| ln Vitro |
Laurolitsine has anti - platelet activity in vitro. At a concentration of 300 μM, it can significantly inhibit the aggregation of rabbit platelets induced by arachidonic acid (100 μM) and collagen (10 μg/ml), and slightly inhibit the aggregation induced by adenosine diphosphate (ADP, 20 μM). It may achieve this by inhibiting thromboxane A2 formation [1]
|
| Cell Assay |
Platelet aggregation assay: Rabbit platelets are isolated and incubated with different concentrations of Laurolitsine. Then, add arachidonic acid, collagen or ADP as inducers. Observe and record the platelet aggregation situation through a turbidimetric method. Measure the change of light transmittance, and draw a curve of the relationship between drug concentration and platelet aggregation rate to evaluate the anti - platelet effect of Laurolitsine [1]

| Additional Infomation |
Lauryl alkaloid is an apophene alkaloid. It has been studied for its antiplatelet activity along with other apophene and phenanthrene alkaloids. Its antiplatelet mechanism may be related to the inhibition of thromboxane A2 production, which is one of the key factors leading to platelet aggregation [1]. Lauryl alkaloid is an apophene alkaloid, a compound of noraporphine with hydroxyl groups at positions 2 and 9 and methoxy groups at positions 1 and 10. It was isolated from Litsea glutinosa and Lindera chunii and has activity that inhibits HIV-1 integrase. It is both a metabolite of HIV-1 and an inhibitor of HIV-1 integrase. It belongs to the phenol, aromatic ether and apophene alkaloid class of compounds. It is functionally related to apophene. Lauryl glutinosa alkaloid has been reported to be found in Litsea glutinosa, Lindera chunii and other organisms with relevant data.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
