Crystal structure of 1,2-bis­[(2-tert-butyl­phen­yl)imino]­ethane

The whole molecule of the title compound, C22H28N2, (I), is generated by inversion symmetry. The mol-ecule is rather similar to that of 2,3-bis-[(2-tert-butyl-phen-yl)imino]-butane, (II), a di-imine ligand comprising similar structural features [Ferreira et al. (2006 ▶). Acta Cryst. E62, o4282-o4284]. Both ligands crystallize with the -N=C(R)-C(R)=N- group around an inversion centre, in a trans...

Crystal structure of 4,4′-(ethane-1,2-di­yl)bis­(2,6-di­bromo­aniline)

In the title compound, C14H12Br4N2, the mol-ecule lies across an inversion center and hence the benzene rings are strictly coplanar. In the crystal, mol-ecules are linked by N-H⋯N and weak N-H⋯Br hydrogen bonds, forming a two-dimensional network parallel to (101). In addition, type II Br⋯Br inter-actions [3.625 (4) Å] complete a three-dimensional supra-molecular network.

Nitrous oxide-induced vitamin B(12) deficiency.

Two patients with asymptomatic vitamin B(12) deficiency developed a peripheral neuropathy 6-7 weeks after exposure to nitrous oxide during general anaesthesia, and 3 and 11 days after receiving cyclophosphamide. The serum B(12) concentration was less than 20 pmol/l and the symptoms resolved after B(12) replacement. We believe that the neurological symptoms were triggered by exposure to nitrous ...

Interleukin 12 Primes Macrophages for Nitric Oxide

Interleukin-12 (IL-12) is a recently described iminunoregulatory cyto kine with potent therapeutic activity in various preclinical models of infectious or malignant disease. As part of our ongoing evaluation of potential mechanisms accounting for the potent antitumor activity of IL-12,wehaveinvestigatedtheinfluenceof IL-12administrationontotal serum nitrate/nitrite (NO@)levels and the productio...
