Possible Interaction: Methotrexate and Phenylalanine

Research Papers that Mention the Interaction

Molecular modeling of Leu22----Phe supports the concept of the importance of Leu22 in the active site of the enzyme and indicates that replacement with phenylalanine will decrease the binding of methotrexate.

Treatment with loading doses of phenylalanine along with methotrexate reduced the level of tetrahydrobiopterin in liver.
Molecular pharmacology  •  1983  |  View Paper
Methotrexate , which inhibits the phenylalanine hydroxylase system by preventing regeneration of the tetrahydropteridine cofactor, caused parallel inhibition of the in vivo assay as well as when the conversion of phenylalanine to tyrosine was measured in liver slices.
