In the title compound, C(20)H(14)N(2), the carbazole ring system is essentially planar (r.m.s. deviation = 0.187 Å) and is inclined at an angle of 54.33 (4) ° with respect to the benzene ring. The crystal packing is stabilized by weak C-H⋯N and C-H⋯π inter-actions.

The S-N(H)-N=C linkage in the title mol-ecule, C(22)H(18)N(2)O(2)S, is non-planar [torsion angle = 30.6 (1)°] as the amino N atom is pyramidally coordinated. In the crystal, the amino group acts as a hydrogen-bond donor to an O atom of an adjacent mol-ecule, generating chains running parallel to the b axis.

Pk -factorization of a complete bipartite graph for k, an even integer was studied by H. Wang [1]. Further, Beiling Du [2] extended the work of H.Wang, and studied the P2k-factorization of complete bipartite multigraph. For odd value of k the work on factorization was done by a number of researchers[3,4,5]. P3-factorization of complete bipartite graph was studied by K.Ushio [3]. P5-factorizatio...

Originally reported to be associated with a low-grade mature B-cell phenotype with plasmacytoid differentiation such as lymphoplasmacytic lymphoma, multiple myeloma/ plasma cell leukemia and chronic lymphocytic leukemia. However, the relatively frequent occurrence in diffuse large B-cell lymphoma, with or without a preceding faze of a low-grade lymphoma, suggests that this chromosomal aberratio...

recent reports have indicated different effects of immunostimulatory sequences containing cpg-oligodeoxynucleotides (odn) on various immune cells. however, the exact role of cpg-odn in the human gut is unclear. in the present study, we assessed potential effects of cpg-odn on non lymphoid cell (intestinal epithelial cell line ht-29) on a dose-response and time-course basis. intestinal epithelia...
