    Aspirin lithium purchased from MCE. Usage Cited in: Cell Death Dis. 2018 Aug 28;9(9):847.  [Abstract]

    HIPK2 expression is upregulated by treatments with 5 μM Resveratrol, 30 μM Aspirin, 10 μM Vitamin E, and 15 μM Ursolic acid for another 16 h after the LPS treatment, as analysed by western blotting.

    生物活性

    Aspirin (Acetylsalicylic Acid) lithium 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 lithium induces apoptosis. Aspirin lithium inhibits the activation of NF-κB. Aspirin lithium also inhibits platelet prostaglandin synthetase, and can prevent coronary artery and cerebrovascular thrombosis[1][2][3][4][5][6].

    COX-2

     

    体外研究
    (In Vitro)

    Aspirin lithium inhibits COX-1 and COX-2 in human articular chondrocytes, with IC50 values of 3.57 μM and 29.3 μM, respectively[2].
    Aspirin lithium acetylates serine-530 of COX-1, thereby blocking thromboxane A synthesis in platelets and reducing platelet aggregation[3].
    Aspirin lithium 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 lithium 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 lithium 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].

    体内研究
    (In Vivo)

    Aspirin lithium (5-150 mg/kg, PO, once) shows significant antipyretic activity in adult yeast-fevered male rats[7].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    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 ℃ 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 ℃ 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.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
