Synthesis and 5HT Modulating Activity of Stereoisomers of 3-Phenoxymethyl-4-phenylpiperidines.
摘要:
A series of pairs of enantiomers of substituted 3-phenoxymethyl-4-phenylpiperidines has been prepared from arecoline or alpha-methylstyrene by a combination of stereospecific reactions and optical resolutions. The ability of the compounds to modulate serotonin (5HT) neurotransmission in vitro was determined. Several derivatives, among which is the antidepressant paroxetine, are very potent inhibitors of 5HT reuptake. These compounds exhibit a pronounced steric requirement for inhibition of 5HT reuptake and binding to 5HT(2A) and 5HT(2C) receptors.
The present invention provides compounds of Formula I:
and pharmaceutically acceptable salts thereof, wherein R
6
and R
10
have any of the values defined therefor in the specification; pharmaceutical compositions; methods of treating conditions, diseases, and disorders; and therapeutic combinations.

Derisking the Cu-Mediated <sup>18</sup>F-Fluorination of Heterocyclic Positron Emission Tomography Radioligands
Molecules labeled with fluorine-18 (18F) are used in positron emission tomography to visualize, characterize and measure biological processes in the body. Despite recent advances in the incorporation of 18F onto arenes, the development of general and efficient approaches to label radioligands necessary for drug discovery programs remains a significant task.
