Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Tetrahedron Letters called A catalyst and additive-free three-component reaction of highly electrophilic azides with cyclic ketones and cycloaliphatic amines. Synthesis of novel N-heteroaryl amidines, Author is Efimov, Ilya; Beliaev, Nikolai; Beryozkina, Tetyana; Slepukhin, Pavel; Bakulev, Vasiliy, which mentions a compound: 4531-54-8, SMILESS is NC1=C([N+]([O-])=O)N=CN1C, Molecular C4H6N4O2, Quality Control of 1-Methyl-4-nitro-1H-imidazol-5-amine.

Highly electrophilic 5-azido-1-methyl-4-nitro-1H-imidazole and sulfonyl azides were demonstrated to react with alicyclic amines and cyclic ketones in the absence of any catalyst or additive to afford novel N-(4-nitroimidazol-5-yl)- or N-sulfonylamidines resp. Based on single crystal X-ray anal., a revision of the previously reported data of Gao and co-workers on the direction of the reaction of sulfonyl azides with endocyclic enamines was made. The reaction of 2,6-diazidopyridine with an enamine, 4-(cyclohex-1-en-1-yl)morpholine, proceeded with cyclization of the azide moiety onto the pyridine C=N bond to form an amidine bearing the tetrazolo[1,5-a]pyridine fragment.

We report characteristics of the cerebrospinal fluid (CSF) pleocytosis (616+/-148 cells/microliter) that occurred in guinea-pigs with definite clinical experimental allergic encephalomyelitis developing 12 to 16 days after sensitization with homologous myelin basic protein. This pleocytosis was not present in the cerebrospinal fluid of a group of animals studied when still healthy, 9 or 10 days after similar sensitization. Eighty-nine per cent of cells in the CSF pleocytosis were small lymphocytes, 8% were larger lymphocytes and the remainder mostly monocytes. Of the lymphocytes, most were E-rosetting or null cells. B-cell markers were uncommon. The cellular patterns in this CSF pleocytosis appear to be similar to those seen in some delayed hypersensitivity responses.
