Description générale

Acetylsalicylic acid is an organic compound commonly referred to as aspirin. It works by blocking the production of compounds in the body that cause pain, swelling, and fever. Acetylsalicylic acid also serves a vital function in preventing blood clots from forming in the arteries. In research, acetylsalicylic acid is studied for its role in oxidative stress, and in cancer research as a biomarker.

Actions biochimiques/physiologiques

Blocks the production of prostaglandins by inhibiting cyclooxygenase (prostaglandin H synthase), with greater selectivity toward the COX-1 isoform. The antithrombotic effect is due to the inhibition of COX-1 in platelets that blocks thromboxane production and platelet aggregation. Chemopreventive against colorectal and other solid tumors.

Treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with various side effects, including cardiovascular and hepatic disorders. Studies suggest that mitochondrial damage and oxidative stress are important mediators of toxicity, yet the underlying mechanisms are poorly understood. In this study

Aspirin use reduces the risk of colorectal carcinoma. Experimental evidence implicates a role of RAF kinases in up-regulation of prostaglandin-endoperoxide synthase 2 (PTGS2, cyclooxygenase 2), suggesting that BRAF-mutant colonic cells might be less sensitive to the antitumor effects of aspirin
