What Is an Antitoxin?

Antitoxin (antitoxin) is a specific antibody that has a neutralizing effect on toxins or an antibody that can neutralize a certain toxin or a serum containing such antibodies. Toxoids are used for immunization and vaccination, so that the body can produce corresponding antitoxins, which can prevent diseases.

Bacterial toxins (commonly referred to as

Plant antitoxin is an important part of the plant defense system. The mechanism of plant antitoxin production under the action of elicitors and its precursor as a biological pesticide is the current research focus. Biological activities, such as soybean antitoxin has antioxidant properties, estrogen-like effects and so on. In recent years, phytoalexins have attracted attention as a functional ingredient of food because of their ability to be induced and synthesized in plants.

Common phytoalexins and antibiotics include terpenes, phenols, indoles, bisbenzenes, coumarins, quinones, lactones, benzofurans, and alkaloids. ^[1]

Previous research on plant toxins mainly focused on plant disease resistance and its synthesis mechanism and pathway in plants. At present, some people have also cultivated insect resistance and weed control through biotechnology (including genetic engineering, enzyme engineering, protein engineering, etc.). Plant pesticides. Increasing research has proven that phytoalexins also have multiple biological activities on the human body, but they are absent or low in healthy plants. They can be abundant in plants through external stimulation and induction during and after birth. Generate and enrich. Using plant antitoxin as a functional ingredient, using its "inducibility", to screen suitable induction methods to increase its content in plants, to directly obtain natural foods and functional food processing raw materials with high content of functional ingredients as functions The preparation of sex food provides new research ideas and engineering methods. ^[1]

Sakuratin belongs to flavone phytoalexins. Flavone compounds have various physiological activities, and their structure and activity are closely related. The substitution of different groups on the A ring and the B ring or the same substituent at different positions will cause a large difference in the physiological activities of these compounds. The substituents in natural products are mostly hydroxymethoxy, iso Pentenyl, benzyloxy, aglycone, and Geranyl, Lavandulyl, etc. ^[2]

Antitoxin biological activity

Plant antitoxins have a variety of biological activities, but they are absent or low in healthy plants, which makes it difficult to use antitoxins as functional food additive factors. Due to the characteristics of plant antitoxins that are synthesized in plants after being induced by external or abiotic elicitors, if a suitable elicitor can be screened to induce the plant, a large amount of functional plant antitoxins are synthesized in the plant, and the plant body is functional. The natural processing factory of ingredients can obtain directly utilized natural products with high biological activity, such as grapes rich in resveratrol, soybeans rich in daidzein and soybean antitoxin, etc .; high-quality processing raw materials can also be obtained, improving Processing efficiency of functional foods, such as functional wine and soy products. ^[1]

The phytoalexin scoparone is a coumarin derivative with vasodilation and anti-allergic activities. Brassinin, which is abundant in cabbage, is an indole phytoalexin and has anticancer effect. Benzofuran phytoalexins have anti-hyperglycemic effects and are cytotoxic to liver metastatic cancer cells and fibrosarcoma cells.
