Basic introduction

 

Methylselenocysteine, also known as Se-methylselenocysteine, is an analog of S-methylcysteine in which the sulfur atom is replaced with a selenium atom. It is an inhibitor of DMBA-induced mammary tumors and a "chemopreventive agent that blocks cell cycle progression and proliferation of premalignant mammary lesions and induces apoptosis of cancer cell lines in culture."

Apoptosis has been proposed as the most plausible mechanism for the chemopreventive activities of selenocompounds. Se-Methylselenocysteine was more efficient at inducing apoptosis than selenite, but was less toxic. The "selenite-induced cell death could be derived from necrosis rather than apoptosis, since selenite did not significantly induce several apoptotic phenomena, including the activation of caspase-3."

In the Nutritional Prevention of Cancer Trial, selenized yeast resulted in "a reduction in the incidence of prostate cancer and in total cancer incidence"; subsequent anticancer studies using selenomethionine did not show any benefit against cancer; but, selenized yeast contains both selenomethionine and methylselenocysteine.

Biological Activity

Se-Methylselenocysteine, a precursor of methyl selenium, has powerful cancer chemopreventive activity and antioxidant activity. Se-Methylselenocysteine has oral bioactivity and can induce apoptosis.

Advantages

L-selenium-methyl-selenocysteine is a selenomethylated derivative of L-selenocysteine, the 21st essential amino acid. It is widely found in Astragalus, garlic, onion, cabbage and other plants as well as selenium-rich yeast. It has the advantages of clear chemical structure, low toxicity, high bioavailability and good selenium supplementation effect.

Efficacy

1. Tumor inhibition: L-selenomethylselenocysteine can be directly decomposed into methylselenol under the action of β-lyase, which can quickly deliver anticancer active substances to the human body.

2. Antioxidant: Selenomethyl selenocysteine can remove free radicals, improve and enhance the ability of the body's immune system to recognize viruses and foreign bodies entering the body, which can reduce the occurrence of diseases, but also activate the antioxidant system in the body, to achieve anti-aging effects.

3. Improve immunity: Selenomethyl selenocysteine can improve the proliferation of immune cells.

4. Strong bones: Selenomethyl selenocysteine can promote protein absorption, strong bones.

5. Prevention of cardiovascular diseases: Selenomethylselenocysteine can prevent cardiovascular and cerebrovascular diseases.

6. Protect the liver: selenomethyl selenocysteine can prevent hepatitis and protect the liver.

7. Alleviate the pain of chemoradiation: selenomethyl selenocysteine can alleviate the pain of chemoradiation and reduce the side effects of chemoradiation drugs.

8. Protect nerves: selenomethyl selenocysteine can protect neurotransmitter changes, prevent epilepsy, anxiety, depression.

Applying

1. Food nutrition enhancement: L-selenomethyl selenocysteine can be added to dairy products, cereals and their products, liquid and milk drinks, salt, biscuits, flower tea, infant formula powder and other foods to make nutrient-fortified foods.

2. Dietary supplement: L-selenomethyl selenocysteine can be used as a dietary supplement of selenium, which helps to improve the level of selenium in the human body, and plays various roles such as antioxidant, auxiliary treatment of cardiovascular diseases, detoxification and detoxification.

3. Medicine:Anti-inflammatory, anti-cancer and anti-cancer,L-selenomethyl selenocysteine has anti-inflammatory, anti-cancer and anti-cancer effects, not only on a variety of tumors (such as lung cancer, prostate cancer, liver cancer, etc.) has a preventive effect, but also has an auxiliary effect on cancer treatment.

In summary, L-selenomethyl selenocysteine plays an important role in food nutrition and dietary supplementation, and has shown potential in anti-inflammatory, anti-cancer and anti-cancer fields.
