D-Tryptophan(CAS:153-94-6)

As a non protein active amino acid, D-TRYPTOPHAN has special physiological properties. It can be used as a non nutritional sweetener, feed additive and plant growth agent in food, feed industry and agriculture. In the pharmaceutical industry, D-TRYPTOPHAN is mainly used to synthesize various polypeptides to replace L-tryptophan to prolong the half-life of peptide drugs and reduce side effects. It will not produce drug resistance and become an important synthetic precursor of enzyme inhibitors. It can improve the immune ability of the body and delay the occurrence of allergic reaction. Most peptide antibiotics can resist Gram-positive bacteria, and some can inhibit or kill Gram-negative bacteria such as Pseudomonas aeruginosa, Mycobacterium, fungi, bacteria, bacteria and tumor cells. The side chain of semisynthetic antibiotics synthesized with D-TRYPTOPHAN plays an important role in its pharmacological function, and the peptide bond is difficult to be β- Endoacylase has high stability, wide antibacterial spectrum, low toxicity, low allergy, fast absorption, high blood concentration, long duration of drug power, etc.
