In the title compound, C(23)H(19)N(8)O(+)·BF(4) (-), one pyridine N atom is protonated. Two intra-molecular N-H⋯N hydrogen bonds occur. In the crystal, inter-molecular N-H⋯N hydrogen bond links neighboring C(23)H(19)N(8)O(+) units into cyclic supra-molecular dimers while C-H⋯O hydrogen bonds link the C(23)H(19)N(8)O(+) units into a two-dimensional supra-molecular network structure.
For n ≤ 27 we present exact values for the maximum number h(n) of halving lines and eh(n) of halving pseudolines, determined by n points in the plane. For this range of values of n we also present exact values of the rectilinear cr(n) and the pseudolinear e cr(n) crossing number of the complete graph Kn. eh(n) and e cr(n) are new for n ∈ {14, 16, 18, 20, 22, 23, 24, 25, 26, 27}, h(n) is new for...

IL-23 is a heterodimeric cytokine composed of the IL-12p40 "soluble receptor" subunit and a novel cytokine-like subunit related to IL-12p35, termed p19. Human and mouse IL-23 exhibit some activities similar to IL-12, but differ in their capacities to stimulate particular populations of memory T cells. Like IL-12, IL-23 binds to the IL-12R subunit IL-12Rbeta1. However, it does not use IL-12Rbeta...
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). In MS, myeloid dendritic cells (mDCs) secrete elevated amounts of IL-23, a potent proinflammatory cytokine, compared to healthy donors. Here, we examined the role of CD46, a complement binding factor, in mDCs by analyzing cytokine and chemokine production in healthy donors and patients with MS. There ...
