Aspirin calcium
Based on 39 publication(s) in Google Scholar
Aspirin calcium is an orally active, potent and irreversible inhibitor of cyclooxygenase COX-1 and COX-2, with IC50 values of 5 and 210 μg/mL, respectively. Aspirin calcium induces apoptosis. Aspirin calcium inhibits the activation of NF-κB. Aspirin calcium also inhibits platelet prostaglandin synthetase, and can prevent coronary artery and cerebrovascular thrombosis.

Biological Activity
Aspirin calcium inhibits COX-1 and COX-2 in human articular chondrocytes, with IC50 values of 3.57 μM and 29.3 μM, respectively[2].
Aspirin calcium acetylates serine-530 of COX-1, thereby blocking thromboxane A synthesis in platelets and reducing platelet aggregation[3].
Aspirin calcium inhibits COX-2 protein expression through interference with binding of CCAAT/enhancer binding protein beta (C/EBPbeta) to its cognate site on COX-2 promoter/enhancer[3].
Aspirin calcium inhibits NF-κB-dependent transcription from the lgκ enhancer and the human immunodeficiency virus (HIV) long terminal repeat (LTR) in transfected T cells[4].
Aspirin calcium induces apoptosis by the activation of caspases, the activation of p38 MAP kinase, release of mitochondrial cytochrome c, and activation of the ceramide pathway[6].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
Aspirin (5-150 mg/kg, PO, once) calcium shows significant antipyretic activity in adult yeast-fevered male rats[7].
Aspirin calcium can be used to induce gastrointestinal ulcer models[8].
Administration: 500 mg/kg • oral • single dose
Resulted in a decrease in the mucosal thickness.
Induced ulcer without COX-1 reaction.

Animal Model:Male albino Charles River rats (200-250 g, 8 animals/group, fever was induced by 20 mL/kg of a 20% aqueous suspension of brewer’s yeast which was injected SC in the back below the nape of the neck)[7]
-
Dosage:5, 25, 50, 100 and 150 mg/kg
-
Administration:PO, once
-
Result:Produced a statistically significant decrease of 0.23°C at 15 min post-drug at the dose of 150 mg/kg. Antipyretic effect gradually increased in magnitude until a peak effect of 1.96 °C was reached at 120 min post-drug. The ED50 of aspirin was found to be 10.3 mg/kg with confidence limits of 1.8-23.0 mg/kg. The antipyretic response to aspirin is dependent on the dose of the compound administered.
