What is Artemisinin?
Isolated from the plant Artemisia annua, or sweet wormwood, artemisinin, and its derivatives are powerful medicines known for their ability to swiftly reduce the number of Plasmodium parasites in the blood of patients with malaria. Artemisinin-based combination therapies (ACTs) are recommended by WHO as the first-line treatment for uncomplicated P.
What Is Artemisinin Used For
Against Malaria
Artemisinin is the most popular specific antimalarial drug after pyrimidine, chloroquine, and primaquine. Especially for cerebral malaria and chloroquine-resistant malaria, artemisinin has the characteristics of quick-acting and low toxicity. Its anti-malarial mechanism mainly lies in the formation of free radicals through the activation of artemisinin and the binding of free radicals with Plasmodium proteins, acting on the membrane structure of Plasmodium, destroying its vesicles, nuclear membranes, and plasma membranes, swelling of mitochondria, exfoliation of inner and outer membranes, thus destroying the cell structure and function of Plasmodium and also destroying the chromatin in the nucleus. To a certain extent. Artemisinin also significantly reduced the intake of isoleucine by Plasmodium, thus inhibiting the synthesis of proteins.
Anti-tumor
The anti-tumor effect of artemisinin has been gradually discovered. Artemisinin can cause the apoptosis of breast cancer cells, liver cancer cells, cervical cancer cells, and other cancer cells, and has a significant inhibitory effect on the growth of cancer cells. The anti-tumor effect of artemisinin and its derivatives is mainly achieved by inducing cell apoptosis. It has been found that artemisinin kills cancer cells by inducing cell apoptosis. Dihydroartemisinin can play a selective cytotoxic role by increasing reactive oxygen species, thereby inhibiting the activation of hypoxia-induced related factors. Artemisinin also inhibits human colorectal cancer cells in a dose-dependent manner. It has been found that artesunate inhibits the proliferation and promotes apoptosis of human colorectal cancer cells in a dose-dependent manner. Mitochondria are amplifiers and receptors of cell apoptosis, which regulate and control the metabolic activities of cells. Mitochondrial membrane potential induces cell apoptosis. Artemisinin acts on the cell membrane of leukemia cells, changes the permeability of the cell membrane, and increases the concentration of intracellular calcium ions, which not only activates calpain and makes it swell and die, but also promotes the release of apoptotic substances and accelerates apoptosis.
Immunoregulation
It was found that artemisinin and its derivatives could inhibit T lymphocyte mitogen and induce splenic lymphocyte proliferation in mice without causing cytotoxicity. This finding has a good reference value for the treatment of autoimmune diseases mediated by T lymphocyte. Artemisinin can enhance the non-specific immunity and increase the total complement activity of mice serum. Dihydroartemisinin can directly inhibit the proliferation of B lymphocyte, thereby reducing the secretion of autoantibody by B lymphocyte, alleviating humoral immune response, inhibiting humoral immunity to some extent, and reducing the formation of the immune complex.
Antifungal activity of artemisinin
The antifungal effect of artemisinin also makes artemisinin exhibit certain antifungal activities. The study confirmed that artemisinin residue powder and water decoction had a strong bacteriostatic effect on anthrax, Staphylococcus epidermidis, catarrhalis, and diphtheria bacilli, and also had a certain bacteriostatic effect on tuberculosis bacilli, Pseudomonas aeruginosa, Staphylococcus aureus, and dysentery bacilli.
Other applications of artemisinin
Artemisinin can also be used with Cordyceps Sinensis in the clinic, which can inhibit the recurrence of lupus nephritis and protect the kidney. Its anti-fibrosis effect can significantly reduce the degree of pulmonary fibrosis and has a good practical prospect for the prevention and treatment of scars.
About Artemisinin and its Effectiveness
In the 19th century, this remedy was commonly prescribed for malaria and hemorrhoids. During the 1970s, the active ingredient, qinghaosu, was isolated from the artemisinin plant, and the compound became known as artemisinin. Today, there are many derivatives of artemisinin, including artemether and artemisinin artesunate, which are used in malaria treatment.
Artemisinin is very effective against all the malaria-causing protozoan organisms which are present in the genus Plasmodium. Particularly, this drug is useful in the treatment of infections involving multidrug-resistant P. falciparum and infections involving the chloroquine-resistant parasites, which is the deadliest of malaria protozoans.
The artemisinin targets the organisms of Plasmodium in the schizont stage of development. Schizonts that mature from sporozoites, which is the form of parasite transmitted to humans in the Anopheles mosquitoes saliva-contain insoluble iron known as hemozoin. Hemozoin can be formed within the schizonts because they feed on hemoglobin present in the cytoplasm of red blood cells of the human. Artemisinin has a peroxide group, which reacts with hemozoin, and this reaction can be suspected to result in the radical production that attacks the parasite proteins, thereby killing organisms.
