| Overview | phenylalanine scientific name α-amino-β-phenylpropionic acid, is a kind of α-amino acid, there are L-form, D-form and racemic DL-form, wherein L-form is one of the essential amino acids for human body. Phenylalanine is a new amino acid, which was first discovered by Schulze and Barbieri in the late Eighties of the ninth century, and was isolated from lupin seedlings. An empirical chemical formula for C9H11NO2 was proposed. Erlemeyer and Lipp successfully synthesized phenylalanine by chemical synthesis for the first time in 1882, but their spatial configuration was not explored. Further research on phenylalanine has been carried out since Fischer's accidental isolation of phenylalanine in the hydrolysis of casein with hydrochloric acid in 1901. D-phenylalanine is a kind of α-amino acid, the physical state is white powder or white crystalline solid at room temperature, melting point 283 ℃, isoelectric point (25 ℃) is 5.48,25 ° c in water solubility 27g/L, slightly soluble in methanol, ethanol, insoluble in ether, etc., specific rotation [α]25D = 34.5(c = 1.0,H2O). Like other D-amino acids, D-phenylalanine is a very important chiral intermediate in organic synthesis, new drug development and synthesis of polypeptide compounds, and because of the particularity of the structure and activity of D-phenylalanine amino acid, more and more people pay attention to it. |
| Use | for biochemical studies. The product is a drug intermediate, mainly used for the treatment and prevention of osteoporosis, cardiovascular, diabetes, arteriosclerosis and other diseases. D-Phenylalanine, the stereosomer of L-Phenylalanine (P319415) has been used in the synthesis of Schaeffer. They exhibit the ability to exhibit Mycobacterium tuberculosis type II dehydroquinase. used as a pharmaceutical intermediate or API for the synthesis of nateglinide and other drugs |
| production method | with DL-phenylalanine as raw material, acylation reaction with acetic anhydride, acetyl DL-phenylalanine, by acylase resolution, hydrochloric acid hydrolysis products. |
