Fungal metabolism of acenaphthene by Cunninghamella elegans.
The filamentous fungus Cunninghamella elegans ATCC 36112 metabolized within 72 h of incubation approximately 64% of the [1,8-14C]acenaphthene added. The radioactive metabolites were extracted with ethyl acetate and separated by thin-layer chromatography and reversed-phase high-performance liquid chromatography. Seven metabolites were identified by 1H nuclear magnetic resonance, UV, and mass spe...
متن کاملSynthesis of a phosphapyracene via metal-mediated cyclization: structural and reactivity effects of acenaphthene precursors.
Metal-mediated synthesis of a new heterocycle, 1-phenyl-phosphapyracene (Ph-4, Ph-PyraPhos), by tandem phosphination/cyclization of peri-substituted 5-bromo-6-chloromethylacenaphthene (3) was investigated for comparison to Pt-catalyzed formation of 1-phosphaacenaphthenes (2, AcePhos) from the analogous naphthalene precursor (1). Reaction of PH2Ph with , NaOSiMe3 and a Cu catalyst gave ; a Pt ca...
متن کاملSulfur Trioxide and Oleum
Sulfur trioxide (SO3) and oleums are generally aggressive materials with complicated properties. They are widely used in the process industries. Their main feature is the violent reaction of SO3 and water that occurs in both the liquid and the vapor phase. Oleum (or fuming sulfuric acid) is a solution of sulfur trioxide in 100% sulfuric acid. Its strength is expressed as weight percentage free ...

15 صفحه اولSynthesis and biological evaluation of novel acenaphthene derivatives as potential antitumor agents.
Twelve novel acenaphthene derivatives have been synthesized. The structures of all compounds were confirmed by ¹H-NMR, MS and elemental analysis. Their antitumor activities were evaluated in six human solid tumor cell lines, namely non-small cell lung cancer (H460), human colon adenocarcinoma (SW480), human breast cancer cell (MDA-MB-468 and SKRB-3), human melanoma cell (A375) and human pancrea...
