The PspGI restriction-modification system recognizes the sequence CCWGG. R.PspGI cuts DNA before the first C in the cognate sequence and M.PspGI is thought to methylate N4 of one of the cytosines in the sequence. M.PspGI enhances fluorescence of 2-aminopurine in DNA if it replaces the second C in the sequence, while R.PspGI enhances fluorescence when the fluorophore replaces adenine in the cent...

A new triple-decker dinuclear sandwich-type dysprosium complex based on both the phthalocyanine ligand and the tetradentate Schiff base ligand was synthesized, which is of interest for synthetic chemistry and also shows single-molecule magnetic behaviour.

Schiffbase was obtained by condensation of camphor with 4-amino-phenol .The charge transfer complex of the Schiff base as a donor molecule with picric acid as acceptor molecule in methanol were estimated. Schiff-base compound and charge transfer complex were identified by elemental analysis, infrared spectra and UV-visible spectra.The physical parameters of the CT complex were calculated by app...

The mercury (II) complex, Hg (Meca2en)I2 (1), containing bidentate Schiff base ligand  Meca2en = N,N′-bis[(E)-2-benzylidenepropylidene]ethane-1,2-diamine, has been synthesized and characterized by elemental analyses (CHN) and 1H-NMR spectroscopy. The crystal structure of 1 was determined using single-crystal X-ray diffraction. Structural investigation shows that 1 crystallizes in a monoclinic s...

We have prepared supramolecular systems of chiral Schiff base Ni(II), Cu(II), Zn(II) complexes and colloidal gold nanoparticles (AuNP) of 10 nm diameters. They demonstrated that direct adsorption of chiral Schiff base metal complex on the surface of AuNP owing to observation of clear induced CD spectra for the first time. We observed and discussed induced CD bands on AuNP from chiral Schiff bas...

In the mononuclear complex mol-ecule of the title compond, [ZnCl(2)(C(18)H(18)N(2)O)(2)]·2C(18)H(18)N(2)O, the Zn atom, which lies on a twofold rotation axis, is coordinated by phenolate O atoms in a tetra-hedral coordination geometry. The coordinated Schiff base uses its indole NH donor site to form a hydrogen bond to the negatively charged phenolate O atom of the uncoordinated zwitterionic Sc...

in this study, we synthesis one-dimensional (1d) manganese(iii) schiff base coordination polymer [mn(brsalophen)(μ1,3-n3)]n by reaction of mncl2·6h2o and tetradentate schiff base ligand brsalophen at the presence of nan3 in methanol and characterized by elemental analyses (chn) and ft-ir spectroscopy. it was used as a new precursor to prepare spinel type manganese oxide nanowires by a facile so...

The visual pigment rhodopsin is unique among the G protein-coupled receptors in having an 11-cis retinal chromophore covalently bound to the protein through a protonated Schiff base linkage. The chromophore locks the visual receptor in an inactive conformation through specific steric and electrostatic interactions. This efficient inverse agonist is rapidly converted to an agonist, the unprotona...

Metal complexes of Cu (II), Co (II), Ni (II) and Zn (II) of Schiff based derived from 5-bromo-2hydroxybenzaldehyde and 4-nitobenzenesulfonamide have been prepared and characterized on the basis of physical characteristics, micro-analytical data, H NMR, FTIR spectrum and electronic data. The spectrum data 1 exhibit coordination of Schiff base with metal through imine nitrogen and oxygen atom and...

A Co(II) quaterpyridine-type complex has been prepared via a one-pot transformation of a 2,2'-bipyridine Schiff-base ligand in the presence of a Lewis acidic metal salt.
