CORM-3 是一种 CO 释放分子,能减弱NF-κB p65的核异位,减少 ROS 的生成,并提高细胞内谷胱甘肽和超氧化物歧化酶的水平。CORM-3 可减少NLRP3炎症小体的激活
生物活性 | CORM-3, a carbon monoxide-releasing molecule, attenuatesNF-κBp65nuclear translocation, reduces ROS generation and enhances intracellular glutathione and superoxide dismutase levels. CORM-3 reducesNLRP3inflammasome activation[1][2][3]. |
IC50& Target | |
体外研究 (In Vitro) | 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[2].

体内研究 (In Vivo) | CORM-3 (4 mg/kg, ip) reduces NLRP3 inflammasome activation and inhibits hyperglycemia-induced inflammation in mice[2].
Animal Model: | WT mice (C57BL/6J male, 8e10 weeks old)[2]. | Dosage: | 4 mg/kg. | Administration: | IP for 3 h before i.p. injection ofE. coliLPS (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.