Antitumour Properties Of Artemisinins
Since the late 1980s, anticancer properties of artemisinins have been assayed in vitro. After more detailed studies, artemisinins such as artesunate were found to be active against a variety of unrelated tumour cells lines, from the most common types such as colon, breast and lung cancers to leukaemias and pancreatic cancer. Studies have also identified potential general mechanisms such as normalization of the upregulated Wnt/β-catenin pathway in colorectal cancer. Other pathways for anticancer activity include inhibition of enhanced angiogenesis associated with tumours. Artemisinins inhibit proliferation, migration and tube formation of human umbilical vein endothelial cells (HUVEC), inhibit vascular endothelial growth factor (VEGF) binding to surface receptors on HUVEC and reduce expression of VEGF receptors Flt-1 and KDR/flk-1 on HUVECs. In cancer cells, artemisinins reduce expression of the VEGF receptor KDR/flk-1 in tumour and endothelial cells and slow growth of human ovarian cancer HO-8910 xenografts in nude mice. HUVEC apoptosis by artesunate is associated with downregulation of Bcl-2 (B-cell leukemia/lymphoma 2) and upregulation of BAX (Bcl-2-associated X protein).
MRNA expression of 30 out of 90 angiogenesis-related genes correlated significantly with the cellular response to artemisinins. In this microarray panel, there were many fundamental angiogenic regulators encoded by genes such as VEGFC, fibroblast growth factor-2 (FGF2), matrix metalloproteinase-9 (MMP9), thrombospondin-1 (THBS1) and hypoxia-inducing factor α (HIF1A). The fact that sensitivity and resistance of tumour cells can be predicted by mRNA expression levels of angiogenesis-related genes indicates that artemisinins reveal their antitumour effects, at least in part, by inhibition of tumour angiogenesis. Overexpression of enzymes associated with modulation of oxidative stress such as glutamylcysteine synthetase, glutathione S-transferases and the endothelial growth factor receptor reduce susceptibility of tumour cells to artemisinins. Importantly, overexpression of genes encoding transporters that mediate drug resistance (e.g. multidrug resistance gene 1, multidrug resistance associated protein 1 and breast cancer resistance protein), dihydrofolate reductase and ribonucleotide reductase, which also confer resistance to established antitumour drugs, do not affect susceptibility, indicating that artemisinins function in different ways to classical cancer chemotherapeutic agents. These in vitro studies have also shown that for some cancer lines, delivery of iron, for example by the use of holotransferrin, enhances the anticancer properties of artemisinins.
Should artemisinins remain relegated to the large category of compounds that have interesting in vitro properties against cancers but have not been studied sufficiently to warrant more extensive clinical studies? First, artesunate is a cheap, safe, easily administered and orally bioavailable compound that acts at targets different to those of many current cancer chemotherapeutic agents and is unlikely to interact adversely with existing anticancer interventions (P. Folb, personal communication). Second, study of an animal model carrying a human colorectal cancer cell line confirms that artesunate has independent antitumour activity and can shrink primary tumours and reduce the risk of hepatic metastases developing. Additionally, human studies of individual cases , in addition to a recently published Phase II study of lung cancer , support rapid implementation of studies of artesunate as a primary or adjunct antitumour intervention, particularly for colorectal cancers and for leukaemia.
Isolation and Extraction of Artemisinin
Artemisinin is obtained from the leaves of the plant and the isolation and extraction process is as follows:
Extraction of Artemisinin
Drying and solvent extraction: A. annua leaves are dried and soaked in organic solvents such as hexane or ethanol.
Filtration and evaporation: After the solvent extraction, the obtained solution is filtered and evaporated so as to concentrate it.
Purification: To purify artemisinin, liquid-liquid extraction method is often used, in which artiminisin is partitioned between two immiscible solvents, and isolating it from other plant constituents.
Isolation & Purification of Artemisinin
After extraction, the compound is purified using chromatographic techniques.
High Performance Liquid Chromatography (HPLC) is used because of its high resolution and efficiency.
Some cases involve flash chromatography or thin-layer chromatography (TLC) for purification.
The final product is recrystallized using techniques that further purify artemisinin. It is done by dissolving the product in a suitable solvent, allowing it to crystallize further under controlled conditions.
This ensures that the final product is of high purity and can be used for pharmaceutical applications.
Key Points Of Artemisinin Resistance
Malaria, caused by Plasmodium spp., remains a tremendous disease burden worldwide, causing nearly one million deaths and 250 million cases of disease.
Artemisinin and artemisinin derivatives are effective antimalarials, especially when coupled with a second, unrelated antimalarial.
Owing to the use of artemisinin as a monotherapy, strains of Plasmodium falciparum have emerged that have a decreased sensitivity to the drug.
Several strategies to prevent the spread of the less resistant parasites have been put in place, such as a multifaceted approach that includes early diagnosis and appropriate treatment, decreasing drug pressure, optimising vector control, targeting the mobile population, strengthening of management and surveillance systems, and operations research.
Other, broader strategies can target the emergence and spread of drug resistance. These include mass drug administration, using multiple first-line therapies simultaneously, surveillance, active case investigation and focal control
1. Anti-tumor
After being activated, artemisinin produces some free radicals, which can destroy the body structure of some malaria larvae, and have a good resistance to the treatment of some malaria diseases or some tumors. It also has a certain inhibitory effect on many cancers, such as breast cancer or colorectal cancer.
2. Improve immunity
Artemisinin has a good effect on improving the body's immunity, because artemisinin can help the body to inhibit the division of some cells, and has a good effect on the body's immunity and resistance to bacteria and viruses. If some immune diseases occur in the body, artemisinin also has a certain therapeutic effect. Therefore, it is necessary to have a comprehensive understanding so that it can play the role of medicine.
