¹⁸F-Labelled vorozole analogues as PET tracer for aromatase

10.1002/jlcr.1502

The research aims to develop 18F-labeled vorozole analogues as PET tracers for detecting the enzyme aromatase, which converts androgens to estrogens and may influence mood and mental status. The study involves one- and two-step syntheses of two 18F-labeled vorozole analogues, [18F]FVOZ and [18F]FVOO, using key chemicals such as ethane-1,2-diyl bis(4-methylbenzenesulfonate), oxydiethane-2,1-diyl bis(4-methylbenzenesulfonate), and 1-bromo-2-fluoroethane. The one-step synthesis achieved higher radiochemical yields (36–99%) and specific radioactivities (100 GBq/mmol for [18F]FVOZ and 80 GBq/mmol for [18F]FVOO) compared to the two-step synthesis. In vitro autoradiography using frozen rat brains showed specific binding in regions corresponding to previous [11C]VOZ studies. Metabolite studies revealed that [18F]FVOZ was more stable in plasma than [18F]FVOO. The one-step synthesis method is highlighted as a more reproducible and potentially automatable approach for future tracer development.

New Symmetrical Chiral Dibenzyl- and Diphenyl-Substituted Diamido-, Dithionoamido-, Diaza-, and Azapyridino-18-crown-6 Ligands

10.1021/jo00046a020

The study focuses on the synthesis and characterization of eleven new chiral macrocycles (1-11) of the pyridino-18-crown-6 type. These compounds were prepared using various starting materials such as (S)-(+)-2-phenylglycine, formic acid, acetic anhydride, and diethylene glycol ditosylate, among others. The roles of these chemicals are crucial in the formation of the chiral diamines and glycols, which are then used to create the macrocyclic structures through cyclization reactions with compounds like dimethyl 2,6-pyridinedicarboxylate and O,O'-dimethyl 2,6-pyridinedicarbothioate. The study also investigates the enantiomeric recognition properties of these new chiral ligands with (R)- and (S)-[α-(1-naphthyl)ethyl]ammonium perchlorate using 'H NMR spectral techniques. The interactions and the degree of enantiomeric recognition are analyzed based on the differences in free energy of activation values (ΔG*) and log K values. Additionally, the X-ray analyses of the dithionoamido ligands (2, 6, and 8) reveal significant deviations of the S and N atoms from the plane of the pyridine ring, indicating structural distortions. The study provides insights into the factors influencing enantiomeric recognition and the potential applications of these chiral macrocycles in enantiomeric separations.
