3,5-Dinitro-N-(4-nitrophenyl)benzamide
In the title mol-ecule, C(13)H(8)N(4)O(7), the amide fragment has an anti configuration. The mean planes of the two benzene rings form a dihedral angle of 7.78 (4)°. The mean planes of the three nitro groups are twisted by 6.82 (3), 5.01 (4) and 18.94 (7)° with respect to the benzene rings to which they are attached. In the crystal, mol-ecules are linked by weak inter-molecular N-H⋯O hydrogen b...

In the title compound, C(17)H(12)N(2)O(7)S, the dihedral angle between the benzene ring and the naphthyl plane is 26.34 (6)°. The nitro groups make dihedral angles of 40.09 (4) and 37.05 (3)° with the naphthyl plane. In the crystal structure, weak intra- and inter-molecular C-H⋯O inter-actions are observed.
متن کامل3-Cyclohexylsulfanyl-2-(4-methylphenyl)-5,7-dinitro-1H-indole
In the title compound, C(21)H(21)N(3)O(4)S, the cyclo-hexane ring adopts a chair conformation. The nitro and methyl-phenyl groups are all coplanar with the indole ring system. Intra-molecular N-H⋯O and C-H⋯S hydrogen bonds generate S(6) ring motifs. The mol-ecules form R(2) (2)(20) centrosymmetric dimers via inter-molecular C-H⋯O hydrogen bonds. A short O⋯O contact [2.842 (2) Å] is observed in ...

The clinical relevance: The assessment of the antigenicity of an injectable molecule for the human organism requires human patient sera due to the inherent variability of antibodies from person to person, and the inherent variation of bioactivity of antibodies within a single individual. Antibodies produced experimentally in animals give little information with regard to clinical effects of the...

Sarcoidosis is a multisystemic granulomatous disorder of unknown aetiology typically affecting the lungs and lymph nodes. Less frequently, the kidneys may also be affected. Postmortem analysis suggests that 20 percent of patients have histologic changes in the kidney. However, clinical involvement of the kidney is a relatively uncommon condition. Renal failure may occur associated with hypercal...
