- 制备
4-[2-(5-氯-2-甲氧基苯甲酰氨基)乙基]苯磺酰胺的制备可采用水杨酸为起始物料，水杨酸在光照下以氯气氯化，生成5-氯水杨酸，然后以硫酸二甲酯甲基化得5-氯-2-甲氧基苯甲酸，将后者以氯化亚硫酰氯化，得5-氯-2-甲氧基苯甲酰氯，再与苯胺缩合，产物为N-苯乙基-5-氯-2-甲氧基苯甲酰胺，进而以氯磺酸氯磺化、氨水胺化制得该品。
也可以2-甲氧基-5-氯-苯甲酸为原料，先与氯化亚砜、甲醇作用生成2-甲氧基-5-氯-苯甲酸甲酯，然后与苯乙胺缩合，所得酰胺经氯磺化、肼解后得目标产物4-[2-(5-氯-2-甲氧基苯甲酰氨基)乙基]苯磺酰胺。其制备路线图如下：

- 体内研究
NLRP3-IN-2 is well tolerated with no effects on the glucose levels in vivo.
NLRP3-IN-2 (100 mg/kg) treatment in a model of AMI due to ischemia+reperfusion significantly inhibits the activity of inflammasome (caspase-1) in the heart by 90% (P<0.01) and reduced infarct size, measured at pathology (by >40%, P<0.01) and with troponin I levels (by >70%, P<0.01) .
Animal Model:
Experimental acute myocardial infarction (AMI) model in mice.
Dosage:
100 mg/kg.
Administration:
Intraperitoneal administration 30 minutes prior to surgery, then every 6 hours for 3 additional doses.
Result:
Led to a significant >90% reduction in caspase-1 activity (reflective of the formation of an active inflammasome) in the heart tissue measured 24 hours after ischemia.
Led to a significant reduction in the infarct size measured with TTC (>40% reduction) or troponin I levels (>70% reduction) when compared with vehicle alone.
