JT002
Based on 1 Customer Validation
JT002 is an orally active and selective NLRP3 inflammasome assembly inhibitor. JT002 reduces NLRP3-dependent proinflammatory cytokine (such as IL-1β, IL-1α, IL-18) production and pyroptosis. JT002 blocks NLRP3 inflammasome complex formation. JT002 reduces airway hyperresponsiveness and airway neutrophilia in mice. JT002 can be used for the study of a variety of inflammatory diseases, such as Muckle-Wells syndrome (MWS).

Biological Activity
In human peripheral blood mononuclear cells (hPBMCs) treated with Lipopolysaccharides (HY-D1056) (LPS) and activated with ATP (HY-B2176), JT002 shows concentration-dependent inhibition of IL-1α, IL-1β and IL-18 production with mean IC50 values of 3 nM, 4 nM and 4 nM, respectively, with no effect on TNFα production[1].
Under LPS plus Nigericin (HY-127019) stimulating conditions, JT002 inhibits IL-1β production from human, mouse and rat PBMCs with mean IC50 values of 6, 25 and 159 nM, respectively[1].
In human and mouse blood stimulated with LPS plus ATP, JT002 shows concentration-dependent inhibition of IL-1β production with mean IC50 values of 100 nM and 94 nM, respectively[1].
JT002 inhibits pyroptosis in LPS plus nigericin stimulated mouse bone-marrow derived macrophages (mBMDMs) as measured by cellular ATP content, with a mean IC50 value of 7 nM[1].
JT002 blocks canonical NLRP3-dependent IL-1β production activated downstream of ATP, Nigericin, cholesterol crystals (CHC) or monosodium urate (MSU) with mean IC50 values of 5 nM, 23 nM, 2 nM and 3 nM, respectively and inhibits non-canonical induced IL-1β production with a mean IC50 value of 30 nM[1].
JT002 shows no inhibition of IL-1β production after NLRP1, NLRC4 or AIM2 activation at concentrations up to 10 µM[1].
JT002 blocks NLRP3 inflammasome complex formation and downstream pathway activation. JT002 inhibits cellular caspase-1 activity with an IC50 of 8 nM in human PBMCs[1].

JT002 (2.5-25 mg/kg; oral gavage; once daily; from Day 23-29) in ovalbumin (OVA)-sensitized, OVA-challenged, and induced regulatory T cell (iTreg)-transferred CD8a-/- mice (mimicking IL-17-dependent neutrophilic asthma). The 25 mg/kg dose of JT002 significantly reduces airway hyperresponsiveness and airway neutrophilia, decreases submucosal inflammatory cell infiltration, reduces the concentrations of IL-6 and IL-17 in bronchoalveolar lavage fluid, and increases the INFγ concentration. The 2.5 mg/kg dose of JT002 has no significant effect[1].
JT002 (2.5 mg/kg and 25 mg/kg; oral gavage; once daily; 4 days) in female C57BL6/J mice (a model of ozone - induced neutrophilic asthma). The 25 mg/kg dose of JT002 prevents ozone-induced airway hyperresponsiveness, significantly reduces the number of neutrophils in bronchoalveolar lavage fluid, and reduces airway epithelial desquamation. The 2.5 mg/kg dose of JT002 has no significant effect[1].
