Species differences in the metabolism of norephedrine in man, rabbit and rat [PDF]

open access: yesBiochemical Journal, 1973
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.

Effects of oral β‐cryptoxanthin administration on the transcriptomes of peripheral neutrophil and liver tissue using microarray analysis in post‐weaned Holstein calves

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 107, Issue 5, Page 1167-1175, September 2023., 2023
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

open access: yesActa Crystallographica Section E, 2009
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]

open access: yesBiochemical Journal, 1972
(±)-[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 ...

(5S,6R)-5-Methyl-6-phenyl-4-propyl-1,3,4-oxadiazinane-2-thione

open access: yesActa Crystallographica Section E, 2009
The title molecule, C13H18N2OS, is an oxadiazinanthione derived from (1R,2S)-norephedrine. There are two molecules in the asymmetric. Both adopt roughly half-chair conformations; however, the 5-position carbon orients out of opposite faces of the ...
