti-inflammatory activity[1].
