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:

NLRP3 inflammasome
() |
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. |
