Syntheses and structure–activity relationship studies of piperidine-substituted quinolones as nonpeptide gonadotropin releasing hormone antagonists
摘要:
Syntheses and structure-activity relationships of piperidine-substituted quinolones as nonpeptide gonadotropin releasing hormone antagonists are described. Some of substituents on the piperidine ring that were investigated included a fused phenyl group, a (6R)-trifluoromethyl group, (6S) and (6R)-methyl group. This study showed that GnRH binding potency was tolerated by a small group at the 6-position of the piperidine, and blocking the 6-position by a trifluoromethyl group reduced clearance rate and increased oral bioavailability.

The configurations and preferred conformations of some substituted octahydropyrido[1,2-c]1,3-oxazines have been deduced on the basis of NMR spectra and the 2700–2850 cm−1 region of the IR spectra. The configurations of (±) sedridin and (±) sedamin have been confirmed. The importance of dipole interactions in determining the preferred conformations of this system have been illustrated.
