Síntese de novos pirróis derivados de aminocumarinas
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2018-07-19)
In this work, the synthesis of new pyrroles derived from aminocoumarins was
developed. First, the synthesis of pyrroles derived from 4-amino-2H-chromen-2-one
was carried out by the Paal-Knorr and Clauson-Kaas reactions, ...
Vesicles in electric fields: Some novel aspects of membrane behavior
(Royal Soc Chemistry, 2009-01-01)
This review focuses on the effects of electric fields on giant unilamellar vesicles, a cell-size membrane system. We describe various types of behavior of vesicles subjected to either alternating fields or strong direct ...
Green Synthesis of Pyrrole Derivatives
(Bentham Science Publishers, 2017-01)
Background: Pyrroles are organic cyclic compounds with an extensive and fascinating chemistry. These compounds have a wide structural variety and they are an important basis in technological development as they can be used ...
Síntese de N-glicosilssulfonamidas, de aza-açúcares derivados de N-Acetilglicosamina e D-Glicose e tentativa de síntese de inibidores potenciais de quitinases
(Universidade Federal de Minas GeraisUFMG, 2015-07-08)
In Medicinal Chemistry the enzymes of pathogens like fungi or bacteria are considered good molecular targets for the development of new drugs and the inhibition of these enzymes can result in pharmacological action trough ...
Novel bifunctional mesoporous catalysts based on preyssler heteropolyacids for green pyrrole derivative synthesis
(Molecular Diversity Preservation International, 2018-10-26)
In this paper, we report the synthesis of Preyssler heteropolyacids supported on mesoporous alumina in order to obtain materials with acid–base properties. A series of pyrrole derivatives were synthesized using a suitable ...
Synthesis of tuneable amphiphilic-modified polyketone polymers, their complexes with 5,10,15,20-tetrakis-(4-sulfonatophenyl)porphyrin, and their role in the photooxidation of 1,3,5-triphenylformazan confined in polymeric nanoparticles
(Elsevier Ltd, 2019)
A series of amphiphilic polymers bearing aliphatic secondary amines and hydroxyl groups have been synthesized showing different hydrophilic/hydrophobic balance. The synthesis is performed through the Paal-Knorr modification ...
Totally Organic Redox-Active pH-Sensitive Nanoparticles Stabilized by Amphiphilic Aromatic Polyketones
(2018)
Amphiphilic aromatic polymers have been synthesized by grafting aliphatic polyketones with 4-(aminomethyl)benzoic acid at different molar ratios via the PaalKnorr reaction. The resulting polymers, showing diketone conversion ...
Derivados pirazolínicos inéditos causam antinocicepção em camundongos no teste da formalina
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2004-07-29)
The discovery of pyrazole derivatives dates back to 1884, when the German chemist Ludwig Knorr attempted to synthesize quinoline derivatives with antipyretic activity and accidentally obtained antipyrine, a pyrazolinone, ...
