l 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.

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.

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

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.

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

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

(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.

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

Evofolin B is a natural compound isolated from the stem bark of Zanthoxylum ailanthoides. Evofolin B has an inhibitory effect on the superoxide anion produced by human neutrophils in response to formyl-L-methionine-L-leucine-L-phenylalanine cytochalasin B (fMLP CB).

3'-O-Methylmurraol may have potential anti-inflammatory activity, it exhibits inhibition (IC50 ≤ 7.31 ug mL) of superoxide anion generation by human neutrophils in response to formyl-l-methionyl-l-leucyl-l-phenylalanine cytochalasin B (fMLP CB).

AC-PHE-OME (Methyl N-acetyl-L-phenylalaninate) is a marine derived natural products found in Family Jaspidae.
