CORM-3, a carbon monoxide-releasing molecule, attenuates NF-κB p65 nuclear translocation, reduces ROS generation and enhances intracellular glutathione and superoxide dismutase levels. CORM-3 reduces NLRP3 inflammasome activation.
体外研究
CORM-3 suppresses caspase-1 activation and the secretion of interleukin (IL)-1β and IL-18 in macrophages in response to lipopolysaccharide (LPS) and ATP. CORM-3 inhibits the oligomerization of the adaptor protein apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), which is required for NLRP3-dependent caspase-1 activation.
体内研究
CORM-3 (4 mg/kg, ip) reduces NLRP3 inflammasome activation and inhibits hyperglycemia-induced inflammation in mice.
Animal Model:
WT mice (C57BL/6J male, 8e10 weeks old).
Dosage:
4 mg/kg.
Administration:
IP for 3 h before i.p. injection of E. coli LPS (10 mg/kg), and IP injection after 7-day-treatment of S0130.
Result:
Resulted in significantly lower plasma levels of IL-1β and IL-18 in response to LPS challenge in vivo in WT mice relative to that in vehicle-treated control mice, whereas TNF-a levels were unchanged.
Had lower expression of cleaved caspase-1 and cleaved IL-1b in response to ATP and nigericin, relative to vehicle control, whereas the expression of procaspase-1 and pro-IL-1β expression was unchanged.
