Novel agonist of alpha(4)beta(2)* neuronal nicotinic receptor with antinociceptive efficacy in rodent models of acute and chronic pain

Objective: To demonstrate the antinociceptive and antihypersensitivity mechanisms of Cris-104 (1- {2-[5-(4-fluoropheny1)-1H-pyrazol-4-yl]ethyl}piperidine), a novel selective alpha(4)beta(2)* nicotinic acetylcholine receptor (nAChR) agonist, in rodent acute/inflammatory and chronic pain models. Materials and methods: Hot-plate and formalin tests in mice were used to examine Cris-104-induced antinociceptive effects on thermal/inflammatory pain. Cris-104 effects on hypersensitivity, norepinephrine (NE) release in the spinal dorsal horn, and neuronal activity in the locus coeruleus (LC) were examined in rats with lumbar spinal nerve ligation using behavioral, microdialysis, and extracellular recording methods. Cris-104 effects on spontaneous locomotion were examined in an open-field test. Results: Cris-104 induced dose-dependent antinociception effects in hot-plate and formalin tests, and these effects were blocked by the general nAChR antagonist mecamylamine, the selective alpha(4)beta(2)* nAChR antagonist dihydro-beta-erythroidine, and the alpha(2)-adrenoceptor antagonist yohimbine, but not by the alpha(2)-adrenoceptor antagonist prazosin. Systemic and spinally perfused Cris-104 increased NE concentrations in microdialysates from the spinal cord in both normal and SNL, rats. Systemic Cris-104 increased neuronal activity in the LC of normal rats. Mecamylamine blocked the effects of Cris-104 on spinal NE release and LC neuronal activity. Systemic Cris-104 did not affect locomotor activity significantly. Conclusion: The alpha(4)beta(2) neuronal nAChR agonist, Cris-104, was effective for treatment of pain via descending noradrenergic inhibition of pain signaling.

The Abuse Potential of Novel Synthetic Phencyclidine Derivative 1-(1-(4-Fluorophenyl)Cyclohexyl)Piperidine (4 ‘-F-PCP) in Rodents

The dissociative anesthetic phencyclidine (PCP) and PCP derivatives, including 4 ‘-F-PCP, are illegally sold and abused worldwide for recreational and non-medical uses. The psychopharmacological properties and abuse potential of 4 ‘-F-PCP have not been fully characterized. In this study, we evaluated the psychomotor, rewarding, and reinforcing properties of 4 ‘-F-PCP using the open-field test, conditioned place preference (CPP), and self-administration paradigms in rodents. Using Western immunoblotting, we also investigated the expression of dopamine (DA)-related proteins and DA-receptor-mediated downstream signaling cascades in the nucleus accumbens (NAc) of 4 ‘-F-PCP-self-administering rats. Intraperitoneal administration of 10 mg/kg 4 ‘-F-PCP significantly increased locomotor and rearing activities and increased CPP in mice. Intravenous administration of 1.0 mg/kg/infusion of 4 ‘-F-PCP significantly enhanced self-administration during a 2 h session under fixed ratio schedules, showed a higher breakpoint during a 6 h session under progressive ratio schedules of reinforcement, and significantly altered the expression of DA transporter and DA D1 receptor in the NAc of rats self-administering 1.0 mg/kg 4 ‘-F-PCP. Additionally, the expression of phosphorylated (p) ERK, pCREB, c-Fos, and FosB/Delta FosB in the NAc was significantly enhanced by 1.0 mg/kg 4 ‘-F-PCP self-administration. Taken together, these findings suggest that 4 ‘-F-PCP has a high potential for abuse, given its robust psychomotor, rewarding, and reinforcing properties via activation of DAergic neurotransmission and the downstream signaling pathways in the NAc.

InBr3-Catalyzed Synthesis of Highly Functionalized Piperidines and Benzo[a]Pyrano[2,3-c] Phenazines

A versatile, operationally simple and highly efficient protocol for the synthesis of highly functionalized piperidines have been developed by the three-component reaction of aromatic aldehydes, aromatic amines and b-ketoesters catalyzed by InBr3 in ethanol. Also, InBr3 is demonstrated to be an efficient catalyst for synthesis of benzo[a]pyrano[2,3-c] phenazines. The significant advantages of this protocol are highlighted by excellent yields, short reaction times, avoidance of toxic solvent and broader substrate scope.

