Application:

D-Tyrosine (H-D-Tyr-OH) (CAS: 556-02-5), amino acids and derivatives, used in peptide synthesis, used as an organic synthesis intermediate, pharmaceutical intermediate, food / feed additives, nutritional supplement, biochemical reagent or chemical reagent.   
D-Tyrosine is the D-form amino acid of Tyrosine. It is a non-essential amino acid. In animals, it can be de novo synthesized from phenylalanine. It is also the precursor of epinephrine, thyroid, hormones and melanin. Specially, study has shown that it can be taken s a chiral precusor to potent inhibitors of human Nonpancreatic secretory phospholipase A 2(IIa) with strong anti-inflammatory activity. It can also be used as a starting material for the preparation of anisomycin.
D-Tyrosine is a non-protein source of chiral amino acids, which is widely used in the synthesis of chiral drugs. For example, the peptide drug atosiban synthesized with D-Tyrosine as a chiral intermediate is a tocolytic drug, and the synthesized deacetylated anisomycin has antigenic, anti-Amoeba, anti-fungal, anti-swelling, to prevent the role of plant fungal disease, synthetic peptide drugs for the treatment of malignant tumors with special efficacy, can also be used for the lungs, central nervous system, joints, endocardium, eyes, ears, skin, gastrointestinal, urinary system inflammation with excellent efficacy of anti-inflammatory drugs.
Production method with DL-Tyrosine as raw material, acylation reaction with Chloroacetyl Chloride was carried out, filtered and concentrated, the product was extracted with boiling acetone, recrystallized from petroleum ether, and recrystallized again after acidification with hydrochloric acid.
