ZM734
ZM734 is an orally active and selective NLRP3 inflammasome inhibitor. ZM734 inhibits the secretion of IL-1β. ZM734 alleviates pulmonary inflammation in a mouse model of acute lung injury. ZM734 can be used for the research of inflammatory diseases such as acute lung injury.

Descripciòn
IC50 & Target
[1]|
IL-1β |
In Vitro
ZM734 (0.1-2000 nM; 1 h) potently and selectively inhibits NLRP3 inflammasome activation in mouse bone marrow-derived macrophages (BMDMs), with an IC50 value of 400 nM for IL-1β and 721 nM for IL-18, while exerting no effect on TNF-α, IL-6, AIM2 and NLRC4 pathways[1].
The CC50 of ZM734 in BMDMs is 92.0 μM[1].
ZM734 (0.1-1 μM) inhibits the production of IL-1β in human THP-1 cells[1].
ZM734 (1 μM) inhibits the expression of pro-IL-1β without altering the levels of NLRP3 or pro-caspase-1 in BMDMs stimulated with LPS (HY-D1056) + ATP (HY-B2176), and it acts on the activation stage of the NLRP3 inflammasome[1].

-
Cell Line:BMDMs
-
Concentration:0.1-10 μM; 64.5-2000 nM
-
Incubation Time:1 h (pre-incubation prior to LPS stimulation)
-
Result:Inhibited LPS+ATP-induced IL-1β secretion by 59.1% at 0.1 μM.
Inhibited LPS+ATP-induced IL-1β secretion by 69.5% at 1 μM.
Exhibited dose-dependent inhibition of LPS+ATP-induced IL-1β and IL-18 secretion, with IC50 values of 400 nM and 721 nM, respectively.
Did not significantly inhibit LPS-induced TNF-α or IL-6 secretion at 1 μM and 10 μM.
Significantly reduced IL-1β secretion induced by multiple NLRP3 activators (LPS+ATP, LPS+Nigericin, LPS+MSU).
Showed no significant inhibitory effect on AIM2 or NLRC4 inflammasome-mediated IL-1β secretion.
In Vivo
ZM734 (30-60 mg/kg; p.o.; single dose) exhibits reduced hepatotoxicity in healthy C57BL/6 mice, causing smaller elevations in serum ALT and AST levels than MCC950 at equivalent or higher oral doses[1].

-
Animal Model:C57BL/6 mice (n=6 per group)[1]
-
Dosage:10 mg/kg
-
Administration:i.p.; single dose
-
Result:Significantly alleviated LPS-induced lung pathological injuries, including reductions in inflammatory cell infiltration, intravascular congestion, alveolar wall thickening, and pulmonary interstitial hemorrhage.
Significantly suppressed LPS-induced increases in IL-1β levels in mouse bronchoalveolar lavage fluid, with no significant effect on TNF-α or IL-6 levels.
-
Animal Model:C57BL/6 mice (8 weeks old; equal numbers of males and females; n=6 per group)[1]
-
Dosage:30 mg/kg; 60 mg/kg
-
Administration:p.o.; single dose
-
Result:Induced smaller increases in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels compared to MCC950 at the same 30 mg/kg dose.
Caused ALT and AST levels that remained lower than those induced by MCC950 at 30 mg/kg when administered at 60 mg/kg.
