A simple method for the rapid synthesis of 2-amino-7,7-dimethyl-5-oxo-1,4-diaryl-hexahydroquinoline-3-carboxamide derivatives

Simple synthesis of oxoquinoline carboxamide derivatives via one-pot, multi-component reaction of enaminones derived from the addition of dimedone to various anilines with aromatic aldehydes and cyanoacetamide is described. Optimal reaction conditions for the synthesis of products were obtained, when EtOH/H2O (1:1) was used as the solvent at 80 degrees C, in the presence of piperidine as the catalyst. The reactions are completed within 5-25 min, in good to high yields (74-85%). This protocol involves Michael reaction, imine-enamine tautomerization, and cyclization sequences. The structures of products were deduced from their IR, mass, H-1 NMR, and C-13 NMR spectra. This method includes some important aspects including simple operation under mild conditions, easy accessibility of reactants, workup procedure, high atom economy, and the use of ethanol/water as a green media.

Alkaline polymer electrolyte fuel cells stably working at 80 degrees C

Alkaline polymer electrolyte fuel cells are a new class of polymer electrolyte fuel cells that fundamentally enables the use of nonprecious metal catalysts. The cell performance mostly relies on the quality of alkaline polymer electrolytes, including the ionic conductivity and the chemical/mechanical stability. For a long time, alkaline polymer electrolytes are thought to be too weak in stability to allow the fuel cell to be operated at elevated temperatures, e.g., above 60 degrees C. In the present work, we report a progress in the state-of-the-art alkaline polymer electrolyte fuel cell technology. By using a newly developed alkaline polymer electrolyte, quaternary ammonia poly (N-methyl-piperidine-co-p-terphenyl), which simultaneously possesses high ionic conductivity and excellent chemical/mechanical stability, the fuel cell can now be stably operated at 80 degrees C with high power density. The peak power density reaches ca. 1.5 W/cm(2) at 80 degrees C with PVC catalysts used in both the anode and the cathode. The cell works stably in a period of study over 100 h.

Catalytic Sulfone Upgrading Reaction with Alcohols via Ru(II)

Sulfones and sulfonamides with an a-CH bond can be easily alkylated by aliphatic alcohols to add the carbon skeleton of the alcohol via a one-step, Ru(II)-catalyzed redox neutral reaction. The reaction requires a substoichiometric amount of base and produces only water as a byproduct. Several pharmaceutically relevant functional groups such as piperidine, morpholine, etc. are well-tolerated under the reaction conditions to give higher value-added products in one step from widely available substrates. The reaction proceeds through a sulfone carbanion addition to an in-situ-generated aldehyde formed via catalytic dehydrogenation and subsequent catalyst-mediated replacement of the secondary alcohol by hydrogen.

Synthesis and biological activity of novel tert-butyl and tert-pentylphenoxyalkyl piperazine derivatives as histamine H3R ligands

As a continuation of our search for novel histamine H-3 receptor ligands, a series of twenty four new tertbutyl and tert-pentyl phenoxyalkylamine derivatives (2-25) was synthesized. Compounds with three to four carbon atoms alkyl chain spacer were evaluated for their binding properties at human histamine H-3 receptor (hH(3)R). The highest affinities were observed for 4-pyridyl derivatives 4, 10, 16 and 22 (K-i = 16.0 120 nM). As it has been shown in docking studies, those specific heteroaromatic 4-N piperazine substituents might interact with one of the key receptor interacting amino acids. Moreover, the most promising compounds exhibited anticonvulsant activity in the maximal electroshock-induced seizure (MES) model in mice. Furthermore, the blood-brain barrier penetration, the functional H3R antagonist potency as well as the pro-cognitive properties in the passive avoidance test were demonstrated for compound 10. In order to estimate drug-likeness of compound 10, in silico and experimental evaluation of metabolic stability in human liver microsomes was performed. In addition, paying attention to the results obtained within this study, the 4-pyridyl-piperazino moiety has been established as a new bioisosteric piperidine replacement in H3R ligands.

p-Substituted Tris(2-pyridylmethyl)amines as Ligands for Highly Active ATRP Catalysts: Facile Synthesis and Characterization

A facile and efficient two-step synthesis ofp-substituted tris(2-pyridylmethyl)amine (TPMA) ligands to form Cu complexes with the highest activity to date in atom transfer radical polymerization (ATRP) is presented. In the divergent synthesis,p-Cl substituents in tris(4-chloro-2-pyridylmethyl)amine (TPMA(3Cl)) were replaced in one step and high yield by electron-donating cyclic amines (pyrrolidine (TPMA(PYR)), piperidine (TPMA(PIP)), and morpholine (TPMA(MOR))) by nucleophilic aromatic substitution. The [Cu-II(TPMA(NR2))Br](+)complexes exhibited larger energy gaps between frontier molecular orbitals and >0.2 V more negative reduction potentials than [Cu-II(TPMA)Br](+), indicating >3 orders of magnitude higher ATRP activity. [Cu-I(TPMA(PYR))](+)exhibited the highest reported activity for Br-capped acrylate chain ends in DMF, and moderate activity toward C-F bonds at room temperature. ATRP ofn-butyl acrylate using only 10-25 part per million loadings of [Cu-II(TPMA(NR2))Br](+)exhibited excellent control.

