6、AL ACTIVITY物活性 Aspirin選擇性和不可逆的 COX-1 和 COX-2 抑制劑,IC50 分別為5,210 g/mL。IC & Target COX-1 COX-227.75 M (IC50) 1.17 mM (IC50)體外研究 Aspirin and other non-steroid anti-inflammatory drugs inhibit the activity of cyclooxygenase (COX) which leads to theformation of prostaglandins (PGs) that cause inflammation,

7、 swelling, pain and fever2. Aspirin acetylates serine-530 ofcyclooxygenase-1 (COX-1), thereby blocking thromboxane A synthesis in platelets and reducing platelet aggregation.This mechanism of action accounts for the effect of aspirin on prevention of coronary artery and cerebrovascularthrombosis. As

8、pirin is less effective in inhibiting COX-2 activity. Aspirin and salicylate inhibit COX-2 protein expressionthrough interference with binding of CCAAT/enhancer binding protein beta (C/EBPbeta) to its cognate site on COX-2promoter/enhancer3. Aspirin inhibits the activation of NF-B. This inhibition p

Aspirin also inhibits NF-B-dependent transcription fromthe lg enhancer and the human immunodeficiency virus (HIV) long terminal repeat (LTR) in transfected T cells4.Aspirin inhibits COX-1 and COX-2 with
