Product Description

Artemisinin (also known as qinghaosu in Chinese; NSC-369397), discovered by Tu Youyou (2015 Nobel Prize winner in Medicine) team, is a naturally occurring anti-malarial drug isolated from the aerial parts of Artemisia annua L. plants. Artemisinin and its semi-synthetic derivatives are a group of drugs that possess the most rapid action of all current drugs against Plasmodium falciparum malaria.

Biological Activity I Assay Protocols (From Reference)
Targets
Plasmodium
ln Vitro
Artemisinin (3.125-100 μM) concentration-dependently suppresses Aβ25-35 induced cytotoxicity in PC12 cells. Artemisinin (25 μM) suppresses Aβ25-35-induced LDH release, apoptosis and ROS production, attenuates Aβ-induced mitochondrial membrane potential loss and caspase 3/7 activity increase, and stimulates the phosphorylation of ERK1/2 in a time- and concentration-dependent manner in PC12 cell. ERK 1/2 pathway mediates the protect effects of artemisinin in PC12 cells[1]. Artemisinin shows cytotoxic activity in MCF-7/Dox cell line with IC50 of 3.7±0.4 μg/mL after 24 h treatment. Besides, Artemisinin treatment of MCF-7 cells, sensitive and resistant to Dox and DDP, causes a decrease in expression of proteins such as LF, FTH1, and HEP. Artemisinin activates p38 MAPK-kinase cascade regardless of the oxidative stress due to inhibition of VEGF expression and cell migration[2]. Artemisinin (50, 100 or 200 mg) significantly inhibits isoflurane-induced hippocampal neuronal loss, decreases caspase-3-positive cell counts and also cleaves caspase-3 expression, and modulates the expression of apoptosis pathway proteins. Artemisinin modulates JNK/ERK 1/2 signalling and histone acetylation[3]. Artemisinin inhibits HCV replication in a dose-dependent manner with EC50 value of 167±38 µM. Artemisinin and its most potent analogues partially inhibit the in vitro replication of HCV by induction of reactive oxygen species (ROS)[4]. Artemisinin significantly inhibits VSMC proliferation in a dose-dependent manner. Artemisinin (1 mM) for 72 h significantly reduces the expression of proliferating cell nuclear antigen messenger RNA[5].
ln Vivo
Artemisinin (50, 100 or 200 mg/kg b.wt/day, p.o.) prevents isoflurane-induced working memory impairments as observed in T-maze test. Artemisinin enhances spatial navigation and memory of rats exposed to isoflurane. Artemisinin-treated rats exhibit markedly better performance in comparison with isoflurane-alone-exposed rats[3].
Cell Assay
For this purpose, cells are cultivated in 96-well plates in DMEM, supplemented with insulin. The artemisinin, Dox, and DDP are added to media at different concentrations and the cells are cultivated for either 24 or 48 h. For this purpose artemisinin is diluted in 0.01% DMSO in media. After this time, 10 µL of the MTT dye solution (5 mg/mL in phosphate buffer saline) is added to the cells; the cells are incubated at the same conditions for 3 h. After centrifugation (1500 rpm, 5 min) the supernatant is removed. 100 μL of dimethyl sulfoxide is added to each well, to dissolve formazan. The absorption is measured, using a multi-well spectrophotometer at a wavelength of 540 nm.
Animal Protocol
Separate group of rat pups (total rat pups 80; n = 16 per group) is administered artemisinin (50, 100 or 200 mg/kg body weight) via oral gavage, every day from P2 to P21. On P7, the pups are exposed to isoflurane (0.75% in 30% oxygen or air) for 6 h in a temperature-controlled chamber. Animals that are not exposed to anaesthesia nor given artemisinin served as control group, while rats that receive isoflurane alone are grouped as anaesthetic-controls.

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
