BioAssay: AID 631407

Drug uptake in rat cerebellum at 3 ug/kg, iv pretreated 1 hr with 3-Fluoro-4-[4-[[ (2S)-2-(3-fluorophenyl)pyrrolidin-1-yl]methyl]- phenoxy]benzamide measured after 40 mins by LC/MS-MS analysis

Arylphenylpyrrolidinylmethylphenoxybenzamides were found to have high affinity and selectivity for kappa opioid receptors. On the basis of receptor binding assays in Chinese hamster ovary (CHO) cells expressing cloned human opioid receptors, (S)-3-fluoro-4-(4-((2-(3-fluorophenyl)pyrrolidin-1-yl)methyl)phenoxy)benzamide (25) had a K(i) = 0.565 nM for kappa opioid receptor binding while having a more ..

Description:
Title: Discovery of aminobenzyloxyarylamides as kappa opioid receptor selective antagonists: application to preclinical development of a kappa opioid receptor antagonist receptor occupancy tracer.

Abstract: Arylphenylpyrrolidinylmethylphenoxybenzamides were found to have high affinity and selectivity for kappa opioid receptors. On the basis of receptor binding assays in Chinese hamster ovary (CHO) cells expressing cloned human opioid receptors, (S)-3-fluoro-4-(4-((2-(3-fluorophenyl)pyrrolidin-1-yl)methyl)phenoxy)benzamide (25) had a K(i) = 0.565 nM for kappa opioid receptor binding while having a K(i) = 35.8 nM for mu opioid receptors and a K(i) = 211 nM for delta opioid receptor binding. Compound 25 was also a potent antagonist of kappa opioid receptors when tested in vitro using a [(35)S]-guanosine 5'O-[3-thiotriphosphate] ([(35)S]GTP-gamma-S) functional assay in CHO cells expressing cloned human opioid receptors. Compounds were also evaluated for potential use as receptor occupancy tracers. Tracer evaluation was done in vivo, using liquid chromatography-tandem mass spectrometry (LC/MS/MS) methods, precluding the need for radiolabeling. (S)-3-Chloro-4-(4-((2-(pyridine-3-yl)pyrrolidin-1-yl)methyl)phenoxy)benzamide (18) was found to have favorable properties for a tracer for receptor occupancy, including good specific versus nonspecific binding and good brain uptake.