Crystal Structure and Catalytic Activity of A Novel Cd(II) Coordination Polymer Formed by Dicarboxylic Ligand

A new Cd(II) coordination polymer, {[Cd-3(L)(2)(DMF)(2)(H2O)(2)] H2O}n (H2L = 1,3-bisbenzyl-2imidazolidine- 4,5-dicarboxylic acid) was synthesized by one-pot synthesis method from 1,3-bisbenzyl-2imidazolidine- 4,5-dicarboxylic acid, NaOH, DMF, and Cd(NO3)(2) 4H(2)O. Its structure was determined by elemental analysis and single crystal X-ray diffraction. Structural analysis shows that three Cd(II) ions are all six-coordinated with four oxygen atoms of four 1,3-bisbenzyl-2-imidazolidine-4,5-dicarboxylate ligands and two O atoms from two DMF molecules (Cd1) or two oxygen atoms of two coordinated H2O molecules (Cd2 and Cd3) to form an octahedral coordination geometry. The Cd(II) coordination polymer displays a 1D chained structure by the bridging carboxylate groups from 1,3-bisbenzyl-2-imidazolidine4,5- dicarboxylate ligands. The conversion of benzaldehyde is 90.9%, which is 40 similar to 50% higher than those of the other three aldehydes (4-methylbenzaldehyde, p-methoxybenzaldehyde and 3chlorobenzaldehyde), so the Cd(II) coordination polymer catalyst shows better catalytic activity for the coupling reaction of benzaldehyde, phenylacetylene, and piperidine than the other three aldehydes.

Alternative Reactivity of Leucine 5-Hydroxylase Using an Olefin-Containing Substrate to Construct a Substituted Piperidine Ring

Applying enzymatic reactions to produce useful molecules is a central focus of chemical biology. Iron and 2-oxoglutarate (Fe/2OG) enzymes are found in all kingdoms of life and catalyze a broad array of oxidative transformations. Herein, we demonstrate that the activity of an Fe/2OG enzyme can be redirected when changing the targeted carbon hybridization from sp(3) to sp(2). During leucine 5-hydroxylase catalysis, installation of an olefin group onto the substrate redirects the Fe(IV)-oxo species reactivity from hydroxylation to asymmetric epoxidation. The resulting epoxide subsequently undergoes intramolecular cyclization to form the substituted piperidine, 2S,5S-hydroxypipecolic acid.

Luminescent complexes of iridium(iii) with aliphatic amines and detection of biogenic amines

The straightforward reaction of [Ir-2(ppy)(4)(mu-Cl)(2)] with an excess of aliphatic amines yields luminescent iridium complexes of general formula [IrCl(ppy)(2)(amine)] [amine = n-octylamine (1), t-butylamine (2), piperidine (3)]. The higher sterical hindrance of the amine in complex 2 was the responsible of its equilibrium with the starting materials. The luminescence of 1 and 3 has been studied showing emission at 508 and 509 nm respectively. As the aliphatic amines can be considered models of biogenic amines, this luminescence has been used to explore the viability of this reaction in the detection of biogenic amines. The exposition to vapors of biogenic amines of a solution of [Ir-2(ppy)(4)(mu-Cl)(2)] in CH2Cl2 or in different solid supports, showed that it was possible to detect the amines in a quick and easy way, with limits of detection value (in solution of methylene chloride) of 4.8 mu M for cadaverine.

N-aryl-piperidine-4-carboxamides as a novel class of potent inhibitors of MALT1 proteolytic activity

Starting from a weak screening hit, potent and selective inhibitors of the MALT1 protease function were elaborated. Advanced compounds displayed high potency in biochemical and cellular assays. Compounds showed activity in a mechanistic Jurkat T cell activation assay as well as in the B-cell lymphoma line OCI-Ly3, which suggests potential use of MALT1 inhibitors in the treatment of autoimmune diseases as well as B-cell lymphomas with a dysregulated NF-kappa B pathway. Initially, rat pharmacokinetic properties of this compound series were dominated by very high clearance which could be linked to amide cleavage. Using a rat hepatocyte assay a good in vitro-in vivo correlation could be established which led to the identification of compounds with improved PK properties. (C) 2018 Elsevier Ltd.