Lock and chop: A novel method for the generation of a PICK1 PDZ domain and piperidine-based inhibitor co-crystal structure

The membrane protein interacting with kinase C1 (PICK1) plays a trafficking role in the internalization of neuron receptors such as the amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA) receptor. Reduction of surface AMPA type receptors on neurons reduces synaptic communication leading to cognitive impairment in progressive neurodegenerative diseases such as Alzheimer disease. The internalization of AMPA receptors is mediated by the PDZ domain of PICK1 which binds to the GluA2 subunit of AMPA receptors and targets the receptor for internalization through endocytosis, reducing synaptic communication. We planned to block the PICK1-GluA2 protein-protein interaction with a small molecule inhibitor to stabilize surface AMPA receptors as a therapeutic possibility for neurodegenerative diseases. Using a fluorescence polarization assay, we identified compound BIO124 as a modest inhibitor of the PICK1-GluA2 interaction. We further tried to improve the binding affinity of BIO124 using structure-aided drug design but were unsuccessful in producing a co-crystal structure using previously reported crystallography methods for PICK1. Here, we present a novel method through which we generated a co-crystal structure of the PDZ domain of PICK1 bound to BIO124.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13360-65-1 is helpful to your research. Recommanded Product: 13360-65-1.

Efficient synthesis of aurone Mannich bases and evaluation of their antineoplastic activity in PC-3 prostate cancer cells

An efficient method for regioselective synthesis of C-7 Mannich bases of 6-hydroxyaurones was accomplished by the N,N-dialkylaminomethylation using aminals prepared from dimethylamine, dipropylamine, bis(2-methoxyethyl)amine, N-methylbutylamine, N-methylbenzylamine, morpholine, piperidine, and 1-methylpiperazine. Further transformation of 7-(N,N-dialkylamino)methyl group in these aurones led to formation of C-7 acetoxymethyl and methoxymethyl derivatives of 6-hydroxyaurones, some of which showed promising inhibition of PC-3 prostate cancer cell proliferation in the high nanomolar to low micromolar range that exceeded that of cisplatin.

Conventional versus microwave assisted synthesis, molecular docking and enzyme inhibitory activities of new 3,4,5-trisubstituted-1,2,4-triazole analogues

N-(Substituted)-5-(1-(4-methoxyphenylsulfonyl)piperidin-4-yl)-4H-1,2,4-triazol-3-ylthio) acetamide were synthesized by following conventional as well as microwave assisted protocol through five consecutive steps under the impact of various reaction conditions to control the reaction time and the yield of product. Starting from 4-methoxybenzenesulfonyl chloride and ethyl isonipecotate, product 3 was obtained which was converted into product 4 by treating with hydrazine hydrate. In step 3, the product 4 was refluxed with methyl isothiocyanate and KOH to yield compound 5 which was finally treated with variety of N-substituted acetamides to yield an array of different new compounds (8a-k). These synthesized compounds were evaluated for their inhibition potential against bovine carbonic anhydrase (bCA-II), acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. Compound 8g demonstrated good activity against bCA-II, AChE and BChE with IC50 values of 8.69 +/- 0.38 mu M, 11.87 +/- 0.19 mu M and 26.01 +/- 0.55 mu M respectively.

Crystallographic evidence for unintended benzisothiazolinone 1-oxide formation from benzothiazinones through oxidation

1,3-Benzothiazin-4-ones (BTZs) are a promising new class of drugs with activity against Mycobacterium tuberculosis, which have already reached clinical trials. A product obtained in low yield upon treatment of 8-nitro-2-(piperidin-1-yl)-6-(trifluoromethyl)-4H-benzothiazin-4-one with 3-chloroperbenzoic acid, in analogy to a literature report describing the formation of sulfoxide and sulfone derived from BTZ043 [Tiwari et al. (2015). ACS Med. Chem. Lett. 6, 128-133], is a ring-contracted benzisothiazolinone (BIT) 1-oxide, namely, 7-nitro-2-(piperidine-1-carbonyl)-5-(trifluoromethyl)benzo[d]isothiazol-3(2H)-one 1-oxide, C14H12F3N3O5S, as revealed by X-ray crystallography. Single-crystal X-ray analysis of the oxidation product originally assigned as BTZ043 sulfone provides clear evidence that the structure of the purported BTZ043 sulfone is likewise the corresponding BIT 1-oxide, namely, 2-[(S)-2-methyl-1,4-dioxa-8-azaspiro[4.5]decane-8-carbonyl]-7-nitro-5-(trifluoromethyl)benzo[d]isothiazol-3( 2H)-one 1-oxide, C17H16F3N3O7S. A possible mechanism for the ring contraction affording the BIT 1-oxides instead of the anticipated constitutionally isomeric BTZ sulfones and antimycobacterial activities thereof are discussed.

Quaternary aminocomplex morpholine, piperidine and pyridine salts with oleic acid were obtained in acid medium, their composition and structure defined. It has been proved that in an acidic medium the protonation of nitrogen atoms of these heterocyclic amines occurs in all cases. Heterocyclic amines are protonated and ligands occupy the outer sphere as cations. All three nitrogen-containing heterocyclic amines are protonated under special conditions with oleic acid and form complex salts in the form of a quaternary amine. The salts obtained are readily soluble in various polar and nonpolar solvents. 75% methanol solutions were prepared from the resulting complex salts and new composite mixtures obtained on their basis.
