Metabolism of phencyclidine. The role of the carbinolamine intermediate in the formation of lactam and amino acid metabolites of nitrogen heterocycles
摘要:
The transformation of phencyclidine in a mouse liver microsome preparation to several oxidative metabolites was studied. With use of GLC and HPLC methods with internal standards, phencyclidine and six metabolites were quantitated and the amino acid 12, resulting from the alpha-oxidation of the piperidine ring, was produced in 10-50 times greater amounts than the other metabolites. While most piperidines and pyrrolidines produce an amino acid and a corresponding lactam, it was found that phencyclidine was not converted to the lactam 11.

A Staudinger/aza-Wittig reaction sequence is described that is catalytic in phosphorus. Towards this end, the phosphaneoxide is reduced in situ by diphenylsilane, which allows for substoichiometric amounts of the catalyst 5-phenyldibenzophosphole to be used. The substrate scope is investigated and benzoxazoles, benzodiazepine imidates and a 2-methoxypyrrole were successfully synthesized. These investigations

Amino acids present in domains of an umami taste receptor are described herein, wherein the amino acids interact with at least one nucleotide derivative and/or at least one transmembrane compound that potentiates, modulates, increases, and/or enhances the activity of the umami receptor. Such compounds can be used in flavor compositions to enhance the umami taste and/or palatability of food products.
