Effect of 2-n-heptyl-4-hydroxyquinoline N-oxide on proton permeability of the mitochondrial membrane.

Inhibition of dihydrocozymase-oxidase activity of heart-muscle preparations and of certain cell-free bacterial preparations by 2-heptyl-4-hydroxyquinoline N-oxide.

a preliminary communication (Jackson & Lightbown, 1956) we have reported the inhibitory effect of heptyl N-oxide on the dihydrocozymaseoxidase activities of heart-muscle succinic oxidase preparations and of certain cell-free preparations of Staphylococcus aureus, Eacherichia coli, Proteus vulgariw and Bacillus pumilu&. The present paper includes a more detailed account of this work, together wi...

Studies on lipoxygenase inhibitors. II. KF8940 (2-n-heptyl-4-hydroxyquinoline-N-oxide), a potent and selective inhibitor of 5-lipoxygenase, produced by Pseudomonas methanica.

Pseudomonas methanica KY4634 was found to produce 5-lipoxygenase inhibitor designated KF8940, MY12-62a and MY12-62c. The inhibitors were purified by solvent extraction, silica gel column chromatography, reversed-phase low pressure liquid chromatography and crystallization. The chemical structures of KF8940, MY12-62a and MY12-62c were determined to be 2-n-heptyl-4-hydroxyquinoline-N-oxide, 2-n-h...

Selective inhibition by 2-heptyl-4-hydroxyquinoline N-oxide of certain oxidation-reduction reactions.

Effect of nano Zinc Oxide on gas permeation through mixed matrix poly (Amide-6-b-Ethylene Oxide)-based membranes

Poly (amide-6-b-ethylene oxide)/Zinc Oxide (PEBA/ZnO) mixed matrix membranes were fabricated using ethanol/water as solvent by solvent casting method. The concentration of ZnO in membrane was set to 0.1 wt.% and the synthesized membranes were characterized by AFM and FTIR. Effects of ZnO nanoparticle on CO2, CH4 and N2 permeabilities, and CO2/N2<...
