产品描述 | Aspirin is an orally active, selective, and irreversible inhibitor of COX-1 and COX-2 with IC₅₀ values of 5 and 210 μg/mL, respectively. It induces apoptosis, inhibits NF-κB activation and platelet prostaglandin synthesis, thereby preventing thrombosis. Additionally, it acts as a histone deacetylase inhibitor that upregulates p21, exhibiting anti-inflammatory, antipyretic, analgesic, and anti-platelet aggregation activities. Aspirin is commonly used to induce gastric ulcer models. |
靶点活性 | COX-1:5 μg/mL, COX-2:210 μg/mL, MDA-MB-231 cells:2 mM, A549 cells:5 mM, PPARα:4.19 μM (EC50) |
体外活性 | 方法: 结直肠癌细胞 SW620、LoVo、RKO 和 DLD-1 用 Aspirin (2 mM) 和 Cisplatin (5-80 µM) 处理 48 h,使用 MTT assay 检测细胞活力。 |
体内活性 | 方法: 为检测体内抗肿瘤活性,将 Aspirin (100 mg/kg,灌胃给药,每天一次) 和 Cisplatin (3 mg/kg,腹腔注射,每三天一次) 给药给携带 LoVo 异种移植物的裸鼠,持续 18 天。 |
细胞实验 | Chondrocytes are isolated from articular cartilage of donors with no articular disease. Unstimulated and interleukin 1 (IL-1) stimulated chondrocytes are used as models to study the effects of drugs on COX-1 and COX-2. Cells are incubated with vehicle or drugs (Asprin); supernatants are removed and the level of prostaglandin E2 (PGE2) in each sample is determined by enzyme immunoassay. IC50s are calculated from the reduction in PGE2 content by different concentrations of the test substance by linear regression analysis[5]. |
