RNA was isolated by a phenol extraction method from mouse embryo cells treated in culture with either [G-~H]-7 methylbenz[a]anthracene or [G-:'H]-7-methylbenz[a]anthracene 5,6-oxide (the K-region epoxide). The RNA was degraded to ribonucleosides, mixed with ultraviolet-absorbing quantit ies of the epoxide ribonucleoside products isolated from RNA that had reacted with 7-methylbenz[a]anthracene ...

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...

An anisotropic tunnel microporous crystal was prepared. Active transportation of anthracene as a guest molecule in the anisotropic tunnels was observed. The direction of anthracene movement implies that the anisotropic tunnel did not work as a flap-check valve. The direction of the movement was consistent with that caused by a Brownian ratchet.

In an attempt to simplify the technique for measuring extracellular fluid volume with sulfur-35, a weak beta-emitting radioisotope, an anthracene cell was devised with constant volume and geometry. Anthracene crystals emit a blue flourescent light when exposed to ionizing radiation. Different forms of anthra cene cells have been devised. All consist of packed anthracene crystals in a con tamer ...

Benz[a]anthracene is a ubiquitous environmental contaminant formed during the incomplete combustion of organic material. Some of the metabolites of benz[a]anthracene are known to be toxic and carcinogenic. In this investigation, benz[a]anthracene-induced oxidative damage to lymphocyte DNA was evaluated with the Comet assay (single cell gel electrophoresis). The level of oxidative DNA damage cau...

The title mol-ecule, C58H44N6S8, has point symmetry 2 (in the Schönfliess notation C2). The related crystallographic twofold axis bis-ects the central ethane bond while it is parallel to the monoclinic unique axis of the unit cell. The dithiole=C-C=dithiole torsion angle is 103.7 (4)° and the triazole-anthracene moieties adopt a pincer-like conformation. The crystal structure features C-H⋯S and...

Due to its highly conjugated panel-like structure and unique photophysical chemical features, anthracene has been widely used for fabricating attractive functional supramolecular assemblies, including two-dimensional metallacycles three-dimensional metallacages. The embedded anthracenes in these assemblies often show synergistic effects on enhancing the desired luminescent properties. This revi...

The techniques of chemical ligation have attracted great attention as an alternative to enzymatic joining of DNA ends. Here we introduce the photoligation of anthracene-modified ODN conjugates through anthracene cyclodimer formation. The effect of the positions and the kinds of single base mismatch on the template was evaluated using eight templates with one-base displacements. We found out tha...
