A series of novel ligustrazine-benzoic acid derivatives were synthesized and evaluated for their protective effect against cobalt chloride-induced neurotoxicity in differentiated PC12 cells. Combining hematoxylin and eosin staining, we found compound that (3,5,6-trimethylpyrazin-2-yl)methyl 3-methoxy-4-[(3,5,6-trimethylpyrazin-2-yl)methoxy]benzoate (4a) displayed promising protective effect on ...

The complexes of divalent Cobalt with bis(2,6-diacetyl pyridine monoxime)1,2-diiminobenzene have been prepared separately in presence of respective salts. The general molecular formula of the complexes have been found to be [Co(L)]X2 where L=Bis(2,6-diacetyl pyridine monoxime)1,2-di-iminobenzene, X=chloride, bromide, sulphate, perchlorate, nitrate, acetate ions, On the characterisation of the c...

the structural and electrical properties of polyaniline-cobalt sulphate nanocomposite prepared by chemical method.polyaniline-cobalt sulphate nanocomposites were synthesized by the cobalt sulphate and ammonium persulphate and aniline.this paper reports on chemical technique using for synthesis of cobalt nanoparticles in the composite bridge is aniline. electrical conductivity of polyaniline wit...

The title compound, [CoCl(2)(C(11)H(15)N(3)O(2)Si)(2)]·C(3)H(7)NO, was synthesized from 5-nitro-1-trimethyl-silylmethyl-1H-benzimid-azole and cobalt(II) chloride in dimethyl-formamide. The Co(II) atom is coordinated in a distorted tetra-hedral environment by two Cl atoms and two N atoms. In the crystal structure, there are a number of C-H⋯Cl and C-H⋯O hydrogen-bonding inter-actions between symm...

Cobalt chloride can be injected into an identified nerve cell body in an insect ganglion and reacted with ammonium sulfide to stain the soma and its branches with a black precipitate. The stained cell body and its branches throughout the neuropil are visible in both the light and electron microscope. In whole mount preparations, the resolution of neurites within the neuropil is of a quality tha...

We present a study of the structural and thermomechanical properties of lyotropic phase in the quasi ternary system made of Cetylpyridinium chloride (CPCl)/hexanol/salt water (0.9 % by mass) with and without cobalt microparticles. Phase transition temperatures of the structural sequence isotropic L 1/nematic calamitic Nc ,/hexagonal H have been determined by differential scanning microcalorimet...

In the title compound, (C(5)H(7)N(2))(2)[CoCl(4)], the cobalt(II) ion is coordinated by four chloride ions in a slightly distorted tetra-hedral geometry. The crystal packing is stabilized by inter-molecular N-H⋯Cl hydrogen bonding, forming a three-dimensional network. The crystal was a non-merohedral twin emulating tetra-gonal symmetry, but being in fact ortho-rhom-bic.
