phenylalanine

L-Phenylalanine (3-Phenyl-L-alanine) is an essential amino acid and the precursor of the amino acid tyrosine, acts as an antagonist at α2δ calcium channels.

D-Phenylalanine, a necessary aromatic amino acid, is a precursor of thyroxine, dopamine, melanin, and noradrenaline (norepinephrine).

N-Acetyl-L-phenylalanine (N-Ac-Phenylalanine) is an essential amino acid produced for medical, feed, and nutritional applications. It appears in large amount in urine of patients with phenylketonuria which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine. Acetylphenylalanine is a product of enzyme phenylalanine N-acetyltransferase in the pathway phenylalanine metabolism.

Phenylalanine betaine is a Standard reference.

DL-Phenylalanine is a natural product

Phenylalanine N,N,N-Tri-Me betaine is a useful organic compound for research related to life sciences. The catalog number is T126137 and the CAS number is 125982-49-2.

4-Amino-L-phenylalanine (4APhe) is a TcCA activator, useful for studying protozoan pathogen infections.

Leucyl-phenylalanine (H-LEU-PHE-OH) is a dipeptide compound that can be used for protein synthesis.

N-Lactoyl-Phenylalanine (Lac-Phe) is a peptide coupling of lactic acid and phenylalanine, one of the metabolites in acute exercise, which can be used in the study of obesity and metabolism-related diseases.

Benzoylphenylalanine (LBPA) can be used as a photoaffinity peptide inactivator.

Alanylphenylalanine (Ala-phe) is a compound isolated from the brainstem of calves.

N-Benzyloxycarbonyl-N-Glycylphenylalanine is a useful organic compound for research related to life sciences and the catalog number is T131549.

N-benzyl-N-methylphenylalanine is a useful organic compound for research related to life sciences and the catalog number is T131578.

Phenylpyruvic acid (3-Phenylpyruvic acid) is a keto-acid that is an intermediate or catabolic byproduct of phenylalanine metabolism. It has a slight honey-like odor. Levels of phenylpyruvate are normally very low in blood or urine. High levels of phenylpyruvic acid can be found in the urine of individuals with phenylketonuria (PKU), an inborn error of metabolism.

Phenyl acetate (Acetic acid phenyl ester) is an aromatic fatty acid metabolite of phenylalanine with potential antineoplastic activity. Naturally occurring in mammals, phenylacetate induces differentiation, growth inhibition, and apoptosis in tumor cells.

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.

H-Phe-Phe-OH is a dipeptide composed of two phenylalanine (an essential amino acid and precursor to tyrosine) units linked together.

(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.

DL-Dopa is a phenylalanine beta-hydroxylated derivative.

Aureusimine B, also known as phevalin, is a natural pyrazinone produced by certain fungi and by Staphylococcus spp., including S. aureus. Its synthesis appears to be initiated by a conserved nonribosomal peptide synthetase that creates a dipeptide (phenylalanine-valine) aldehyde, which then undergoes cyclization and oxidation. Aureusimine B inhibits calpain in a casein hydrolysis assay (IC50 = 1.3 μM), contributes to S. aureus infection in mice, and alters human keratinocyte gene expression.

2-Propen-1-one, 1-(2,6-dimethoxyphenyl)-3-(4-hydroxyphenyl)- can be used in studies about the inhibition against L-phenylalanine ammonia-lyase.

γ-Glu-Phe TFA(7432-24-8 free base) is a dipeptide composed of gamma-glutamate and phenylalanine and is a proteolytic breakdown product of larger proteins. It is probably formed by transpeptidation between glutathione and the corresponding amino acid, catalyzed by gamma-glutamyl transpeptidase.

Phenylalanylalanine (H-Phe-Ala-OH) is a dipeptide composed of phenylalanine and alanine, produced during incomplete protein digestion or catabolism [1].

Taxacin shows strong inhibitory effects on platelet aggregation induced by arachidonic acid (IC(50):21.9 microM). Taxacin can suppress the superoxide generation induced by N-formyl-methionyl-leucyl-phenylalanine (fMLP) and arachidonic acid (AA) in a conce
