Design, synthesis and evaluation of substituted piperidine based KCNQ. openers as novel antiepileptic agents

Epilepsy is a land of disease with complicated pathogenesis. KCNQ (Kv7) is a voltage dependent potassium channel that is mostly associated with epilepsy and thus becomes an important target in the treatment of epilepsy. In this paper, a series of substituted piperidine derivatives targeting KCNQ were designed and synthesized by using scaffold hopping and active substructure hybridization. Compounds were evaluated by fluorescence-based thallium influx assay, Rb+ flow assay and electrophysiological patch-clamp assay. Results showed that some compounds possessed more potent potassium channel opening activity than Retigabine. More significantly, compound 11 was found to have good pharmacokinetic profiles in vivo.

1,2,3-Triazole based bisphosphine, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)phenyl)-4-phenyl-1H-1,2,3-triazole: an ambidentate ligand with switchable coordination modes

The reaction of 1-(2-bromophenyl)-4-phenyl-1H-1,2,3-triazole (1) with Ph2PCl yielded bisphosphine, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)phenyl)-4-phenyl-1H-1,2,3-triazole (2). Bisphosphine 2 exhibits ambidentate character in either the kappa(2)-P, N or kappa(2)-P, P coordination mode. Treatment of 2 with [M(CO)(4)(piperidine)(2)] (M = Mo and W) yielded kappa(2)-P, N and kappa(2)-P, P coordinated Mo-0 and W-0 complexes [M(CO)(4)(2)] [M = W-kappa(2)-P, N (4); Mo-kappa(2)-P, P (5); W-kappa(2)-P, P (6)] depending on the reaction conditions. Formation and stability of kappa(2)-P, P coordinated Mo-0 and W-0 complexes were assessed by time dependent P-31{H-1} NMR experiments and DFT studies. The complex 4 on treatment with [AuCl(SMe2)] afforded the hetero-bimetallic complex [m-PN, P-{o-Ph2P(C6H4){1,2,3-N3C(Ph) C(PPh2AuCl)}-kappa(2)-P, N}W(CO) 4] (7). The 1 : 1 reaction between 2 and [CpRu(PPh3) 2Cl] yielded [(h 5-C5H5) RuCl{o-Ph2P(C6H4){1,2,3-N3C(Ph) C(PPh2)}}-kappa(2)-P, P] (8), whereas the similar reaction with [Ru(h 6-p-cymene) Cl-2] 2 in a 2 : 1 molar ratio produced a cationic complex [(h 6-p-cymene) RuCl{o-Ph2P(C6H4){1,2,3-N3C(Ph) C(PPh2)}}-kappa(2)-P, N] Cl (9). Similarly, treatment of 2 with [M(COD)(Cl)(2)] (M = Pd and Pt) in a 1 : 1 molar ratio yielded PdII and PtII complexes [{o-Ph2P(C6H4){1,2,3-N3C(Ph) C(PPh2)}-kappa(2)-P, P} PdCl2] (10) and [{o-Ph2P(C6H4){1,2,3-N3C(Ph) C(PPh2)}-kappa(2)-P, P} PtCl2] (11). The reaction of 2 with 2 equiv. of [AuCl(SMe2)] afforded [Au2Cl2{o-Ph2P(C6H4) {1,2,3-N3C(Ph) C(PPh2)}}-m-P, P] (12). Most of the complexes have been structurally characterized. Palladium complex 10 shows excellent catalytic activity towards Cu-free Sonogashira alkynylation/ cyclization reactions.

The True Fate of Pyridinium in the Reportedly Pyridinium-Catalyzed Carbon Dioxide Electroreduction on Platinum

Protonated pyridine (PyH+) has been reported to act as a peculiar and promising catalyst for the direct electroreduction of CO2 to methanol and/or formate. Because of recent strong incentives to turn CO2 into valuable products, this claim triggered great interest, prompting many experiments and DFT simulations. However, when performing the electrolysis in near-neutral pH electrolyte, the local pH around the platinum electrode can easily increase, leading to Py and HCO3- being the predominant species next to the Pt electrode instead of PyH+ and CO2. Using a carefully designed electrolysis setup which overcomes the local pH shift issue, we demonstrate that protonated pyridine undergoes a complete hydrogenation into piperidine upon mild reductive conditions (near 0V vs. RHE). The reduction of the PyH+ ring occurs with and without the presence of CO2 in the electrolyte, and no sign of CO2 electroreduction products was observed, strongly questioning that PyH+ acts as a catalyst for CO2 electroreduction.

