Generation and Alkylation of alpha-Carbamyl Radicals via Organic Photoredox Catalysis

Strategies for the direct C-H functionalization of amines are valuable as these compounds comprise a number of pharmaceuticals, agrochemicals and natural products. This work describes a novel method for the C-H functionalization of carbamate-protected secondary amines via a-carbamyl radicals generated using photoredox catalysis. The use of the highly oxidizing, organic acridinium photoredox catalyst allows for direct oxidation of carbamate-protected amines with high redox potentials to give the corresponding carbamyl cation radical. Following deprotonation, the resultant open-shell species can be intercepted by a variety of Michael acceptors to give elaborate alpha-functionalized secondary amines. The reaction proceeds under mild conditions without the requirement of exogenous redox mediators or substrate prefunctionalization. Additionally, we were able to showcase the utility of this methodology through the enantioselective synthesis of the indolizidine alkaloid, (+)-monomorine I.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 124172-53-8.

Structure-activity relationships for a series of (Bis(4-fluorophenyl) methyl)sulfinylethyl-aminopiperidines and -piperidine amines at the dopamine transporter: Bioisosteric replacement of the piperazine improves metabolic stability

Despite considerable efforts to develop medications to treat psychostimulant use disorders, none have proven effective, leaving an underserved patient population and unanswered questions as to what mechanism(s) of action should be targeted for developing pharmacotherapies. Atypical dopamine transporter (DAT) inhibitors, based on (+/-)modafinil, have shown therapeutic potential in preclinical models of psychostimulant abuse. However, metabolic instability among other limitations to piperazine analogues 1-3 have impeded further development. Herein, bioisosteric substitutions of the piperazine ring were explored with a series of aminopiperidines (A) and piperidine amines (B) wherein compounds with either a terminal tertiary amine or amide were synthesized. Several lead compounds showed high to moderate DAT affinities and metabolic stability in rat liver microsomes. Aminopiperidines 7 (DAT K-i = 50.6 nM), 21b (DAT K-i = 77.2 nM) and 33 (DAT K(i)Elsevier = 30.0 nM) produced only minimal stimulation of ambulatory activity in mice, compared to cocaine, suggesting an atypical DAT inhibitor profile.

Development of a novel radiobromine-labeled sigma-1 receptor imaging probe

Introduction: Sigma-1 receptor is a target for tumor imaging. In a previous study, we synthesized a vesamicol analog, (+)-2-[4-(4-bromophenyl)piperidino]cyclohexanol [(+)-pBrV], with a high affinity for sigma-1 receptor, and synthesized radiobrominated (+)-pBrV. This radiobrominated (+)-pBrV showed high tumor uptake in tumor-bearing mice; however, radioactivity accumulation in normal tissues, such as the liver, was high. We assumed that the accumulation of (+)-pBrV in the non-target tissues was partially derived from its high lipophilicity; therefore, we synthesized and evaluated (+)-4-[1-(2-hydroxycyclohexyl)piperidine-4-yl]-2-bromophenol [(+)-BrV-OH], which is a more hydrophilic compound. Although we aimed to develop a PET tracer using( 76)Br, in these initial studies, we used(77)Br because of its longer half-life. Methods: (+)-[Br-77]BrV-OH was synthesized using the chloramine-T method with a radiochemical purity of 95%. Lipophilicity and affinity for sigma-1 receptor of (+)-[Br-77]BrV-OH were determined, and biodistribution experiments were performed. We also performed an in vivo blocking study by co-injecting excess amounts of the sigma-1 receptor ligand, SA4503, into mice. Results: The lipophilicity and affinity for sigma-1 receptor of (+)-[Br-77]BrV-OH were lower than those of (+)-[Br-77]pBrV. (+)-[Br-77]BrV-OH also showed high tumor uptake in biodistribution experiments in DU-145 tumor-bearing mice,. Although (+)-[Br-77]pBrV was retained in most tissues, (+)-[Br-77]BrV-OH was cleared from these tissues. In blocking studies, the co-injection of SA4503 significantly decreased the tumor uptake of (+)-[Br-77]BrV-OH. Conclusion: These results indicate that (+)-[Br-76]BrV-OH has potential as a PET probe for sigma-1 receptor imaging. (C) 2018 Elsevier Inc. All rights reserved.

C-H Bond Activation for the Synthesis of Heterocyclic Atropisomers Yields Hedgehog Pathway Inhibitors

Axially chiral 4-arylisoquinolones are endowed with pronounced bioactivity, and methods for their efficient synthesis have gained widespread attention. However, enantioselective synthesis of axially chiral 4-arylisoquinolones by means of C-H activation has not been reported to date. Described here is a rhodium (III)-catalyzed C-H bond activation and annulation for the atroposelective synthesis of axially chiral 4-arylisoquinolones. The method employs chiral cyclopentadienyl ligands embodying a piperidine ring as backbone and yields the atropisomers with good to excellent yields and enantioselectivity. Biological relevance of the 4-arylisoquinolones was demonstrated by their investigation in different cellular assays, leading to the discovery of novel non-SMO (SMO = smoothened) binding Hedgehog pathway inhibitors.

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.

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.

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.

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.

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.
