In this letter, we reported the design and synthesis of three potent, selective, and orally bioavailable 11β-HSD1 inhibitors labeled with 14C: AMG 456 (1), AM-6949 (2), and AM-7715 (3). We evaluated the covalent protein binding of the labeled inhibitors in human liver microsomes in vitro and assessed their potential bioactivation risk in humans. We then studied the in vitro mechanism of 2 in human

develop methods of synthesis of fotrin analogs labeled in the ethylenimine groups with radioactive carbon /sup 14/C and with deuterium and also a chromato-mass spectral investigation of the obtained compounds with the purpose of a subsequent deepened study of the pharmacokinetics and metabolism of fotrin. /sup 14/C-ethylenimine was obtained starting from 1,2-/sup 14/C-dibromoethane. The mass spectra

The biosynthesis of the retronecine (3) portion of the pyrrolizidinealkaloidretrorsine (1) present in Senecio isatideus plants has been studied with the aid of 14C-labelled precursors. Putrescine (5), spermidine (6), and spermine (7), are the most efficient precursors of the pyrrolizidine ring. Degradations of labelled retronecine samples indicated that two molecules of each precursor are utilised
