Dapansutrile 是一种口服有效的选择性 NLRP3 炎症小体抑制剂。Dapansutrile 具有抗炎活性,能够降低免疫因子水平。Dapansutrile 可用于炎性疾病的研究。
生物活性 | Dapansutrile is a potent, orally active and selectiveNLRP3inflammasomeinhibitor. Dapansutrile has anti-inflammatory activity and decreases immune factor levels. Dapansutrile can be used for research of inflammatory diseases[1][2]. |
体内研究 (In Vivo) | Dapansutrile (3.75 g/kg; p.o.; daily, for 22 d) ameliorates neurological decline and nervous tissue damage in experimental autoimmune encephalomyelitis (EAE) mice[1]. Dapansutrile (3.75 g/kg; p.o.; daily, for 22 d) attenuates the protein levels of pro-inflammatory cytokines in the spinal cord of experimental autoimmune encephalomyelitis (EAE) mice[1]. Dapansutrile (6-600 mg/kg; i.p.; once; male ICR (CD1) mice) reduces infarct size and reduces caspase-1 activity in the heart[2]. Dapansutrile (6-600 mg/kg; i.p.; once, for 24 hours and 7 days; mice subjected to acute myocardial infarction) preserves cardiac function following myocardial ischemia-reperfusion injury[2].
Animal Model: | EAE-induced female adult C57BL/6 (8–10 weeks old)[1] | Dosage: | 3.75 g/kg | Administration: | Oral administration; daily, for 22 days | Result: | Ameliorated the neurological deficits of EAE disease. Reduced the levels of IL-1β, L-18 , TNFα, CXCL-1 and IL-6. Showed ~2-fold reduction in the infiltration of T cells (CD45+, CD3+). Reduced the accumulation macrophages (CD45high, CD11b+, F4/80+), microglia (CD45low, CD11b+), and other cells (CD45+, CD11b-, CD3-, CD24+). |
Animal Model: | Male ICR (CD1) mice (8-12 weeks old)[2] | Dosage: | 6, 60, and 600 mg/kg | Administration: | Intraperitoneal injection; once | Result: | Reduced infarct size in a dose-dependent manner. |
Animal Model: | Mice subjected to acute myocardial infarction (AMI)[2] | Dosage: | 6, 60, and 600 mg/kg | Administration: | Intraperitoneal injection; once, for 24 hours and 7 days | Result: | Preserved left ventricular (LV) systolic function at 24 hours. Increased in cardiac function at 7 days of reperfusion when compared with the control mice. |
