In the title compound, C28H24N2O7S, the carbazole system is essentially planar, with a maximum deviation of 0.0644 (19) Å for the C atom connected to the 4,5-dimeth-oxy-2-nitro-phenyl group. The dihedral angle between the carbazole moiety and the dimethoxy-substituted nitrophenyl ring is 58.55 (7)°. The sulfonyl group forms two intra-molecular C-H⋯O bonds with the adjacent carbazole system, for...
Two promising uncharged reactivators for inhibited human BChE and AChE have been described. These compounds show an ability to reactivate VX-inhibited BChE largely superior to those of known pyridinium aldoximes. Moreover, these oximes also exhibit a good ability to reactivate VX-, tabun- and paraoxon-inhibited human AChE.
The synthesis of nano-sized particles of NU-1000 (length from 75 nm to 1200 nm) and PCN-222/MOF-545 (length from 350 nm to 900 nm) is reported. The catalytic hydrolysis of methyl paraoxon was investigated as a function of NU-1000 crystallite size and a significant enhancement in the rate was observed for the nano-sized crystals compared to microcrystals.
We have investigated the effect of electromechanical activity on the molecular forms of acetylcholinesterase (AChE) in cultured embryonic rat myotubes. Both globular and asymmetric forms of AChE are present on the 5th day of culture when myotubes are just beginning to fibrillate. Between days 5 and 8, the 4 S (G1), 10 S (G4), and 16 S (A12) forms increase dramatically, and appreciable 12.5 S (A...
Nicotinic stimulation induces Tristetraprolin over-production and attenuates inflammation in muscle.
Cholinergic signaling suppresses inflammation in blood and brain and attenuates apoptosis in other tissues, but whether it blocks inflammation in skeletal muscle under toxicant exposure, injuries and diseases remained unexplored. Here, we report nicotinic attenuation of inflammation and alteration of apoptotic protein expression pattern in murine muscle tissue and cultured myotubes, involving t...
Dr0930, a member of the amidohydrolase superfamily in Deinococcus radiodurans, was cloned, expressed, and purified to homogeneity. The enzyme crystallized in the space group P3121, and the structure was determined to a resolution of 2.1 A. The protein folds as a (beta/alpha)7beta-barrel, and a binuclear metal center is found at the C-terminal end of the beta-barrel. The purified protein contain...
