3-(4-Idrossifenil)-D-alanina

Descrizione:

3-(4-Idrossifenil)-D-alanina, noto anche come D-Tirosina, è un derivato aminoacidico caratterizzato dalla presenza di un gruppo idrossile anello fenilico, che ne migliora la solubilità e reattività. Questo composto presenta un centro chirale, rendendolo esistente in due forme enantiomeriche, con la forma D che è biologicamente rilevante. È un aminoacido non essenziale che svolge un ruolo cruciale nella biosintesi dei neurotrasmettitori, in particolare della dopamina, ed è coinvolto in vari percorsi metabolici. Il gruppo idrossile contribuisce alla sua natura polare, permettendogli di partecipare a legami idrogeno e interagire con altre biomolecole. La D-Tirosina è spesso utilizzata nella ricerca biochimica e ha potenziali applicazioni in farmaci e integratori alimentari, in particolare per il suo ruolo nel migliorare la funzione cognitiva e l'umore. Inoltre, può essere sintetizzata attraverso vari metodi chimici o derivata da fonti alimentari, come prodotti lattiero-caseari, carne e alcune noci. La sua stabilità e reattività in condizioni fisiologiche la rendono un composto importante sia in contesti biologici che in chimica sintetica.

Applications D-Tyrosine, the stereoisomer to L-Tyrosine (T899975), is an amino acid used in various organic syntheses for antibiotics. It is used in the synthesis of (-)-anisomycin, as well as BATSI (boronic acid transition state inhibitors) which act on β-lactamases. It has also been studied as an inhibitor of microbial growth on surfaces, reducing microbial attachment to hydrophillic glass and hydrophobic polypropylene surfaces.

D-Tyrosine

CAS: 556-02-5

D-Tyrosine is an amino acid that is synthesized from the essential amino acid phenylalanine. It has been shown to have antimicrobial properties in vitro, where it inhibits the growth of bacteria by causing the disruption of the bacterial cell membrane. D-Tyrosine has also been shown to be active against gram-positive and gram-negative bacteria, as well as fungi and yeast. The antimicrobial activity may be due to its ability to form hydrogen bonds with nitrogen atoms on the surface of these microorganisms. D-Tyrosine has also been shown to have antiinflammatory properties in vitro by inhibiting prostaglandin synthesis through inhibition of enzymes such as diphenolase activity or synthetase.
D-Tyrosine is classified as a nonessential amino acid because it can be synthesized from other amino acids such as phenylalanine or leucine. It has been shown to have inhibitory effects on skin cells when applied topically, which could
