D-Tryptophan CAS:153-94-6 Manufacturer Price

D-tryptophan, as a non-protein active amino acid, has special physiological properties. It can be used as a non-nutritional 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, which can replace L-tryptophan to prolong the half-life of peptide drugs and reduce side effects. It is an important synthetic precursor of enzyme inhibitors without developing drug resistance. It can improve the immune ability of the body and delay the occurrence of allergic reaction. Most Chemicalbook polypeptide antibiotics can resist gram-positive bacteria, and some have better inhibition or killing effect on gram-negative bacteria such as pseudomonas aeruginosa, mycobacterium, fungus, bacteria, bacteria and tumor cells. The side chain of semi-synthetic antibiotics synthesized with D-tryptophan plays an important role in its pharmacological function, and the peptide bond is difficult to be acted on by β-endonacylase, so it has a high stability, and has a wide antibacterial spectrum, low toxicity, low allergy, fast absorption, high blood concentration, and long duration of drug power.
