Cell experiment: |
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]. |

Aspirin (Acetylsalicylic acid) is a potent and selective inhibitor of cyclooxygenase (COX) with a broad range of pharmacological activities including anti-inflammation and pain relief. Multiple studies have accumulated sufficient evidence to establish the association between the use of aspirin and a reduced risk of cancers including prostate cancer, breast cancer, colorectal cancer, endometrial cancer, and ovarian cancer. Aspirin suppresses ovarian cancer cells harboring COX-1 by acting as histone deacetylase inhibitors to up-regulate cell cycle arrest protein p21. Aspirin also inhibits the expression of COX-2 in human umbilical vein endothelial cells and neonatal rat ventricular cardiomyocytes resulting in reduced PG production and the down-regulation of ERK and NF-KB respectively.

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
