novel analogues of n-piperazinyl fluoroquinolones were prepared and evaluated against a panel of gram-positive and gram-negative bacteria, to study the effect of introducing bulky anthracene and phenanthrene moieties on the antibacterial effects of norfloxacin, ciprofloxacin and gatifloxacin. although most of the novel synthesized compounds had lower antibacterial effects, some derivatives show...

1. 7- and 12-Methylbenz[a]anthracene were converted by rat-liver homogenates into the corresponding hydroxymethyl derivatives, products that are probably the 8,9-dihydro-8,9-dihydroxy and the 5,6-dihydro-5,6-dihydroxy derivatives, and a number of phenolic products. 2. Both hydrocarbons were converted into glutathione conjugates; that from 7-methylbenz[a]anthracene was also formed, together with...

Three dithienylethene derivatives having anthracene substituents (connected at 1-, 2- and 9-positions) were prepared. Although these three derivatives exhibit photochromic reactivity in solution, only one of the derivatives (connected at 2-position) undergoes the photochromic reaction in the crystalline phase. X-Ray crystallographic analysis and DFT calculation revealed that conformation of the...

Eleven derivatives of 7,12-dimethylbenz(a)anthracene were tested for carcinogenicity in Sprague-Dawley female rats by the s.c. injection of 1.0 or 0.1 mg of compound dissolved in 0.1 ml of sesame oil on alternate days for 20 doses. Eight derivatives [7-hydroxymethyl-12-methyl-, 7-formyl-l 2-methyl-, 7-methoxymethyl-l 2-methyl-, 7-acetoxymethyl-l 2-methyl-, 7-benzoyloxymethyl-l 2-methyl-. 7-iodo...

There were substantiated the expediency of the using for the determination of identity of Cassia acutifolia Del. leaves of spectrophotometry and TLC. As the results of the chemical study of Cassia acutifolia leaves there were isolated the predominant components of this plant 1,7-dihydroxy-3carboxyanhraquinone, 8-O-β-D-glucopyranoside of torachrysone, kaempferol-3-O-gentiobioside and on this bas...

The newly designed and synthesized artificial anthracene derivatives possessing a deoxyamino sugar effectively and randomly cleaved proteins, such as bovine serum albumin (BSA) and hen egg lysozyme (Lyso), during photoirradiation using a long wavelength UV light (365 nm) without any further additives. Furthermore, it was found that the cleaving ability of anthracene could be improved by the att...
