邻乙酰水杨酸抑制剂Acetylsalicylic acid is a potent and selective inhibitor of COX with various pharmacological activities, such as anti-inflammation and pain relief. Acetylsalicylic acid is a histone deacetylase inhibitors to up-regulate cell cycle arrest protein p21, which can suppresses ovarian Y cells harboring COX-1. Acetylsalicylic acid also inhibits the expression of COX-2 in HUVEC and neonatal rat ventricular cardiomyocytes, and then reduce PG production and the down-regulation of ERK and NF-KB, respectively.
