Synthesis, Spectral Analysis and Preliminary in Vitro Evaluation of Some Tetrapyrrolic Complexes with 3d Metal Ions

open access: yesMolecules, 2015
In this paper, two tetrapyrrolic complexes, Zn(II)-5-(3-hydroxyphenyl)-10,15,20-tris-(4-acetoxy-3-methoxyphenyl)porphyrin and Cu(II)-5-(3-hydroxyphenyl)-10,15,20-tris-(4-acetoxy-3-methoxyphenyl)porphyrin were synthesized, and characterized from a ...

Application of the electronic spectra of porphyrins for analytical purposes: the effects of metal ions and structural distortions [PDF]

open access: yes, 2013
We investigated the UV-Vis absorption, singlet-1 and singlet-2 fluorescence, as well as the formation of several metalloporphyrins from equilibrial and kinetic aspects in aqueous solution.

Recent insights into the biological functions of liver fatty acid binding protein 1

open access: yesJournal of Lipid Research, 2015
Over four decades have passed since liver fatty acid binding protein (FABP)1 was first isolated. There are few protein families for which most of the complete tertiary structures, binding properties, and tissue occurrences are described in such detail ...

Resonance Raman Interrogation of the Consequences of Heme Rotational Disorder in Myoglobin and its Ligated Derivatives [PDF]

open access: yes, 2008
Resonance Raman spectroscopy is employed to characterize heme site structural changes arising from conformational heterogeneity in deoxyMb and ligated derivatives, i.e., the ferrous CO (MbCO) and ferric cyanide (MbCN) complexes.

Two-Dimensional Molecular Patterning by Surface-Enhanced Zn-Porphyrin Coordination [PDF]

open access: yes, 2009
In this contribution, we show how zinc-5,10,15,20-meso-tetradodecylporphyrins (Zn-TDPs) self-assemble into stable organized arrays on the surface of graphite, thus positioning their metal center at regular distances from each other, creating a molecular ...

Thermodynamic and Experimental Substantiation of the Possibility of Formation and Extraction of Organometallic Compounds as Indicators of Deep Naphthogenesis

open access: yesEnergies, 2023
In this article, typomorphic associations of microelements in carbonaceous caustobioliths and oils are defined as indicators of naphthogenesis based on the analytical survey of the literature and our own research.

Antimicrobial activity of different substituted meso-porphyrin derivatives

open access: yesRomanian Journal of Laboratory Medicine, 2020
The increasing resistance against classical antibiotic treatment forces the researchers to develop novel non-toxic antimicrobial agents. The aim of this study was to determine the antimicrobial properties of seven different porphyrins having distinctive ...

Impact of Fano and Breit-Wigner resonances in the thermoelectric properties of nanoscale junctions [PDF]

open access: yes, 2013
We show that the thermoelectric properties of nanoscale junctions featuring states near the Fermi level strongly depend on the type of resonance generated by such states, which can be either Fano or Breit-Wigner-like.

Consistent force field for metalloporphyrins [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
Molecular mechanics (MM) calculations to analyze the puckering of metalloporphyrins isolated and adsorbed on a graphite layer (0001) as a function of metal ion size and the peripheral substitution are presented.
