  Discovery of Aminobenzyloxyarylamides as κ Opioid Receptor Selective Antagonists: Application to Preclinical Development of a κ Opioid Receptor Antagonist Receptor Occupancy Tracer

  摘要：

  Arylphenylpyrrolidinylmethylphenoxybenzamides were found to have high affinity and selectivity for K 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-fluorophenyppyrrolidin-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 K opioid receptors when tested in vitro using a [S-35]-guanosine 5'O-[3-thiotriphosphate] ([S-35]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.

  通过分子内还原胺化对映选择性直接合成游离环胺

  摘要：

  可以通过一锅法通过N -Boc保护的氨基酮的分子内还原胺化来制备手性环胺。用铱和f-spiroPhos的配合物作为催化剂，可将一系列N -Boc保护的氨基酮顺利地转化为手性环状游离胺，产率高，对映选择性高（ee高达97％）。而且，该方法也可以成功地应用于κ-阿片受体选择性拮抗剂（S）-1的合成。

With the complex of iridium and f-spiroPhos as the catalyst, a range of N-Boc-protected amino ketones are smoothly transformed into chiral cyclic free amines in high yields and excellent enantioselectivities (up to 97% ee). Moreover, this method can also be successfully applied to the synthesis of a κ-opioid receptor
