Journal of analytical toxicology, 19(2), 84-86 (1995-03-01)
A metabolite of labetalol that is responsible for previous reports of false-positive assays for amphetamines by thin-layer chromatography and immunoassay has been identified. The compound, 3-amino-1-phenylbutane (APB), an oxidative metabolite of labetalol, was initially identified in a patient's urine by
Drug metabolism and disposition: the biological fate of chemicals, 21(2), 284-292 (1993-03-01)
Labetalol causes significant maternal and fetal metabolic effects in pregnant sheep (Yeleswaram et al., J. Pharmacol. Exp. Ther. 262, 683-691 (1992)). This study was undertaken to investigate the contribution of skeletal muscles in the development of metabolic acidosis induced by
Journal of the American Chemical Society, 141(12), 4963-4971 (2019-03-06)
Enantiomerically pure chiral amines are of increasing value in the preparation of bioactive compounds, pharmaceuticals, and agrochemicals. ω-Transaminase (ω-TA) is an ideal catalyst for asymmetric amination because of its excellent enantioselectivity and wide substrate scope. To shift the equilibrium of
Therapeutic drug monitoring, 38(1), 98-107 (2015-09-09)
For psychostimulants, a marked individual variability in the dose-response relationship and large differences in plasma concentrations after similar doses are known. Therefore, optimizing the efficacy of these drugs is at present the most promising way to exploit their full pharmacological
Biological mass spectrometry, 21(11), 534-540 (1992-11-01)
A sensitive and selective assay has been developed for the identification and quantitation of 3-amino-1-phenyl butane (3-APB), a metabolite of labetalol, in biological fluids using electron impact gas chromatography/mass-selective detection. Samples were extracted with n-hexane, derivatized with heptafluorobutyric anhydride and
