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.

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.

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.

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.

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.

Curcumin-loaded electrospun nonwoven as a colorimetric indicator for volatile amines

Colorimetric indicators are useful in intelligent food packaging applications. As a natural food colorant, curcumin is a promising colorimetric indicator for the detection of alkaline compounds produced during food spoilage. In this study, curcumin-loaded electrospun nonwovens were developed for the detection of amines, which are principal spoilage volatiles of fish and aquatic products. The spin dope solution for electrospinning was prepared by dispersing curcumin (0.32% w/w) in 14% (w/w) polyvinylpyrrolidone (PVP) or 9% (w/w) ethylcellulose (EC)/0.2% (w/w) poly(ethylene oxide) (PEO) solution in anhydrous ethanol. Curcumin-loaded nonwovens were obtained by free surface electrospinning and subsequently characterized for amine detection. When exposed to amine volatiles, the nonwoven indicators exhibited striking yellow-to-orange/red color transition, along with a reduction in curcumin’s fluorescence intensity. Both EC/PEO- and PVP-based nonwovens were capable of discriminating six different volatile amines (trimethylamine, ammonia, dimethylamine, trie-thylamine, piperidine and hydrazine) at 0.2 mmol level. Comparing the two nonwoven carriers, EC/PEO resulted in smaller fiber diameter (1.06 mu m) and higher curcumin loading efficiency (91%) than those derived from PVP (83% loading efficiency and 1.52 mu m diameter). The limit of detection (LOD) and limit of quantitation (LOQ) of using EC/PEO-based fiber for amine detection were lower than PVP-based fiber, except for TMA.

Total Synthesis of (-)-Anaferine: A Further Ramification in a Diversity-Oriented Approach

The piperidine ring is a widespread motif in several natural bioactive alkaloids of both vegetal and marine origin. In the last years, a diversity-oriented synthetic (DOS) approach, aimed at the generation of a library of piperidine-based derivatives, was developed in our research group, employing commercially available 2-piperidine ethanol as a versatile precursor. Here, we report the exploration of another ramification of our DOS approach, that led us to the stereoselective total synthesis of (-)-anaferine, a bis-piperidine alkaloid present in Withania somnifera extract. This natural product was obtained in 9% overall yield over 13 steps, starting from a key homoallylic alcohol previously synthesised in our laboratory. Therefore, the collection of piperidine-derivatives accessible from 2-piperidine ethanol was enriched with a new, diverse scaffold.

Design, synthesis, and biological evaluation of novel oxadiazole- and thiazole-based histamine H3R ligands

Histamine H-3 receptor (H3R) is largely expressed in the CNS and modulation of the H3R function can affect histamine synthesis and liberation, and modulate the release of many other neurotransmitters. Targeting H3R with antagonists/inverse agonists may have therapeutic applications in neurodegenerative disorders, gastrointestinal and inflammatory diseases. This prompted us to design and synthesize azole-based H3R ligands, i.e. having oxadiazole- or thiazole-based core structures. While ligands of oxadiazole scaffold were almost inactive, thiazole-based ligands were very potent and several exhibited binding affinities in a nanomolar concentration range. Ligands combining 4-cyanophenyl moiety as arbitrary region, para-xylene or piperidine carbamoyl linkers, and/or pyrrolidine or piperidine basic heads were found to be the most active within this series of thiazole-based H3R ligands. The most active ligands were in silico screened for ADMET properties and drug-likeness. They fulfilled Lipinski’s and Veber’s rules and exhibited potential activities for oral administration, blood-brain barrier penetration, low hepatotoxicity, combined with an overall good toxicity profile.

Studies on Instructive Construction of exo-Olefin Terminated Five-and Six-Membered Nitrogen Heterocycles: SmI2-Mediated Intramolecular Cyclization of Haloalkynals

Stereoselective construction of exo-olefin terminated pyrrolidine and piperidine frameworks was developed by employing SmI2-mediated intramolecular radical cyclization of haloalkynaks. The radical cyclization affording 2,3-disubstituted pyrrolidines and piperidines proceeded in a highly stereoselective manner. However, decreasing stereoselectivety was observed in the preparation of 2,4-disubstituted pyrrolidine and 3,4-disubstituted piperidine derivatives in the cyclization.
