A new hexadentate, tripodal 8-hydroxyquinoline ligand (QH3) and its trivalent metal chelates (MQ, M=Al3+, Ga3+, In3+) with hemicage structures have been prepared and the electrochemical and photophysical properties systematically studied. The hemicage structure of the metal complexes was characterized by 1H NMR, indicating a pure facial geometry, in contrast to their uncaged cousins with 8-hydr...

This report validates a technique of separating and labeling canine platelets using indium-1 1 llabeled 8-hydroxyquinoline (Yn-8-HQ). Platelet survival time in six normal dogs was 6.3 ? 0.7 (SD) days. Labeling effisiency using this technique was 51.8 + 9.2% (SEM) and elution loss of 11LIn-8-HQ label from platelets was consistently less than 4%. Vn label offers no observable advantages over the ...

A series of manganese(I) tricarbonyl complexes formulated as [Mn(8-HQ)(CO)3Imd] (HQ = hydroxyquinoline and Imd imidazole derivatives) was synthesized fully characterized. These structures could be easily accessed from a common dimeric edifice [Mn2(8-HQ)2(CO)6]. The structure this complex has been confirmed by X-ray diffraction studies. Its reaction with range derivatives (Imd) yielded the monom...

in order to study the physiological effects of some of the essential oils in comparison with 8-hydroxyquinoline in cut lisianthus flowers (eustoma grandiflorum l.), an experimental was conducted in a completely randomized design with three replications. traetments included 8-hydroxyquinoline, essential oil of australian cheesewood (pittosporum undudatum) and rosmary oil(rosmarinus officinalis) ...

Abstract This study was carried out in the laboratory of Shangqiu Institute Technology, Henan to investigate effect a different combination inorganic salt on quality and physiological characteristics cut flowers (CFs) Perpetual Carnation. Furthermore, find best preservation solution that can enhance ornamental value CFs Carnation prolong its vase life. Sucrose, 8-hydroxyquinoline, paclobutrazol...

Glycerol:NAD+2-OXIDOREDUCTASE (EC 1.1.1.6) was purified to homogeneity from a mutant of Escherichia coli K12 that uses this enzyme, instead of ATP:glycerol 3-phosphotransferase (EC 2.7.1.30), as the first enzyme for the dissimilation of glycerol. Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate shows a subunit of 39,000 daltons. During electrophoresis under nondenatu...
