Previous work has shown that incorporation of either 1-aminocyclohexanecarboxylic acid (Ac6c) or alpha-methyl-p-phosphonophenylalanine ((alpha-Me)Ppp) in the phosphotyrosyl (pTyr) C-proximal position (pY + 1 residue) of Grb2 SH2 domain binding peptides confers high affinity. The tetralin-based (S)-2-amino-6-phosphonotetralin-2-carboxylic acid (Atc(6-PO3H2)) simultaneously presents

Hyperphenylalaninaemia induced by daily injections of alpha-methylphenylalanine plus phenylalanine caused 20-40% decreases in cerebral dopamine (3,4-dihydroxyphenethylamine) and noradrenaline in 7- and 11-day-old rats. alpha-Methylphenylalanine alone as well as phenylalanine alone caused cerebral dopamine depletion. However, the effects were not additive

Supplementation of 5% phenylalanine plus 0.4% alpha-methylphenylalanine to the standard diet or 1% phenylalanine plus 0.08% alpha-methylphenylalanine to the drinking water produced phenylketonuria-like conditions in 5-day-old chicks. An increase of 10 to 15-fold in the phenylalanine content was observed in

Brain phenylalanine concentrations at plasma levels raised to that in phenylketonuric subjects were studied in rats from fetal through postnatal life. Suppression of the hepatic phenylalanine hydroxylase with alpha methylphenylalanine, and injections of age-adjusted doses of phenylalanine on the next
