Aspirin (Acetylsalicylic acid) 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 induces apoptosis. Aspirin inhibits the activation of NF-κB. Aspirin also inhibits platelet prostaglandin synthetase, and can prevent coronary artery and cerebrovascular thrombosis.

In Vitro

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

In Vivo

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.

Animal Model:

Albino male mice ^[8]
Dosage:

500 mg/kg, single dose
Administration:

oral
Result:

Caused erosion of the surface epithelial cells.
Resulted in a decrease in the mucosal thickness.
Induced ulcer without COX-1 reaction.

Induced Disease Models

Note:
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 lithium (5-150 mg/kg, PO, once) shows significant antipyretic activity in adult yeast-fevered male rats^[7].
Aspirin can be used to induce gastrointestinal ulcer models^[8].

Induction of gastric Ulcer Model^[8]

Background

Aspirin inhibits the synthesis of endogenous prostaglandins (PGs) in animals. Aspirin can also lyse mucosal epithelial cells phospholipids, resulting in increased mucosal permeability.

Specific Modeling Methods

Mice: Albino • male • 6-week-old
Administration: 500 mg/kg • oral • single dose

Modeling Indicators

Behavior Observation: Caused erosion of the surface epithelial cell.
Resulted in a decrease in the mucosal thickness.
Induced ulcer without COX-1 reaction.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (13.88 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (13.88 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (13.88 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: Saline

Solubility: 5 mg/mL (27.75 mM); Clear solution; Need ultrasonic

Protocol 2

Add each solvent one by one: 50% PEG300 50% Saline

Solubility: 5 mg/mL (27.75 mM); Clear solution; Need ultrasonic

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
