d-tyrosine

D-Tyrosine, the D-isomer of tyrosine, acts as a negative regulator of melanin synthesis by inhibiting tyrosinase activity. Furthermore, D-Tyrosine also inhibits biofilm formation and induces the self-dispersal of biofilms, while not affecting bacterial growth.

(S)-2-Hydroxy-3-phenylpropanoic acid (L-(−)-3-Phenyllactic acid) is a chiral aromatic compound involved in phenylalanine metabolism. It is likely produced from phenylpyruvate via lactate dehydrogenase. The D-form is derived from bacterial sources, while the L-form is endogenous. Phenyllactate levels are normally very low in blood or urine, but high levels indicate phenylketonuria (PKU) and hyperphenylalaninemia (HPA). PKU is due to a deficiency of phenylalanine hydroxylase (PAH), causing phenylalanine to convert to phenylpyruvic acid rather than tyrosine.

Licochalcone D may be a potential drug for human melanoma treatment by inhibiting proliferation, inducing apoptosis via the mitochondrial pathway and blocking cell migration and invasion. Licochalcone D has cardioprotective potential against myocardial is

Rhein-8-O-beta-D-glucopyranoside(Rhein-8-glucoside calcium (Rhein-8-glucoside calcium salt) salt) shows moderate bioactivity against human Protein Tyrosine Phosphatase 1B (hPTP1B) in vitro.

Rubrofusarin 6-O-β-D-glucopyranoside, a glycosidic derivative of Rubrofusarin, functions as an inhibitor of protein tyrosine phosphatase 1B (PTP1B) with an IC50 value of 87.36 μM, and is utilized in research investigating comorbid diabetes and depression [1].

Aloe-emodin-8-O-β-D-glucopyranoside (Aloe-emodin-8-O-beta-D-glucopyranoside) exhibits moderate bioactivity against human Protein Tyrosine Phosphatase 1B (hPTP1B) in vitro.

L-Tyrosine ((S)-Tyrosine) is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine, considered a non-essential amino acid. L-Tyrosine(L-p-Tyrosine) is the levorotatory isomer of the aromatic amino acid tyrosine.

DL-Tyrosine is a natural product.
