Abstract
The electron-ionization mass spectra (EI-MS) of oxo- and thio-derivatives of minor tobacco alkaloids and structurally similar piperidine alkaloids, i.e. thiocotinine (1), 2'-oxo-N-methylanabasine (2), 2'-thio-N- methylanabasine (3), 2'-oxoanabasamine (4) and 2'-thioanabasamine (5) are discussed and general fragmentation routes of their molecular cations are proposed. Comparison of the data obtained for 1 with the EI-MS data of metameric metabolites of nicotine: 3'-hydroxycotinine, (A) and 5'-hydroxycotinine, (B) allows a differentiation between these metamers. The data will be useful for the identification of metabolites of alkaloids of these types in biological matrices.

Abstract
A library of compounds biased toward opioid receptor antagonist activity was prepared by incorporating N-phenylpropyl-4beta-methyl-5-(3-hydroxyphenyl)morphans as the core scaffold using simultaneous solution phase synthetic methodology. From this library, N-phenylpropyl-4beta-methyl-5-(3-hydroxyphenyl)-7alpha-[3-(1-piperidinyl)propanamido]morphan [(-)-3b] was identified as the first potent and selective kappa opioid receptor antagonist from the 5-phenylmorphan class of opioids.

Abstract
This paper reports the results of studies on the in vivo metabolic fate of the tobacco alkaloid 1-methyl-2-(3-pyridinyl)pyrrole (beta-nicotyrine) in New Zealand white rabbits. Two previously characterized metabolites, 5-hydroxy-1-methyl-5-(3-pyridinyl)-2-pyrrolidinone (5-hydroxycotinine) and 2-hydroxy-1-methyl-5-(3-pyridinyl)-3-pyrrolin-2-one, were present in low concentrations in the urine of the treated animals. The major urinary metabolite of beta-nicotyrine was identified as cis-3'-hydroxy-1-methyl-5-(3-pyridinyl)-2-pyrrolidinone (cis-3'-hydroxycotinine), the diastereoisomer of the major urinary metabolite of (S)-nicotine. The pathway leading to cis-3'-hydroxycotinine is proposed to proceed via autoxidation of 2-hydroxy-1-methyl-5-(3-pyridinyl)pyrrole, a postulated cytochrome P450-generated metabolite of beta-nicotyrine, followed by reduction of the carbon-carbon double bond present in the resulting 3-hydroxy-3-pyrrolin-2-one species. This proposal is supported by the in vivo biotransformation of 2-acetoxy-1-methyl-5-(3-pyridinyl)pyrrole, a latent form of the putative hydroxypyrrole intermediate, to cis-3'-hydroxycotinine. The in vivo conversion of 5-hydroxy-1-methyl-5-(3-pyridinyl)-3-pyrrolin-2-one to 5-hydroxycotinine is offered as evidence that supports the proposed reduction step.

Abstract
The primary metabolite of nicotine in smokers is cotinine. Cotinine is further metabolized to trans-3'-hydroxycotinine, the major urinary metabolite of nicotine in tobacco users. It was recently reported that cytochrome P450 2A6 catalyzes the conversion of cotinine to trans-3'-hydroxycotinine. In this work, we report that P450 2A6 metabolizes cotinine not only to trans-3'-hydroxycotinine but also to 5'-hydroxycotinine, norcotinine, and a fourth as yet unidentified metabolite. The products of baculovirus-expressed P450 2A6 [methyl-(3)H]cotinine metabolism were analyzed by radioflow HPLC. Three (3)H-labeled metabolites were detected and were present in approximately equal amounts. The identities of two of the metabolites were confirmed to be 5'-hydroxycotinine and trans-3'-hydroxycotinine by LC/MS/MS and LC/MS analysis and comparison to standards. The third product was not identified. A fourth product of P450 2A6-catalyzed cotinine metabolism was detected by LC/MS. It was identified by cochromatography with a standard and MS and MS/MS data to be norcotinine. An attempt was made to further characterize the unidentified (3)H-labeled metabolite by comparison to the cotinine metabolites generated by hamster liver microsomes. Hamster liver microsomes contain a P450, 2A8, which is closely related to P450 2A6, and have previously been shown to metabolize cotinine to three hydroxylated products, trans-3'-hydroxycotinine, 5'-hydroxycotinine, and N-(hydroxymethyl)norcotinine. We were unable to confirm that N-(hydroxymethyl)norcotinine was the unidentified cotinine metabolite generated by P450 2A6.

Abstract
1. N-Hydroxymethylnorcotinine; 5-(3'-pyridyl)-1-hydroxymethyl-pyrrolidone-2, was found as a new primary metabolite of cotinine in vitro. 2. N-Hydroxymethylnorcotinine was synthesized and characterized by gas chromatography-mass spectrometry, mass spectra, nuclear magnetic resonance and ultraviolet spectroscopy. 3. This new metabolite is formed by incubation of cotinine with hamster hepatic microsomes in the presence of NADPH and oxygen.

Abstract
Nicotine metabolism is exceedingly sensitive to perturbation by numerous host factors. To reduce the large variations and discrepancies in the literature pertaining to nicotine metabolism, investigators in future studies need to recognize and better control these host factors. Recent advances in the understanding of nicotine metabolism have suggested new approaches to elucidating underlying mechanisms of certain toxic effects associated with cigarette smoking.

Abstract
1. The metabolism of [3H]-S-(-)-cotinine in vivo has been investigated in the guinea pig. The quantitive determination of urinary metabolites has been carried out using a high-performance liquid radiochromagraphic procedure. Metabolite analysis of C- and N-oxidation products, and N-methylcotininium ion, were carried out on two chromatographic systems: (a) Partisil-10 SCX cation-exchange chromatography, and (b) Partisil-10 ODS reverse-phase chromatography. 2. 3-Hydroxycotinine was the major urinary metabolite of cotinine in the guinea pig, accounting for 57% of the total radioactivity in the urine. Cotinine-N-oxide constituted 18% of total metabolites in the urine, whereas neither nicotine nor the N-methylcotininium ion were detected as urinary metabolites of [3H]-S-(-)cotinine. S-(-)-Cotinine was extensively metabolized in the guinea pig; total recovery of radioactivity in 24 h urine was very high (greater than 95%) and very little cotinine was detected (less than 1%) in the urine. 3. Two unidentified metabolites of [3H]-S-(-)-cotinine were detected which collectively constituted approximately 20% of total urinary tritium.
