Furan derivatives. ЬХХП. Synthesis and some properties of l-(5-nitro-2-furyl)- -2- (5-aryl-2-furyl)ethylenes
Wittig reaction has recently been applied also in the preparation of 5-nitrofuran derivatives of ethylene [1—5]. The quoted syntheses were accomplished starting either from 5-nitrofurfuryl halides which were converted into 5-nitrofurfurylidenephosphoranes and subsequent condensation of the latter with carbonyl compounds [1—4], or the intermediate phosphoranes were prepared from other furfuryl h...
متن کاملNovel N-2-(Furyl)-2-(chlorobenzyloxyimino) ethyl Piperazinyl Quinolones: Synthesis, Cytotoxic Evaluation and Structure-activity Relationship
Quinolone antibacterials are one of the most important classes of pharmacological agents known as potent inhibitors of bacterial DNA gyrase and topoisomerase IV that efficiently inhibit DNA replication and transcription by generating several double-stranded DNA break. Some quinolone derivatives demonstrated inhibitory potential against eukaryote topoismarase II and substantial dose-dependent cy...

متن کاملSynthesis and studies on antidepressant and anticonvulsant activities of some 3-(2-furyl)-pyrazoline derivatives.
Twelve 1-phenyl-, 1-thiocarbamoyl- and 1-N-substituted thiocarbamoyl-3-(2-furyl)-5-phenyl/(2-furyl)-2-pyrazoline derivatives were synthesized. The chemical structures of the compounds were proved by IR, (1)H NMR, Mass spectrometric data and microanalyses. The antidepressant activities of the compounds were investigated by Porsolt's behavioural despair (forced swimming) test on albino mice. 1-N-...
متن کامل2-(2-phenylethyl)chromones from Chinese eaglewood.
2-(2-Phenylethyl) chromones and a 2-(2-phenylethenyl) chromone, were isolated from the ethanolic extract of Chinese eaglewood. Their structures were determined on the basis of extensive analyses of spectroscopic data. Among those, one showed significant neuroprotective activities against both glutamate-induced and corticosterone-induced neurotoxicity in P12 pheochromocytoma and human U251 gliom...
