Dinuclear rhenium(I) complexes having a fac-[Re(CO)3](+) moiety of general formula fac-[Re2(CO)6(hq)2] have been synthesized in excellent yield by reacting [Re(CO)5Cl] with Hhq in a ratio of 1 : 1 in toluene in an argon atmosphere. Here hq(-) is the deprotonated form of 5-phenylazo-8-hydroxyquinoline (Hhq(1)), 5-(2-naphthylazo)-8-hydroxyquinoline (Hhq(2)) and 5-(2-fluorineazo)-8-hydroxyquinolin...

A Pseudomonas sp. isolated from sewage by enrichment culture on quinoline metabolized this substrate by a novel pathway involving 8-hydroxycoumarin. During early growth of the organism on quinoline, 2-hydroxyquinoline accumulated as the intermediate; 8-hydroxycoumarin accumulated as the major metabolite on further incubation. 2,8-Dihydroxyquinoline and 2,3-dihydroxyphenylpropionic acid were ide...

These analyses show that this cyclic A M P phosphodiesterase.contains at least 15ng of zinc per activity unit. The sodium dodecyl sulphate/polyacrylamide-gel electrophoresis of fraction 18 suggests that the specific activity of pure enzyme is at least 104 units/mg, and the results of Fujimoto et al . (1974), obtained at 37"C, suggest it may be as high as 160 units/mg at 30°C. Thus 1 mol (65000g...

The possibility of imparting an antibacterial effect to cellulose tissue dyed with the product azo coupling diazotized 4,4’-diaminostilbene-2,2’-disulfonic acid 8-hydroxyquinoline has been shown. It was found that fabrics by fixing dye a silver salt have significant effect, which lasts at least 10 washings.
