This study aimed to synthesize quinolinone derivatives and investigate their cytotoxic activity. The compound 1-azacoumarin-3-carboxylic acid (2-oxo-1H-quinoline-3-carboxylic acid) was obtained via the cyclocondensation of 2-hydroxybenzaldehyde with diethyl malonate in base catalyst give ethyl coumarin-3-carboxylate, followed by ammonolysis ester (ethyl coumarin-3-carboxylate) ammonia presence ...

Ethyl alcohol is one of the United States and world's major chemicals. Beverage alcohol in the United States must be prepared from cereal grains or other natural products. The U.S. industrial alcohol market has remained relatively stable for several years at approximately 300 million gallons annually. Most of this has been produced synthetically from petroleum raw material (gas and oil). These ...

2. Fusel or fousel oil is a term generally applied to amylio alcohol, but practically fusel oil is a mixture of several homologous alcohols ; homologous being an expression employed in organic chemistry to denote a series of compounds each member of which differs from the preceding one by an addition of CH2. 3. The fermentation of pure sugar yields ethyl alcohol, ordinary spirits of wine, and g...

The title compound, C(14)H(11)ClFNO(2), the phenyl ring (A), the chloro-fluoro-phenyl ring (B) and the central ketone O/C/O group (C) are not coplanar, with dihedral angles B/C = 31.6 (2), A/B = 21.3 (2) and A/C = 50.1 (2)°. The crystal packing is stabilized by N-H⋯O and C-H⋯O inter-actions.

The article presents the results of adaptation spectral-luminescent method for establishing alcohol nature regarding liquids a non-industrial manufacturing based on rectified ethyl alcohol, which are prevailing objects submitted forensic examination materials, substances, and products alcohol-containing liquids. authors describe particularities sample preparation, calculation formulas, limitati...

Sixteen new phthalimide derivatives were synthesized and evaluated for their in vitro anti-microbial, anti-oxidant and anti-inflammatory activities. The cytotoxicity for all synthesized compounds was also determined in cancer cell lines and in normal human cells. None of the target derivatives had any cytotoxic activity. (ZE)-2-[4-(1-Hydrazono-ethyl) phenyl]isoindoline-1,3-dione (12) showed rem...

Hexane extracts of epicuticular wax from cv. Gala apples were noted to have an unusual, broad absorbance maximum at approximately 258 nm, which led us to isolate and identify the primary UV-absorbing compounds. Column and thin-layer chromatography yielded a fraction that gave a series of paired, 260-nm-absorbing peaks on C(18) HPLC. These were shown to be a family of phenolic fatty acid esters,...

Distribution and levels of octopamine (OA), one of the biogenic amines in the invertebrate nervous system, may have significant effects on insect physiological processes including growth, feeding and reproduction. In this paper capillary gas chromatography with electron capture detection (GC-ECD) and mass selective detection (GC-MS) were used to determine the content of OA in Blattella germanic...

reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methyl-imi...
