Experimental and computational thermochemical study of barbituric acids: structure-energy relationship in 1,3-dimethylbarbituric acid.

María Victoria Roux et al.

The journal of physical chemistry. A, 115(14), 3167-3173 (2011-03-25)

This paper reports an experimental and computational thermochemical study on 1,3-dimethylbarbituric acid. The value of the standard (p° = 0.1 MPa) molar enthalpy of formation in the gas phase at T = 298.15 K has been determined. The energy of

Synthesis of 5-aryl-1,3-dimethyl-6-(alkyl- or aryl-amino) furo [2,3-d]pyrimidine derivatives by reaction between isocyanides and pyridinecarbaldehydes in the presence of 1,3-dimethylbarbituric acid.

Molecular diversity, 15(1), 227-231 (2010-07-14)

5-Aryl-6-(alkyl- or aryl-amino)-1,3-dimethylfuro [2,3-d]pyrimidine derivatives were obtained by in situ reaction alkyl or aryl isocyanides and pyridinecarbaldehyde derivatives in the presence of 1,3-dimethylbarbituric acid in dichloromethane without any prior activation or modifications.

Self-assembled Pd6 open cage with triimidazole walls and the use of its confined nanospace for catalytic Knoevenagel- and Diels-Alder reactions in aqueous medium.

Dipak Samanta et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 18(39), 12322-12329 (2012-08-18)

The two-component self-assembly of a 90° Pd(II) acceptor and a triimidazole donor led to the formation of a water-soluble semi-cylindrical cage with a hydrophobic cavity, which was separately crystallized with hydrophilic- and hydrophobic guests. The parent cage was found to

Determination of low environmental free cyanide concentrations in freshwaters.

Burkhard Knopf et al.

Environmental science and pollution research international, 28(13), 16244-16252 (2020-12-18)

Cyanide compounds are naturally emitted into the environment in low levels by degradation processes or emitted from anthropogenic sources. In surface water, complex cyanide compounds as well as "free cyanide" are present. The latter term covers hydrogen cyanide and cyanide

Barbituric Acid Based Fluorogens: Synthesis, Aggregation-Induced Emission, and Protein Fibril Detection.

Siyang Ding et al.

Molecules (Basel, Switzerland), 25(1) (2019-12-22)

Fluorescent dyes, especially those emitting in the long wavelength region, are excellent candidates in the area of bioassay and bioimaging. In this work, we report a series of simple organic fluorescent dyes consisting of electron-donating aniline groups and electron-withdrawing barbituric

Sequential one-pot bimetallic Ir(III)/Pd(0) catalysed mono-/bis-alkylation and spirocyclisation processes of 1,3-dimethylbarbituric acid and allenes.

Christian Löfberg et al.

Chemical communications (Cambridge, England), (48)(48), 5000-5002 (2006-12-06)

Microwave assisted indirect functionalization of alcohols with 1,3-dimethylbarbituric acid followed by spirocyclisation employing a sequential one-pot Ir(III)/Pd(0) catalysed process, involving the formation of three new C-C bonds, one spirocyclic ring and one di- or tri-substituted exocyclic alkene, is described.

Novel temporin L antimicrobial peptides: promoting self-assembling by lipidic tags to tackle superbugs.

Rosa Bellavita et al.

Journal of enzyme inhibition and medicinal chemistry, 35(1), 1751-1764 (2020-09-23)

The rapid development of antimicrobial resistance is pushing the search in the discovering of novel antimicrobial molecules to prevent and treat bacterial infections. Self-assembling antimicrobial peptides, as the lipidated peptides, are a novel and promising class of molecules capable of

Mechanistic study of in vitro chemical interaction of trimipramine drug with barbituric derivative after its oxidation: Electrochemical synthesis of new dibenzazepine derivative.

Shahram Lotfi et al.

Materials science & engineering. C, Materials for biological applications, 76, 153-160 (2017-05-10)

Electrochemical oxidation of trimipramine in the absence and presence of 1,3 dimethyl barbituric acid as a nucleophile in aqueous solution has been studied using cyclic voltammetry and controlled-potential coulometry electrolysis. Voltammetric studies of electro-oxidation of trimipramine were realized in a

Organocatalytic Michael-Knoevenagel-hetero-Diels-Alder reactions: an efficient asymmetric one-pot strategy to isochromene pyrimidinedione derivatives.

Bor-Cherng Hong et al.

Organic letters, 14(2), 448-451 (2011-12-27)

Synthesis of isochromene pyrimidinedione derivatives having five stereocenters has been achieved by a one-pot Michael-Knoevenagel condensation-inverse-electron-demand hetero-Diels-Alder reaction of α, β-unsaturated aldehydes, olefinic nitroalkanes, and 1,3-dimethylbarbituric acid via a one-pot strategy with excellent diastereo- and enantioselectivities (up to 99% ee).

Multicomponent self-sorting of a Pd7 molecular boat and its use in catalytic Knoevenagel condensation.

Dipak Samanta et al.

Chemical communications (Cambridge, England), 49(39), 4307-4309 (2013-01-09)

Unique three-component self-assembly of a cis-blocked 90° Pd(II) acceptor with a mixture of tri- and tetra-imidazole donors led to the self-sorting of a Pd7 molecular boat with an internal nanocavity, which catalyses the Knoevenagel condensation of a series of aromatic

Enlargement of high density lipoprotein in mice via liver X receptor activation requires apolipoprotein E and is abolished by cholesteryl ester transfer protein expression.

Xian-Cheng Jiang et al.

The Journal of biological chemistry, 278(49), 49072-49078 (2003-08-30)

The factors involved in the generation of larger high density lipoprotein (HDL) particles, HDL1 and HDLc, are still not well understood. Administration of a specific synthetic liver X receptor (LXR) agonist, T0901317, in mice resulted in an increase of not
