(WORLD SCI PUBL CO INCHACKENSACK, 2012)
The new triazene-porphyrin dye 5-(1-(4-phenyl)-3-(4-nitrophenyl)triazene)-10,15,20-triphenylporphyrin, encompassing a reactive protonated triazene moiety, was prepared starting from meso-tetraphenylporphyrin (H2TPP), first ...
Triazenos: clivagem do DNA, atividade antibacteriana e toxicidade frente à Artemia salina Leach
(Universidade Federal de Santa MariaBRAnálises Clínicas e ToxicológicasUFSMPrograma de Pós-Graduação em Ciências Farmacêuticas, 2007-12-13)
In this work, six triazene compounds are assayed to DNA cleavage activity. The same six triazenes and the drug Asercit® (dacarbazine) are assayed to antibacterial activity and toxicity to Artemia salina Leach.: ...
Mono-, bis- e tris-triazenos, tetrazeno e complexos de Cu(I), Ag(I), Au(I), Cu(II), Ni(II), Pd(II) E Cu(III): síntese, caracterização, estrutura cristalina, atividades antitumoral, antibacteriana e de clivagem do DNA in vitro
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2013-01-31)
Multi-nitrogenated ligands are versatile coordinating ligands to the transition metals. In this
work, mono- and bis-triazenes, a tris-triazene, a tetrazenide and twelve metal complexes were
synthesized, including the ...
Estrutura cristalina e molecular de complexos triazenidos n-óxidos de Cu(II), Ni(II) e Au(I) e estudo dos seus derivados imobilizados em MCM-41
(Universidade Federal de Santa MariaBREngenharia de ProcessosUFSMPrograma de Pós-Graduação em Engenharia de Processos, 2013-03-14)
Triazenes are a class of chemical compounds that presents three atoms of nitrogen bonded each other in sequence on a open chain. An analogue of these generics monocatenade Triazenes are Triazenes 1-oxide, used in many areas ...
Avaliação da auto-associação molecular de complexos metálicos com ligantes triazenidos derivados do 1,3-bis(fenil)triazeno
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2007-09-13)
This work presents the synthesis and the investigation of the crystalline and molecular structure of 1,3-bis(2-methoxy-4-nitrophenyl)triazene ethanol and seventeen new mononuclear or binuclear complexes of Cu(I), Cu(II), ...
Síntese e caracterização de triazenos e complexos com Hg(II) incluindo arranjos supramoleculares
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2011-10-14)
This work presents the synthesis of new compounds and their triazenes complexes of
mercury(II). Triazenes have three nitrogen atoms connected in sequence [ N=N N(H) ] and, when
deprotonated, they become good Lewis bases ...
Bichromophoric behavior of nitrophenyl-triazene anions: a resonance Raman spectroscopy investigation
(JOHN WILEY & SONS LTD, 2008)
Highly delocalized molecular frameworks with intense charge transfer transitions, known as push-pull systems, are of central interest in many areas of chemistry, as is the case of nitrophenyl-triazene derivatives. The ...
