Fungal laccase can be detected with the nonautooxidizable laccase specific compound, syringaldazine, in the presence of tyrosinase and per oxidase. Data are presented from tests with the azine derivative of numerous fungous sporophores and associated decayed wood tissues from various localities in Wisconsin and Oregon. Syringaldazine is shown to be a reliable replacement and more specific rea...
The synthesis, structural, electrochemical, optical, and electronic structure properties of a new azine-thiophene semiconductor family are reported and compared to those of analogous oligothiophenes. The new molecules are: 5,5'-bis(6-(thien-2-yl)pyrimid-4-yl)-2,2'-dithiophene (1), 5,5'-bis(6-(5-hexylthien-2-yl)pyrimid-4-yl)-2,2'-dithiophene (3), and 5,5'-bis(6-(thien-2-yl)pyridazin-3-yl))-2,2'-...
Oligonucleotides carrying novel fluorescent compounds with a dipolar isoquinoline imidazo[1,2-a]azine core were prepared. Analysis of the melting curves demonstrates that DNA duplexes carrying these fluorescent labels at their ends have a slight increase in DNA duplex stability. The UV absorption and fluorescent properties of the oligonucleotide conjugates were analyzed. The fluorescent label i...
The title compound, C(15)H(14)ClF(3)N(4), was synthesized from 3,6-dichloro-pyridazine and 1-[3-(trifluoro-meth-yl)phen-yl]piper-azine. The piperazine ring is flanked by 3-chloro-pyridazine and 3-trifluoro-methyl-phenyl rings and adopts a chair conformation, whereas the 3-chloro-pyridazine and 3-trifluoro-methyl-phenyl rings are planar, with maximum deviations of 0.0069 (13) and 0.0133 (14) Å, ...
