As a non protein active amino acid, D-TRYPTOPHAN has special physiological properties. It can be used as non nutritive sweetener, feed additive and plant growth agent in food and feed industry and agriculture. In the pharmaceutical industry, it is mainly used to synthesize various peptides to replace L-tryptophan, prolong the half-life of peptide drugs and reduce side effects, It is an important synthetic precursor of enzyme inhibitors. It can improve the immune ability of the body and delay the occurrence of allergic reaction. Most polypeptide antibiotics can inhibit or kill Gram-positive bacteria, while others can inhibit or kill Gram-negative bacteria such as Pseudomonas aeruginosa, mycobacteria, fungi, bacteria, bacteria and tumor cells. The side chain of semi synthetic antibiotics synthesized from D-TRYPTOPHAN plays an important role in its pharmacological function, and the peptide bond is difficult to be identified β- In addition, it has a wide antibacterial spectrum, low toxicity, low anaphylaxis, fast absorption, high blood concentration, long duration of drug strength and so on.

O,O-Dimethyl phosphoramidothioate is a regulatory substance necessary for microorganisms, animals and human body to synthesize nucleic acids and proteins. Most of the biological functions of O,O-Dimethyl phosphoramidothioate are based on the electrostatic reaction with DNA, RNA, protein and charged membrane components. It is produced in vivo by putrescine (butylene diamine) and S-adenosylmethionine catalyzed by a variety of enzymes. It is mainly used to produce methamidophos, acephate and other pesticide intermediates. It and spermidine exist in bacteria and most animal cells. They are important substances to promote cell proliferation. Under acidic conditions, it shows the characteristics of polycation polyamines and can bind to DNA in viruses and bacteria. It is also one of the necessary components in cell culture medium to make DNA molecules more stable and flexible.

L-Tert-Leucine can be used as a catalyst for enantioselective oxidative coupling and cyclization of hydroquinones to oxa [9] spirene, as a nutritional enhancer, animal feed additive, and for the synthesis of drugs.

Baicalein can reduce cerebrovascular resistance, improve cerebral blood circulation, increase cerebral blood flow and anti platelet aggregation. It is clinically used for the treatment of paralysis after cerebrovascular disease.

L-glutamic acid dimethyl ester hydrochloride is a diester analogue of nonessential amino acid L-glutamic acid. Dimethyl L-glutamate hydrochloride has been shown to antagonize morphine sulfate. This product can be used for biochemical reagents and pharmaceutical intermediates.
