生物活性 |
NLRP3-IN-10 is a potent NLRP3 inhibitor, inhibits IL-1β release with an IC50 value of 251.1 nM. NLRP3-IN-10 suppresses NLRP3 inflammasome activation by attenuating ASC speck formation.

体外研究 |
NLRP3-IN-10 (compound 14c) (0.4, 1.6, 6.4 μM; 40 min) exerts remarkable inhibitory activity on NLRP3 inflammasome activation induced by LPS-MSU (12 h) in THP-1 cells in a dose-dependent manner.
NLRP3-IN-10 (0.1-6.4 μM; 1.5 h) shows no cytotoxicity against THP-1 cells and (0.1, and 0.4 μM; 40 min) avoids Nigericin (HY-127019)-induced pyroptosis.
NLRP3-IN-10 (0.1, 0.2, and 0.4 μM; 40 min) reduces the processing of caspase-1 p20 and IL-1β, in supernatants in THP-1 cells in a dose-dependent manner.
NLRP3-IN-10 (3 μM and 5 μM; 40 min) decreases LPS-induced THF-α, and (0.2 μM and 0.8 μM; 40 min) reduces the rate of THP-1 cells with ASC specks, indicating ASC oligomerization interruptionsup>.
NLRP3 inflammasome is regarded as a two-step process, including priming and action. NLRP3-IN-10 (1, 10, and 100 μM; 40 min) suppresses LPS-induced NLRP3 priming through directly interacting with NLRP3.

NLRP3-IN-10 (compound 14c) (10 mg/kg; i.v.; single dose) reduces peritoneal neutrophil influx in mice and IL-1β in the spleen in the MSU-induced peritonitis in LPS-primed mouse model.
NLRP3-IN-10 (10, 30, 90 mg/kg; p.o.; single dose) exhibits extremely low exposure (14.6−23.53 μg·h/L), poor bioavailability (2.47−13.79%), and high plasma clearance (2201.58−5551.12 L/h/kg) after different doses for oral administration.
