In the title compound, C17H17N O4S, the quinoline ring system is nearly planar, with a maximum deviation of 0.0496 (16) Å. A weak intra-molecular C-H⋯O inter-action is observed. In the crystal, C-H⋯O, S-H⋯N and π-π stacking inter-actions between the fused benzene ring of quinoline and the pyridine moieties [shortest centroid-centroid distance = 3.6754 (11) Å] are observed. Inversion-related wea...

Anaerobic decarboxylation of malonate to acetate was studied with Sporomusa malonica, Klebsiella oxytoca, and Rhodobacter capsulatus. Whereas S. malonica could grow with malonate as sole substrate (Y = 2.0 g.mol-l) , malonate decarboxylation by K. oxytoca was coupled with anaerobic growth only in the presence of a cosubstrate, e.g. sucrose or yeast extract (Y, = 1.1-1.8 g.mol malonate-1). R. ca...

Some 2H-chromen-2-one and imine derivatives have been synthesized through a one-pot condensation of aldehydes, diethyl malonate, amine compounds. The compounds obtained characterized using FTIR, NMR, GC-MS, elemental analysis. single-crystal X-ray structure 3-[piperidine-1-carbonyl]-2H-chromen-2-one (2) has presented. Compound 2, recrystallized in the monoclinic space C2/c (no. 15), = 16.654(15...

Malonate, an inhibitor of mitochondrial complex II, is a widely used toxin to study neurodegeneration in Huntington's disease and ischemic stroke. We have shown previously that malonate increased reactive oxygen species (ROS) production in human SH-SY5Y neuroblastoma cells, leading to oxidative stress, cytochrome c release, and apoptotic cell death. Expression of a green fluorescent protein-Bax...

These studies examined, in vivo, the effect of local intrastriatal perfusion of methamphetamine (MA) on dopamine (DA) and glutamate release in relation to changes in striatal DA and serotonin (5-HT) content measured 1 week after treatment. Interactions between the inhibition of energy metabolism and the direct perfusion of MA on long-term decreases in DA and 5-HT content also were investigated....

DL-Phenyl alanine labeled with carbon-14 in the α-position has been synthesized from ethyl[2-14C] acetate as part of a 6-step sequence.

A facile difunctionalization of arylketones with malonate esters via electrochemical oxidation was achieved under mild conditions. A variety of difunctionalized products were obtained in good to excellent yields.
