Research Papers that Mention the Interaction

Subcutaneous injection of adrenaline into normal male volunteer subjects caused large increases of plasma non-esterified fatty acids and free tryptophan , but plasma total tryptophan fell considerably.

Tryptophan infusion resulted in a marked increase in epinephrine (Premean = 23.92 (12.23) versus Postmean = 81.57 (62.36)) and decrease in norepinephrine (Premean = 257.2 (106.11) versus Postmean = 177.04 (87.15)), whereas levels of both catecholamines were stable on the "sham day.

Various protease inhibitors (e.g. phenylmethanesulfonyl fluoride (PMSF), tosyl-phenylalanine chloromethyl ketone (TosPheCH2Cl)) and substrates (e.g., tosyl-arginine methyl ester (TosArgOMe), tryptophan methyl ester (TrpOMe)) inhibit the binding of adrenal and sex steroids to their cognate receptors (Hubbard and Kalimi (1985) Mol.

SH rats, treated with the higher dose of tryptophan , also significantly reduced their urinary outputs of epinephrine and norepinephrine compared with SH controls, while both doses of tryptophan increased urinary outputs of dopamine significantly above that of SH controls.

Abstract We have previously reported that the binding of adrenal and sex steroid hormones to specific receptors is inhibited by a variety of protease inhibitors and substrates, including tryptophan methyl ester ( TME).
