چکیده
In the title mol-ecule, C(18)H(11)FN(2)O(4), the fused four- ring system is essentially planar, with an r.m.s. deviation of 0.032 Å. In the crystal, mol-ecules are connected by π-π stacking inter-actions [centroid-centroid distances = 3.5684 (9) and 3.8247 (9) Å] into chains along [100].

Crystal structures of two 2,3-diethylnaphtho[2,3-g]quinoxaline-6,11-dione derivatives
Two new 5,12-disubstituted 2,3-di-ethyl-naphtho-[2,3-g]quinoxaline-6,11-dione compounds were readily synthesized from the commercial dye quinizarin. For 2,3-diethyl-5,12-di-hydroxy-naphtho-[2,3-g]quinoxaline-6,11-dione, (II), C20H16N2O4, the mol-ecule displays a near planar conformation and both hy-droxy groups participate in intra-molecular O-H⋯O(carbon-yl) hydrogen bonds. In the crystal, π-π ...
متن کاملComputational and spectral investigation of 5,12-dihydro-5,12-ethanonaphthacene-13-carbaldehyde.
A conformational search of 5,12-dihydro-5,12-ethanonaphthacene-13-carbaldehyde predicted the presence of twelve conformations. The geometry of the twelve conformations established at the B3LYP/6-31G* level showed only six unique ones. Vibrational frequencies were calculated at the B3LYP/6-31G* level. The calculated vibrational frequencies enabled us to interpret the appearance of two bands corr...

متن کاملSulfasalazine inhibits the synthesis of chemotactic lipids by neutrophils.
Neutrophils metabolize arachidonic acid through the liposygenase pathway to 5-hydroxy-6,8,11,14-eicosatetrenoic acid (5-HETE) and 5,12-dihydroxy-6,8,10,14-eicosatraenoic acid (5,12 diHETE). 5-HETE and 5,12diHETE are potent chemotactic agents and are thought to have important roles in the inflammatory response. In this study we demonstrate the sulfasalazine, at concentrations found in the stool ...
متن کامل2,3-Dimethoxy-5,12-tetracenequinone
The mol-ecule of the title compound, C(20)H(14)O(4), is approximately planar [maximum deviation 0.168 (2) Å]. The two meth-oxy groups are slightly twisted relative to the plane of the 5,12-tetra-cenequinone system, with twist angles of 3.3 (3) and 5.6 (2)°. All O atoms are involved in intermolecular C-H⋯O inter-actions and the mol-ecules are arranged into slipped face-to-face stacks along the b...
