Journal of Psychiatric Research, 1982
The catecholamine hypothesis of affective disorders postulates that depression reflects inadequate norepinephrine activity at unspecified brain centers that regulate mood. In light of experimental data showing that the oral administration of tyrosine, precursor of the catecholamine series of neurotransmitters, can increase brain norepinephrine ...

Radiation Physics and Chemistry (1977), 1982
Abstract Blue fluorescence characteristics of dityrosine appeared in y -irradiated solutions of tyrosine, glycyl- L -tyrosine or polytyrosine (MW 110,000). The intensity of fluorescence was used for the determination of the dityrosine concentration in hydrolysed samples.

Effect of the phosphonic analogue of tyrosine on tyrosine iodination
Amino Acids, 1994Depositing ofDL-1-amino-2-(p-hydroxyphenyl)-ethylphosphonic acid (Tyr-P) on the chicken embryo induced a dose dependent decrease of the iodine uptake by the embryonic thyroid. Tyr-P interfered on iodination of tyrosine when tested with hog thyroid peroxidase (TPO) and with bovine lactoperoxidase (LPO); the analogue was recognized by the two enzymes but

Inhibition of tyrosine phenol-lyase by tyrosine homologues
Amino Acids, 2016We have designed, synthesized, and evaluated tyrosine homologues and their O-methyl derivatives as potential inhibitors for tyrosine phenol lyase (TPL, E.C. 4.1.99.2). Recently, we reported that homologues of tryptophan are potent inhibitors of tryptophan indole-lyase (tryptophanase, TIL, E.C.
