Ethyl-enediaminium dinicotinate.

ABSTRACT: In the title compound, C(2)H(10)N(2) (2+)·2C(6)H(4)NO(2) (-), the cation lies on an inversion centre. The asymmetric unit is composed of one nicotinate anion and one half ethyl-enediaminium cation. All the amino H atoms are involved in N-H?O and N-H?N hydrogen bonds. These hydrogen bonds link the ionic units into a three-dimensional network. In addition, ?-? inter-actions between pyridine rings [centroid-centroid distance = 3.6037?(7)?Å] further stabilize the crystal structure.

In the title compound, C(2)H(10)N(2) (2+)·2C(6)H(4)NO(2) (-), the cation lies on an inversion centre. The asymmetric unit is composed of one nicotinate anion and one half ethyl-enediaminium cation. All the amino H atoms are involved in N-H⋯O and N-H⋯N hydrogen bonds. These hydrogen bonds link the ionic units into a three-dimensional network. In addition, π-π inter-actions between pyridine rings [centroid-centroid distance = 3.6037 (7) Å] further stabilize the crystal structure. ...[more]

Project description:In the title compound, C(2)H(10)N(2) (2+)·0.5(C(2)O(4))(2-)·NCS(-), the ethyl-enediaminium dication adopts a (+)-synclinal conformation with an N-C-C-N torsion angle of 62.64 (15)°. The oxalate dianion lies across an inversion centre. In the crystal structure, the ions are linked through N-H⋯N, N-H⋯O and C-H⋯S hydrogen bonds, leading to the formation of a three-dimensional network.

1,2-Ethyl-enediaminium bis-(2-benzamido-benzoate).

Project description:In the title salt, C2H10N2 (2+)·2C14H10NO3 (-), the ethyl-ene-diaminium dication lies on an inversion centre. In the anion, the benzene rings make a dihedral angle of 33.87 (9)° and intramolecular N-H⋯O and C-H⋯O hydrogen bonds occur. All the amino H atoms are involved in N-H⋯O hydrogen bonds. These hydrogen bonds link the ionic units into a three-dimensional network. In addition, the crystal structure also features weak C-H⋯O inter-actions.

o-Phenyl-enediaminium chloride nitrate.

Project description:In the title mol-ecular salt, C6H10N2 (2+)·NO3 (-)·Cl(-), the complete cation is generated by a crystallographic mirror plane. The complete nitrate ion is also generated by reflection, with the N atom and one O atom lying on the mirror plane; the chloride ion also lies on the reflection plane. In the crystal, the components are linked by N-H⋯Cl and N-H⋯(N,O) hydrogen bonds, forming (001) layers with the benzene rings projecting into the inter-layer regions. The layers are linked by weak C-H⋯O hydrogen bonds, generating a three-dimensional network.

Poly[ethyl-enediaminium [di-μ-aqua-(μ(6)-benzene-1,2,4,5-tetra-carboxyl-ato-κO,O:O,O:O:O,O:O:O,O)dithallium(I)]].

Project description:The title compound, {(C(2)H(10)N(2))[Tl(2)(C(10)H(2)O(8))(H(2)O)(2))]}(n), was prepared using (enH(2))(2)(btc)·2H(2)O and thallium(I) nitrate (en = ethyl-enediamine and btcH(4) = benzene-1,2,4,5-tetra-carboxylic acid). The enH(2) cation and btc ligand are each located on an inversion centre. The Tl(I) atom is seven-coordinated by three btc ligands and two water mol-ecules in an irregular geometry due to the stereochemically active lone pair on the Tl centre. The water mol-ecule and btc ligand are bonded to the Tl atoms in μ- and μ(6)-forms, respectively, leading to a three-dimensional structure. The crystal structure involves O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and also a Tl⋯π inter-action of 3.537 (1) Å.

Gene expression changes in human cardiomyocytes exposed to VX (O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothiolate)

Project description:Organophosphorus compounds induce cardiotoxicity through currently unknown mechanisms, which need to be unraveled by a comprehensive and systematic approach such as genome-wide gene expression analysis. We used microarrays to study gene expression changes in human cardiomyocytes after exposure to VX, and identified pathways underlying these changes. Human cardiomyocytes were exposed to sublethal concentrations (0, 0.1, 10 μM) of VX. RNA were extracted at different timepoints (0, 6, 24, 72 h) after VX exposure and hybridized to Affymetrix microarrays. Four biological repeats were used for each condition.

Project description:Organophosphorus compounds induce hepatotoxicity through currently unknown mechanisms, which need to be unraveled by a comprehensive and systematic approach such as genome-wide gene expression analysis. We used microarrays to study gene expression changes in human hepatocytes after exposure to VX, and identified pathways underlying these changes. Human hepatocytes were exposed to sublethal concentrations (0, 0.1, 10 μM) of VX. RNA were extracted at different timepoints (0, 6 h) after VX exposure and hybridized to Affymetrix microarrays. Four biological repeats were used for each condition.

Gene expression changes in human neural cells exposed to VX (O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothiolate)

Project description:Organophosphorus compounds may induce neurotoxicity through mechanisms other than the cholinergic pathway, which need to be unraveled by a comprehensive and systematic approach such as genome-wide gene expression analysis. We used microarrays to study gene expression changes in human neural cells after exposure to VX, and identified pathways underlying these changes. Human neural cells were exposed to sublethal concentrations (0, 0.1, 10 μM) of VX. RNA were extracted at different timepoints (0, 6, 24, 72 h) after VX exposure and hybridized to Affymetrix microarrays. Four biological repeats were used for each condition.