Detailed In Vitro Pharmacological Characterization of the Clinically Viable Nociceptin/Orphanin FQ Peptide Receptor Antagonist BTRX-246040

The peptide nociceptin/orphanin FQ (N/OFQ) is the natural ligand of the N/OFQ receptor (NOP), which is widely expressed in the central and peripheral nervous system. Selective NOP antagonists are worthy of testing as innovative drugs to treat depression, Parkinson disease, and drug abuse. The aim of this study was to perform a detailed in vitro characterization of BTRX-246040 (also known as LY2940094, [2-[4-[(2-chloro-4,4-difluoro-spiro[5H-thieno [2,3-c]pyran-7,4′-piperidine]-1′-yl)methyl]-3-methyl-pyrazol-1-yl]-3-pyridyl]methanol), a novel NOP antagonist that has been already studied in humans. BTRX-246040 has been tested in vitro in the following assays: calcium mobilization in cells expressing NOP and classic opioid receptors and chimeric G proteins, bioluminescence resonance energy transfer assay measuring NOP interaction with G proteins and beta-arrestins, the label-free dynamic mass redistribution assay, and the electrically stimulated mouse vas deferens. BTRX-246040 was systematically compared with the standard NOP antagonist SB-612111. In all assays, BTRX246040 behaves as a pure and selective antagonist at human recombinant and murine nativeNOP receptors displaying 3-10-fold higher potency than the standard antagonist SB-612111. BTRX246040 is an essential pharmacological tool to further investigate the therapeutic potential of NOP antagonists in preclinical and clinical studies. SIGNIFICANCE STATEMENT NOP antagonists may be innovative antidepressant drugs. In this research, the novel clinically viable NOP antagonist BTRX-246040 has been deeply characterized in vitro in a panel of assays. BTRX-246040 resulted a pure, potent, and selective NOP antagonist.

Trace level determination of chloroacetyl chloride and degradation products by derivatization gas chromatography

A gas chromatographic procedure has been developed for the trace determination of chloroacetyl chloride (CAC) and two of its impurities: methyl chloroacetate (MCA) and chloroacetic acid (CAA). All three compounds are derivatized using piperidine in dichioroethane prior to their analysis via gas chromatography coupled with a flame ionization detection (GC-FID). Recoveries of each compound were assessed in two different pharmaceutical matrices (intermediate and final active pharmaceutical ingredient) and ranged from 75 to 125%. The limit of quantitation has been determined to be 0.10% wt/wt for CAA and 0.03% wt/wt for CAC and MCA. The linearity ranged from 0.03 to 5.00% wt/wt for CAC and MCA and from 0.10 to 5.00% wt/wt for CAA, with correlation coefficients from 0.9995 to 1.0000. Repeatability was evaluated at LOQ and at 5.00% wt/wt and was found to be between 1.4-3.0%. (C) 2017 Elsevier B.V. All rights reserved.

Design and Identification of a GPR40 Full Agonist (SCO-267) Possessing a 2-Carbamoylphenyl Piperidine Moiety

GPR40/FFAR1 is a G-protein-coupled receptor expressed in pancreatic beta-cells and enteroendocrine cells. GPR40 activation stimulates secretions of insulin and incretin, both of which are the pivotal regulators of glycemic control. Therefore, a GPR40 agonist is an attractive target for the treatment of type 2 diabetes mellitus. Using the reported biaryl derivative 1, we shifted the hydrophobic moiety to the terminal aryl ring and replaced the central aryl ring with piperidine, generating 2-(4,4-dimethylpentyl)phenyl piperidine 4a, which had improved potency for GPR40 and high lipophilicity. We replaced the hydrophobic moiety with N-alkyl-N-aryl benzamides to lower the lipophilicity and restrict the N-alkyl moieties to the presumed lipophilic pocket using the intramolecular pi-pi stacking of cis-preferential N-alkyl-N-aryl benzamide. Among these, orally available (3S)-3-cyclopropyl-3-(2-((1-(2-((2,2-dimethylpropyl)(6-methylpyridin-2-yl)carbamoyl)-5-methoxyphenyl)piperidin-4-yl)methoxy)pyridin-4-yl)propanoic acid (SCO-267) effectively stimulated insulin secretion and GLP-1 release and ameliorated glucose tolerance in diabetic rats via GPR40 full agonism.