Immobilization of Small-Molecule Ligands Containing Secondary or Tertiary Amine Groups onto TiO2-Supported Ru Catalysts Driven by the Hydrophobic Effect

A strategy for effectively immobilizing small-molecule ligands onto TiO2-supported Ru catalysts is described. The immobilization was based on a simple two-phase centrifugation technique and driven by the hydrophobic effect, likely leading to the formation of hydrophobic clusters of small-molecule ligands. By using this strategy, a library of ligands containing secondary or tertiary amine groups and hydrophobic chains were successfully immobilized onto TiO2-supported Ru catalysts. Of these ligands, ligands containing 2,2,6,6-tetramethyl-1-piperidine-N-oxyl (TEMPO) moieties significantly improved the selectivity for aldehyde at high conversion in aerobic oxidation of alcohols, resulting from the inhibition of auto-oxidation of aldehydes. This strategy can generate diversity in preparation of organic/inorganic hybrid catalysts.

The reactions of chlorine dioxide with inorganic and organic compounds in water treatment: kinetics and mechanisms

Chlorine dioxide (ClO2), as an alternative to chlorine, has been widely applied in water treatment. In order to better understand the performance of ClO(2)in water treatment, the kinetics and mechanisms of ClO(2)reactions with inorganic and organic compounds found in waters are critically reviewed. In the case of inorganic compounds, ClO(2)reacts with I-, CN-, NO2-, SO32-, Fe(ii) and Mn(ii) rapidly at apparent second-order reaction rate constants (k(app)) of 10(2)-10(6)M(-1)s(-1)at pH 7.0 and barely reacts with NH(4)(+)and Br-. In the case of organic compounds, ClO(2)selectively reacts with compounds with electron-rich moieties, such as phenols (k(app)= 10(3)-10(9)M(-1)s(-1)), anilines (k(app)= 10(5)-10(8)M(-1)s(-1)), and thiols (k(app)> 10(8)M(-1)s(-1)). ClO(2)also shows high reactivity towards aliphatic tertiary amines and heterocyclic nitrogenous compounds (i.e., indoles and piperidines) withk(app)of 10(1)-10(6)M(-1)s(-1)at pH 7.0, but low reactivity with unsaturated structures (i.e., olefins and aldehydes). Thek(app)values at pH 7.0 in ClO(2)oxidation vary over 14 orders of magnitude. Electron transfer is the dominant pathway for ClO(2)reactions. Quantitative structure-activity relationships (QSARs) can be used to predict the species-specific secondary reaction rate constants for ClO(2)oxidation of compounds containing phenolic and amine structures. Little modifications are expected on the structure of the parent compounds upon the primary attack of ClO2, but further oxidation generally leads to the formation of quinones, aldehydes and carboxylic acids. Furthermore, the transformation kinetics of inorganic compounds, typical organic compounds and emerging micropollutants are compared and their half-life times under typical water treatment conditions during ClO(2)oxidation are calculated.

Synthesis and pharmacological evaluation of 3-[5-(aryl-[1,3,4]oxadiazole-2-yl]-piperidine derivatives as anticonvulsant and antidepressant agents

In the present study, we have synthesized a series of fifteen nipecotic acid 1,3,4-oxadiazole based hybrids with significant (60-78%) yields. All the compounds were characterized by using different spectroanalytical techniques such as FT-IR, H-1 NMR, C-13 NMR, and elemental analysis. This design strategy was validated by using in vivo anti-epileptic and anti-depressant bioassay models. Anti-convulsant activity was evaluated using subcutaneous pentylenetetrazol (scPTZ) in mice and MES induced seizure. Among a spectrum of activities, three compounds (4i, 4m, and 4n) displayed significant activity against pentylenetetrazole (scPTZ) induced seizures. No disruptions in motor co-ordination were observed in mice pretreated with the test compounds in the rotarod test. Their influence on the safety profile of elevated serum levels of biochemical markers such as hepatic and renal toxicity has been found to be safe. The derivatives also show marked anti-depressant activity, devoid of serotonergic augmentation as assessed using the despair swim test, 5-hydroxytryptophan (5-HTP)-induced head twitch test and learned helplessness test. In silico docking studies targeted on homology modelled GABA transporter 1 (GAT1) protein shows the critical enzyme-ligand interactions leading to the inhibition of the GAT1 transporter. The compound 4m was found to be the most active compound among all the synthesized compounds. (C) 2020 Published by Elsevier B.V. on behalf of King Saud University.
