Opioid receptors play an important role in both behavioral and mood functions. Based on the structural modification of LY2456302, a series of aminobenzyloxyarylamide derivatives were designed and synthesized as κ opioid receptorantagonists. The κ opioid receptor binding ability of these compounds were evaluated with opioid receptors binding assays. Compounds 1a-d showed high affinity for κ opioid

A novel and efficient cobalt‐catalyzed oxidative isocyanide insertion with amines via two CN bond formation reactions under ultrasound irradiation conditions has been developed. This protocol provides a simple, clean and general way to synthesize guanidines or their corresponding hydrochlorides from simple starting materials under ultrasonic conditions. This chemistry could also be applied to an efficient

; Z; A; B; E; X; Q; J; V; G and M have the meanings indicated in the claims. The compounds of the formula I are valuable pharmacologically active compounds. They exhibit a strong anti-aggregating effect on platelets and thus an anti-thrombotic effect and are suitable e.g. for the therapy and prophylaxis of cardio-vascular disorders like thromboembolic diseases or restenoses. They are reversible antagonists of the platelet ADP receptor P2Y12, and can in general be applied in conditions in which an undesired activation of the platelet ADP receptor P2Y12 is present or for the cure or prevention of which an inhibition of the platelet ADP receptor P2Y12 is intended. The invention furthermore relates to processes for the preparation of compounds of the formula I, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.
(S)-2-(3,5-dimethylphenyl)pyrrolidine((S)-1), a key intermediate in the synthesis of aticaprant, was effectively prepared via a recycle process of resolution/racemization. The desired (S)-1 was obtained by resolution of its racemate with D-tartaric acid and some alkaline conditions were screened to racemize the undesired (R)-1 in the resolution mother liquor, and the best (in DMSO with KOH) was identified

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.
