Species differences in the metabolism of norephedrine in man, rabbit and rat [PDF]
1. (±)-2-Amino-1-phenyl[1-14C]propan-1-ol ([14C]norephedrine) was administered orally to man, rat and rabbit and the metabolites excreted in the urine were identified and measured. Pronounced species differences in the metabolism of the drug were found. 2.

Abstract We investigated the effects of oral administration of β‐cryptoxanthin (β‐CRX), a precursor of vitamin A synthesis, on the transcriptomes of peripheral neutrophils and liver tissue in post‐weaned Holstein calves with immature immunity. A single oral administration of β‐CRX (0.2 mg/kg body weight) was performed in eight Holstein calves (4.0 ± 0 ...

(5R,6S)-4-Isopropyl-5-methyl-6-phenyl-3-propanoyl-2H-1,3,4-oxadiazinan-2-one
The title compound, C16H22N2O3, was synthesized during the course of a study on (1R,2S)-norephedrine-derived 1,3,4-oxadiazinan-2-ones. The conformation adopted by the isopropyl group is pseudo-axial relative to the oxadiazinan core.

Norephedrines as metabolites of [14C]amphetamine in urine in man [PDF]
(±)-[14C]Amphetamine sulphate (20mg) was administered orally to each of two human male subjects, and 80–85% of the14C was excreted in the urine in 2 days. The metabolites in the first day's urine were examined quantitatively. Apart from the metabolites previously described (Dring et al., 1970), norephedrine (2.2 and 2.6% of dose in the two subjects ...
