Background: The poor permeability of the plasma and nuclear membranes to DNA plasmids are two major barriers for the development of these therapeutic molecules. Therefore, success in gene therapy approaches depends on the development of efficient and safe non-viral delivery systems. Objectives: The aim of this study was to investigate the in vitro delivery of plasmid DNA encoding HPV16 E7 gene...

The synthesis of SmCl3(THF)3 from SmCl3.6H2O is described. The reaction of SmCl3(THF)3 with NaBH4 in dry THF gave white microcrystalline tris (tetrahydroborato) tris (tetrahydrofuran) samarium (III), Sm(BH4)3(THF)3. The vibrational and magnetic properties of Sm(BH4)3...

Two Cu(II) complexes, [Cu(L1)2](NO3)2 (1) and [Cu(L2)2] (NO3)2(2), which L1 and L2 Schiff base ligands are 2-(thiophene-2-yl) -1H-imidazo [4,5-f] [1,10] phenanthroline and 2-(furane-2-yl)-1H-imidazo[4,5-f] [1,10] phenenthroline, respectively, were syn...

The first step of electrophilic aromatic substitution reactions generally involves the formation of charge transfer complexes. Tetracyanoethylene (TCNE) in the presence of aromatic amines forms π-type complexes that subsequently lead to tricyanovinylation reaction. Although this kind of reaction was investigated in the past, the spectroscopic characterization of the charge transfer complexes is...

VI.1-HIGH MOLECULAR WEIGHT INORGANIC COMPLEXES Large polymetallic complexes are potentially useful molecules in a variety of areas. Photochemically active compounds are under investigation as efficient photoinitiators for solar-energy conversion, catalysts, and as selective “light-activated anticancer drugs”. On a molecular level, these large organometallic species typically contain light-absor...

Few novel cobalt(II) and copper(II) complexes [M(fmp)3]Cl2, [M(fmp)(bpy)2]Cl2,[M(fmp)(phen)2]Cl2 and [M(fmp)(phen)(bpy)]Cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,IR, electronic, EPR, mass spectra and cyclic voltammetri...

nickel (ii) and copper (ii) complexes of highly unsymmetrical tetradentate schiff base have been synthesized by the template reaction of half-units n-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (hl) and n-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (hl1) with the glyoxalphenylhydrazone. the complexes have been characterized by elemental analyses, conductance, ir, 1h nmr and uv spe...
