The influence of 3-methyl-2,6-diphenyl piperidin-4-one (MDPO) and 2phenyl decahydroquinoline-4-one (PDQO) synthesised in the laboratory on hydrogen permeation and corrosion inhibition of mild steel in 1N H2SO4 has been studied using weight loss and various electrochemical AC and DC corrosion-monitoring techniques. Both the compounds inhibit the corrosion of mild steel in H2SO4. Potentiodynamic ...

The inhibition of ABC (ATP binding cassette) transporters is considered a powerful tool to reverse multidrug resistance. Zosuquidar featuring a difluorocyclopropyl-annulated dibenzosuberyl moiety has been found to be an inhibitor of the P-glycoprotein, one of the best-studied multidrug efflux pumps. Twelve 5-oxyisoquinoline derivatives, which are analogues of zosuquidar wherein the dibenzosuber...

The paper discusses syntheses of new nitroxides by structure modifications of known carbocyclic and heterocyclic nitroxides and their diamagnetic precursors, as well a6 syntheses of nitroxides with a functional group in close proximity to the radical centre. It demonstrates a new route to pyrrolidine nitroxides. Much has been focused on 3-imidazoline and 3-imidazoline-3-oxide nitroxides owing t...
