Hair analysis for drugs of abuse. XI. Disposition of benzphetamine and its metabolites into hair and comparison of benzphetamine use and methamphetamine use by hair analysis

In order to study the disposition of benzphetamine (BZP) and its metabolites, desmethyl benzphetamine (norBZP), p-hydroxy desmethyl benzphetamine (OHnorBZP), methamphetamine (MA) and amphetamine (AP), from plasma to hair in rats, an analytical method for identifying these drugs in plasma, urine and hair was developed with selected ion monitoring of gas chromatograph/mass spectrometry (GC/MS-SIM) results. After the intraperitoneal administration of BZP to rats (10 mg/kg/d, 10 d, n=3), concentrations of BZP and its metabolites in rat hair newly grown for 4 weeks were compared to the areas under the concentration versus time curve (AUCs) of these drugs in the rat plasma. The concentrations of BZP, norBZP, OHnorBZP, MA and AP in the rat hair were 14.8±1.4, 6.1±0.3, 2.6±0.5, 2.3±0.1 and 9.2±0.3 ng/mg, and the ratio of the concentrations in the hair to AUCs in the rat plasma was 3.0:0.1:0.1:0.6:0.2, respectively. This fact suggested that BZP tends to be readily incorporated into hair from blood. The method was applied to the determination of the metabolites in scalp hair and pubic hair of humans who orally ingested BZP (30 mg/d, 5 d, n=2). BZP, norBZP, MA and AP were detected at 0.14-0.56, 0.29-0.63, 0.10 and 1.06-1.66 ng/mg in the scalp hair and at 0.10-0.20, 0.13-0.18, trace-0.15 and 0.23 ng/mg in the pubic hair, respectively. It was shown that BZP use could be retrospectively distinguished from MA use by the detection of BZP and/or norBZP in hair.

Rh-Catalyzed Asymmetric Hydrogenation of α,β- and β,β-Disubstituted Unsaturated Boronate Esters

A highly enantioselective hydrogenation of α,β-unsaturated boronate esters catalyzed by Rh-(S)-DTBM-Segphos complex has been developed. Both (Z)-α,β- and β,β-disubstituted substrates can be successfully hydrogenated to afford chiral boronates with excellent enantioselectivities, up to 98 % ee. Furthermore, the obtained chiral boronate esters, as important versatile synthetic intermediates are successfully transformed to the corresponding chiral alcohols, amines and other important derivatives with maintained enantioselectivities.

Use of fenoterol and fenoterol analogues in the treatment of glioblastomas and astrocytomas

This disclosure concerns the discovery of the use of fenoterol and (R,R)- and (R,S)-fenoterol analogs for the treatment of a tumor expressing a β2-adrenergic receptor, such as a primary brain tumor, including a glioblastoma or astrocytoma expressing a β2-adrenergic receptor. In one example, the method includes administering to a subject a therapeutically effective amount of fenoterol, a specific fenoterol analog or a combination thereof to reduce one or more symptoms associated with the tumor, thereby treating the tumor in the subject.

Kinetics of oxidation of benzphetamine by compounds I of cytochrome P4502B4 and its mutants

Cytochromes P450 are ubiquitous heme-containing enzymes that catalyze a wide range of reactions in nature including many oxidation reactions. The active oxidant species in P450 enzymes are widely thought to be iron(IV)-oxo porphyrin radical cations, terme

PREPARATION OF (R,R)-FENOTEROL AND (R,R)- OR (R,S)-FENOTEROL ANALOGUES AND THEIR USE IN TREATING CONGESTIVE HEART FAILURE

This disclosure concerns the discovery of (R,R)- and (R,S)-fenoterol analogues which are highly effective at binding β2-adrenergic receptors. Exemplary chemical structures for these analogues are provided. Also provided are pharmaceutical compositions including the disclosed (R,R)-fenoterol and fenoterol analogues, and methods of using such compounds and compositions for the treatment of cardiac disorders such as congestive heart failure and pulmonary disorders such as asthma or chronic obstructive pulmonary disease.

Comparative molecular field analysis of the binding of the stereoisomers of fenoterol and fenoterol derivatives to the β2 adrenergic receptor

Stereoisomers of fenoterol and six fenoterol derivatives have been synthesized and their binding affinities for the β2 adrenergic receptor (Kiβ2-AR), the subtype selectivity relative to the β1-AR (Kiβ1-AR/K iβ2-AR) and their functional activities were determined. Of the 26 compounds synthesized in the study, submicromolar binding affinities were observed for (R,R)-fenoterol, the (R,R)-isomer of the p-methoxy, and (R,R)- and (R,S)-isomers of 1-naphthyl derivatives and all of these compounds were active at submicromolar concentrations in cardiomyocyte contractility tests. The Kiβ1-AR/K iβ2-AR ratios were >40 for (R,R)-fenoterol and the (R,R)-p-methoxy and (R,S)-1-naphthyl derivatives and 14 for the (R,R)-1-napthyl derivative. The binding data was analyzed using comparative molecular field analysis (CoMFA), and the resulting model indicated that the fenoterol derivatives interacted with two separate binding sites and one steric restricted site on the pseudo-receptor and that the chirality of the second stereogenic center affected Kiβ2 and subtype selectivity.
